Is pH important in hydroponics?

PH control in VERY important when growing with any type of media (hydroponics or soil). The pH is specific to the type of plant you are growing. 7.0 is generally considered on the basic side and 5.0 is considered acidic. The pH directly effect how efficiently plants can uptake nutrients. Here’s a pH scale for growing: Acidic solutions have a pH between 1 and 6.9 (indoor tomatoes like 5.5-6.5) Alkaline solutions have a pH between 7.1 and 14. Neutral solutions are neither acidic nor alkaline so their pH is 7
