well what are you thinking about doing? growing indoors or outdoors? There is several pros and cons to both
Indoors
pros - Less likely to get caught, can take better care of your plants
cons - It can be expensive but for just a little setup of 4 plants you can probly get that going with under a $100 bucks if you are not buying seeds online.
Outdoors
pros - plants can get huge.. no lights, cheaper
cons - more likely to get caught if you have neighbors or something, cant control everything, might not get as good as a harvest.
but i do think anybody that does smoke weed should grow because its fun as hell i love doing it. If i could move over to Amsterdam and just operate a green house for a cafe or something, I would deff drop out of college and go lol..
