Interesting documentary focused on the California cannabis industry, the strengths and weaknesses, etc.
It says "California weed is best", although "the California weed industry has been mismanaged".
That part is highly subjective but there are lots of other information tidbits about the technique used and the cost to grow in California.
Typical California premium indoor weed costs around $700 to grow today, too much to pay high taxes, compete with the black market and leave a profit margin.
There is a more interesting section on state-of-the-art "sungrown" weed from Glass House, with 1.5M square feet of of efficient greenhouse, that supposedly produces better weed for as little as $100-200/lb ($6-12/oz). It's corporate weed but it could be good???
It's a 22 min video but easy to watch.
