I recently purchased a set of Naniwa Pro stones and got into sharpening.
After my first sharpening session I left the stones to dry (what I thought was touch dry) and then placed them back in their cardboard boxes they came in, and stored everything in a plastic seeled box.
A month later there was Mould on at least the flattening stone box and very slight dampness on the others. Obviously the stones, although touch dry, had retained their moisture.
So how do you store whetstone?
