Glossary: Industry Terms


Circulation of fresh air, fundamental to a healthy indoor garden, an exhaust fan creates ventilation.


A soil amendment and medium for root cuttings, vermiculite is a hydrous phyllosilicate mineral and it undergoes significant expansion when heated. Exfoliation occurs when the mineral is heated sufficiently, and the effect is routinely produced in commercial furnaces. Vermiculite is formed by weathering or hydrothermal alteration of biotite or phlogopite

Vitamin B1

Vitamin that is absorbed by tender root hairs, easing transplant wilt and shock.


Washing Machine

A tool for making bubble hash that mechanically mixes the cannabis and ice mixture.

Water Hash

Also known as ice water hash or bubble hash, is a specific technique to separate Tetrahydrocannabinol (or THC) trichomes to isolate the resin in cannabis. Using micro screens, ice, and water, one can effectively strain out resin glands that are inherently more dense than water. Large quantities of pure resin can be removed from the plant material, water ice water separation is a cleaner method that doesn’t involve other solvents and allows for a more refined hashish.

Water Table

It refers to the underground surface within which the soil is saturated with water and optimum soil-air environment conditions should be maintained within the root zone in order to achieve good crop yields.


It is a general term used to refer to extracts that are solid, opaque and with a soft texture. In its preparation, cannabis buds are packed tightly into a tube and then blasted with butane (a highly flammable liquid) that separates the trichomes from the material resulting in a concentrated substance. It is available in different consistencies and variations like honeycomb, crumble, earwax, sugar etc. with the difference arising from the extraction and purging process used in each variety’s production. 

Waxes and Lipid Fats

Naturally occurring substances found within the cannabis plant; waxes and lipid fats are often removed during shatter concentrate production.


Another slang term for cannabis and it’s frequently used, specifically in reference to flower.

Wetting Agent

A compound that reduces the droplet size and lowers the surface tension of the water, making it wetter, so a liquid concentrate dish soap is a good wetting agent if it is biodegradable.
