well i grow because i fell into being a pothead which i love and then growing just became a hobby for me...i rarely sell mine but i have figured up on my crop producing 17-21 oz. a yeild which is around $20 a gram which i usually sell if i do. but if i would sell all of what i grow i could prolly pull around 8G per plant giving the selling price of an ounce. but its more became a hobby and i smoke what i grow and i share. i share for free actually lol and all my friends love me for it cause im letting them smoke some good stuff for free...who couldnt ask for more!?
