Im moving into my own place in about 2 weeks so im trying to get it setup now so i can start growing the day im in. Anyways my question is, my closet is 3 ft by 2.5 feet by 7 ft. and i plan on having a 600 watt light, so what size fan should i get? 4 in. fans from HTG move like 400+ CFM which seems like too much for such a small closet but idk how much heat a 600 watter will generate. anyone?
