or just wait, dont grow....get your own place before you potentially fuck your parents out of everything they have worked hard for. dude a pc box is out of the question, im a first timer too but my shits already 5ft tall! and im freakin out cause my space isnt big enough, a 1.5ft pc box wont do shit, secondly what are you gonna do when your room starts to stink? and thirdly dont listen to your dumb ass highschool friend, cant get 40g out of a pc....where u gonna put the lights? and how much do you think a plant could yield if it were only 24in.?
