: I have a 11 plant system. What is the best pump time on and off. I am running 30 minutes on and off.
It depends upon what kind of system you use. Ebb and flow systems have to turn off the pump so the roots get some air.
My aero/hydro runs the pump when the lights are on, 16 hrs/day. The roots are suspended in the air and get plenty of oxygen.
