O and i have a quick question for all you pros - I am using a 3'x3' mylar grow tent About 6 1/2 feet tall and my ventilation setup is a 100cfm fan with a carbon filter so the actual suction is less than that - if i were to go and get a 400w HPS light for flower (one i was thinking about picking up http://www.amazon.com/Sun-System-2-4...2575602&sr=8-1) what should I use for ventilation to keep this cool - is the 100 cfm good? If not what should i get?
