Activator Solution For Humidors
Typically a 50/50 solution of propylene glycol and distilled water is used. When making smaller quantities a simple volume measurement can be used.

For the real sticklers in the crowd, when making larger solutions please keep in mind that propylene glycol is slightly heavier than water. Propylene Glycol is 8.61 pounds per gallon while water is 8.34 pounds per gallon. Therefore mixing 1 gallon of Propylene Glycol with 1 Gallon of water will give a 51% solution of propylene glycol.
