If you are looking for a rubbermaid in action, you can check out my current grow log(link in my sig). I would not do the 2 fan system, 1 for exhaust is fine as long as its a fan of good quality. Also I personally don't think you could fit more than 1 plant at a time in the box unless you are running a sog/scrog style with multiple clones. FWIW Bodom was also only running a single plant in his(hers?) rubbermaid aswell. Good luck:jointsmile:
