I know I'm in the minority here, but I'm not a big fan of beads. They take up a lot of space and are slow to release/absorb moisture.
I use plain old floral foam rectangular humidifiers in my coolers and 100 count, and a Cigar Oasis in each of my wine fridges.
Granted, neither one of them
absorb humidity like beads, but I set the level on the Oasis lower than I actually want it, and when the humidity gets low in the coolers/100 ct I just put a little bit of water in the foam humidifiers instead of soaking them. I'm gonna take a quick peek at my readings.
100 count -- 63% humidity
Cooler #1 -- 66% humidity
Cooler #2 -- 69% humidity (gonna leave it open for a few minutes
)
Fridge #1 -- 62% humidity (Cigar Oasis unplugged for over 1 month now)
Fridge #2 -- 67% humidity (Cigar Oasis unplugged for over 1 month now)
You can get the old school rectangle humidifiers on c bid for $3.
