LOL thanks that would have been an expensive mistake. yeah i was just thinking i could duct through to the next closet in my "office" so the light intake is separate from the room and get another vortex just for venting the room. What i have now is a gap under the door 2" high and 24" long so its pleanty of area for the fan, and i also have 4 3" abs vents in the platform i put in there. having been in there with the door shut there is alot of air moving. but i think separating the light and room exhaust is the best idea, i already have a speed control for the vortex so i could use that to control temps when it starts getting cold. thanks again stinky, you really know your stuff and i thank you for all your help so far.
