This is a very recent Do-it-urself. http://boards.cannabis.com/basic-gro...-air-vent.html U would have to probably cut a whole in ur door at the bottom and mount the "light baffle" there for intake.

Then u could bore a hole out of the door higher up, where most of the hot air is and set up a fan blowing out if that hole. U will want to put a elbow shaped PVC piece the diameter of the whole, paint the inside flat blach, and mount that on the outside of the whole to block out light.

If all of that is to expensive, simply impractical for u, ie - dont want to chop up your door, then i sudgest u get a very dark and thick blanket, prefferably black, and tack it up over ur window. That with the closed blinds should keep the light in and not out. Then u should be able to just keep ur gro clset cracked and set up a couple fans :thumbsup:
