Ice Water Extraction
Ice water extraction is a solventless cannabis processing method that uses cold water, ice, and agitation to separate trichome heads from plant material. The technique relies on the mechanical brittleness of frozen trichomes, which detach when cannabis flowers are tumbled in ice-cold water, sinking to the bottom while plant matter floats. The resulting product—commonly called "bubble hash" or "water hash"—collects trichomes at various purity grades based on mesh micron sizes used during collection. This family of extraction methods has become foundational in breeding work focused on trichome density and resin production, since output quality directly reflects plant genetics rather than solvent chemistry.

Breeders working on resin-heavy genetics often evaluate parent lines through ice water extraction to assess trichome yield and quality consistency across generations. This method reveals phenotypic variation in trichome structure and quantity without chemical interference, making it useful for selecting high-resin cultivars in structured breeding programs.
