Ck out the growlogs for similar techniques. A small 150w hps would be ideal, but you may have to make it slightly taller to fit that light and there will be heat issues, so a small PC fan or something similar to move the air around and bring in fresh air will be needed...a box that small will have to have good ventilation or the plant will use up all available co2 very quickly...no co2=no growth. Ck these out...

TANKJR Reviewed by TANKJR on . need info or direction to info please looking to build an extremely small box in hopes of cutting down on smell and energy usage. ideally id like to use autoflowering seeds so it can be a quick operation. so im thinking of making a 12"x12"x12" box with one good high efficiency light. im only wanting to grow a single plant at a time, nothing radical. not looking for huge yield, just something that i can toke occaisionally and have excellent potency. please advise or direct me to the spot where i can get some good advice. thanks!!
