I'm sure someone will have something to complain about. I haven't read the entire petition. I do see they are saying a person might only be able to grow 12 plants but 12 plants can be a great amount. I certainly like the stance against the feds by suggesting CA will not help you prosecute and you will have to prosecute in a CA court. It sounds like a sensible plan. You can grow grapes or whatever and make a certain amount of wine in your basement. It hasn't hurt wine sales. Many wouldn't bother because of the tedious nature. Marijuana for many would be just as tedious. Not everyone grows tomatoes but they buy them and their products. That's the other thing it would open up the door more to commercial ventures. I think on the surface it's a potential win win for all(save for the drug dealers, feds, and law enforcement in general making a career out of it).
