I've got a DutchPasion AutoNightQueen that didn't begin flowering until 10 weeks.
It's now in its 18th week, and might be ready at the end of the week.
Several months ago a WorldOfSeeds NorthernLightsXBigBud took 17 weeks to finish and yielded 15 oz dry.
It got about 7 feet tall and grew into the lights.
It had a whole 3' x 3' tent to itself for several weeks, which increased yield.
It's debatable whether an auto can be triggered by 12-12 lights.
Any auto triggered by 12 -12 probably isn't an auto.
