Black Dog by Humboldt Seed Organization is a weighty mixture of two northern California favorites, Blackberry Kush and Emerald Headband. This medium-sized plant expresses dark, nearly black leaves that give way to sticky, dense buds. Its aroma is a mixture of grape, berries, and oil while the effects tend to be relaxing with just a touch of cerebral stimulation. Black Dog has a rapid flowering time of 48-55 days.
