I wouldn't plan on being able to unload product grown from cuts you get at dispensaries. If they have the cuts, chances are the same person who sold them those cuts also already sells them the nugs. For me, I'd either breed my own strain or at the very least pick seeds with quality genetics (and that doesn't mean Can. Cup Winners lol) whose seed stock are in limited numbers. At least then there is less of a chance for someone else to be growing the same strain. On top of that flower two packs or more to find the best pheno that will separate yourself from anyone else who is growing the same strain. Give it the right growing conditions and a quality cure and you at least give yourself a chance at unloading some product.
As far as the law goes, it depends on your perspective. There will be people who are petrified of going one leaf over whatever their plant limit is or even one gram over whatever their dried material limit is. And on the other hand there are people who will fill every room in a house up with plants, whether in a medical state or not. You need to decide for yourself what risks you're willing to take. With risk comes reward, remember that. I would feel more comfortable in my own house with a 6kw unregistered grow than one that is set up as a collective with the state. I can bring all my equipment in from out of state, go to the hydro store in a vehicle not registered in my name, and even unload my product by using someone else's car. The risks that I will encounter are my heat signature from the lights, my electricity usage, and those who wish to rob me. I am not concerned for my heat signature as they need a warrant to view it legally as FLIR cameras can be considered an invasive search. My electricity is not stolen, and my bills are paid so they electric co. has no need to nudge into my business. Robbers are the only thing that scare me. In WA I went threw hoops to make sure no one fallowed me home because people will try. So for me to have a 6kw grow is not a big deal, as I have not done anything to warrant somebody to look into my affairs.
With collectives you are on a list. An even shorter list than the one they keep for registered patients. So if the police or feds want someone to bust, they already know a good place to start looking. Record keeping is great for the state, but only provides the feds with more evidence against you. Growing for profit or non-profit is illegal either way under federal law, and the IRS will not hold any pitty for you either. Not to mention that with collectives more people are involved, and more people equals more lips. More lips means more words, and word gets around fast.
But things can go either way in this world. As an end to my rant, I'll share two life experiences. I had a friend (we no longer speak due to how he handled himself in this situation) who had some good Cali connects from his time in school there. When he moved back here, he started to have weed shipped over from Ca. to our area. Just an oz at a time, but they were coming in on a regular basis. The cops were called to a party he was having and arrested him for posession. It just so happened that this same day he recieved one of his special CA packages. Cops found it, and before they opened it he was already blabbing about his friend who worked a collective and would ship him weed per request. An investigation was opened, several packages were sent, and then the arrests were made. My friend got probation, and lives his life as normal and found someone else to send him weed. Our friends from CA, not so lucky.
On the flip side another aquaintance of mine was busted for a closet CFL grow when a a search warrant was served at his house for his girlfriend. The cops were not looking for pot, but a closed closet door can provicde space for someone to hide or in this case for plants to grow. Since it was a valid search warrant giving them permission to fully search the house, the bust stood in court and he was sentenced to two years.
