Legal means Legal. Nobody will care if you grow 10 plants. Hate to break it to you but it is weed, it grows all by it self very well OUTDOORS. Outdoors is superior.  What you think is superior is really only some exotic hybrid. Nobody is going to pay $10 a gram for something they can get for $1-5 a gram or probably FREE. Pot heads smoke 1-2 grams per day, you think someone who doesn't like work can afford $4k-18k per year?
