Between autos and standard photoperiods sits a category often labelled fast or quick, which are photoperiod plants crossed with ruderalis to shave a week or two off flowering without losing the veg stage. They suit growers who want control over plant size but have a short outdoor window. I noticed https://budweedseeds.com separates these into their own filter, which saved me from confusing them with true autoflowers as I had done elsewhere. The yield penalty is smaller than with autos in my experience.
