LF - It's much cheaper to cool a small space than a large space. If you contain your grow in an enclosed area that is just the size you need for the grow, it will be cheap to cool. Personally, I think you should be looking at your closets and figuring out if any are suitable for a good grow op. It would be ideal for temp regulation if you could insulate the closet, but, even if you can't, small a/c units start at around US$100 and go up gradually from there. You don't have to worry about the power company turning the small a/c off, and you are cooling only the area you need for growing.

Whatever you decide, good luck! :thumbsup:
