What happens when you hang it. Is you dry the outside of it. There is still moisture in the middle. When you put it in the jar you draw that moisture out of the center. Back into the outside material. Burping it once a day will let some of that moisture out a little at a time. Then when you think you are close you burp once a week till you get it prefect. I believe the longer you take the better it will be. For me the idea is to get to like 10 to 15% moisture evenly throughout the bud, and to take as long as I can getting there.
But didn't you say this is your first harvest. Yeah you'll be lucky to get it in to the jar without smoking it all. lol
Have fun and enjoy
Peace
