Heirloom Sativa strain. A strain named in honour of an amazing Cannabis advocate, researcher and author, Dr Lester Grinspoon. This is a pure heirloom Sativa which grows tall and thin. This plant requires a longer flowering time, but when mature the colas resemble compact green and reddish brown beads. These loosely hang on thin stems and are dusted with THC crystals. The buds give a lemon and sumac scent, produce a light smoke with tangy tropical fruit aromas. Dr. Grinspoon offers an old school Sativa of the highest order, which gives a strong, long lasting, energetic and cerebral high.
