Just remember the cfm of the fan must be less than the rating on the can filter.

I run mine the same way.

why must it be less? i thought it would have to be more. can you explain?

Your fan can't be too powerful or the charcoal won't filter well. This should not be a problem. Using a 400w HPS in a cooltube, a can33, and a 200cfm inline centrifugal fan will do the trick nicely. Eliminate the heat and the smell. I would not use the air input fan as it will reduce the neg air pressure in the cabinent and possibly cause odor problems. A good fan pulling air out of the cab and running through the cooltube is key. The Suncourt TF104 is good for around $125. It only draws 40 watts, is 200cfm, and made to run 24/7

ima going to use a 600 watt after friday my room is 3 feet by 8 feet and 6 feet tall what filter and inline fan should i use? give me links.

you should be able to see that all i did was make two big ass holes the size of my ducting in the wall, one for intake the other for exhaust. I put a V aluminum pipe on the AC vent capped one side(removeable) and the other side if for the intake to the grow room

this cheap inline fans only really put out about half of its rated cfm with ducting n shit.. so if that one is 4 inches, its rated cfm is like 80 , which is not near enough in the first place for ur cubic feet of ur room , and really, its only like 40 cfm if u have ducting n shit hooked up.. so ur way off. Ur cubic feet of ur room is like 144 , cfm is cubic feet per minute (of air moved). That should give u some idea of what strength of fan to get. Prolly something like this ( http://www.canadianwholesalehydroponics.com/products.cfm?p_id=109&show_details=1&catpage=2 ) at least, or a cheaper thing would be a blower like this (http://www.canadianwholesalehydroponics.com/products.cfm?p_id=89&show_details=1&catpage=2 )

Its always best to get a little stronger fan than u really need, because u have to compensate for ducting, and other things that will obstruct the air flow

ok im thinking of gettin a 176 cfm inline fan 4 inch and a Max Airflow: 150-265cfm carbon filter. will that work?

here are some pics, more on other thread. day 25

here you go
first pic is CB, second is VK, and last is LA
