I have very close to the same cabinet, except that I'm a soil guy. I think your plans will work very well. Let me recommend that you get a 6" fan and dial it down. That way, if you should ever need more ventilation power, just dial it back up.

As for strains that would work good with SCroG, I will recommend Nirvana's AK-48. I have grown it several times now (and will again in the future), and it's an excellent strain, easy to grow, forgiving of mistakes, robust, great buds that also *look* great, and the seeds are about the cheapest you can buy (got mine at seedboutique.com, $15 for a pack of ten).
jamstigator Reviewed by jamstigator on . Ebb & Flow Hydro Cab Plans, please review I did some reading and threw together a plan. The dimensions will be approx 4' wide by 2' deep and 6' tall. I still have some more research to do, but I thought I'd run this preliminary plan by you guys. My 2 biggest concerns were ventilation and keeping the reservoir cool. I think that with the ebb and flow system, my reservoir would be spared most of the heat from the lights since its separate on the bottom and room temperature air would be flowing in through the darkroom louvers.
