An experiment:
Day 2. No roots
Day 3. Note - Korin is dropping seeds on their own occasionally. I will continue this experiment to get a better sense of how seeds mature but I think it’s probably moot if they can be kept on the live plant until they fall on their own.
Maturing on the plant > drying in the lab.
Tossed them. I think immature seeds must be fed to birds. I do want to do a successful germ test before I put them aside. Let them brown on the live plant seems optimal.
Note 10/15/19
I continue to try germing herm seeds. Out of about 50 so far, one popped a root. The most recent batch got a sandpaper shake. Plenty more maturing on the plant.
