Pronounced “try-combs,” these are the tiny, crystal-like, mushroom-shaped glands that cover the surface of cannabis flower. They are the microscopic factories that produce and store the plant’s cannabinoids (like THC and CBD), terpenes, and flavonoids. When you see a frosty, sparkling layer on a high-quality nug, you’re looking at a dense field of trichomes. In essence, they are the source of both the psychoactive effects and the unique aroma and flavor of a strain. Protecting them during storage and handling is the key to preserving the full potential of your herb.
