i like what you are doing...i tried to grow when i was like 14 and my dad found out..oh well...
from what i understand: i hate to tell you, but i dont think much is going to happen with what you have now. the plant will get too tall, it will smell up the whole house, and you are more than likely going to get busted. for safty reasons, dont say shit to anyone, no friends, dont tell people you dont know, be fucking safe.
now, fuck the kb, yes its good shit but for what you are doing it doesnt seem like the best thing. heres what i would do if i were you: get a money order and buy some lowryder seeds, they stay like a foot tall, and can yeild fairly decent. it might not be the best smoke but from what it looks like you could fit about 4 plants in there. buy like 2 100w cfl, 3 from wally world are like $10.

remember the key points. safty, tell no one, lowryder, 100w cfl!!! good luck and keep us posted dawg.
