I exhaust my room partially right THROUGH my air-cooled lights. The light vent intake is inside the grow area and exhausts to outdoors. With a burly enough fan, that's an option for you if you have a decent passive intake somewhere in the room.
stinkyattic Reviewed by stinkyattic on . Is 4" vent big enough? In a 10' x 10' area, I have opened up my vent line and now have four inch open vents on oposite corners of the room. Does anyone think that this is good enough venting or should I open the vent up to 6"? SCIENTIXT Rating: 5
