Most of them aren’t gunning for quality. That’s why “home grown” means “bad”. They’re looking for low risk production, which is what the national parks have (accidentally) provided for a very long time.
I don’t know about that. A lot of the fields they’ve been finding now are actually planted with thousands of rooted cuttings from female plants rather than having been started from seed. This way all the plants are female and the buds get bigger and more resinous and never go to seed. Also, a lot of these huge plots have extensive irrigation. It looks like even the Mexicans are starting to try to produce higher quality product so they can sell it for more money. They’re putting a lot of work into it.
