To maintain proper humidification
in your humidor, moisten the humidifier (humistat) - a
sponge type of material in a vented case which mounts to some part of the humidor
(usually the lid) - initially with a 50/50 mixture of 50% distilled water and 50% PG
(propylene glycol) then monthly or as needed with distilled water. A ready made mixture,
Griffo Solution ™ is also available.
