Need Exhaust In 5x5 Closet

i was thinking to get this from wallyworld!
http://www.walmart.com/ip/Middle-Atlantic-SR-Series-115-VAC-4-1-2-Cord-and-Hardware-Included/11962383
but open for ideas chuz i need my room to be "Cooo"
already have an inline fan bringing air out
and running a 400W HPS

depends on how much light you gonna run but odds are that is not enough, inline fan is what your looking for and your not getting it from wallyworld.

i have a inline fan to bring air out and im running a 400w
im tryna close the door but it gets to 86F wen i check on it so i have to leave it open

or one of those CFM ceiling fans for bathrooms because their quiet but i would have it at the bottom near the floor instead of the ceiling so dont kno if it would work that way

400w not sufficient to flower a 5x5, i'd add light or shrink room to 3x3 max. you need a cfm that exchanges your cubic feet volume 2-3x

thats not helping my question..

Don't bother with computer fans. If you arn't going with a legit inline fan get an inline duct booster fan. You don't need to go buy a transformer to run this (just strip a .99 cent extension cord) and they move a bit more air and area easier to hook to ducting...

Home depot has em for $14

i already have one moving air out so jsu have one moving air in?

If you have one moving air out then air is moving in already as well - not like you can just suck all the air out of a closet. What are your temps at now in the enclosure and outside of it?

I used inline duct booster and a pc fan like that for my closet awhile back and it didnt do enough for the temp plus way 2 noisy. I switched to a bath fan instead of booster. I think this is the one i used...worked way better. http://www.homedepot.ca/webapp/wcs/stores/servlet/CatalogSearchResultView?D=945396&Ntt=945396&catalogId=10051&langId=-15&storeId=10051&Dx=mode+matchallpartial&Ntx=mode+matchall&N=0&Ntk=P_PartNumber#BVRRWidgetID

That thing looks light it would be over kill in a closet. I have a sliding door closet so I take a box fan and place it in the door.

how would it be an overkill when the 4 inch in-line has 80 CFM
and a bath exhaust does too http://www.walmart.com/ip/Premium-Builder-Flush-Mount-Ceiling-Fan/11372578

Used several of those as well. Again a better choice than the pc fan. Go to Home Depot and browse

Dude i thought the same thing but i had 300 plus true watts of cfl's in there. The inline duct booster was 80 cfm with temps at 33c, the Bath Fan was 100 cfm temps down to 27 and comfy so no over kill.

dude just calculate 3x your cubic feet, 5'x5'x?x3 and that's about the actual cfm you need...

pics of wat i got so far

I was having temp issues in my 2X3 cab with a 400. The HID lights heat your walls directly, and they heat your room up with stored heat from the light. The trick is to keep the heat from making it to the wall. I picked up a cool tube. They reduce your light intensity ever so slightly, but you can hang your light really close the plants. Run your exhaust through the tube. Bam, exhaust cooling your room and your light. I was at 32 celcius, now I'm at 25, even after a few hours.
Also, if you havn't already, put your ballast in a seperate compartment.
