I am not sure good stock and hermie go in the same sentence.
Valid point, and you're right, but I've seen a few "Name Strains" throw a hermie every now and then so it's not a big definer for me, I see it as a bonus every now and then.
But I've only ever grown for personal use and pleasure gardening so a few seeds has never bothered me. If it smokes good I'm happy. I guess there is a sliding scale at the crap level as well, and what I think is junk, someone else may be quite happy with. It's all about the herb in end.
Cheers n Peace
