This is a collection of trichomes that are sifted from the cannabis flower or bud. This is the most potent part of the cannabis flower and contains a high concentration of cannabinoids and terpenes.Dry sift, commonly known as kief, is a solventless concentrate known for its versatility and potency. 
It is made by rubbing or agitating cannabis plant matter on screens or sieves. This process strips the plant matter, leaving behind a collection of the resinous trichome glands of the plant. 
Trichomes contain cannabinoids, terpenes, and flavonoids that contribute to the plant's psychoactive effects and medicinal benefits. When collected through dry sifting, they look like a powdery substance. 
Tetrahydrocannabinol (THC) is one of the most abundant cannabinoids found in dry sift, which is why consumers sprinkle it on top of a bowl or add it to a joint to increase potency. 
You can also use dry sift to create Moon Rocks or infuse edibles. Hash heads can hand-press dry sift to create hash bars.
