Right now, I just am pushing the air into the attic and it's being sucked out of the room by an open circuit... no closed circuit at all. The air is then replaced from outside the room and a small amount from the hole in the flooring.

If the 600 watt is in a straight line as my other lights, then alls I need is duct connected to that hole in the flooring, correct?

I was under the impression you needed to not only suck air from outside, but also need to suck air out of the room. Can anyone elaborate a bit more?
razzapiggy Reviewed by razzapiggy on . Question about intake? Got a few cycles under my belt, but I am for the first time running into some temperature problems. Right now it's 81 in the room, trying to keep things down. As of now I only have an open circuit that is taking warm air out of the room, through the lights, and into the attic via my Vortex fan. There is also a hole in the floor that would be perfect for pulling cold air in... is this the passive intake? In a nut shell I am proposing that I attach some ducting to the whole in the floor Rating: 5
