if you look at my grow... that is my box. thats where I got my setup from.http://420tribune.com/2010/03/diy-stealth-grow-box/This design looks very professional. I can only make one about 28 inches high so I'll have to get tupperware containers no more than a little bit taller than a foot. The key to growing inside a box like that is probably exhaust ventilation. Making neat sealed holes with piping and the fan as opposed to cutting into the rubbermaid with a knife probably improves air flow.
