Sorry for brief responses, I respectfully disagree...
12/12 is less time under lights for 6 out of 10 weeks. 18/6 is very expensive and much worse for the environment.
You can easily grow a photo (3 strains) in 10 weeks. You can flower from week 3 under ideal conditions if you wish.
Out yielding will mainly relate to strain/luck of the pheno I think as much as anything else. A good grower versed in both grow styles (auto/photo) will always maximize yield.
If you need CBD you can get specific strains (with far greater CBD content up to 5pct) so there is no medical benefit. Though my knowledge here is admittedly not deep.
If you research your photo strains carefully they are consistently more potent that the autoflowering equivalent. In my own limited experience by about 30-50pct more potent.
Under lights in a legal grow situation I doubt I would grow autos at all. They suit me very well in my situation though and I am very thankful for them.

It is on topic isn't it ? If I was a legal grower for a dispensary there is no way I would grow autoflowering strains. I can see no reason why my opinion cannot be expressed. Can you explain why given the topic one should start a new thread ?
I am not trying to be intentionally obnoxious here but I am afraid it makes no sense. I am pro photo and auto Cannabis but cannot comprehend why a dispensry would grow diluted Indica/Sativa Cannabis strains.
If it is a money and time thing = purely profit based business. I would seek a dispensary that had a different ethic myself. Each to their own mind you. Free world and all that.
