Thanks.

I will read more on fans and circulation.
I am concerned about inside temperature.
blink_inc Reviewed by blink_inc on . SOG Grow box - My first time and I need help Hi all, I am looking for suggestions. I have read so many posts I don't know what direction to take. I am working with a crawl space that is only 48" high. I want to make a 4'w x 8'l x 4'd box out of plywood and 2x4's. The inside will be styrofoamed and all corners sprayfoamed followed by white plastic or mylar with 6" pots to grow SOG (I think). Computer fans for ventilation and a carbon scrubber for odour.
