Hey GC.. So i have 9 plants in different stages of life.. and I need to know how to properly vent my grow tent.. I have a 32x32x62 grow tent with a 4" inline fan pulling the air out of the 600w HPS light and into the carbon filter exhausting outside the tent. I have a 4" ducting running from the air conditioner vent into the grow tent but my temps are still at 85-87 degrees? (with the grow tent half open) What should I do to fix the temp problems? Also, what's the humidity level supposed to be at?
