If I were to build a cabinet from 3/4 inch thick plywood, what would be the optimum height? I was going to say four feet. I'd be using all CFL's. Possibly a 150 watt HPS for flower. 2-3 plants. Just for personal use. I was thinking maybe 4'H x 3'L x 2'W.....what do you think? Good size cab for 2-3 girls? What kind of plywood would you use? I was going to line it with panda film or something. Or just paint it flat white? The design I am going with is going to use two PC fans. One for the heat exhaust. bout 80CFM. going to be using a 1/4 inch thick piece of glass i found in someones garbage, i think it was from a coffee table or something. The second PC fan is for the odor filter. DIY all the way, only 40 CFM I believe for this. Ive got a good carbon filter design from a member of icmag. Will have a good size intake cut from the very bottom. What are your thoughts?
