I like to know if a seed has germinated before it ever goes into soil or a piece of hydroponic Rockwool. There’s an easy way to know if you have viable seed and that is through a technique that simply requires a sheet of paper towel, a container with a lid, water and a consistently warm location 72ºF-76ºF. You can learn more about how to set up these pre-germination conditions on our blog here, but if you’re already familiar with this method, here is a quick visual of what you’re looking for with pepper seeds and when to transfer them to either soil or Rockwool (Rockwool is used for soilless hydroponic / aeroponic growing systems).
The seed that is circled in green is ready to gently transfer to soil or Rockwool using a sanitized tweezer. (To sanitize your tweezer, simply clean with rubbing alcohol.) The seed circled in yellow shows swelling and indicates that you should probably check it the next day as the root is getting ready to emerge.
The other seeds are slightly swollen showing that they are still in the process of germinating. Do not give up on seeds that are slower to germinate — sometimes they can take up to 10 days even when you are providing ideal conditions. Check moisture daily and if paper towel smells funky, swap out for a new paper towel and rewet and put back into germination chamber container.
Below is a photo showing germinated seed that has been placed into Rockwool (see number one below). If you are growing in a hydroponic growing system such as a Tower Garden or Aerogarden, you’ll want to place your seed in Rockwool instead of soil. (Coco Coir is also a good alternative growing medium for hydroponics or aeroponics assuming it has support to hold material together such as in a mesh net.)
I like to cover my seeds with vermiculite. Some hydroponic growers insist that this step isn’t necessary, but I like to make sure my seeds receive adequate moisture throughout these early stages of growth especially. Strong healthy seedlings, make for strong healthy plants. I use this process for pepper, tomato, and eggplant seeds and any seeds that are not super small. Remember, some seeds need light to germinate (like lettuce), so be sure to reference our cheat sheet before starting seeds to know if your seed needs light, no light, or if it doesn’t matter.
Rockwool is a fantastic growing medium as it has air pockets and is good at holding water. Keep moist, but not sitting in water.
Hope that helps! Remember, we have a great assortment of hydroponic-adapted tomato and pepper seed available in the seed store. Be sure to check it out!
Yet another outbreak due to tainted lettuce salad in the first few months of 2022. At latest report, 17 have been sickened across 13 states and two unfortunate deaths in a recent listeria outbreak according to the U.S. Centers for Disease Control and Prevention (CDC).
The salads, which were recalled by Dole in December and are currently under an active investigation by the CDC, include a variety of different mixes. They were sold in either bags or plastic clamshell packaging, according to the agency, which said they include Caesar salads, mixed greens, and garden salads.
The salads that were tainted are sold under several different brand names such as Ahold, Dole, HEB, Kroger, Lidl, Little Salad Bar, Marketside, Naturally Better, Nature’s Promise, President’s Choice, and Simply Nature, the alert said.
The recalled salads have “Best if used by” dates between Nov. 30, 2021, and Jan. 9, 2022, the CDC said. They also have lot codes that start with the letters “B,” “N,” “W” or “Y.”
For those who suspect they may have the salad in their refrigerators, the CDC recommends to “throw them away or return them to where you bought them.” The agency further recommends that people clean their refrigerators, surfaces, or items that might have touched the recalled products as listeria can survive “in the refrigerator and can easily spread to other foods and surfaces.” If you suspect you have this in your refrigerator or have consumed this product, please reach out to the CDC immediately.
This is not the only incident. The CDC said that it is also investigating another listeria outbreak connected to Fresh Express packaged salads, which occurred in December of last year and led to 10 hospitalizations and one death. That recall includes use-by dates with the product codes Z324 through Z350. Affected brands include Bowl & Basket, Giant Eagle, Fresh Express, Marketside, O Organics, Little Salad Bar, Signature Farms, Simply Nature, Weis Fresh from the Field, and Wellsley Farms, said the agency.
According to the Mayo Clinic, a “listeria infection is a food borne bacterial illness that can be very serious for pregnant women, people older than 65 and people with weakened immune systems.” And that “healthy people rarely become ill from listeria infection, but the disease can be fatal to unborn babies, newborns and people with weakened immune systems.” Symptoms include fever, muscle aches, nausea, chills, diarrhea, while more serious symptoms can include stiff neck, headache, convulsions, and a loss of balance, the clinic’s website says. “Symptoms might begin a few days after you’ve eaten contaminated food, but it can take 30 days or more before the first signs and symptoms of infection begin.”
This is not the first time outbreaks that result in the loss of life have been cause by those eating bagged salad or greens purchased from big box retailers. In the busyness of life, we trade food security and nutrition for convenience.
I didn’t learn until about five years ago, that most of our lettuce comes from Salinas, California. For those of us living on the East Coast, that means our greens have to travel approximately 3,000 miles which takes on average about 10 days to go from field to our table. When you think about nutrients lost for every day post-harvest, we are simply eating old food.
Here’s the thing… it doesn’t need to be this way. With changing a few habits, we can have greens at home in a number of ways, but the easiest by far that I have found is growing greens in my hydroponic / aeroponic growing system, the Tower Garden. I can start seeds for greens every couple of weeks and have a constant supply of greens, right in my home, 365 days a year. And when I harvest the greens, I can simply go from my vertical garden growing system to my table within literally minutes with a quick wash and spin dry if I wanted to do so! (Normally I harvest my greens in the morning when they are at their peak nutrition and the chill them after cleaning the leaves and spinning the leaves dry before fixing a salad.)
I’ve heard it time and time again when people balk at the price of a hydroponic / aeroponic Tower Garden. I don’t blame them. I know I did the same thing at first. And then my husband had a heart attack and suddenly the price of that tool to grow food seemed to PALE in comparison to the medical bills that piled up and the new life of treatment we faced post-heart attack.
I remember, one of THE BEST decisions I made following his heart attack was to purchase three Tower Garden vertical garden growing systems (we got the three Family Pack). We opted for the payment plan and paid on them for only a year. We looked at it as if we were paying for insurance but instead investing in the health of our family. Boy were we right! Now, we are going into our fifth year of growing food in these full- paid-for vertical garden growing systems. They have easily paid for themselves over and again; I cannot begin to describe how many fresh greens we have eaten off of these Tower Gardens!
If you aren’t willing or able to invest in a growing system like this, at least start with something smaller, like an Aerogarden that can sit on your kitchen counter. There are outdoor options you can cover as well if you prefer that use soil, but I’ve found that using a growing system that circulates the same water and nutrients not only saves water, but it frees me up from having to babysit watering something growing in soil every day. I’m a busy homeschooling mom of five — I need things automated as much as possible. I simply add checking on the Towers 1 – 2x a week to my work flow at home and smile big when I have the food and herbs at my fingertips when it comes time to make dinner. You can learn more here if you’re interested or send us a message and we will reach out to you to answer any questions.
And if you’re buying salad kits…. Stop. Stop trading what seems to be a convenience for what you think is healthy. They are not healthy. You’re eating old food. Unless it says right on the packaging that it was grown locally, do not buy it. Grow it at home. And be careful of anything that had to be processed (ie: cut and assembled). You’re putting a lot of faith into someone else.

I just read this announcement (which I will also share with you, because it could affect anyone purchasing these items from the produce aisle…), but before I share, let me just say that there is no reason in my opinion on why individuals cannot grow their own greens. Enlighten me — tell me in the comments below why greens cannot be grown. My inquiring mind wants to know.
I literally just planted a tray of kale seeds yesterday to grow out into our cool fall days. In fact, fall and winter here in Zone 7B is a fantastic time to grow kale, because there is less pest pressure.
If you have never grown kale, you are missing out on one of the most convenient and easiest plants you can grow. You just harvest leaf-by-leaf from the bottom of the stem upwards as it grows and it keeps giving more-and-more leaves to nourish you week-after-week through the cool season.
When we get down to freezing temps, just cover with a row cover material of some sort or if in a planter, roll it in at night into the garage and back out in the day time. Some kale actually tastes sweeter it seems with frost. Or, like me, you could invest in a Hydroponic vertical garden growing system with grow lights like the Tower Garden and grow kale or greens 24/7/365.
Self-sufficiency is not only the healthiest option for you and those you love, but it’s a wonderful feeling to just enjoy the work of your hands. If you have a moment, check out EWG’s Dirty Dozen list. Notice what is on it? And if you’ve been purchasing produce from Kroger — specifically kale — take note of this important announcement just released moments ago from the Georgia Department of Agriculture Food Recall:
The Kroger Co. (NYSE: KR) is recalling its 16-ounce Kroger bagged kale product, produced by Baker Farms, due to possible listeria monocytogenes contamination. This action is being taken in cooperation with the US FDA. To date, no illnesses related to this product have been reported.
This recall includes 16-ounce bags of Kroger branded Kale (see picture below), with the UPC 11110-18170 with a best by date of 09-18-2021, which is printed on the front of the package below the light blue bar. All affected products were pulled from the Produce departments on Sept. 16, 2021.
Baker Farms is recalling their Baker Farms, Kroger & SEG Grocers brand names of Kale, 1 lb plastic bags with BEST BY 09-18-2021107020-21832 due to contamination of Listeria monocytogenes. Products affected by this recall can be found here.
On 9-15-2021 the firm was notified by a customer that the product test positive for Listeria monocytogenes. The products were distributed between 8/30/2021 – 9/1/2021. These products were packaged in clear plastic and sold primarily in retail stores located in the States of: AL, AR, FL, GA, LA, MO, MS, NC, NY & VA. No illnesses have been reported to date.
So in summary, grow kale. Especially now. And eat what you grow. You might just fall in love with growing your health gardening in the process.
This time of year, many a gardener will begin breaking out their seeds from storage and gather up their recent purchases in preparation for the upcoming growing season. With earnest, one cell tray or by one rock wool at a time, life will begin inside the gardener’s abode, protected from the cold weather outside.
Seed starting, used to be an annual event for me until I realized the importance of succession planting. If I wanted to have a continual supply of greens or move from one season to the next seamlessly, a little bit of planning was all I needed to do the trick.
If I was going to do succession planting, I needed to make it part of my everyday planting and tending tasks (even if all it means is a quick glance to check moisture levels or that your “babies” (as I affectionately call them) are growing as they should was the only task that day.) And as an everyday task, it needed to be part of my environment. The end result to succession planting throughout the year? A seed starting station.
If you’re only planting seeds one time a year, I encourage you to read on and challenge yourself to look at seed starting in a whole new light (pun intended). We want to set you up for success for the ENTIRE growing season ahead!
What is a Seed Starting Station?
Okay, I’m probably being “Captain Obvious” here, but a Seed Starting Station contains everything you need to start seeds. If I may recommend a few tips as you consider setting up your own Seed Starting Station:Your Seed Starting Station needs to be in a location where you walk by it at least once a day; two times or more a day is even better. Why? Seedlings need nurturing. Watching that they have proper light, temperature, moisture, and humidity levels are all key to successful strong seed starts.
Your Seed Starting Station need to have the proper temperature.
Temperatures do matter with germination and each seed / plant has different temps they prefer to germinate at and a “sweet spot” temperature range. For example, warm season plants typically prefer to germinate at temps above 65ºF. On the flip side, cool season plants, typically prefer to germinate at cooler temps. Spinach, for example, can be started in a container between two wet paper towel sheets in the refrigerator and after about 7-10 days you’ll see the root emerge. At this point, you can move it into soil or a wet rock wool and allow it to continue to grow into a young seedlings under bright light while maintaining high 60º-low 70ºF temps.
Seed heat mats can be a great tool for warming soil or rock wool when you set a tray on it. Just be careful to not overheat the young seeds. A thermostat on your heat mat can keep it in the proper range. Below is a quick cheat sheet for common veggies of optimal temperatures seeds typically germinate at:
Optimum Range (F)
Source: PennState Extension. Adapted from Kemble and Musgrove (2006) (Soil temperatures should be taken by inserting a soil thermometer 3-4 inches deep into the soil surface and noting temperature.
Your Seed Starting Station Needs Bright Light
Seedlings need a lot of light once they emerge — a nice bright strong light. If you don’t have a green house that can be temperature controlled for heat and cool air, you will need to grow your seedlings indoors. That means you will need artificial lighting intended for growing plants. Lighting could get real technical quick, so I’m going to try to keep it simple. When it comes to lighting and seed starting you need to keep three things in mind to make adjustments as needed to ultimately save money on seeds:
INTENSITY: You need to have enough lighting. • LED bars: 8–10 inches apart from each other • T5 fluorescents: 4–5 inches apart from each other
COVERAGE: You need to place lighting in the sweet spot — not too far from seedlings. • LED bars (like Phillips): 8–12 inches away from seedlings • T5 fluorescents: 5–6 inches away from seedlings
DURATION: You need to leave lights on long enough. 14-18 hrs a day
Your light needs to be bright (this is like the one we use) and you need to have a way to adjust the light so that it is the correct distance from the seedling. And if you’re planting into a hydroponic growing system where your seedling will mature into an adult plant, you’ll want lights that can be adjusted distance-wise from the plant (closer when they are young and further away about 8″-10″ when they are older). If you’re using a Tower Garden HOME or Tower Garden FLEX, these are the lights you will want to invest in as they can be adjusted from the plant as it grows and they have a built in timer making it easy to set it and go about your life never having to worry about the lights turning on and off again.
Don’t rely on a window with sun coming in as it will make your seedlings “leggy” where they stretch for the light and ultimately that makes them weaker plants as they mature. Today’s windows have a UV rating which actually blocks the essential UV light that seedlings crave. The window is designed to protect your home interior textiles such as the furniture, drapes, and carpet from fading — it is not taking into account seed germination needs at all.
Some love to say “You can just start your seedlings in your Tower Garden — I do it all the time.” A couple of cautionary words are needed when you hear or read this advice posted in social media groups. Simply, don’t do it. Seedlings started in this manner often become leggy and are overall weaker plants when they mature. Secondly, you can “burn” your tender seedling with high levels of nutrients that other mature plants may be getting within your growing system, as seedlings don’t require as much nutrients when they are teeny tiny. Remember to, instead, start your seedlings off strong in a Seed Starting Station under bright grow lights. Look for a light that has all the color spectrum of the sun and avoid cheap $20-$30 grow lights as they are just not strong enough for seedlings to thrive. We recommend a grow light like this that has a full-spectrum. A decent grow light for seedlings will cost between $60-$100. I’ve also used my Aerogarden Harvest as a light for seedlings when I don’t have anything growing in the ports.
You’ll want to keep a quick reference to the needs of different seeds.
Not all seeds need darkness or to be covered to begin the germination process. Some require light to germinate like lettuce. Some need to be scarified (slightly chipped) or go through a cold period before they will germinate. We recommend printing off our Seeds That Require Special Treatment Reference Chart and laminating it or sticking it in a 3-ring binder sheet protector to use as a quick reference (or just bookmark our reference page and come back to it as you need to).
Your Seed Station needs to have supplies relating to starting seeds and nurturing stored nearby
Here’s a list of some common supplies I use for soil and a list for common supplies I use for hydroponics.
Soil: • Seed starting tray cells, recycled containers that can be repurposed as small pots, or small paper pots • potting mix or screened peat moss • worm castings (to mix into your potting mix) (Note: don’t purchase and ship during hot months as temps of 85ºF in shipment will begin to kill beneficial bacteria in castings.) • access to a water source and/or some sort of watering can to “water in” seeds • seeds you intend to plant (those that are not in the freezer) • plant tags • permanent marker • and a tray to rest your seed starts on and move them easily from under your grow light to outdoors as temps allow. • heat mat with temp gauge • grow light
Now to the best part. Your own personal produce section!
To have a continual harvest, you’ll want to implement a sequential planting system. Pick a day that you are at your leisure (i.e.: Sundays are usually a restful day for most folks) and put a reminder on your calendar to plant at a certain time every week or every two weeks paying attention to your growing conditions (i.e.: indoor, cool season, warm season) and available space.
Let’s say you want to have a continuous supply of Bibb Lettuce. If you have a 28 port Tower Garden, you can plant 4 rock wools with Bibb Lettuce seed making sure to include a couple extra seeds per rock wool of which you’ll thin down as they germinate to the strongest one. You’ll repeat this process, planting several lettuce seeds into a single rock wool cube, filling four cubes total. As shown in the below planting chart, by week 4, your week 1 seedlings will be ready to transfer into your system. With each passing week, you’ll put the four seedlings that are ready from previous week plantings into the next row up of your vertical hydroponic / aeroponic Tower Garden. By week 10, you will have harvested your row 1 Bibb Lettuce (four ports = four heads of bibb lettuce to feed a typical family of four for a week). Once your lower lettuce has been harvested (pulled out of the port), the following week, replace the net pots and wipe down the port entrance with a cotton ball with alcohol on it and put a new clean net pot in it’s place. You are ready to plant the next set of four seedlings in these empty ports. As you continue to harvest up the vertical garden, you will clean each port and then plant the next seedling into it.
Note, if you are growing outdoors, sequential planting will get trickier, because temperature will be a variable. As temps raise towards summer time, bibb lettuce will begin to bolt (or go to seed) quicker or go limp if it is not a heat tolerant variety. This type of sequential planting works best if growing greens indoors and if the green has a 6-week grow cycle. This could work for Bok Choy and most greens. Consider putting some herbs like chives in the top row… these are cut and come again meaning that once they are a certain height, you can start cutting them 3″-4″ from the base of the plant and they will continue to grow from the center. Keep in mind that at some point, you will need to clean your system and restart the process, but in theory, if growing indoors, plants should continue to grow at a steady rate if you get in the habit of planting enough to fill four ports each week.

Why you should be growing your own arugula instead of buying from the grocery store or Big-Box Retailer
You know how you go to a fancy restaurant and they bring you your salad course and before they leave your table they offer fresh pepper for your salad and with your permission proceed to grind cracked pepper onto your salad? Think of arugula as your cracked pepper of the salad world.
Why Grow Arugula and How To Use It
I wanted to feature Arugula, because I just don’t think people understand how versatile this plant truly is and that it is beneficial in so many ways. It is chalk-full of beneficial nutrients (which we will cover later in case you wanted to know) while also being low in calories.
It is ideal for new home gardeners in building confidence of gardening skills as it grows quickly from seed (aptly nicknamed “Salad Rocket” in some countries) and can begun to be harvested off of and tossed into salads with other greens when the leaves are still young and small at 2″-3″ in length. (Note: If you leave the center 3-4 leaves, it will continue to produce as a cut-and-come-again plant.) Arugula is often found in the produce aisle in salad greens mix and called “mesclun”.
Mature Full-Grown Leaves and How to Use Them
I as a mother of five know that life can get busy, so if you fall behind on harvesting leaves when small and the plant gets more mature, that’s okay! It will be “spicier” or “peppery” in taste as a mature plant. Take these 6″-8″ long leaves and slice them from tip to base into 1/4″ or thinner strips and sprinkle over your salad or mix in (think of it like your freshly ground peppercorn). Diced leaves can even be added to dishes that call for cilantro or parsley, or mixed into pastas, side dishes, put on top of sandwiches, in wraps and/or added to soups. Its flavor compliments goat cheese, balsamic vinaigrette, tomatoes, olive oil and garlic, making it perfect to blend into dips or spreads.
Arugula can also be added to your basil pesto as added flavor or if you like the peppery flavor, you can substitute arugula in place of basil and make an entire pesto out of arugula leaves. We like this happy medium of a pesto recipe in particular over at PCOSbites. It’s great if you are looking for something that isn’t the same ol’ pesto recipe, but full of nutrients while still tasting delicious. We think of it as the new “elderberry syrup” as an immune-boosting meal for our family.
We also love to add arugula baby leaves to our sun-dried tomato, goat cheese, and pine nut mini pizzas! The kids don’t bat an eye-lash at the greens on their personalized pizzas because these taste so good!
Mature leaves can also be cooked or sautéed much like you would cook collards. With a TBSP of sherry, soy sauce, minced garlic, and vegetable oil + 1/2 tsp of salt and granulated sugar you can have a quick healthy side dish to accompany your sun-dried tomato mozzarella chicken. YUM!
If you don’t plan on eating a salad and just want to move it out of your system to put something else in, simply clean harvested leaves with water and pat dry with paper towels and spread out on a dehydrator. Dehydrate at 110ºF for 6 hrs until it breaks crisp (no moisture left in leaves.) Do not crush leaves, but place in a glass jar with an oxygen absorber and put in your spice and seasoning cabinet. When a recipe calls for pepper or if you’re making a soup, simply add in your dried arugula. BAM! (As Emeril would say…) or YUMMO! (As Rachel Ray would say…) You will get a hint of that pepper flavor as well as all the amazing nutrients that this little power-packed leaf holds.
Tip: After you dehydrate your arugula, don’t crush the leaves. Store the leaves as one piece as much as possible. When you “crush” or break up the leaves, it releases the flavonoids and other beneficial nutrients. We want those to stay in tack until we are ready to consume it in our cooking, so I always encourage folks to hold off crushing your leaves for this reason. This is also why you may notice your home-grown herbs and spices have so much more flavor than the crushed and processed ones from the grocery store.

Nutritional Benefits You’ll Get from Eating Arugula
So, we’ve covered how to use arugula. Let’s briefly touch on why you should be eating this green. According to the USDA, a half cup (approximately 10 grams) of raw arugula has about:
0.4 gram carbohydrates
0.3 gram protein
0.1 gram fat
0.2 gram fiber
10.9 micrograms vitamin K (14 percent DV)
237 international units vitamin A (5 percent DV)
1.5 milligrams vitamin C (2 percent DV)
9.7 micrograms folate (2 percent DV)
16 milligrams calcium (2 percent DV)
In addition, this leafy green contains some iron, magnesium, phosphorus, potassium and choline. It also is rich in phytonutrients offering 1,424 mg of Beto-Carotene B
Did you know that one cup of Arugula can meet over a quarter of the daily recommended value of Vitamin K? Vitamin K is essential to blood clot formation and bone formation. Some researchers even believe that vitamin K may be a key factor in bone development, more so than calcium. I want my children to have strong bones as they grow and I encourage them to eat salads daily. One way to help provide their bodies with what they need is to mix in some arugula into their daily salad.
Tip: If you’re having difficulty getting your children to eat greens, involve them in the growing process. Give them a garden that is completely their own area to tend and help them grow plants from seed. As they feel more connected to their food, their natural curiosity will kick-in and they will willingly try the food they have patiently waited for to grow.

How to Grow Arugula in a Hydroponic System
In this article, I’ll focus on growing it hydroponically, because that’s my preferred method of growing, but a lot of the same tips can be applied to growing in soil.
You can grow arugula in any hydroponic or aeroponic system. In a vertical garden growing system like the Tower Garden or Farm Stand, you’ll want to place this plant towards the top as you will most likely be harvesting from it continuously and keeping the plant size small.
Starting your arugula from seed: Choosing your arugula variety
If you’re growing in a hydroponic / aeroponic system, we strongly recommend you opt of seed that has already adapted to these growing conditions. Can seed from soil-grown parent plants grow hydroponically? Absolutely, but plants adapt epigenetically each growing season, so you’ll have a stronger healthier plant if you start out right with seed that has already adapted to the growing conditions you want to match. According to growers at the Seed Savers Exchange, seed DNA can hold 5+ years of growing seasons in which it can tap to survive and thrive. Choosing your seed stock source is more important than most realize.
Our arugula seed has been grown outdoors in the cool season of the Southeast in Zone 7 (not mentioning the zone here because it’s a perennial, but to help you get an idea of where the seed is grown so you can best match it to your own growing conditions.) GYHG Seed Co arugula seed can handle heat and humidity to a point before it bolts, but definitely plan on growing this during the cool season and start your seedlings 2 weeks before your last average frost date with the intention to move it outdoors as a transplant.
How many plants should you plant:
If you are wanting arugula on hand to pick fresh and mix into salads, I recommend planting four plants on a rotation (see below charts.) Place in upper level of Tower Garden or Farm Stand.
This is also a seed that you will want to plant on a continual basis on a four to five week cycle, so if you don’t have a Seed Starting Station set up already, you will want to read up about how to get one set up here. We recommend to plant four plants and keep them in your upper level of your Tower Garden or Farm Stand vertical garden growing system.

Outdoor planting in a hydroponics system: If planting in the spring, you will want to start your seeds indoors or in a greenhouse so that your seedling start will be about two to three weeks old by the time your last spring frost date rolls around. If planting in the fall, you’ll want to factor in your harvest date range and count backwards 4-6 weeks from your frost date.
Arugula likes to live around 45° to 65°F (10-18°C). Plant arugula so that it comes to harvest in cool weather. It may fail to germinate if it’s too warm. Use a UV light system of some sort to grow your seedlings indoors keeping the light source 8″-12″ if LEDs and 5″-6″ away from seedlings if fluorescent lighting.
How many seeds to plant per rock wool: We recommend planting about 3-5 seeds per rock wool cube. Arugula typically germinates within 4-8 days. Be sure to use seed that is packaged for the current growing season as it will aide your ability to germinate the seeds. You can always remove any excess seedlings down to two plants as the plants mature if you are concerned about crowding. Our philosophy is start out with more and thin down as needed (but don’t toss those microgreens you pull — they are healthy for you to eat as micro-greens).
How much nutrients you should give your seedlings: Keep rockwool moist to the touch but not drenched. When you see a sprout, you can add a tsp of kelp to your water and water the young seedlings while giving them bright light from a grow light.
Thinning out your seedling starts: As the seeds germinate and grow, you will want to pull (or also called “thin out”) the weaker seedlings from the rock wool. (Remember, this is not a wasted plant — you can simply enjoy eating it as a microgreen.) You will want to leave leave 1-2 plants per rock wool to grow to maturity.
Transplanting your seedlings into your hydroponic system: Seedlings should be ready to transplant to your Tower Garden or hydroponic system about 2–3 weeks after sprouting. Seedlings plants should be about 1-2 inches tall, with 3-4 true leaves, before they are ready to leave the nest and enter into the hydroponic / aeroponic Tower Garden or other related system.
Finally, remember that arugula plantings should be staggered in roughly 2-3 week intervals in order to ensure a continuous harvest. If doing a spring planting, your growing season will be longer than a fall planting. You can extend your fall outdoor planting season by adding a professional grade heater to your Tower Garden reservoir keeping water temps in the 50-65º F range for the root zone to continue to uptake nutrients — just be sure to cover your Tower Garden outside with a weather protection blanket like this when freeze warnings appear.
Nutrient levels for optimal growth throughout the growing season for arugula:
Nutrients: EC: 0.8 – 1.2 (We recommend Tower Tonic Mineral Blend™ for a well-balanced nutrient solution to feed your plants the proper N-K-P and micro-nutrients. You can purchase a 1 gallon set of Part A and Part B here.)
PPM: 560 – 840 (We recommend Tower Tonic Mineral Blend™ for a well-balanced nutrient solution to feed your plants the proper N-K-P and micro-nutrients. You can purchase a 1 gallon set of Part A and Part B here.)
pH: 5.5-6.2 (pH is essential to help the plant uptake nutrients.)
Light: (Amount of sun or light exposure throughout the day) Hydroponic arugula should get between 10 and 14 hours of light per day.
Arugula Temp Tips: (Root zone temp is essential to help the plant uptake nutrients)
Maximum Temp 75º Degrees Fahrenheit
Optimal Day CycleTemp 65º – 70º Fahrenheit
Optimal Night CycleTemp 60º – 65º Fahrenheit (Note: arugula can handle some frost so long as the root zone stays above 50ºF, so use a water heater in your reservoir if you want to try pushing the limits on it growing in the cold.)
Seed Storage 40º to 70º degrees Fahrenheit
Germination 60º to 75º degrees Fahrenheit
SOIL Growers: Note — Do not grow in soil with pole beans or strawberries. Good companion plants are bush beans, celery, carrots, nasturtium, mint, dill, lettuce, cucumbers, onions, rosemary, potatoes
HYDROPONIC Growers: See first chart on Cool Season Plants on this page for reference of what grows well at similar PPM ranges and pH ranges in a hydroponic / aeroponic system.
Harvesting your arugula:
Make a note of how many days to maturation on the variety of arugula you are planting and mark your calendar or in your gardening journal. When your plants have reached the baby leaf stage, take a sanitized clean pair of hand trimmers or scissors and cut the outer leaves of your arugula plant, leaving at minimum three center leaves to continue to grow. The plant will continue to produce leaves for you but will become spicier as the plant matures. If you don’t want spicier leaves, simply pull the mature plant at 5-6 weeks of age and replace the plant with a new transplant (see chart above). Ideally, your arugula should be eaten within a few hours of harvest; however, if storage is necessary, the correct conditions to prolong shelf life are rapid cooling down to 34°F (we accomplish this with an ice bath of water) and then spin the leaves dry and place between dry paper towels in a sealed lettuce container with and 95-98% percent humidity.
How to store arugula that is not consumed right away:
If you have more arugula producing faster than you can eat, there are a couple of options: dehydrating or freezing. To dehydrate your arugula leaves, place on a dehydrator rack at 110º F for 6-24 hours. When the leaves are crunchy (you can break them in half), remove from the dehydrator and place in a tightly sealed pouch or Mason jar with an oxygen absorber. Dehydrated arugula can be used in soups and ground into a powder to add to pestos, soups, or even on meats for additional nutrients.
You can also freeze your crop in an air-tight bag or container and use in smoothies or defrost and use in recipes that may call for herbs.
Let us know if you have any questions in the comments below and happy growing!
July is just around the corner and it’s time to start thinking about the fall garden if you can believe it! Here in the SE, we are blessed to have two growing seasons if the timing is planned right.
THINKING ABOUT WHAT YOU WILL PLANT FOR YOUR FALL CROP AND WHEN TO PLANT IT: All it takes to maximize your growing season is to know when your frost dates are for spring and fall. You’ll want to google what your last frost or freeze date is for your area. There is the traditional Farmer’s Almanac you can use, or I like Dave’s Garden’s resource as it gives a range of dates based on statistical data of when the first and last frost date has occurred. You’ll want to check this date each season prior to planning when to start your seed. I tend to lean on the 30-40% dates as my target date to plan off of and watch as the time gets closer. For our purposes, we will be looking at a freeze possibly happening between Oct 16-Oct 20, so I’ll split the difference and use Oct 18th as my first frost date and count back from this date based on the number of days (found on seed packet) for the plant will reach maturity and add in a 20 days for the plant to produce and bring a harvest in before a cold snap hits.
FINAL PLANTING OPPORTUNITY OF WARM SEASON PLANTS: If you are growing in the southeast (we are in Atlanta in planting zone 7B), plant the following vegetables no later than July 20th to allow time to mature before frost: tomatoes, okra, corn, pole beans, lima beans, cucumbers, squash and snap beans. If you have a sucker growing on one of your existing tomato plants, now is the time to start a new tomato plant which will continue to grow and fruit until hit with a freeze. Toward’s the end of July, start your final crop of snap beans as these can be planted by August 15 as seedlings into the garden for fall harvest.
Now is the time to also plant Zinnia seed. These heat loving annuals sprout in six days and bloom in a few weeks in the heat of the summer. Plant more Caladiums and Coleus as they’ll look better in the fall than the plants often started in May.
You can also plant another crop of Gladiolus for another flush of blooms for summer and into fall. Now is also a good time to divide Daffodils using caution not to cut into the bulbs as you dig into the ground.
AN EASY TASK TO LIMIT PESTS AND DISEASES: As you are harvesting your crops and cleaning off any dead leaves or removing leaves that have been attacked possibly by insect pressure, be sure to place these leaves in a 5 gallon tote to toss at the end of the day. You don’t want to leave dead leaves on the ground next to your growing plants as they will attract insects and promote disease which can transfer to your healthy growing plants. Keeping the ground around your plants tidy is a simple way to keep your plants thriving through the growing season.
CONTINUE TO FERTILIZE: For annuals, you’ll want to continue to fertilize at two-to-six-week intervals. When using granular products, make sure to water afterwards to encourage the nutrients to filter down to the root zone of your plants. For soil, you can use “organic” fertilizers like manure (cattle or chicken), blood meal, and/or fish emulsion. Dr. Tim Smalley, horticulture professor at the University of Georgia, has shown that composted hen litter continues to release food for four years after a 2-inch layer is worked into flower beds. Patio tomatoes (in a container) need to be fed consistently because constant watering rinses fertilizer out of the soil.
WATERING PLANTS: Be sure to keep tabs on watering soil-based plants. If you have had a good heavy rain, your watering tasks are probably eased for the day, but if it hasn’t rained, you’ll want to make sure you water deeply as needed to prevent drought stress. You can prevent root rot by watering deeply once per week and mixing plenty of organic amendments into the soil before planting and adding mulch to the soil surface beneath growing plants.
For plants growing in a hydroponic or aeroponic vertical gardening Tower Garden system, be sure to check your reservoirs at least twice a week as things warm up outside. If you’re growing tomatoes, tomatillos, eggplant, squash, kale, or beans, you’ll want to check your reservoir daily (or every other day) and top off the reservoir and add nutrients as these are “heavy feeders” meaning they take up a lot of nutrients when they are producing fruit, veggies, or legumes. Even though you are adding water to your system, it will be substantially less than the soil-based garden as hydroponic growing trials have been shown by NASA that these growing methods grow plants three times faster and produce 30% greater yields on average while using only 10% of the water a traditional soil-based garden would use to grow the same food.
INCREASE PLANT PRODUCTION: As your bush beans are growing, be sure to pick each day to encourage growth and plant output. Same is true with tomatoes… as they begin to ripen, pick often to encourage further fruit set.
PUMPKIN PLANTING TIME: Plant that big pumpkin for Halloween this month and give it plenty of room to sprawl. If you have a fisherman in your family, save a fish head and toss in to the hole before planting your pumpkin seedling into the ground.
JULY PLANTING CALENDAR: And finally, here is a quick cheat sheet you can print off and reference for what you can plant each week through either direct sowing (DS) into the ground or sowing indoors (SI).
But first, before we dive in… it’s important to know WHY we need to grow our own lettuce. So many consumers blindly are trusting the food system and don’t realize that our current mass-produced lettuce is picked before it’s prime, often travels many food miles to the consumer, and the lettuce food system has had 46 outbreaks nationally between the years of 2006-2019 (and most of those cases have happened in recent years!)
Dangers of Store-Bought Lettuce
Let’s first look at if organic lettuce can really be trusted… According to Consumer Reports, 72 percent of Americans try to avoid GMOs when they shop. And more than half seek out the “organic” label. But is organic lettuce really pesticide-free? Just because it’s organic, doesn’t mean it’s pesticide free… Despite being natural, spinosad, pyrethrin, azadirachtin, and other approved ingredients can still be harmful. (They are toxic pesticides, after all.) And in some cases, farmers must spray greater volumes of natural solutions because they aren’t as effective as their non-organic counterparts. In fact, up to 20 percent of organic lettuce may contain pesticide residue. And as though that weren’t enough, one study found that organic produce is more likely to play host to pathogens, such as E. coli and Salmonella. This is likely because it’s grown with organic fertilizers (e.g., manure and compost).
And that doesn’t even account for what is used as irrigation to grow the lettuce. Recent outbreaks were said to occur because of feed lots up stream tainting the irrigation supply. Hmmm….
Did you know that from 2006 to 2019, leafy greens like Romaine, Spinach and bags of Spring Mix from Salinas, CA and Phoenix, AZ accounted for at least 46 national outbreaks of E. coli. Check out this article and news report. (You may be more at risk of you’re purchasing a salad kit? The last outbreak sickened 11 people in Washington State. As of December 2019, there were two simutaneous outbreaks. “The FDA is investigating two other E. coli outbreaks, each caused by strains that are different from each other and different from the larger outbreak.” See report here.)
“Fresh-picked salad greens can have a higher nutritional value than store-bought greens. The flavor of homegrown salad greens is also noticeably better, as most kitchen gardeners will affirm. This is due to the extreme freshness of your salad, when you can use the instant “pick and plate” approach to preparation. Once you taste salad greens straight from the garden, you’ll be spoiled for life.
But arguably the greatest benefit is that of human health. In recent decades, there has been an increase in the percentage of foodborne illnesses related to produce, and greens have been one of the biggest culprits. This is mainly due to the soft leaves of the greens, which retain any germs they come in contact with. The CDC estimates that roughly 22 percent of all foodborne illness is caused by leafy greens. This has grown from less than one percent 40 years ago. This may be the best reason to grow your own leafy greens: while store-bought produce must be thoroughly washed to reduce the risk of illness, you can be sure that greens grown at home are much safer.” — Fix.com
The seriousness of these E. coli outbreaks have not only health impacts, but financial ones as well. According to Marler Clark, a law firm reprenting 28 victims from just one ecoli incident, said “Illness typically lasts from 1 to 12 days; however, E. coli patients who develop hemolytic uremic syndrome (HUS), a complication of E. coli infection, can remain hospitalized for months. They often require kidney dialysis and extensive supportive care. The cost of hospitalization for an E. coli case can range from several hundred dollars to tens or even hundreds of thousands of dollars.”
Store Bought Lettuce Food Miles and Nutritional Value
The other factor to consider is how far your lettuce has had to travel to get to your plate. Food miles are the distance food travels from where it is grown to where it is ultimately purchased or consumed by the end user. The term, “food miles” was originally penned from a study in Iowa that focused on how far food had to travel.In 2011, lettuce was grown on 206,000 acres in California (most coming from Salinas, CA), which represented 73% of the total U.S. acreage (Source: Lettuce_Production_CA). If trucks were to drive a straight line (which in reality they don’t — they make pit-stops at processing centers and go to distribution centers before traveling to our local grocery store), lettuce harvested in Salinas, CA must travel a minimum of 3,000 miles to Atlanta, GA and is at least 4-5 days old by the time it reaches our grocery store. It’s estimated that it take an average of 10 days to go from farm to our plate! Are you even getting any nutritional value from eating it at this point? We’ll explore that in a minute…
One thing to note, since the 2019 E Coli outbreaks, the lettuce industry has incorporated a standard of placing labels on packages of romaine to indicate where the lettuce originated from so that the CDC can better track down the source of contamination. (Yes, I’m trying to shake you out of denial — it’s really that bad.)
The other factor at play with store-bought lettuce is the depletion of nutrients from the time the lettuce is harvested to the time it reaches our plate. Like mentioned earlier, it takes upwards of 10 days from farm to plate in our traditional food system. Did you know that the nutritional value found in the plant actually starts to deteriorate within the first day or two of harvesting? University of California studies show that vegetables can lose 15 to 55 percent of vitamin C, for instance, within a week. And some spinach, for example, can lose 90 percent within the first 24 hours after harvest!
Here are our tips for growing lettuce with the hydroponic Tower Garden system.
Best Growing Conditions for Lettuce
Of the many varieties of leaf and head lettuce, most prefer full sun and temperatures between 45–80˚, making lettuce a good cool season crop. Lettuce can withstand light frosts. But in hot weather, it will easily bolt (i.e., quickly grow vertically, flower and produce seeds)—and this process typically makes lettuce bitter. So if you grow lettuce in warmer conditions, plant it in partial shade or grow heat-tolerant varieties, like these:
There are five distinct types of lettuce: Loose-Leaf (45-60 days), Cos or Romaine (~70 days), Crisphead (75+ days), French (50-75 days), and Butterhead (55-75 days). With a variety of colors, shapes and flavors available, plant several types of lettuce for tasty and interesting salads. Keep in mind, all varieties of lettuce grow very well indoors with grow lights.
If you want fresh lettuce every day for salads or other dishes, we suggest growing approximately 2-3 heads of lettuce per person. The cool thing about the Tower Garden system is you can grow in up to 28 ports (base Tower Garden with one extension) in less than a 2.5′ x 2.5′ space. That means in the corner of your kitchen or dining room or on your back deck, you can have instant access to your greens any time and harvest Tower to table within a matter if minutes — not hours — not days — MINUTES! This means you and your family will get optimal nutritional value from each plant because it is being harvested at it’s peak and consumed right away.
Seedlings should be ready to transplant to your Tower Garden 10–14 days after sprouting, or whenever they have at least 2–3 leaves and a visible root structure. When transplanting, keep in mind that lettuce is a good crop to plant near the top of your Tower Garden.
Once you’ve transplanted lettuce into your Tower Garden, keep the pH between 5.6-6.2 as this will help the plant uptake available nutrients in your water promoting growth. Using the Tower Garden Nutrient Solution, keep the PPM range between 560-840 or an EC of 0.8-1.2 for ideal continuous growth. Ten to twelve hours of light will be sufficient. Check the back of your seed packet for maturation as it varies by lettuce type and variety (typically between 30-85 days). Also, some lettuces can be cut and come again meaning if you cut about 2″ from the base of the plant, it will regrow new leaves and thereby extending your harvest.

Growing lettuce with Tower Garden decreases the chance of pests and plant diseases. But just in case, here are some potential problems:
Aphids are small insects that typically feed on young plant growth, causing it to appear puckered or deformed.
Cabbage loopers are green caterpillars that feed on the underside of lower leaves and in the center of the head of lettuce.
Cucumber beetles are yellow-orange beetles with black markings that sometimes feed on lettuce seedlings. Take care not to confuse these with ladybugs.
Botrytis, a gray-brown fuzzy growth, thrives in cool environments and can appear on plant debris that has fallen from the plant.
Downy mildew looks like fine white cotton or frosting and often infects lower plant leaves first. It can spread rapidly and kill plants in cool conditions.
Powdery mildew forms a white-gray powdery growth, usually on the upper surfaces of leaves. You’re most likely to see this common disease in late summer.
Tower Tip: Lettuce doesn’t typically suffer with aphids, especially if you’re interplanting basil at the same time (it is a deterrent to aphids.) Learn how you can naturally beat bad bugs and prevent plant diseases.
How to Harvest Lettuce
Since they grow so quickly, lettuces will be ready to harvest within a few weeks after planting. You can harvest lettuce in 2 ways:
Whole head. Remove the entire plant and net pot from your Tower Garden, or cut all the leaves off at the base of the plant. If you choose this method, be sure to have replacement seedlings ready.
Individual leaf. This technique keeps the plant alive and encourages continued production. When there are plenty of mature leaves present:
Harvest only a few leaves at a time, from the bottom of the plant upward.
Allow 2–3 leaves to remain so the plant may keep growing.
Repeat every 2–3 days until the plant bolts, or begins flowering.
After bolting, replace the plant with a fresh seedling.
We also have a handy resource that you can print off and cut down and slide into any sandwich-size Ziplock bag and use to store your seeds (limits oxygen and moisture which can be harmful to seed saving. We also print an extra sheet for our garden journal to keep records of how our crop performed so we can learn and remember what worked for the following year.
My father loved a well-manicured lawn (and still does) and we had an acre of it. (I jokingly called it a golf-course.) The dandelion was a weed to him and it was engrained in me from a young age that dandelion that had gone to seed were not to be blown for wishes. In my father’s defense, if we are to look at what a weed is, the definition states that “a wild plant growing where it is not wanted and in competition with cultivated plants.” So, in his situation, it wasn’t wanted in that space for his intended purpose. But if you grow it intentionally to use medicinally and for improving your health, we’ll then it wouldn’t be a weed, would it! In fact, I think the dandelion should return to it’s rightful status to be known as an herb — not a weed — and grown intentionally. Here’s why…
DANDELION GREENS ARE CHOCK-FULL OF NUTRIENTS
My mother shared with me recently that as she was growing up on the farm, my grandmother would go out in early spring and collect dandelion leaves to eat when fresh greens were scarce and the garden wasn’t producing yet. My grandmother was an expert in preparedness having lived through the Great Depression as a child and every year canned hundreds of fruits and veggies to use throughout the winter. The dandelion in spring was a source of vitamins A, C, K, and E, for her along with folate and small amounts of other B vitamins. The leaves also have a substantial amount of minerals, including iron, calcium, magnesium and potassium. Picking them in early spring as she did also meant the leaves would be smaller and less bitter.
DANDELION GREENS ARE RICH IN THE PREBIOTIC INULIN
Dandelion greens are also rich in a particular prebiotic fiber called inulin. David Perlmutter, M.D. who is an expert in the human microbiome, a board-certified neurologist, Fellow of the American College of Nutrition, America’s brain-health expert and #1 New York Times best-selling author has this to say about dandelions:
“Inulin, also found in foods like chicory root, Mexican yam, and Jerusalem artichoke, enhances the gut’s production of friendly bacteria like the bifidobacteria group. Boosting bifidobacteria has a number of benefits including helping to reduce the population of potentially damaging bacteria, enhancing bowel movements, and actually helping boost immune function. And new research demonstrates that higher levels of bifidobacteria may reduce colonic enzymes that may be involved in enhancing the carcinogenic effect of certain chemicals.” —David Perlmutter, M.D.
The dandelion belongs to one of the largest plant families — the sunflower. There are more than 20,000 species within this plant family, including daisies and thistles. Botanists consider dandelions to be herbs and typically use the leaves, stem, flower, and root of the dandelion for medicinal purposes.
Flückiger and Hanbury in Pharmacographia, say that the name was conferred by Wilhelm, a surgeon, who was so much impressed by the virtues of the plant that he likened it to Dens leonis. In the Ortus Sanitatis, 1485, under ‘Dens Leonis,’ there is a monograph of half a page (unaccompanied by any illustration) which concludes: ‘The Herb was much employed by Master Wilhelmus, a surgeon, who on account of its virtues, likened it to “eynem lewen zan, genannt zu latin Dens leonis” (a lion’s tooth, called in Latin Dens leonis).’ — Botanical.com
A DIURETIC FOR DEALING WITH EDEMA
The root of the dandelion can be dried and chopped up to make Dandelion Tea. It acts as a diuretic, helping those with edema. Diuretic, tonic and slightly aperient. It is a general stimulant to the system, but especially to the urinary organs, and is chiefly used in kidney and liver disorders. According to a 2009 study published in the Journal of Alternative and Complementary Medicine, participants showed a significant increase in frequency of urination after the first two doses of Dandelion tea. Water weight, and subsequent bloating went down. Cautionary Note: “Before you begin to use dandelion tea medicinally, you may want to discuss it with your doctor – especially if you’re pregnant or have an irritable bowel,” warns Dr. Manglani.
AIDS IN DIGESTION & HELPS TO COMBAT UTI’S (UNIARY TRACT INFECTIONS)
It can also aid stomach irritation and aid in digestion. “Dandelion tea can have many positive effects on your digestive system. It improves appetite and soothes digestive ailments,” says Dr. Ritika Samaddar, Head of Dietetics at the Max Super Speciality Hospital. “According to various studies, dandelions aid our digestive system by maintaining the proper flow of bile. Dandelion tea helps with mineral absorption and soothes the stomach lining,” says Dr. Manoj K. Ahuja, Fortis Hospitals.
LOWERS BLOOD SUGAR
Various studies have shown that dandelion tea lowers levels of blood sugar and can in turn treat diabetes. It removes excess sugar that is stored in the body due to its diuretic properties and helps in stimulating the production of insulin from the pancreas. It is a great way to fight diabetes naturally,” adds Dr. Manglani.
And lastly on the topic of dandelion tea… according to Dr. Sharma, dandelion tea contains anti-cancerous properties. A study conducted in 2011 by the Department of Chemistry and Biochemistry at the University of Windsor in Canada found that dandelion root tea was effective in killing different types of cancer as a result of its free radical-fighting abilities.
If you are growing your own dandelions for harvesting (recommended vs. risking a plant that may have been sprayed or encounter animal feces — I know, ewwwe), make sure your plant is two years old and the roots about 1/2″ thick. You’ll want to harvest around February/March when the the Inulin (a sort of sugar which replaces starch in many of the Dandelion family, Compositae) contains about 25 per cent insoluble Inulin. If growing for root production, I recommend planting in a loose soil rich in compost. Be sure to keep heads of dandelions trimmed so they don’t propagate and frustrate your neighbor’s lawn efforts.
SUPPORTS LIVER HEALTH & MAY HELP WOMEN WITH PCOS A study from 2010 showed that dandelion had a favorable affect choleretic (choleretics are substances that increase the volume of secretion of bile from the liver as well as the amount of solids secreted), anti rheumatic (agents used in the therapy of inflammatory arthritis, predominantly rheumatoid arthritis, but also idiopathic juvenile arthritis, psoriatic arthritis, ankylosing spondylitis and others) and diuretin (increased urination as a diarrhetic) properties. They examined the effects of dandelion consumption in rabbits and found that dandelion root and leaf could help lower cholesterol in animals on a high-cholesterol diet. Another study in mice found that dandelion consumption reduced total cholesterol and levels of fat in the liver. Mice that were on a high-fat-diet supplemented by dandelion leaf extract dramatically reduced hepatic lipid accumulation compared to mice only receiving a high-fat-diet alone.The researchers concluded that dandelion might one day help treat obesity-related nonalcoholic fatty liver disease affecting 15 percent to 55 percent of women with Polycystic Ovarian Syndrome (PCOS).
My hope is that this gives a little bit broader insight into the dandelion and I hope that you consider growing it as a green to add to your salads when the leaves are small and if you have the ability to keep up on the bloom cycles, grow it for two years and harvest the roots to make your own dandelion tea. There are also several brands that carry Dandelion Tea — check your local health food store. I like to fix mine with a little slice of ginger and a dash of local honey. I am getting to the point where I actually prefer it over coffee (gasp)!
Let me know what you think if you try growing it or try dandelion tea in the comments below!

New to growing your own food in a Tower Garden? First off, kudos on your decision to take control of your own health and it all starts at the foundational level of the food we put into our body. It actually can go even deeper than that… it all starts with the parent plant that made the seed that we collect and then grow and then harvest to put into our body. But I digress…
When considering what to put into your Tower Garden, there are certain vegetables and herbs that grow well together. I have grouped these plants based on shared PPM (parts per million) values. You will need a PPM meter to measure what your water’s PPM is with the nutrient solution added.
When determining our list below, we look for areas where PPM levels share common ground (see blue vertical bars to highlight overlapping plant PPMs)… Note: this PPM reference chart is available in full for all our Tower Garden and hydroponic clients, but here’s a little snippet:
Note that some plants can tolerate higher levels of nutrients than mentioned here as these are ideal ranges for growth. You’ll know when a plant is getting too high a level when the edges of the leaves get a brown tint (called tip burn). Otherwise, know that these plant groupings are going to grow together fairly well at certain PPMs and that you can push some of the plants that are below the PPM level to the next level up in some cases…
based on the PPM of 775 and a pH of around 6.0, you could grow these plants together using the Tower Tonic Minerals Formula Parts A&B: Arugula, Artichoke, Basil, Calendula (petals of flower are edible), Cilantro/Coriander, Dandelion (leaves edible & root used in tea), Fennel, Lavender, Lemon Balm, Menarda (Bee Balm), Mustard Greens, Nasturtiums (leaves & flower are edible + plant deters some insects), Oregano, Pansies (flower petals are edible), Parsley, Rosemary, Sage, Thyme, Violas(petals of flower are edible), Watercress.
based on the PPM of 1000 and a pH of around 6.0, you could grow these plants together using the Tower Tonic Minerals Formula Parts A&B Artichoke, Basil, Chives, Fennel, Kale, Leek, Lemon Balm, Menarda (Bee Balm), Mustard Greens, Oregano, Parsley, Peas, Rosemary, Sage, Thyme, Watercress
(Lettuce/Romaine may grow in this range as well, just watch for tip burn on the leaves — some varieties may tolerate the PPM level)
based on the PPM of 1265 and a pH of 6.0, you could grow these plants together using the Tower Tonic Minerals Formula Parts A&B: Artichoke, Beetroot, Bok Choy, Broad Bean (Fava Bean), Carnation (2′ tall, but petals of flower are edible), Cauliflower, Celery, Chives, Cucumber, Kale, Leek, Marjoram, Menarda (Bee Balm), Mustard Greens, Parsley, Peas, Purslane, Pumpkin, Spinach, Summer Squash, Strawberries and Swiss Chard, Turnip Greens, Water Cress, Watermelon, Zucchini
based on the PPM of 1490 and a pH of around 6.5, you could grow these plants together using the Tower Tonic Minerals Formula Parts A&B: Beans, Beetroot, Bok Choy, Broad Bean (Fava Bean), Celery, Eggplant, Endive/Chicory, Chives, Cucumber, Kale, Melon, Mint, Okra, Hot Peppers or Sweet Bell Peppers (Note: Planting both near each other may result in cross-pollination if outdoors and open-pollinated by bees and your sweet peppers can get a bit of heat in the flavor department. If growing indoors and hand pollinating blooms, you should be fine.), Purslane, Pumpkin, Spinach, Summer Squash, Strawberries, Swiss Chard, Tomatillo, Tomato, Turnip Greens, Watermelon, Zucchini
Remember to put larger plants like kale and those that vine like peas, cucumber, and nasturtiums towards the bottom and you’ll need a support next to the Tower Garden where the vines can continue to grow out and fruit. Taller plants go towards the top (like Celery and Rainbow Swiss Chard).
based on the PPM of 1990 and a pH of around 6.5, you could grow these plants together using the Tower Tonic Minerals Formula Parts A&B: Beans, Beetroot, Broccoli, Brussels Sprouts, Cabbage, Dill, Hot Peppers, Sweet Bell Peppers, Tomatillo, TomatoKeep in mind that your squashes, watermelons, tomatillos, and tomatoes are going to be heavy “feeders” meaning they will drink up water and nutrients during the hotter summer days.
Okay, so now you have an idea of what plants have similar growing PPM characteristics. Select one PPM group based on vegetables and herbs you like to use every day!
Keep in mind that for most of us, lettuce has to travel quite a ways if you’re purchasing it from a big box store especially. 70%+ of all romaine is grown in Salinas, California. That means that romaine has to travel roughly 3,000 miles to get to my plate here in Atlanta, Georgia. They say on average it takes 10 days for a harvested romaine to get from the farm to our dinner plate! This is unacceptable! Especially since we know from industry studies that due to respiration rates of plants, nutrient availability decreases within the first 24-48 hours! That translates into you losing out nutritionally on the very purpose of eating that salad! So, with that in mind, simply starting by growing greens is a great place to start. I also like greens because of they mature in 4-6 weeks meaning you get to see your success (and enjoy the fruit of your efforts) earlier rather than later.
The other thing to consider regarding a salad is the number of varieties you have probably never tried because the grocery store only carries 3-4 options. I have found that some of my best salads incorporate a variety of greens and textures. Have fun exploring greens you’ve never tried before — you might find you really like them fresh off of your Tower Garden. I had always shy’d away from Bok Choy in the grocery store because it looked limp and lifeless, but when I grew it in the Tower Garden it was super tasty and I learned that I could keep harvesting for 2 months until the plant flowered. Now it’s something I always plan on growing because it can be added to soups, quinoa, and salads.
If doing a greens selection to grow on your Tower Garden, I like to recommend my clients include a nasturtium on the lower part of their Tower Garden because a) you can eat both the leaves and the flower, b) most people have never tasted a nasturtium because they are not found readily in the grocery store and most often found on the fine diner’s plate, c) they are so pretty to look at on your tower and d) they are companion plants meaning they are good to grow next to other plants to help deter certain pests… When planted alongside cucumbers. eggplant, tomatoes, or squash plants, nasturtiums may repel cucumber beetles, whiteflies, aphids and squash bugs. There are other edible flowers in this range that would be fun to explore if you’re willing to be adventurous.
If you decide to do a vining crop with a higher PPM, keep in mind space (tip: put a trellis next to where the plant’s port is and it can grow off to the side. These vining plants are often water hogs and love the sun, so plan accordingly for anything planted above them — those plants will also need to be heat tolerant. I always recommend including a flowering plant as it will attract pollinators and pollinators (aka: bees) will plump up your fruit and leave your flowering plants in a better state than how they found it.
Tomatoes are the most popular thing to grow. Ideally, you’ll want to look for varieties that have compact traits, but if you do have room next to your outdoor Tower Garden, make sure you can handle the growth habit on a trellis. My favorite tomato is an heirloom variety, Cherokee Purple, and it’s vining can reach up to 10′ or more if it’s given the nutrients it loves. (And BOY do they taste AMAZING!!!!) Cherry Tomato varieties are going to be prolific, so plan a space to support their growing needs to you have airflow and are able to easily keep pests from moving in on your crop.
Tip: If you are putting large vining plants in the lower ports of your Tower Garden. Plant to the left, right and on the back side leaving the front port open. (You may want to cover that port with a rubber disc like this.) The reason for leaving the front port unplanted is you need access to your water reservoir opening and some vines take over and make it difficult to reach it.
And my last thing to highlight is the pepper — remember that if you are growing outdoors and have hot peppers and sweet peppers both growing in your Tower Garden, you may get some cross-pollination through open-pollination and your sweet peppers might be hotter than their parent plants. It’s a good idea to just pick either hot peppers or sweet peppers if growing outdoors. Now if you’re growing indoors under lights, you can plant both hot and sweet in the same system in ports on opposite side of the Tower Garden because you will have to self-pollinate your flower buds anyway (turn a fan on to give your tower a light breeze or hand-pollinate with a toothbrush or paintbrush).

I wanted this space here on Grow Your Health Gardening to be focused on how to grow food for the gardening novice, but today I wanted to pause and just reflect on something (or should I say someone) that is near and dear to my heart.
Last night, our family attended a beautiful catered banquet through our local County Extension Office Master Gardener Organization where our oldest son, Joshua, received his official Master Gardener Certificate and official name badge. He is the youngest Master Gardener in our county of 164,044 people (at the time of writing this post.) It was definitely a proud moment for me, his Mama, having watched him grow (pun intended) over the years in his passion and skills.
Of my five children, Joshua is the one that noticed me saving a seed every now and then. Soon, I was finding other seeds next to my collection and now he is a better seed saver than I am! He gets it. He understands that within that seed is life and the potential to keep giving life-giving food to others he loves.
I sometimes call him “Farmer Josh” out of love because he loves to play in the dirt and grow things. We come from a long line of wheat farmers. Joshua’s middle name is fitting, because he is actually named after his Great Grandfather who was a dry land wheat farmer. (Growing wheat definitely isn’t Joshua’s future because we learned he was allergic to wheat dust one year while helping out with the harvest.) Every summer, my family would help bring in the wheat harvest. My grandmother had a large garden and instilled in me from a young age the value of a garden. My parents continued to teach me through growing our own family garden for years and then the busyness of life demanded the need for convenience over preparedness and the garden fell to the wayside and eventually our plot of dirt became grass and then a garage was built over the location.
When my twins were three years old, my husband got a consulting job in the Southeast, and we moved 3,000 miles across country to Atlanta, Georgia. Our soil profile changed from grey-ash-like soil to red dirt full of clay. I would put rich compost down into my garden beds only to find them return to hard clay by fall. My growing mojo had come to a screeching halt. (I would later learn what to do to re-build the soil profile thanks to new friends made in Georgia and other Master Gardeners.)
Feeling discouraged, I kept thinking there had to be a better way. That’s when I stumbled across a video of a guy on YouTube who was growing tomatoes hydroponically in Bato Buckets. I was fascinated by his methodology and soon I was pouring myself into any resource I could find about how to grow food hydroponically. It was also about this time, that my oldest two sons were studying the difference between human cells and plant cell structures. Since we were homeschooling, I decided to dive deeper into teaching them more about plant biology (botany) and together we were going to learn about hydroponics and how to grow food. My husband helped me guide the boys in building a Bato Bucket system like the one I saw on YouTube and I went down to my local nursery and bought 10 different tomato plants and we transplanted them into our new system. The boys would monitor the pH level and nutrient level of the plants and write down observations. It was a lab of sorts for us to learn from and boy did we learn!
The following year, my husband had a heart attack. It was then that I realized we were not doing enough about eating wholesome vegetables. In my research the previous years, I had narrowed my next hydroponic system to two options. But when our need became more urgent, I knew I didn’t want a DIY system — I needed something out of the box that would just work. (My last DIY system cost as much as the one out of the box.) He agreed to getting three Tower Gardens by JuicePlus+. Here was our first year’s crop (pictured below).
I was amazed at how easy it was to fit it into my busy lifestyle. No weeding. No effort to build up soil. No nematodes to eat my crop. No irrigation system to monitor or standing there day in and day out to water plants for a half hour while our water bill took a hit. I would just watch the reservoir every week and check pH and nutrients — it was right up my alley. I needed low-maintanence gardening. Joshua dove in with me and helped monitor the growing system as well.
I also learned of our local Master Gardener program through our Extension Office that shared space with 4H. I took the kids to any free program they had to offer on growing things or even one was on bee keeping. In fact, Joshua won the door prize at one of these meetings and he and my youngest son walked away with some free plants! It was around this time (I think Joshua’s Junior year) that I turned to him and planted the seed-thought of him becoming a Master Gardener. He had the time now to make that happen and then could use the skills he learned for the rest of his life instead of waiting to the end of his life when he retired to enjoy it. He was excited by the thought of that idea and inquired only to find that you had to be 18. He wouldn’t be able to do it as his senior year project. But he didn’t give up on the goal. He applied for the Master Gardener program that was to begin around the time of his 18th birthday.
What probably many don’t know is that during this time, our family went through a difficult time. My mother, who lived 3,000 miles away, needed help getting through a situation she found herself in and I had to leave for several weeks to help her. This unfortunately coincided with Joshua starting his Master Gardener training. He took an Uber each day and paid $20 out of his own pocket to get to his classes until other arrangements could be made on his behalf.
One of the great things that I love about the Master Gardener program is the wisdom of those who are involved. I’ve tried to teach my children to reach out to those with grey hair as they are a library of untapped resources. Joshua was blessed to have these amazing individuals come along side him and help him. They loved him because with his youth brought much needed muscles! lol I really wish there could be more young people involved because they are missing out on such a great resource. I want to see what can be done to bring these two groups of people together.
Joshua juggled working his required 50-hours of volunteer hours around with working a job. I saw him increasingly frustrated when he would miss a Master Gardener meeting (often held during the day) because he had to work. But it showed me what he truly enjoyed. Thankfully, he came to realization himself and asked if he could work for me and help me instead of continue in the electrical program he was pursuing. I really needed his help knowing that my own goals included the possibility of growing our crops to the point where we could take it to the local farmer’s market to sell. So here we are today, working on our upcoming growing season and it is such a joy to work alongside my son. He’s smart and helps things get done when I don’t have the bandwidth to get to it. Currently, he’s helping me clear some land to do an herb garden installation. He is put in charge of his younger siblings who help him clear out ivy that has overrun the space we plan to utilize. He also is good at cleaning out Tower Gardens and sanitizing them (as well as our cutting tools). We hope to also propagate some of the beautiful resources on our property to sell at the upcoming Master Gardener event this spring. And his favorite thing to grow indoors — orchids!
So, last night’s award dinner was truly special and I felt so proud of him for pursuing what he loved. And I feel so blessed to be his Mama and thankful that we have something in common to share over the years. I am praying for Joshua and that the Lord will continue to direct his steps as one day he will have his own family to provide for (and possibly me in my old age, Lord willing!)
Thanks for letting me share from my heart. And if I can encourage any of you with children… learn together! You don’t have to have all the answers or be an expert to be qualified to teach a child. It’s through the process of learning together about something that your children will come to understand that anything is possible to learn about if you just pursue it.
Happy Growing —
PS: If you ever read this post, Joshua, know that I am proud of you and can’t wait to see what you do next! Never stop dreaming and learning! Love you, Mom
