The "autoflower" is just ruderalis genetics that allow the plant to flower without changing light cycle to 12/12. You can have both male and female autoflower, however most sold from seed banks are feminized
Interesting. I’m aware of the cross genetics of Ruderalis, but I don’t see any reason to offer a male variety, and I would imagine it would be even more difficult to select the seeds for it as well.
Edit. Just found this.
While feminized seeds are extremely common, and make up the majority of the autoflower market, regular autoflower seeds do exist, and even the
male cannabis plants autoflower too. Having feminized seeds is a great option for large scale production as it takes out the labor involved in removing the male plants and helps ensure a seedless crop. Feminized seeds are more expensive, but provide the convenience of not having to sex the plants.
