The length of the hang can vary a lot depending on relative humidity, I can typically have things into jars in 3-5 days, but it has taken a week before. The breaking stem is the best way to go, i tend to wait until they stems snap then jar. The jarring causes the moisture trapped in the middle of the buds to escape, may need to open to let moisture out depending on how wet it gets, and then the buds can stew in their smells and flavors, brings out the stank. All buds smell differently to different levels, i have given out bud that i about shot myself for after it was fully cured, smelled like the others before cure, smelled like parmesean cheese after the cure, changes i could have never seen.
