dude i know exactly how you feel. i started growing BEFORE i ever smoked. Its weird, but i love growing probably more than any thing else, almost more than smoking.
I had to stop recently, (college, dorms, etc...) and i hate every second im not growing.
Its a fun hobby and i have learned alot about patience and what not. Just remember that having fun growing isnt worth going to jail for a long time, dont grow too many plants or you will get caught and you will be sorry.... jus my 2 cents
