The flu is probably 5 ft. from where i want to put room, and the dryer vent probably 15ft.
I think 600W would be fine in a 4x4x7 room as long as you have a blower fan providing sufficient ventilation, as well as a good 12 inches distance from the reflector to the tops of the plants. With a smaller light like 400W I think you can get away with 6-12 inches but it might burn them a little with the 600W.
I doubt that it really matters which you choose to be your vent but I might go with the dryer vent because it is farther away from your growspace. I like the idea of displacing some of the noise associated with fans.
