I assume you meant to say 70%?


Sounds about right, things will stabilize after a day or two. Basically, the cigars you added took up the empty air space, leaving less air for the moisture to occupy.

Cigars are much slower to absorb moisture, and your hygrometer can obviously only read the RH of the air, you will get high readings for a day or two. 90 sounds a bit high, but then I've never used an analog "needle" type hygrometer, perhaps they respond differently than digital.


I would still consider investing in a quality digital hygrometer.
