Hi,
Well thanks for to your help I know have a much better understanding of Ebb and Flow.
I will be using this system for my next grow.
I was thinking of filling the tray with grow rocks, I am wondering how efficent this meduim is?
Also would there be any addvatage to leaving a 2" rez of water in the bottom of the tray (Maybe adding some air stones for extra airation) or would this just be pointless?
How often would I water a meduim like this?
Would it be worth covering the top of the tray with some sort of light/water proof sheet.
