Hello i have 10 42 watt 2700k cfls and i was wondering what kind of a fan i need to keep the tempature good in a growbox...also it needs to be queit for stealth, and cheap on my shit budget.... i will probly add a fan controler to it beacuse i wont have all 10 cfls at first... I will cover the whole box in mylar too.
Thanks for any input

bump!..... no one can help??

I have roughly the same setup. All I did is went to the cheapest discount store around and got a $12 10 inch 3 speed box fan for my exhaust, then I went on eBay and got a 84 CFM computer fan ($9 shipped) for intake. It works just fine for me. I wish the box fan was smaller though, but it was the smallest I could find at the time..

Oh and as far as stealth goes. With my closet doors shut I can't hear it above my PS3's fan, or if there is any ambient noise really. But yea if its pretty quite I can hear it.

im using 20 100 watt no fan at all its very mild

Thanks for your help Lowhz. Where did u find that box fan?? do u know any stores in canada that would have one because that seams like a ausome deal.

Place in the states called National Wholesale Liquidators. Don't know much about the Canadian fan market lol sorry. The brand name is Optimus and the model is F-1022S. Maybe you could look for it at a online store or eBay. You could try checking dollar stores too. Actually now that I look at the box it was only $10, so yea its not too bad. It doesn't say a CFM rating anywhere, but it moves a good amount of air.

Ok, ill look for something simular... but i was thinking with a grow box inside of a closet wouldnt all the hot air exasting just heat up the closet therfor the intake would be sucking in hot air?

I'm using a 110CFM bath fan from Crappy tire, the 1.5 sonne model so it is virtually silent. Wasn't cheap at $115 on sale but ventilation can never be cheaped out on as it will only cost you the price of doing it twice or more.

My Veg chamber is 2x2x4 feet with 528W of CFLs and the warmest it has gotten is 82-83*F with mid 70ies the norm.

jeez i was just at canadian tire shoulda looked... so ill look for a bathroom fan next time.
thanks

I bought a 4 inch inline fan that moves 315cfm on ebay for 26$ shipped and its plenty enought.. I could have got away buying the cheaper 20 dollar 3inch inline fan and still have no prob with heat. Why would you buy a 115 bathroom fan? The reason why its expensive is because its a bathroom inline fan instead of a basic inline fan. Trust me, i paid 26 bux and have no prob with heat or noise...
