Well I say you should go for it. sounds like a great opportunity and grow boxes really do help control the odor. But definitely don't buy one, make one yourself. Tmoney might have intimidated you with all the equipment he told you to buy, (4 600W HPS convertable to run both halide and hps, 2 500CFM extraction fans, 4 oscilating fans, 4 carbon filters) but you really don't need any expensive equipment. I built my grow box out of old bookshelf wood that I found in my basement, and built a lil hydroponic system into it. the whole thing cost me less than 60 bucks. Well the wood was free, but besides that all I needed were two CFL's (those are the compact fluorescents they sell everywhere to replace regular incandescent bulbs, they cost like 4 bucks each), a 20 dollar water pump, some vinyl tubing, a couple electric timers,and some silicone gel (to seal the holes), all of which you can buy at lowes or home depot. The other stuff like the rock wool and hydroton is also very cheap, but a little harder to find. But you won't even have to worry about that if you're just growing in soil. But yea I say go for it, and definitely build it yourself, itll be a fun project if anything :thumbsup:

Im including a few pics of mine, taken before I started growing anything. Mine is tiny, made for only one plant, but making a bigger one shouldn't be too hard. Same basic principles.
