High All, So I've been working on this in my head and on paper for some time. My objectives are as stealth as possible and self contained (veg and flower in one cab and house ballast + scrubber). I've selected the Cab. 70-3/8"H x 47-1/2"W x 20-1/2"D And here's what I've come up with... The thing is, I was basing my design on the idea of only using PC fans. I found some that are rated for 62.5 CFM and only 17db! Trouble is, the more I read the more I'm convinced that they won't cut it. The static pressure stuff...I did make all of the necessary calculations to ensure that the air would be replaced 5x per min and I read that if intake is 1.5x exhaust that pressure wouldn't be an issue...then comes the scrubber. I was planning on using the formulas listed in Randy's post as they were based on the idea of a 65cfm radio shack fan...I'd really hate to get it all together to find that my plants wouldn't grow. So then I decided that I could probably swing a Panasonic Whisperline 240cfm 6" inline fan. http://www2.panasonic.com/consumer-electronics/shop/Building-Products/Ventilation-Systems/Inline-Fans/model.FV-20NLF1.S_11002_7000000000000005702 Knowing that a cool tube was ridiculous w/ a PC fan I opted for the "cool chamber" design, meaning that I will have to raise and lower the plants rather than the light, I think I can handle that. So I guess the question is do you think that temp control will be better with a cool tube, eliminating the glass/PC Fan/intake and vent holes for cool-chamber, or as I am leaning, leaving the cool-chamber in the plan? Thanks in advance! Gratitude

Looks Great Your Cab desing looks great, to bad i dont have lowe"s here... i"ll check in home depot anyways LOL............ why don"t you use a small regular fan.. maybe you can put 2 small in the flowering chamber.. with an ehaust fan and 2 intake fan... also with that kind of space you might be able to put a co2 tank....
You'll want to put a oscilating fan blowing on your plants.I like the glass & just move your plants up & down.That should keep most of the heat out of the flower chamber.The scrubber is going to lower your cfm's .
