Hash (also known as "hashish") is a concentrate made of the plant's resin glands, called trichomes, separated from the plant and gathered or pressed together. Trichomes are tiny, mushroom-shaped glands on the flower where the plant makes and stores cannabinoids and terpenes. The separation is mechanical (dry sifting, ice water, or hand rubbing), so it uses no chemical solvent.

Kief is the loose trichomes that fall off dried cannabis. It is the fine powder that collects in the bottom of a grinder. Dry sift is kief made on purpose: dried, often frozen, cannabis is gently rubbed or tumbled over fine mesh screens, and the resin passes through finer and finer screens, leaving plant particles behind. No water or solvent is used.

Quality depends on how much plant material remains: Unrefined kief is greenish and less potent than refined dry sift, which is blonde to tan, much stronger, and, at its best, reaches full-melt grade. Sprinkle kief and dry sift on flower, use them in infused pre-rolls, or press them into hash or rosin.

A plant bred from both indica-type and sativa-type parents. Menus use "Hybrid" for effects described as in between or mixed. The label is often narrowed to indica-dominant hybrid, sativa-dominant hybrid, or balanced ("50/50"). Any percentages given are the breeder's estimate from the plant's family tree, not a measured one.

After decades of crossbreeding, nearly all modern commercial strains are hybrids in the genetic sense, regardless of the label they carry. The label says more about how a product is positioned than about the plant. A listed lineage (the cross) is more specific, but a strain name doesn't guarantee chemistry either.
