I don`t normally blame the breeder
You have no clue what set up they grew in
but 50% of the time auto`s will grow shit that`s what you get for having an auto seed, the ruderalis makes them grow tiny and flower way too soon and such, maybe something that was 70% sativa or more with only a bit of auto in it would do better
I just use autos to fill space or if I want something that will flower in my veg area or under 24/7 lighting, oh yeah there good for cold countries outside or places where you have really long days in the summer
but saying that c99 will flower 16/8 ok it go`s a bit better at 14/10 or under 12 but still flowers pretty nice
try mixing up breeders next time see if you find one you like better
but my advice would be ditch the autos or only go for ones you`ve seen grow big as most autos can be really hard to get to grow big and an auto x pure indica is going to be small like 300mm to 1m max maybe 7g to 100g yield obviously there`s tons of variables but a good pure kush can get you 300g to 1kg per plant with a good 4 to 10 weeks of veg
So the ruderalis genes kill the yield for sure
