It was out in the open for a while, i have to say the mylar is really just emergency blankets. With the CFLs it works in a basement, because the outside temp of the metal cab is about 50-60, and the inside is 84ish, I try to go there as much as possible and keep the air flow going. I'm thinking of putting a computer fan, although my friend works at a HVAC/plumbing, you think i should take that route, i'm pretty sure he could get me a good price on any fans for that kind of stuff. You think that's necessary or should one or two 120mm fans do it?
