Measure humidity in buds

[AutoflowerChief]

Maybe my search skills are not developed enough, in that case I apologize...

Question:
I measure by touch, whether the buds may be dry enough to start curing.

Now, I put the buds into a jar. I throw in a hygrometer, too. I close the jar.

Will, after some time, the hygrometer give me an accurate reading of the buds humidity?
Or is there some magic mathematical formula to calculate the bud's humidity from the jar's humidity?
Or what should the hygrometer read in the case I'm good to go on with curing?

Hygrometer in the jar will give you a reading of the relative humidity/rH of the jar's air. This is the common method for measuring buds-in-a-container rH. But if you are confident in your just feeling/examining the buds, that's presumably just as good; or maybe even the best way. [That's what I do]..

With enough time, the hygrometer reading should fairly well correlate with the amount of free/releasable/unbound water in the buds. Water not readily released into the air, the water strongly adsorbed to or trapped/covered by cellulose fibers or other plant components, is not measured.
