if u wanna start a grow, read and ask a lot of advice before ok? this sucks when u start somethin then u understand that u just messed up and u gotta male or you shit your thing. anyway, buy a timer, so u can put your light at 18 hours of light, then 6 of dark, for about 1 month, maybe 2. then turn it to 12/12. u need to use fertilizers after 2 weeks of vegging. a fan is good too. mylar is the best to reflect light, or aluminium foil.

u need to use lights such as high pressure sodium, metal halide or bulbs. halogen or house lamps wont work, trust me. good luck!

peace
