Trichome

A trichome is a tiny, hair-like structure on cannabis plants that produces and holds the plant's cannabinoids and terpenes.

Key takeaways:

• Trichomes are crucial for cannabinoid and terpene production.
• They appear as frosty, crystal-like structures on cannabis buds.
• Trichome density can affect the potency and aroma of cannabis.
• They serve as a defence mechanism against pests and environmental stress.

What it is / How it shows up:

Trichomes are commonly mentioned in store menus and product descriptions due to their role in determining cannabis quality. These microscopic structures are found on the surface of cannabis flowers, leaves, and stems. They contain the plant's essential oils, including THC and CBD, and are responsible for the sticky texture and potent aroma of cannabis. Trichomes serve as a protective layer, deterring herbivores and safeguarding the plant from UV rays. The frosty appearance of top-shelf cannabis is often due to a high concentration of trichomes, making them a key factor for consumers looking for potent strains.

How it’s measured or identified:

• Microscope or magnifying glass inspection.
• Visual assessment for density and coverage.
• Lab analysis for cannabinoid content.

Use in context:

• "The trichome-rich bud has a strong, pungent aroma."
• "Trichomes indicate the quality and potency of cannabis."
• "Growers aim for plants with high trichome density."
• "The frosty appearance is a result of dense trichomes."

Safety & compliance in Canada:

• No direct handling required; avoid disrupting trichomes to preserve potency.
• Adhere to Health Canada guidelines for cultivation and consumption.
• Ensure proper labelling of trichome-rich products.

FAQs:

Q: Why are trichomes important in cannabis?
A: Trichomes are vital because they produce and store cannabinoids and terpenes, affecting the potency, aroma, and flavour of the cannabis plant.

Q: How can you tell if a cannabis plant has healthy trichomes?
A: Healthy trichomes appear as clear to milky white hair-like structures. They should cover the buds densely, giving a frosty appearance.

Q: Do trichomes affect the shelf life of cannabis?
A: Yes, trichomes can affect shelf life. Over time, exposure to light and air can degrade the cannabinoids within trichomes, reducing potency.
