Scrog Cabinet ventilation

[t-pipes420]

Hello,

I have had some free time recently, so I designed this stealth scrog box:



Everything is basically to scale, there is two seperate chambers with the carbon scrubber/exhaust fan in the veg chamber. It is fairly large, 4.5 foot by 3.5 foot flowering area, and 2 ft wide veg. area. I want to use LED lighting, Haight solid state LED grow light 190w (800w hps equiv.) for flowering and a smaller blue LED 30watt array for a couple moms and clones. (Maybe supplement with a couple compact flouros).

Screen area is about 12-16 square feet, hope to get at least a pound every 2 months from it; once I get my shit together.



I have never done a scrog before, or a cabinet grow, so I am mostly wondering about the airflow.

The maroon/red holes are passive air vents and the arrows indicate air flow. There will be a DIY activated carbon filter attached to an exhaust fan. How much fan power do I need, is 200 cfm enough?

Volume is about 100 cubic feet I believe,

And also, how often/how long should the exhaust fan run?

I am thinking C99 for strain at this point. I think it is fairly un-smelly. Any other suggestions for great scrog yielders would be greatly appreciated.
