I am in the same situation, not in a studio though and I only use a 250 to flower, but I say go for it. My landlord includes the electricity in the rent and I make sure and pay on time every month and have yet to have any problems. Don't listen to people saying just buy a sack and you'll be fine, that is not a good use of your money if you have the option to grow your own. Let's see you could be paying ~$300-400 per oz every few weeks/months, or you could spend that same $300 and get a couple #'s. Which one seems like a better use of your money?
i MUST be doing something wrong. #'s from $300??
