To be honest I have no experience with Autos but if were talking early finishing photos that would be likely to resist mold, & stay relatively short theres 2 strains that come to mind:
1)
HSO's "Black D.O.G." which was an awesome grower/quantity/stone and finish time of like 58 days for me...Im talking done done at 58. Full on black leaves orange hairs and amber frost. Taste was amazing and I know a couple great breeders currently working with it that have had the same results with it that I experienced. Blackberry flavor all the way to the roach. Amazing terps and bag appeal for days.
2)
BOG's "Lifesaver" which was up there for fast finishes. Its been boasted as his fastest finisher for years. My fastest finisher with those was like 52 days or something I believe? It was yrs ago so I may be +/- a day or two, but I do remember it being astonishingly fast and sub 55 days. On top of it being a very fast finisher, she was a quality smoke that was like grape bubble tape bubble gum. Tasted just like it smelled when dried and burned. Come to think of it, I may just revisit that one again now that Im thinking about it haha
disclaimer: I had gifted some "Lifesaver" seeds to a good friend of mine on here and he had the exact opposite experience with finishing times. I believe it was closer to 70 and possibly could have went longer.
Pretty sure both are still available from both breeders also. Best of luck with your seeds
