Lets bring this topic back from the dead........
To address the Oregon question, yes you can have 24 plants. A single patient is permitted to cultivate 6 plants over 1 ft tall/wide and 18 clones which do not exceed the 1 ft tall/wide limit. Basically one patient can grow 6 plants at any one given time while maintaining numerous small clones to ensure a continued harvest. A patient can also be a grower for other patients. Any one grower can possess and grow for 4 patients including themselves. This 4 patient limit keeps the max plant number amount at 96 (24 large mature, 72 clones) which keeps growers legal and free from most attacks by the feds. Keep in mind, there is a strict licensing requirement with the state similar to the new law in AZ.
But.......in Washington. A patient can cultivate 15 plants of ANY size and is permitted to grow for one other patient equaling 30 plants total. Furthermore, an amendment this summer legalized collective grows. 45 plants of any size at one property as long at least 3 patients have their doctors recommendations posted at the physical grow site. Ya see....there is no official state registry system. Basically you go to a doctor, get an authorization which is nothing but a signed piece of paper and boom! your legal. You carry it with you in a wallet and pin up a copy at the grow site. The state has no clue where patients are or where their growing. The only time you have to prove your a patient is when the shit hits the fan! Which, most likely never happens.
I think you got it good in AZ. I think about coming back sometimes. 12 plants per patient, 5 patients per residence (possibly 6 depending on how the law is interpreted). 60 plants of any size!!!!!!! That's the thing dreams are made of. The 25 mile rule won't matter in a year or two anyway. I think that tricky little piece of language will be removed from the law. Especially when most patients are testing the waters growing for themselves. The public outcry from mmj users who will have their right to grow taken from them after all of the time and money put into making proper grow facilities, etc..... will stir up a controversy and a ballot initiative to amend the law and cut out the 25 mile rule. The state knows it's absurd and now realizes it was just all an attempt to hustle patients into being forced to buying instead of growing their own.
oh.....stay away from Alaska. Its like another country out there. Seriously!!
