Dark Devil Auto by Sweet Seeds

A key differentiator is the color development: Approximately 95% of all units display reddish or purple hues on their flowers and leaves, especially toward the end of the flowering period. This dark appearance is derived from precursors originating from the Chitral region in the Pakistani Hindu Kush. Combined with heavy resin production, this results in a strain that is visually striking and visibly coats nearby leaves with resin.

The effect is described as psychoactive and relaxing. It combines cerebral stimulation with uplifting mental sensations and a gentle physical relaxation. The reported cannabinoid range is 15–20% THC and 0.9% CBD , which positions Dark Devil Auto as a balanced feminized auto variety with a sensory focus.
