Vent and Fan Information.

i have a 4 by 4 by 7 foot tent with a 3 foot by 3 foot ebb adn flow tray with 2 mh 400 watt cooltube lights that are 8 inch. i have 2 reducers to reduce the end of the lights to 6 inch. my 12 inch carbon filter is set up to recieve a 6 inch hose. what inline fan would i need to cool the light and still use the carbon filter? please help guys. i have posted a few other threads with no replys. am i doing something that is pissing anyone off. i just want to get going with my grow i have a ton of pics on my camera with most of me grow gear. just dont know how to put them on here.

hey Southern. do you have a local store you can go into, take them the model # or mfg name of the tent and get them to help you? the kind of inline fan would be centrifugal fans: http://www.grownhydro.com/ventilation-c-31.html - these are probably more than you need, but if you search you can find a 3" or maybe 4" fan. You attach the smaller tube side of the filter to the intake side of the fan. I think something like this would suit you perhaps :

hopefully that helps. let me know if you have more questions.
