This cannabis variety was named after Dr. Lester Grinspoon, a scientist, author and advocate of cannabis. Dr. Grinspoon is a pure sativa variety that grows tall and thin. Although the flowering period of this plant lasts longer than other varieties, the mature buds resemble compact green and reddish-brown beads hanging loosely on thin stems. The buds have a lemon aroma and produce a light smoke with tart tropical fruit aromas. The Dr. Grinspoon variety is a typical old school sativa that provides a strong, long lasting, energetic and cerebral effect.
