Iam using a 400 watt hps/MH in a cooltube. I will bring outdoor air into my cooltube and vent the exhaust air into my attic.
The wall Iam getting the outdoor air from is about 9 feet away from my cooltube. So how strong of a fan would I need? 170cfm? 250cfm? |

The 6" might work. I know the 4"" inline sucks ass. those inline fans are made to boost air flow. If you can find a 4" squirrel cage fan. a bit more money, but alot more air. I found a old used bath fan that pushes air very well. the cage type fan just does a beter job then the wing fans.
