hey guys i was thinking of getting this inline fan and filter http://www.amazon.com/Hydroponics-Inline-Scrubber-Carbon-Filter/dp/B004Q2ER5C/ref=sr_1_5?s=hi&ie=UTF8&qid=1365149650&sr=1-5&keywords=4+inch+inline+fan
my grow box is gonna be 3ft wide by 2ft long and 4ft high gonna be growing 2 Autos and needed to know if this would be a good fan or is it too much for a small box ... or should i go with this cheaper fan http://www.amazon.com/LEDwholesalers-Inline-Booster-Inches-GYO2405/dp/B0069GE9N8/ref=sr_1_1?s=hi&ie=UTF8&qid=1365149953&sr=1-1&keywords=4+inch+inline+fan
the CFM is lower on the cheaper fan any advice ?
