The Amsterdam seed banks that have been around for decades I do trust. Especially Barney's Farm. Green House Seeds, T.H. Seeds, G13 Labs.They are trusted in my book. I grow a lot of Barney's Farm stuff.
Reason i ask is i watched a podcast last night where they were talking about scam seed breeders, or shotty seed breeders. You know, the basement breeder that has a few 5x5 tents with like 5 females and 5 males and they call that a breeding program. I guess technically it is but you aren't going to get the best of the best doing it on a small scale. They mentioned Jungle Boys and how they attained the top blue chip pheno of Blue Dream. Apparently no one has a better blue dream than they do. And the reason for that is they are a dead serious breeder that are actually hunting for perfection. They do that by planting a room with 5000 plants of blue dream and seeking out the one special Phenotype out of 5000 plants. They say there are more than 4000 different phenotypes marijuana can express.
They were also saying that Amsterdam Seed Banks have fallen behind the U.S in terms of potency and quality. And i tend to believe that because if you look at the varieties they offer these days, Blue Dream, Gelato, Zkittlez, GSC, OG Kush, Sour Diesel, Wedding Cake. Those are all creations out of the U.S. and they are infiltrating the Amsterdam seed shops as hybrids. That says something.
