Ah that's odd. I use distilled water with the beads and it works perfectly.I have always used 50/50 mix on foam, which has seemed to work well until this summer when things kept reading 80% no matter what I did. I have never liked plain distilled, one time I used it when the directions said to and kept getting mold. Though the coolerdor is a new thing, I rescued my friend's cigars from beetles while he is on deployment and I put them at my place in a coolerdor so I could keep an eye on it. Temp wise I have never really cared as long as it is below beetle threshold.
@vstromark - I'm really hoping I can make it to the next one.
