Close up of a Cannabis plant. Cannabis (/ˈkænəbɪs/) is commonly known as marijuana or hemp and has two known strains: Cannabis sativa and Cannabis indica, both of which produce chemicals to deter herbivory. The chemical composition includes specialized terpenes and cannabinoids, mainly tetrahydrocannabinol (THC), and cannabidiol (CBD ...
The plant shows glandular trichomes. They are unicellular, without a specialized basal cell. They have a cutinized cell wall and a protruding pore on the top. The upper part of the trichome cell contains flavonoids, e.g. quercitrin and myricitrin. [9] Epilobium hirsutum seed heads
[24] [25] Further, weed control can be problematic as the stinging nettle has a slow seedling development time. [24] Growing seedlings: For this technique pre-germinated seeds are sown between mid-/end-February and beginning of April and grown in nurseries. Seedlings are grown in tuffs with 3–5 plants/tuff and a seed density of 1.2–1.6 kg ...

A close-up of the flower. The jasmine-flowered nightshade is a woody climber that forms branches 2 to 8 m long and has a base that can reach more than 10 centimeters in diameter. Fast-growing, it climbs by winding the leaf stalks around supports.
Kief (from Arabic كيف kīf, "Joy, pleasure" [1] [2]), sometimes transliterated as keef, also known as "Dust" and "Chief" a.k.a cannabis crystals among other names, refers to the pure and clean collection of loose cannabis trichomes, which are accumulated by being sifted from cannabis flowers or buds with a mesh screen or sieve.
THCA synthase is expressed in the glandular trichomes of Cannabis sativa. THCA synthase may contribute to the self-defense of Cannabis plants by producing THCA and hydrogen peroxide, which are both cytotoxic. Because these products are toxic to the plant, THCA synthase is secreted into the trichome storage cavity. [7]
