4x4x6'6" grow tent
Directly behind it is a basement window that I boarded shut with plywood and sealed it. (the window is gone).
I have the exhaust flange on the bottom right side of the board, and the intake flange on the top left side. I connected the fan to the board via the flange and connected my foil ducting to it which goes into the top of my tent and down.
I had the other side hooked to my glassed reflector, but it didnt seem to be doing much for the room temp so I unhooked it. Instantly the sides of my tent started to suck in.
So I know its exhausting well, but it doesnt seem to be pulling any intake air in from the other foil ducting. I figured the negative pressure would cause the intake ducting to draw fresh air in from outside. If it is, its barely doing it.
Should I put the fan INSIDE the grow tent? I could probably rig it up if I needed to that way.
I have a 600w glassed lensed reflector. It has a duct flange on the very top and one opposite the side of the bulb. Should I exhaust the air from the light itself? Or just from the room in general? It seems to work better when its just hanging into the room to me.
