I want this fan because i don't want to wait longer and save up but i don't feel like saving up for a really long time. I really want this fan Amazon.com: LEDwholesalers GYO2402 6-Inch 240 CFM Air Duct Inline Hydroponic Booster Fan: Patio, Lawn & Garden to cool my light, but i don't now if that is enough. Also don't i need three fans for : bringing air in, taking it out, and to cool my 600 watt. My second choice is Amazon.com: Hydrofarm Active Air 6 inch In-Line Fan 400 CFM: Home & Kitchen. Will i need three of these? And is 400 cfm too much for my (2'7x4'11x6'7) tent, especially if there is three of them. Also do Thoses hydro farm inlines last a long time or do they die out in a year or so. So what would you guys do in this situation.
usally 6'' fans run around 435 CFM. and thats what i need to cool my 600w, but its alot more. so if you could get 2 on the same vent line then that would be good. my grow tent is 4x4x6'6....so its similiar. i would go with the 400 cfm. no idea if they die in a year... i use the bigger enclosed ones.
