Autos have come a long way since I've been growing them. My first autos were from joint doctor, stitch and short stuff....almost 20 years ago.
Always in search of the lost chord, autos have changed as breeders and pollen chunkers have bastardized the auto process which has increased quality and yeild but at the same time changed basic auto genetics. Autos were originally developed for their size as well as their timeliness of bloom...improvement came by mixing photo genes and minimizing the ruderalis and now we have what we have.
Growing perpetually all these years, I've bought a bunch of seeds, both photo and auto.....since I follow my own rules and grow 12/12, I can grow anything I wish.
My advice, buy known genetics from reputable breeders and distributors....There's some impressive ones available.
