that's very true, genetics play a huge roll. with photoperiods you can run a clone again and again to see if you can get different results, but the one and done thing with autos you will never really know unless you know how stable the genetic is.
I think most of the seed banks that "breed their own" seeds that have many different strains they are calling their own that we have all seen everywhere before. eg. local SeedBankX will have an auto girl scout cookie for sale in their packaging, but they did not actually breed that genetic, cause we all know it to be something that already exists. They also can't open a pack of Ripper seeds and throw the seeds into a pack with their name on it and call it their own, infact they will loose money also as these seeds are relatively cheaper than the legit stuff from the reputed breeders such as Ripper, Inhouse, Compound, Square1, Riot. a lot of the US guys got the legit shit. these local big time seed bank guys with bulk bulk sales and ALL the strains make F1's or just do small pheno hunts, select the winner and BX it and sell those seeds for cheap, at least it's better than F1's, but a lot of times they kinda just "pollen chuck" and hope for the best.
no way you can do legit work on that scale so quick, plus the names give it away. our local master breeder here is Totemic, look at is work, you'll see new strain names cause it's his own crosses and he works one or two strains at a time till he feels good about it, not 100 strains all at once and just one pollen chuck and done.
I've grown out some biltong and buds photoperiods under the sun, their setup us a good example. Just before I started growing indoor. Phenos didn't look anything alike. was just some average weed, not even good weed. grew about 10 different seeds of the same strain before I gave up on digging for a good pheno. don't get me wrong, some guy somewhere got a pack of BnB and he got a winner pheno, probably a few people, but those guys got lucky.
