It's a DWC inside of a Rubbermaid with an exhaust fan on top, a computer fan blowing air parallel to the CFL's and a passive intake at the bottom bringing air in. I also today just added another pump to my set up to get more air bubbles. But lemme ask yall something, I saw something about the wick idea with the t-shirt, do i submerge like 1/2" of the net pot or do I just let the bubbles and mist sprinkle the wick to let it get up to the peat pod it's sitting on?
