Do I have to use propylene glycol in my humidor?
Simply so, do you need propylene glycol for a humidor?
When your humidor becomes too dry, propylene glycol will release absorbed moisture into the area. However, when there is too much humidity, propylene glycol actually absorbs the excess, keeping the environment stable. You also need to make sure that you check the humidity levels in your humidor every two weeks or so.
Additionally, what is propylene glycol distilled water?
The Activation or Propylene Glycol Solution is a solution that contains a mixture of propylene glycol and distilled water. Propylene glycol is a two-way humidification device that works in two ways: it will both humidify and absorb excess humidity in your humidor. It also acts as a bacterial and mold inhibitor.
Don't be alarmed if your hygrometer reads 80-85 percent humidity. Humidity should normally be only 70 percent, but during the seasoning process, it's normal for it to be higher.
