Yeah, I've thought of the heat issue. I live in the south, so everything is hot here. Ive done some research on the thermal imageing. From what I've found, Its seems that they only use that when the think someone is growing. Just like checking the elec meter. And the way my roof is done, My ceiling will be kinda dropped below the roof line. I'd have to post a picture of it for you to understand, I just don't know how to on here. I allready plan on beefing up of the floor system. I allready have a set of stairs to the room, so I won't have to beef up my muscles too much. The room will be climent controled, so I think it will be ok, I hope. Guess I will find out the hard way. Thanks for the advice
