I have a 150w HPS on 1 plant in a 4' wide x 3' deep x 7' high and my the temp goes from 78 F - 90 F. I have a small fan in there but I can't cut anyholes for ventalation b/c I rent. What main question is, is there any way to set up some type of ventalation system without cutting anything? And what is the hottest my room can get? Any help appreciated, thanks
