Totally cool set up! i have a 1kw light that will totally fry up a 15 x20 room in a few hours. I set up an inline fan from the light to the bedroom window and it COMPLETELY solved my heat problem. Wouldn't have been able to continue growing if it hadn't worked--as it was we had central AC going in the middle of summer AND a window ac in the same room and barely kept the heat contained. The inline fan works excellently and I don't need any extra cooling etc for the room with it. Try one if you can.
