Trichomes: Trichomes are defined as “fine outgrowths or appendages on plants, algae, lichen and certain protists.” They are classified into three different groups: bulbous, capitate and non-glandular and resemble small, microscopic mushrooms. Bulbous and capitate trichomes are the tiny factories where the cannabinoids, terpenes and flavonoids are produced. The resin produced from trichomes is also what protects hemp flowers from the sun’s ultraviolet rays, water loss and insects and other predators.
