I have a 50-60 cigar humidor and am using a small Credo humidification device which got charged up with 50/50 last week. The box sits in my basement office so it rarely is about 73 degrees. The hydrometer in the humi MUST be out of whack since it says 90, I'll test it later with one of the various ways to test an analog device but here's my question,
after not opening it for a while, I opened it up today to notice what could be described as hairs, crystals, ?? on most of the cigars. I know anyhting higher than 65% is a relative no no, but I can't believe it's 90 since I left it out and the room has a 50% level and it still said 60%. Can a small Credo be too much for the box?
