Lots of small growers, that's the California scene, and since they're constantly hassled by law enforcement, I think we made the right choice in heavier regulation despite the harm done to the localized market, it technically doesn't exist on a legal level anymore, giving the small growers a new role, "moonshiners", less attention for them, more people smoking their Cannabis, this is the way of regulated commodities, history channel, where are you?
OTOH, medical growing continues unchanged in CO, iirc. I think there's still room for little(ish) growers there. Dunno, really. I only came back to the scene after A64 passed & I was headed for retirement. I just know a little around the edges of that, having never been a participant.
If the quality & after tax price of retail ever becomes better than/ equal to medical, they'll have problems. We really need to figure out how to integrate the 2 markets in a more sensible way somewhere down the road.
Three years from today, the market will be entirely different, maybe different than we can imagine. Outfits who figure it out, provide customers with what they want will likely make gobs of money.
