Cannabis Trichomes

Bulbous Trichomes – The bulbous trichomes are the smallest trichomes on cannabis which measure normally at 15 to 30 micrometers thus can only be seen with the use of magnifying tools. Their main job is to protect the plant from pests, insects or other elements. They normally start forming when the plant is still young.

Capitate-Sessile – The capitate-sessile are marijuana trichomes with a stem and a globular head. They are more abundant compared to the Bulbous Trichomes and measures normally at 25 to 100 micrometers. They start to appear before the flowering stage and they contain cannabinoids.

Capitate-Stalked – The capitate-stalked are trichomes that can be seen without the use of microscopes or magnifying glass. It also has a stem and a globular head. It is the most numerous trichome found in the cannabis plant. It starts to develop during the flowering stage and measures normally at 50 to 500 micrometers.

The trichomes look like frosty crystals normally clear or milky depending on what stage of its lifecycle it is in. Going in closer using a microscope, the frosty crystals would look a lot like a mushroom with long stems. Some trichomes also look like thorns while some are round. These round type trichomes produce more THC.

Trichomes at Different Stages of the Cannabis Plant

2 to 8 weeks: Vegetative

The bulbous trichomes start to appear at this stage of the growth. These trichomes do not produce cannabinoids and are not seen without the use of microscopes or magnifying glass.

6 to 8 weeks: Flowering

The capitate-stalked trichomes start to appear at this stage of the growth. This trichomes on cannabis produces most of the cannabinoids (THC and CBD).


What do trichomes look like when ready to harvest? Harvesting is the stage when a grower normally uses a microscope or magnifying glass to check how the trichomes look. This process is vital in determining if the plant is ready to be harvested. Normally, a trichome is clear but once it turns to milky or cloudy color means it is ready to harvest trichomes. Why do marijuana trichomes turn amber? If the trichomes started to turn golden or amber trichomes, it means you have missed your window to harvest the plant at its optimum productivity. At this point, the trichomes are already deteriorating and the THC levels are decreasing. The cannabis market is moving very fast as Chuck Rifici, CEO and Chairman of Auxly Cannabis Group has said.
