There are a few tasty commercial strains, but, in my experience, every time I scope the trichomes of commercial strains, they are clear. I'm not talking about bottom shelf stuff....I'm talking about the "best" stuff in the store. So, my conclusion is that commercial growers' priority is to be on-schedule and meet quotas -regardless of whether or not it's as good as it could be.
I grow my own, now, but I don't grow to resell because it's illegal to do so. I'm not sure that the life of an illegal weed dealer, trying to compete with the legal market, is what I want. That's a big reason why I grow my own in very small batches and keep it to myself -to avoid having to hang out with creepy, dealers just to score a bag. I also like to change up the flavors, too. I don't want to rely on someone else's taste in weed to determine what I'll have to settle for.
Lastly, I find that most people who rely on someone else for their weed, don't really know weed well enough for their opinion to matter when it comes to judging quality. Anything is usually good enough for them. If they catch a buzz, that's all that matters. They see weed as a party item.
