I’ve never been able to get my stems to snap. I usually dry for 7-10 days, then jar it up. I’ll check the jars in a few hours- because any remaining humidity inside the buds will be more noticeable. I’ve been know to leave the lid off for a hour or two if I feel the humidity inside the jar is too high.
Just make sure you open the jars everyday to exchange the air inside for the first 2-3 weeks, and then once every few days after that. 🌱
