Sour Jack, one-half Sour Diesel one-half and Jack Herer, takes its name from its parents. It has developed a solid reputation and is highlighted by an intense aroma and profound cerebral effects. After combining the two sativa-dominant strains, we are left with an amazing combination of tropical, sweet flavors that mix with pungent tones of citrus and diesel. The uplifting effects can provide a spark of energy and minimize body fatigue. Sour Jack is a great strain to fight off depression and to help you stay active.
