I had to move my electric humidor into my home office. Its a small room and gets hot in the winter. Baseboard heating. So, the RH became harder to manage with just Bovedas. I went from 62 to 69% packs and it was still low. I switched to the HumiCare Gel bottles (3 of them!)...still could not get the RH to stay around 65% which is my sweet spot.
Finally got a Xikar Gel thing, filled with Propylene, and also added a shot glass of DW and RH is rock solid at 64-65%
I get that the dry heat in the room was the cause, but why did all these other things not work and a glass of DW did the trick?

very interesting. Thanks Puffy

Puff explain how you did that in terms I can understand. I’ve got a large 70 bottle wine fridge I converted. It’s ok with just boveda but I’d like the whole system to be more stable top to bottom. It’s almost as tall as a refrigerator. So my humidity varies. I basically use it as storage.

I would start with running a reptile humidifier or a fridgador humi and run that bad dog on low with just the furniture and humi in the fridge. Get it settled at 83% RH for about 3 weeks, considering the size. Then step it down to your RH about 1-2% per day. I'd place twice as many beads at the top as the bottom with a fresh water source in the middle. Then monitor it. That CF, I'd try 20-30 rolls at time while monitoring the humidity. I know the old 70&70, but I like to make it complicated with 65F and 62% RH. If your unit has vent ports, I'd go with an entirely different system. And being that large of a capacity, it just might for cork health.
