Dry herb vaping is heating up the herbs to a point that lets the flavors and aromas escape without combustion. And Wax is a form of the herb that is made by pressing the herb and creating a waxy, very condensed oil form.
Dry herb vaporizers have a heating chamber, think of a mini oven. Often, dry herb vaporizers can be used as wax vaporizers as well.
If you use a wax vaporizer with dry herbs, you might combust the herbs quickly, but you get an ePipe kind of functionality.
