Temperature and Humidity

I use a wine fridge but my concern is humidity control.

I may have found a solution by adding some “humidity beads” made to control humidity in cigar cabinets.

These crystals absorb humidity if it is too high and provide humidity when too low, they are made to preserve humidity at about 70%.

They are cheap and may be set in a nylon stocking or in any dish at the bottom of the fridge, they work with distilled water and are cheap.
I bought them at cheaphumidors.

My question is: is 70% humidity correct for a drying chamber?
