There was no designation of F2, or F3, written on the seed pack either. I assume what's written on the pack is done so by AKBB not JBC, therefore I don't think the lack generation designation has anything to do with JBC.
My assumption was that they were F1's, but I really have no idea. I did have a very brief moment of FOMO when I realized there were so many different versions and I really had no idea if the version that I bought was the same as what he referenced in the podcast.
But I'm not actually worried, either way the genes that I was curious about are all in there.
It's all a roll of the dice with any strain, I'm excited to get a chance to see what I get!
