I go from EZ CLoner staright to Hydroton in 5 inch round netpots. I bought the lid to the Turbogarden so the pots would be suspended above the flood pan a little bit. The rockwool will hold extra water and will not be able to be watered as often. I may end up using rockwool at some point, but I am trying to do it without it. Everyone seems to have their own way. The Homebox works great for me, I hope we can all learn from each other. If you have planned it will take $1400, then take $2500 to the grow store with you. Definitely Dont forget good meters. What type of fertilizer are you planning on using?
