Willo Hash Rosin

Pressed from hash with heat and pressure instead of solvents, Willo’s hash rosin comes as a 1 g unit, and its strain options include GMO Cookies, labelled indica.

Cold-cured and fully solventless

Rosin is an extract squeezed out with heat and pressure, with no solvent involved, and hash rosin starts from hash, which is the plant’s trichomes, or resin glands, once they have been collected and pressed. Willo’s product page describes this rosin as strain-specific, cold-cured and 100% solventless. Willo presents it as one of the purest concentrate forms of its flower, keeping the aroma, flavour and terpenes of the strain it was made from.

GMO Cookies and Willo’s other rosin strains

Willo gives GMO Cookies an indica label. On its own page, Willo also offers the rosin in Yoda OG and SFV OG, both labelled indica, and in Pineapple Punch, labelled sativa.

Hash rosin is one of several concentrates in Willo’s store, next to live resin, diamonds, THC crumble and shatter, and the Toronto brand says its products are sourced, produced and packaged locally. For how live resin and live rosin differ, see our live resin vs live rosin guide.

Cool, dry storage and a high-THC category

Willo’s storage advice is somewhere cool and dry, away from heat and direct sunlight. In Health Canada’s lower-risk advice, hash, kief, wax and shatter are the examples of high-THC extracts that new or occasional users should avoid, and hash rosin is pressed from the first of them.
