We have a small house and a lot of stuff (camping gear, winter coats, books) is kept in a storage facility. The place we had first was very humid, then I bought a hygrometer and found another space.
The hygrometer measured 80% humidity in the new place when I left it on the floor, which is just tarmac. I though that this is too humid to move there. Is it wrong to put it on the floor and should I instead have put it on something?
Then I found yet another space, moved stuff from the original humid storage to the new place which is on the first floor of an unheated storage facility. This time the hygrometer read 75%. This reading is also from the floor and I had filled the space with stuff coming from the original storage. I have no reading for the humidity there but I did hang a cotton bag with about 1.5kilo of salt there, and it was dripping.
Is it possible the humidity at the newest place is in fact from my stuff, and the storage itself would be ok? Is it wise to put the hygrometer on the floor?
