The PG and water create a mixture with separate components. The PG migrates to the surfaces, sealing in the water in a lower layer and therefore takes time for these components to migrate to their proper positions in the oasis and begin regulation. When you install your humidifier, make sure you press firm and hard on the metallic plate for two minutes to assure a tight bond. If this is not done, the humidifier might fall off. Once this is done you can replace the unit and enjoy your smokes.
