To grow 100 plants with a plan to sell it all is not legal.
even acquiring the materials to do it is, conspiring to cultivate a controlled substance with the intent to distribute.
if you dont get busted you will get robbed, that is over 50grand of smoke do you need that much? are you prepared and armed to defend it and your self?
you have already figured out one way you can lose it all,
to cut your losses plant the crop in stages so the harvest is not all on one day or week or
tell the guy you got your half already sold to pay off a gambling debt and the cash for the nutes is coming out of the total payoff and if you dont provide the buds a few SUVs will pull up and a bunch of guys will hop out and cut off his and your feet.
greedy ideas like this are what will kill the legalization movement it was not created so people can get rich quick or get shot in the attempt.
grow two plants in a closet and harvest a QP every 2 months.
then enjoy the fact that you can grow, without worrying about your door getting kicked in at any moment... by the cops or by the guys pretending to be cops.
that is worth more than 50grand to me.
