"Doesn t seem to do the trick"
Thought I would try these to get a little more stability in my humidor. My recently purchased humidor sometimes creeps up to the 73-75 RH level with the green foam humidifier it came with. When I use the Xikar jar it slowly creeps back down... and down... and down to the low 60s until I have to go back to the green foam. I ve tried using multiple jars on two levels since my 100 ct humidor has a removable shelf and still the same thing.
