i have a 2’x2’x48” veg tent with a 400w mh and a 3’x3’x8’ flower tent. I have separate ventilation on them now. I have a 290cfm fan on veg venting back into the room and in taking cooler air at the bottom. The flower tent has a 390cfm fan exhausting into attic and a stand alone a/c unit that vents into attic. My question is can i vent the veg tent into the top of the flower tent and then the flower tent would exhaust them both? Anybody
