  • Vaporization

    Vaporization is a method of consuming organic compounds without burning anything. When plant extract is applied directly to a hot enough surface, the liquid in the extract will vaporize on contact. The steam or vapor that's generated allows the extract's organic compounds and flavors to be inhaled and absorbed through the lungs. While vaporization requires higher temperatures than combustion, it's a superior way to consume plant products in the sense that it doesn't create any ash or tar the way traditional smoking does.

  • Plant Matter

    Plant matter refers to raw organic material that's either taken fresh from a plant or dried before use. Ground plant matter is the most common material used with GRAV products, and our bowls are designed to carry a typical serving. Plant matter is consumed by lighting its open surface area with a flame. As it combusts, the plant matter releases organic compounds that can be absorbed through the smoker's lungs.

  • Plant Extract

    Plant extract refers to any product that's created from treating and extracting organic compounds from raw plant matter. Plant extract typically takes the form of an oil or resin, ranging from a soft and waxy consistency to a hard, toffee-like material. Plant extract is consumed by vaporization at a high heat and requires special components to be used with a water pipe or bubbler.
