What Are Trichomes?

Trichomes are epidermal outgrowths, glandular surface hairs that produce, in the case of cannabis, a broad range of cannabinoids. This is also how mint leaves make and store their mint oil. Cannabis trichomes produce and house not only THC but hundreds of other medicinally valuable compounds.

For some carnivorous plants, their trichomes help them catch prey. For cannabis, its trichomes protect the plant acting as a natural bug and animal repellant while shielding the plant further from wind, UV rays and some bacteria. This is similar to coffee where caffeine, the part we're after, is actually the plant's natural bug repellant.

Different Types

Bulbous trichomes, as small as 10-15 micrometers, are the smallest type and appear all over the plant surface. Capitate sessile trichomes are a bit bigger and have both a head and a stalk. Capitate-stalked trichomes, as large as 50-100 micrometers, can be seen by the naked eye. They have a head, a stalk and gland head which is where cannabinoids and terpenoids are synthesized. All three types make cannabinoids but the Capitate-stalked produces highest concentration of essential oils.

Bloom With Light

As the cannabis plant begins to flower, trichomes appear all along the surface. With further growth and time, the gland heads start to metabolize cannabinoids.

Type and concentration of cannabinoids depends on, like wine, genetics and environmental factors. These include not only the amount of light but the spectrum or type of light. Typically, plants that receive a broader spectrum of light will produce higher concentrations of cannabinoids, though results and reactions are strain-specific.

MATURATION

As the trichomes mature they change in opacity from clear translucent to cloudy white to an amber hue. This head color transition shows ripeness and farmers use this as a sign to harvest. While all strains mature at different rates, this coloration remains the standard to indicate trichome progression and alert from degradation.

Extraction

Trichomes are extracted from the plant by a few methods and techniques. Dry sifting produces kief. Chemical extractions using hydrocarbons create waxy oils. If extracted correctly, these valuable cannabinoid-rich trichomes can be stored indefinitely.

PARTICIPATE

The tide is turning. A majority of Americans think cannabis should be legal and our laws, state by state, are starting to accomplish this. But millions are still denied access, or languish in prisons, due to antiquated laws that hurt rather than help us.

Do your part to help these fellow citizens and show the world how cannabis should be managed, with education, understanding and compassion:

  • Support The Ending Marijuana Prohibition Act of 2017 and/or The Marijuana Justice Act of 2017
  • Ask Your Congressional Representative To Join the Cannabis Caucus
  • Support the Amendment To Expand Veterans’ Access to Medical Marijuana
