whats the best way for a poor guy to do the glycerin tinc, turn over once a day for 60 to 90 and use ambered buds if no access to oil? What is the max time for max potency doing it this ole fashioned way? Thanks for your time and trouble.
The secret to glycerin extraction is to keep the boundary layers removed by stirring. Shaking doesn't work well, because glycerin is so viscous.
Probably 90 to 120 days cold soak would approach practical limits, though I just pressed a jar of cold soak that I set aside about 5 years ago and found it excellent.
You can get more potency faster using the hot method, but the flavors aren't as provocative, because they all blend together.
