I can see someone making a case for a later harvest but It has a lot more character with the earlier harvest, both in smell and effect.
I made some hash and I'm somewhat pleased with it but I've been selecting it for the bud and not the hash and I think the hash has suffered as a result.
This year was the first I experimented with STS, I have a few hundred seeds, I'm not sure when I'll find the time to test the seeds out, it was mostly done for preservation if I ever lost the clone. I really want to go through the Ethiopian seeds I have before. I stored some pollen in the freezer, I really want to go through the Ethiopian this winter.
