Most autoflower seeds on the market are feminized, and regular autos have become quite hard to find. Breeders who want to create new autoflower lines still need them, since male autos are required for proper crosses. Only a small number of regular autoflower options appear at https://budweedseeds.com compared with the feminized range, which matches what I see in other catalogues. For simply growing buds at home, feminized autos are the more practical choice anyway.
