Early or fast versions of feminized strains confuse people because they are neither autos nor ordinary photoperiods. They are made by crossing a photoperiod mother with an autoflower, and the offspring still need the light change but finish a week or two sooner. For reference, https://queenfeminizedseeds.com gives eight to nine weeks as the usual flowering time and tags only Critical, at seven to eight, as a fast finish. The catch is that some lose a bit of yield, and the odd plant may start flowering by itself.
