Cool! But how much heat we talking here? Im curious for my own benefit. I've thought of buying twin 150's ( i can get em cheap) but have stayed away from em cause of heat concerns. I figure twin lights would be better for me cause my grow area is a long rectangle, not square.

My grow box is roughly 24 sq/f.

Would one 400w or two 150w be too much if vented properly?
