Just got a new humidor a month ago, prepared it for a week using distilled water in a dish for 7 days. So for the last 3 weeks with cigars in it stays at 80 humidity with the foam humidor with 50/50 solution. Get it to 70 leaving the lid open then goes back to 80, any ideas.
On another subject I remember having humidors in the 1980's where the humidifier was a clay ? Bar , what ever happened to these.
