New Grower Help me with my fan/ventilation choices!

[CrimsonGhost]

Hey all. Finally getting my first stealth cab all put together here, and I'm a little stuck on fan choices.

The cabinet I'm utilizing is not *quite* 2x2x4, but close enough that I'm comfortable going with those specs. I've got the inside all painted white, and next is ventilation. As it's a stealth grow (and I'm poor) I'm hoping to go with pc fans and homemade filter. So, assuming let's say 16 cu. ft. of grow space - am I good with one 120mm fan pushing 60 cfm and a passive air intake, or do I need two? (either two exhaust with passive intake, or configured as one intake, one exhaust) Also, I'd prefer to keep it simple and just let the fans run run full speed 24/7, rather than bother with a speed controller. Ditto with the homemade filter - I'm reasonably certain I have a good, inexpensive and low-profile solution, so purchasing a commercial filter isn't necessary.

So what sayest thou? One fan w/passive intake? Two fans w/passive intake? Two fans, intake and exhaust?

Halp! :smoking:

Hi. I'm no expert by any stretch, but I'm coming close to the end of my grow of 4 girls so I thought I'd give my opinion. I'm in a 2x4x6 tent, and like you, I didn't really want to spend a lot on this new endeavor. I bought 2 inline booster fans off ebay and hooked up a diy filter. I'm using 2 300w full spectrum led's in my tent and the setup seemed to do just fine for me. Humidity stays in the high 40's and creeps into the low 50's occasionally. My temps have stayed fine with this setup as well even when outside temps reached 95. I figure if my grow space is a little bigger than yours then it should work fine for you. 1 issue you may have is you said a stealth grow. If that means you can't have any smell escaping then you may want to buy a real filter rather than making one. I own a fairly large house and grow in a larger basement with many rooms so smell wasn't really a problem. I'll link the 2 fans I bought for reference. Only $20 each but you get a discount if you order 2 at once. http://www.ebay.com/itm/181192768712 Hope I was able to help a little bit. Good luck with your grow !
