Optimally lighting a small flower cab

Hi guys, I'm planning my first grow and wanted an opinion on a lighting solution. My cab is 2'x3'x5', 6sq/ft. I want the benefits of hid and cob so I was thinking 2 50 watt cobs and a small hps, 150 or 250 watts. Hps in between the 2 cobs for 250 or 350 watts actual draw. Let me hear your advice on the light itself, ventilation and if this will be beneficial or just get a (3) cxm 22 cob kit. If I do the cobs should they all be 3000k or should I mix. Thanks in advance

Stick with COBs. The HPS will do little more than add heat while you're plants fight for position under the COBs.

I've been there. Added 2 COBs totaling 110w to my 400w HPS. My plants were all reaching for the COBs within a few hours, like an ancient civilization that found a new God.

whatever you want really, best case a QB would be great simply because of height profile.

but, your biggest problems will be air, and temps.

i'd go with a quantum board as well, seems like the perfect fit for your set up.

this would work, and not a big investment.

I do some research, another question in a space this small even under optimum conditions, how much bud can you get out of 6sq/ft? In a small space with high temps and humidity which growing medium is most recommended. I really like the yields I see from one waterfarm but I think Coco and smartpots are easier to maintain. Thanks guys Im doing my homework and planning everything out before I start a Grow. I be visiting ROI a lot in the future
