What are Cannabis Trichomes?

Trichomes are resin glands of the cannabis plant that also serves as one of the many indications to physically determine whether a certain cannabis plant is highly potent or not. Those trichomes appear as tiny hair-like in gray or crystal clear appearance that makes the plant appear more stellar.

Those tiny hair-like glands are the basis of the breakthrough in the use of cannabis for medicinal purposes. The well-known case study of Charlotte Figi who was cured of seizures with a tincture of trichomes from a CBD-rich cannabis strain which is now called Charlotte’s Web was named after the girl.

In cannabis plants, trichomes start to develop when the plant enters its flowering phase. When cannabis buds start to develop, trichomes begin to form in their flowers, leaves, and stalks. It helps cannabis growers timely determine the perfect time to harvest.

Aside from being an aesthetic addition to its overall appearance, trichomes also serve to the protection of the plant from many environmental risks. The more trichomes there are in a cannabis plant, the more resilient and adaptable that strain is.

Different Types of Cannabis Trichomes

Trichomes differ in type, structure, and size. In cannabis plants, there are three main types of trichomes that can be found. These categories can be divided into two parts.

  • Non-glandular Trichomes

Non-glandular trichomes are a type of plant trichomes that does not have glandular heads. It can be unicellular or multi-cellular. It can be branched or unbranched. Most of the non-glandular trichomes are simple, branched essential, and star-shaped.

  • Glandular Trichomes

The main thing that distinguishes between these two types of trichomes is their ability to produce cannabinoids and terpenes. Cannabis plants with glandular trichomes are often used as components in making essential oils, beauty cosmetics, and even in alternative health.

  • Bulbous Trichomes

Bulbous trichomes are hard to spot using our eyes only. Despite them being located on almost the entire surface of your cannabis plant, it takes the help of an advanced tool like a microscope to fully appreciate their appearance.

  • Capitate-Sessile Trichomes

Compared with the Bulbous trichomes, this type has a larger size, however, you will still be needing at least a magnifying glass to fully apprehend its appearance. Just like the Bulbous trichomes, capitate-sessile trichomes are abundant in the cannabis plant’s surface but the only difference is that it contains cannabinoids.

  • Capitate-Stalked Trichomes

Just like the capitate-sessile trichomes, this type contains cannabinoids but more than what the first can offer. Furthermore, unlike the first two types which need tools to spot their appearance, capitate-stalked trichomes can be visibly seen without using any microscope or magnifying glass.

What is the purpose of  Cannabis Trichomes?

Cannabis trichomes offer various functions. It protects the cannabis plant from harmful UV rays, strong weather conditions, and fungal spores.

The number of capitate-stalked trichomes on the surface of cannabis plants grows in number during its flowering stage. Before this, cannabis plants are mostly covered with bulbous trichomes and capitate-sessile trichomes.

As soon as your cannabis plant starts to mature, trichomes will start to be more visible on its surface. While other types of trichomes are more likely to develop earlier than capitate-stalked trichomes, they are not easy to spot without the use of tools like microscopes or magnifying glasses.

In other cases, trichomes can be removed if you prefer to get extracts such as essential oils, wax, hash, or shatter. Other than that, trichomes also serve as indicators for cannabis growers. It acts as a signpost that tells you when cannabis plants are ready to harvest.

Trichomes change in color. However, such changes may not be visible to your naked eye. A little help with tools like a magnifying glass will better help you determine the accurate signs.

When terpenes turned from clear to cloudy, this indicates that the cannabis plant is ready to harvest. If you wait a little longer, the THC level will convert into cannabinol which causes it to turn to amber.

Most cannabis growers tend to wait for it to turn to amber. This will transform the buds with a perfect mix of THC and cannabinol which provides more potent effects.

How do Cannabis Trichomes work?

The main role of trichomes in every cannabis plant is to produce cannabinoids and to do this, it first needs to generate the production of CBGA which is considered to be the mother of all other cannabinoids. When the CBGA is finally produced, it maximizes your cannabis plant’s energy to produce more cannabinoids like THCA, CBDA, and CBCA, which later transform into THC, CBD, and CBC.

Cannabis trichomes are volatile and can be easily affected by heat, light, oxygen levels, age, and physical contact. Thus keeping your buds under direct sunlight for long periods may affect their quality and density.
