Long term and after some court cases, we may see home grows under legalization in reasonable amounts but imo, when you follow the money, meaning taxes and back room deals to bump up LP's recreational business, my guestimate if they initially allow home grows for recreational would be 5 indoor or 2 outdoor plant per household maximum (or the equivalent of a 1g/day medical script). To grow above that base limit you'll need to register under a medical program.
There have been hints in some statements from the Libs and HC which point towards a harmonized recreational & medical program, that's the only reason I'm even giving recreational home grows any chance of a probability. If they could do it without immediate and costly repercussions (court cases) I'm sure they'd try banning recreational home grows altogether.
If they allow an initial small amount for recreational home grows, imo that's a win right there as they would never have enough resources to actually inspect/check every potential home grow...
