165 cfm active air inline fan, 4in flex duct ran to hood(used 6in reducers on the hood so the 4in duct would fit) and then into an elf carbon filter.

So the fan sucks air through the filter, then through the hood, then out the cab?

Cool, what size inline fan you use? I don't wanna spend a lot of money on one, but not sure if a computer fan is sufficient enough...and I'm not sure how i would wire it to get power to make it spin.

i tried the pc fan thing.. and it can work. but i had to use 4 of them to keep my light cool.. and they were LOUD. save your money and get a good fan. i am speaking from experience. http://www.hydroponics.net/i/133756 here is the fan im using

looks like i can save about 40 bucks if i get that fan that ilovewest posted with a 4 inch charcoal filter. Will prolly go that route, less CFM's but less money too.

i got a special place in my heart for people from the mid west, lived there for a grip of years. fucking madison and minneapolis. good times. any way, http://www.plantlightinghydroponics.com/ has the cheapest equipment, go with them. but why im posting is this: i dont know if would work, but i have been thinking about this for cab growing. would a duct booster work as your primary fan, and could it hold the load? cuz they are like $40 for a 500cfm fan. like this. free air cfm:160 $39.90, 6inch http://www.plantlightinghydroponics.com/suncourt-inch-inline-booster-fan-wpowercordp-1021.html
also from my limited experiance you want to over shoot your fan, so if your getting the inline fan, why not shell out $10 and get the next size up, which has 3 times the cfm of the one your looking at. you can get a conrtoller for the fans speed, making it so you can run that fan at half speed, still get more air moved per minute, and have less noise. just trying to help.

those duct fans didnt do well for me. they do great untill you put duct on them. and they really dont work well with a carbon filter.
