OK I built one of those Rubbermaid stealth boxes. I used two 32 gallon boxes It has done me justice, but now i want to convert to a hydroponic system. I was going to convert the bottom half of the box into a DWC container but that wouldn't leave me with much space to grow vertically. So then i though maybe i can get a smaller container to fit in the box. figures i could use something that held 4 - 3" net pots but got confused on how big the container should be. Does anyone have any ideas on the conversion or should i scrap the idea all together.
