Kief
Kief is the collection of trichomes (resinous glands) that separate from cannabis flower, typically collected in the bottom chamber of a grinder. It appears as a fine, powdery, golden-green substance and contains a concentrated amount of cannabinoids and terpenes. Kief can be sprinkled on flower, pressed into hash, or used to make edibles. It is one of the simplest forms of cannabis concentrate.
