I’ve never grown any autos, but I remember an old thread showing that the auto under longer lighting period grew bigger (and matured faster?) than the one under shorter periods. What the periods were and the point of yield vs power used I can’t recall.
I do read mentions of successive planting of autos for multiple harvests outdoors, does that not work out with true autos?
With marks “super/semi auto” I think those are the f1 crossing, like his 90 or 105 day strains… While selective breeding of the f2 should make the f3 true autos. Then his 60 day strains are suppose to be true autos.
Someday, I may try testing an auto vs photo going 12/12 from seed. Maybe Compared to an auto under 24hr of light. But the strains would prob have to match as close as possible for it to be a fair comparison.
