Aroma & Flavour
Dr. Grinspoon is named after the legendary cannabis advocate Dr. Lester Grinspoon, whose writings — including his seminal book Clearing the Smoke: The Science of Cannabis — fundamentally changed public and scientific assessments of marijuana over the past decades.
This strain is a 100% sativa tribute, producing a powerful, uplifting, and long-lasting high. Its aromas are reminiscent of lemons and the tart notes of sumac, a spice widely used in the Middle East and South Asia.
Visually, Dr. Grinspoon is arguably the most unique sativa on the market. Unlike other cannabis strains, its calyxes grow almost completely separated from one another, giving the plant a structure more reminiscent of a rubber tree than a typical cannabis plant.
The flowers can develop stunning purple hues during the final days of its long flowering period, which spans 90–95 days. Yields are moderate rather than exceptional — those who grow Dr. Grinspoon are chasing quality over quantity, and they are richly rewarded for their patience.
