Kief is a concentrated form of cannabis trichomes that contains a high concentration of cannabinoids and terpenes in its tiny, sticky crystals. It is also called "dry sift" or "pollen" and is the cannabis flower's most potent part. Kief is harvested by separating trichomes from the cannabis plant with a grinder or by sifting. It can be added to vape chambers, bowls, or joints for an added kick when your bud is lacking. Kief can also be pressed into hash if you have enough kief in your grinder. Kief is typically more potent than cannabis flower since it's basically pure cannabinoids, terpenes, and flavonoids.
