Probably want to make your own seeds hey ;), so you don’t always have to buy. Reason why i make my own fem seeds.
But to the question Mitch “mephisto” hasn’t released any standard autos yet, he’s talked about it, and im definitely on that train when it comes along.
But honestly their are very few, Stitch from Flash Seeds has a bunch of regulars, he went through some issues with having others produce seeds for him and those seeds having germination and other issues as he didn’t have control over it, but that’s been sorted for a bit now.
Another option is some of the lines over at the auto flower portal they get decent reviews, and some such as the dragons were bred by a fellow “Stone” using some of mossy’s gems which a lot of people liked shes a member over on AFN “autoflowernetwork” im over there as well, just haven’t posted in a awhile since moving here to OG
But if looking for regular auto’s those would be the two places where i would start. I haven’t tried any of Stitch’s or the AutoflowerPortal seeds yet so i can’t really comment on them, but i will get some of both eventually to try out.
Other than that its going to personal growers with their own auto lines or crosses they have done.
