Humidor in wine cellar

[nutcracker]

So - small problem.

Most of my cigars are in a formal, decent cabinet humidor, and aging happily as pigs in the proverbial.

I do also have a display humidor in my new fancy-schmancy wine cellar. I put a few sticks in to test, as the room is chilly (around 14 deg celsius/ 57 F). The humidity is set at 65%.

Now I realize one can't really age tobacco successfully in a cool environment, but the humidity is an issue, with the sticks are displaying signs of over-humidification (blunderbuss effect on the end and cracking wrappers.) Not good at all!!!

Aside form just abandoning the cabinet, does anyone have any advice? I personally think lowering the humidity to low 60's would be the preferred strategy, but I'm not sure how to even do that.

Regards

Neil
