Hi, I have a grow tent on its side due to space constraints. It gives me about 3 sqft and has about 3 feet of height total. I have done ebb and flow to the point of too much and eventually rotting the main stems. It was in rockwool and with hindsight I think twice a day at most would have been sufficient not the 4x I did it. So now I am trying once again with White Rhino seeds, hydroponically, in rockwoll but am considering the little 1/2 gph valves on the 1/8 tubing, 6 of them, one for each plant. The big question of course is how much and for how long do I turn the pump(s) on?
