That's good that you noticed the other buds started to dry out, but... PUT THE FRICKEN LID BACK ON !!! BLAH !! Seriously.. yeah they probably make hygrometers that measures humidity in side of jars. Learn how to tell from FEEL. Not crispy and to moist. I would also say, that any homegrown that's cured well, and ready for storage, should be in the freezer. Peace
