Im tryin to build a little grow op. Im tryin to veg 1 mother plant and 2 clone in rockwool under t5's using drip method. And also tryin to flower 2 plants in hydroton under 250watt hps using ebb and flow method . The problem i have is have long do i set the pumps to run for on each setup?
You're basically talking about the difference between hydroton and rockwool. Rockwool holds water much longer than hydroton. With hydroton in e/f, I think 15 min every 4 hrs is best. In rockwool, MAYBE twice a day.
