There could be another add on to this thread, about weight.
A64 says you can possess 1 ounce, but it also says you can keep your entire harvest , talk about confliction.
Say you have 3 plants, all are scrogged tree bushes, all yield 8 ounces per plant, now you possess 24 ounces.
My thoughts would be your OK as long as when you travel somewhere outside your house, you possess no more than 1 ounce.
I don't see no DA trying to prosecute a marijuana case now unless there is private unregulated selling going on or someone is growing well over the limit. There were a lot of CO county DA offices that took a lot of marijuana cases they were scheduled to try and trashed them the week after A64 passed. I just don't see any DA trying to prosecute a CO resident growing 12 plants on some type of technicality gray area of legal-limbo. As for El Paso County in the CO Springs area, now those conservative assholes might, but as for the rest of the state in my opinion I don;t see it happening.Any CO cop now would be thinking about their job security for attempting to make an arrest on someone growing a few plants over the limit and I don't see any CO cop making an arrest on someone who is growing 12 plants that is claiming 6 recreational and 6 medical.
This is just my opinion, best way to get a certain answer is call someone like Rob Corry.
