How are neutral cannabinoids formed?
Through a decarboxylation process during exposure to light, heat, or as a result of prolonged storage.
64
What are trichomes?
Glandular structures that range in width from 10 to 100 µm. Look like shiny, sticky crystals, giving buds their frosty appearance.

What is the function of trichomes?
Defence mechanism
66

Trichomes
67

When the plant enters the flowering stage, just before the buds are ready for harvest

81
Describe THCA crystals
Pure, non-psychoactive compounds until decarboxylated.
82
Describe the process of diamond mining
Resin is placed into containers where it is left to separate for two or three weeks Cannabinoid crystals start to form on the bottom of the container as the solid separate from the terpenes, forming a semi viscous liquid layer on top
83
Describe the common concentration of THCA in diamonds
95 to 98% pure THCA
84
What are some benefits of diamond mining?
High potency Flavourful due to the terpene rich sauce Versatile: can be consumed as concentrates, dabbed, or added to other cannabis products
