Dr. Grinspoon, I presume? back in the ’70’s Harvard prof and cannabis advocate Dr Lester Grinspoon tried to enlighten the world about the benefits of this miracle plant. And while the world wasn’t ready to listen, Barney’s farm in Amsterdam was, creating this pure sativa heirloom in his honor. Dr Grinspoon grows like berries on branches in popcorn clusters. Its unusual structure yields smallish harvests after a three-month flowering cycle. Indoors is best for growers whose patience and time pays off handsomely with frosted buds that will dazzle even the most seasoned users. Earthy, honeyed flavors with peppery notes enhance the exhilarating, mood-boosting, and all-round fabulousness of this iconic sativa.
