Am totally confused about how to set up my ventilation system My closet is 4'W x 3'D x 6'H I got a 4"inline fan kit + carbon scrubber. Need to connect this to my cooltube light.Ideally exhaust out the top right corner and intake(passive) from the bottom left via several large pvc elbows. Where the heck should everything be connected to and from? Any help greatly appreciated brother stoners.
