i have a grow room thats 5 x 4 x 6.6, 600W hps/mh and mylar walls. I need to put in a exhaust and intake tube some how but i dont know how to make them. I was looking at Home depot and fans that have 70cfm cost around $30 each, would a 70cfm fan be good for a grow room this size? also would it be be better to use the tubes for dryers or straight metal tubes? should i duct tape the fans to the tubes and thats it? ventilation system complete? any help would be greatly appreciated
