Looks like this is another thread/post where someone like me, an old school smoker, is trying to get advice on where to buy seeds that contain that old school genetics (kind, skunk, chronic, piff, etc).
I gave up doing this because the answers all vary. So after doing research on sites like this one, reddit, and other marijuana sites, I just decided to grow seeds that are supposedly old school. LIke Mr Nice, Piff Coast, etc.
I will know for sure in a couple months when my gear harvests, however, for now, old school weed is like a snipe hunt. It's an urban legend. It used to be around, people remember it, people smoked it, but it's not around anymore.
Don't ask me how the good old school bud has disappeared. It's like Berenstain Bears. I remember it being Berenstein but the evidence you see now points otherwise.
