thicker stems won't snap. Do the bud easily snap off vs. bend/sliver down main branch etc?
If you have 2-way humidity packs, you'll know if it was too dry if buds gain weight. If still losing weight, that's okay for the last few % of original mass in jar w/humidity pack.
if you don't, however you control environtment.. ~55-62% RH and mid-60s F... if it gains weight in that environment, it was too dry.
A little weight gain isn't so bad. It's better to lose the last few% in the controlled environment, though. Too early into jars will increase risk of microbial growth. too late impacts taste a bit. very late will ruin taste no matter how long you cure.
