The best quality cannabis is grown outside and it’s not complicated. You just need good genes, a bunch of good soil, rainwater and lots of sun. Pots are fine as long as they are fairly large.
Some climates are too damp and will leave your buds prone to mold. Worst case you have to cover the plants with a plastic greenhouse. That’s it
Sure, but my friend lives in Canada, not exactly the best latitude to try outdoor growing. Maybe you could get one decent harvest a year, but I wouldn’t even count on that.
