Mold, mold. Mold... And your sticks will taste like bitter wet logs...
Gel humidifiers give off excessive amounts of moisture... But the do no absorb any.. In many peoples opinion they are junk.
Put your sticks in a sealed Tupperware and then open your humidor to bring RH down.
Get some 65rh boveda packs.... Once your humidor stabilizes at 65 you can add the sticks back.
