Frost Coverage

Frost coverage refers to the visible accumulation of trichomes—crystalline resin glands—across cannabis flower surfaces, creating a white or silvery appearance often described as "frosty." This trait results from dense trichome production rather than a specific terpene, though certain volatile compounds are frequently co-expressed in heavily trichomed varieties. Breeders have selectively developed lines exhibiting pronounced frost coverage for several generations, with lineage records frequently reporting this trait in Kush, OG, and Gelato family genetics. High trichome density correlates with resin accumulation but does not directly indicate potency or specific flavor profiles. Frost coverage serves as a visual marker in breeding programs and plant selection, though appearance alone does not determine chemical composition or cultivation outcomes.

Cannabis breeders prioritize frost coverage as a desirable phenotypic trait during selection rounds, often crossing parent plants exhibiting dense trichome expression. Growers and breeders use observable frost development as one criterion among many when evaluating phenotypes for stability, consistency, and market presentation.
