    Special air-cooled venting

    Sooo... I got an air cooled hood and a tent for flowering. Cool... But... The air cooled hood plus the 6" duct fan comes out to 30" in width. Not bad, but it exceeded my expectations by about 4" This leaves me with an inch on each side with the new tent. That being said, with a 32"x32" tent...

    extractor for active cooled cobs + pico ez mate in EU

    Hi guys, I know these leds would generate less heat than hps, but If I would run 15 of vero 29s v7s each at 50w 1400mah with active fans (arctic on each cob) should I connect the extractor on the top of the tent? or would be better in the middle . Most important question that I have is how big...
