What are moon rocks? Moon rocks are made by taking a nugget of marijuana and dipping it in or spraying it with concentrate, or hash oil. The coated nugget is then rolled in kief. Kief, also called pollen or dry sift, is the sticky crystals that cover the cannabis flower. This crystal residue contains terpenes and cannabinoids. Cannabee Extracts is dedicated to producing the finest high quality cannabis extracts, concentrates, oils, and edibles available in Michigan. Our facility uses state of the art technology and decades of combined experience to produce clean and precise concentrates with no impurities or remaining solvents.
