what size fans are you looking for?

[Tiny420]

Not to big maybe 4" or bigger

cool, I gotta couple of links for ya. the first one is a 120mm DC computer case fan. I'm currently using one of these, works great, also very quiet. all you need to hook it up is an old ac adapter.

Thermaltake Silent CAT 120mm Case Fan - White A2329 at TigerDirect.com

the second one is an ebay store. when I upgrade I might go with these guys. (p.s. they have crazy deals on lights too.)

eBay Store ââ?¬â?? High Tech Garden Supply: Search results for.

and here's another site I came across, I've not dealt with these guys but thought they had some good deals.

Depends on how big bulbs you go with.

You generally only need or want exhaust...not intakes.

Go with passive intakes...2 small one way flaps for each 4" fan. Do not use computer or cpu fans. Get a real exhaust fan from THD and place it highest in the box and place your intakes lowest in the box.

You want to develop negative pressure so you are sucking in cool bottom air and expelling higher hot air. Everything else must be tight for this to work.

Be sure and get some of that pre-filter black fiber stuff from THD as well (Near the air purifiers.) you DO want to filter the incoming air PRIOR to getting it in your grow box. Wrap the filter and clamp it on or tape it on the intakes. It also will help darken the light escaping.

Good Luck

get a inline duct booster fan, they are awesome, and for an 8" one at HomeDepot I think its like 29.99, cant beat that, and it moves 210cfm, that aint bad, get 2 of those and you almot have a $300 fan, works for me.

Nice info Hardon and ForgetClassC
how about a bathroom fart fan from the hardware store, variety of sizes, quality, level of noise, prices.

just a thought...
