Hard to say, Andy, but I think that they should be salvageable.

Just recondition the humidor and once it is stable and a few degrees of RH above what you want it to be at, put the sticks back in. The sticks will soak up some of the moisture, so allow for that.

And you really only need a hygrometer, not a hygrostat, as you are measuring only. Salt test it first to make sure you know if there is a delta between the real RH and what your gauge says.
