I have 4 seedlings in a closet approximately 2âŒ4âœ–8 foot tall. I can't cut holes into the door or wall and with the door shut it gets way to hot on there even though I'm using cfls. So I have to leave the door open all the time, but I would like to be able to shut and lock the door when I'm not home. Would putting a small fan in there do any good or just blow hot air around? Other than cutting holes in the door/walls any suggestions to help lower the temp. And add some ventilation?
