aight, bro... ur first post came off bad, just to be honest. its like you dropped into the middle of book and said, "alright, now what just happened?"
later posts seem to indicate that you do have more than one 'level' in your brain and aren't necesarily just some kid...
so here's the first tip: spend less time with your homies or on the street or listening to rap music or whatever it is that has you coming off like a gangsta. if your going to grow then you need to start looking and sounding like a prep, the good neighbor that's schmucking it 9-5 like everyone else. Hell, play country music when ur pulling into your own driveway. And fly an american flag in your front yard.
Other than that, the answer to your question is 'all around you'. This entire forum is dedicated to successfully growing a crop, small or large.
No one can tell you how to sell weed or make money doing it. Cuz the whole thing involves interactions that are prone to error and illegality and letting your arse hang in the breeze. So, if you're gonna grow, then grow. If you're gonna sell, then sell. But don't try to do both... or your just asking for trouble.
