Idiots are in controlHmm, that may be although I can only speak to the rules in my state which is 2 plants in any stage of growth which means if I follow the law and want to get the best yield possible I have to grow one full sized plant (6-9 feet tall). Now that's based on keeping the other one as a Mother so I can get the next crop going as quick as possible. Now if I didn't worry about that then I could grow 2 plants full size for maximum yield but then I'll have a significant down time as I get two more going from seed and sexed and properly vegged for doing a full sized plant.
Now they did make some changes to the law because in the beginning before anything took effect they were saying only 2 plants with a combined yield of no more then half a pound, which is insane because if you know what you're doing when growing a full sized plant one plant could potentially exceed that weight limit. Also they were originally saying you could only grow indoor but they since expanded that to also growing outdoor but only on your property or the property of someone else who gave you their permission. Again though that weight limit would be insane because and outdoor plant ground well can yield more then an indoor one. So now they have it to where there is no weight limit on what you grow with your two plants but you can only have on your person 1.5 ounces above that then fines are imposed depending on just how much over the limit.
The outdoor growing doesn't interest me though because it would just invite theft and or mutilation by cats, unless I kept really tight security Of course there is also other worries that go with outdoors such as pests, disease and unwanted pollination. I would much rather grow indoors and now that it's legal I don't have to worry so much about odor control.
