I think that the limit of four plants is quite low and avoids the risk of diversion. Of course, for anything they put together, people will be right behind it finding a loophole, whether it's making the plant grow five metres horizontally instead of vertically, which would avoid the whole height limitation, or pooling resources so that if they have a neighbour who doesn't grow, they'll ask whether they can put four plants in their backyard. You make something and within five minutes someone finds a workaround.
Definitely, however, home growing must be permitted under the act for people to have the choice. If they do not believe in the government system, they can make it themselves. People grow tomatoes. I'm not sure how many plants, but you can grow your own tobacco. You can make your own wine. You can make your beer. Why would marijuana be different?
I think the limits are rather low, but I guess you have to find a happy medium. We'll start with four.
I think all of the measures in the bill need to be revisited as well. We talk about flying the plane while we're building it. We're definitely doing that here. We are in uncharted waters. Legal marijuana hardly exists on the whole planet, so we have to be able to revisit these measures down the road and perhaps increase the number of plants permitted or find other measures. I know that in the United States they go by square footage of canopy. You can have 100 plants that fit in an area one metre by one metre or you can have one plant that's the size of a Christmas tree. Going by the number of plants may not be the best gauge to achieve the objective you're looking for.
