Hash Literati Handbook of Terminology: Trichomes

Updated: Apr 28, 2021

A working and ongoing terminology and definition list to embolden the writings of hash.

Trichomes are what we harvest for ice water hash. There are three different types of cannabis trichomes:

Bulbous trichomes are tiny bulbs that dot the surface of the plant. They cannot be seen without a microscope and their production of cannabinoids is still in question. They add a sheen to the cannabis plant and add to the stickiness of the flower. Bulbous trichomes are distributed throughout the entire surface of the plant.

Capitate-sessile trichomes are more abundant than bulbous trichomes, but still typically only visible with a microscope. Like bulbous trichomes, capitate-sessile trichomes have large bulbs, but with more of a classic mushroom-shaped structure. This trichome is primarily found on the underside of sugar and fan leaves.

Capitate-stalked trichomes are the ones we're after. Shaped like mushrooms and containing a large bulb or "head" at the top of a stalk. These are the largest and most abundant trichomes on cannabis, (yes!) and most familiar to consumers. The capitate-stalked trichomes are primarily found on the surface of cannabis flowers and are rarely seen on fan leaves or stems.

Cannabinoids, terpenes, and flavonoids are produced within the trichome cells through biosynthesis. The psychoactive effects of cannabis are determined by the combination of terpenes and cannabinoids contained within these trichome glands, to the best of our understanding.

Smoking Hash (trichome heads)

Since the entire trichome gland is preserved, it will leave a bit more behind, but it's worth it. This is caused by the thin outer layer that contains each individual trichome. Rosin removes these outer layers to provide only the inside of each trichome, but loses the most volatile terpenes at the same time. There is some give and take with either method, but the best ice water hash should melt clean, leaving very little behind.

Dab at about 500 degrees or just under, and allow the hash to slide off your tool - usually

onto the sides of your banger, in globs or
