I think at this point if you buy a hype strain or cross of one, especially F1 you pretty much got to expect them. These breeders are using strains known to herm gg4, chem, gsc or descendants of such strains. Then instead of testing the seeds they rush em out the door and in to the next batch of f1. Best bet is to look at how many strains said breeder has released in the last year. If it’s more than 5-10 a year there is no way in my opinion they have tested them. For people that exclusively grow seeds(not sure why but some people do) I would buy from Dutch breeders. I know that the pictures aren’t as pretty but for the most part they still sell the same strains that have been around for a long time. I have never had more than 1 or 2 herms from a pack of Dutch seeds. Now that I’ve been buying American seeds I feel like at least 50/50 chance of each one herming. Seriously hard to even find one keeper per pack of seeds when you got to cut half of them for herming.
