Ok so I am thinking of using cooltube for 1000W HPS like a 200-300 cfm fan with maybe 4 feet of strait ducting... so if i were to do this what kind of exhaust fan should I have for the room 4ftx5ftx6ft? Like do I need the 3 times the volume of the box exhausted per minute even though I have the cool tube?
