I'd steer clear of autos, iv done a lot in the last ten years, very unstable genes, some went longer than their feminised counterparts lol I'd recommend doing regular seeds and getting some practice in sexing, regs are much more stable on the whole as femmes, if I had the space time and patience I would always buy regs. But I haven't, I use fems so advice here is to buy clever, don't rush to the most well known breeders as most are crap now, their success has killed their seeds stability, ghs for example. There's a site that documents all cannabis strains, here you can read reviews about 1000s diff strains from all the breeders, do a bit of research. Get something established that's known for stability and growing ease, tbh, they grow all the same , one is not so different to another once you've got everything boxed off
