Cannapedia Encyclopedia of cannabis strains


A trichome is defined by dictionaries as “subtle outgrowth on a plant, an alga, a lichen, or certain kinds of protozoa”. The name comes from a Greek expression tríchōma, which roughly means “growing hair”.

These microscopic mushroom-like outgrowths resemble aliens from a sci-fi novel, but they are, in fact, tiny factories that contain dozens of known cannabinoids, terpenes and flavonoids. Our favorite strains are so potent, unique and effective only thanks to them.

Trichome formation happens in many kinds of plants in nature with various differences in both their form and purpose. Trichomes of carnivorous plants can, for example, help them entrap their prey.

When it comes to cannabis, trichomes work as plant’s main defense system against all enemies – living or other. When female cannabis plants start forming buds, they are often defenseless against many insects and animals found in nature. They can be threatened even by the potentially dangerous UV rays. Luckily enough, the bitter taste and strong smell of trichomes repel all animals away from precious buds.

Trichomes come in many shapes and sizes, but there are three most distinguished types that are commonly found in all cannabis plants.

  1. Bulbous are the smallest ones and they occur all around the body of a plant. They are only 10-15 micrometers in size and consist of only a few cells.
  2. Capitate-sessile are slightly bigger. They consist of a head and a stem.
  3. Capitate-stalked reach up to 150-500 micrometers, meaning they are way bigger and can be observed with a naked eye. They consist of a stem with epidermal and subcutaneous outgrowths and a big gland head with an attached basal cell.
