Dark Knight is an indica-dominant hybrid. It’s a cross of Granddaddy Purps (GDP) and Purple Kush.  Users report a strong body buzz with a happy mood that’s good for treating depression, insomnia, anxiety, and chronic pain. This can be a highly effective treatment for paediatric seizure disorders and other conditions that respond to CBD. Dark Knight is an obvious homage to the Christopher Nolan Batman trilogy, but its exact origins are unclear. It’s definitely not a well-known strain, but can probably be found in select dispensaries on the West Coast.
