thanx blaze that helps alot, but i think imma go with the 250 cuz like i said i only need one or two plants, just for personal use..+ i can get a minisystem thats a 250 hps with a built in ballast (are these ok to use?). i really dont want to get that indepth with my growing i just want some stuff i know isnt fooled around with. because dealers from around my area have been known to raid the buds they sellto "make them stronger". which is the dumbest thing ive ever heard.

and i really dont care how much each of my plants yield even if its only 1 oz per. cuz i dont really smoke that much. thanx for all the help guys

P.S kush what are the dementions of ur grow room and how many plants do u grow with the 150?
