ideal hydroponic plant ranges chart

There has been extensive research done through university horticultural programs and grower-shared experience to identify ideal PPM ranges that allow each plant to thrive. Below we have grouped plants that grow together in ideal common ranges. Note that some plants can tolerate lower or higher PPM ranges than otherwise noted, but you may see the affects of being outside of ideal ranges affect the growth and health of the plant and any output levels. Keep in mind that plants can grow up to 30% faster in hydroponic environments because they are getting ideal nutrients that help them thrive.

We recommend the following pH and PPM meters (we have used all of these before):
• pH Meter: https://amzn.to/2ZKymvP
• PPM/TDS Meter: https://amzn.to/2WbFqRp
• Combo 5-in-1 pH and PPM Meter (we currently use this one): https://amzn.to/3e9WwVL
