Having finely ground herbs is a necessity for efficient vaporization. Grinding your dry blend helps to create optimal airflow, which leads to increased vapor production. Whether you’re using a portable or a desktop, it’s always recommended to finely grind dry material before loading it into the unit’s herb chamber. Since vaporizers do not burn herbs, but instead heat them through convection, it’s crucial to grind your dry blend as fine as possible. This will increase heating efficiency and will lead to more active ingredients being released, as well as increased overall vapor production.
