If I were you I would find a nice outdoor growing spot at some random place and plant them. And if you're lucky no1 will find them in a while

I knew a guy who went kayaking down some river and stopped up on some bank to have a smoke and he planted a few seeds from his bag or something. Anyway a few months later he went rafting down the same river and guess what he saw towering a couple of feet about the shrubs...

But there is always a risk in growing weed no mater what part of the world u are in so be prepared to loose your babies.
