Headbanger (also called Headbanger Kush) is a cross between Sour Diesel and Biker Kush, grown by the team at Karma Genetics. While reportedly known as a “creeper” strain, Headbanger provides users with an energetic joy similar to headbangers at a thrasher metal concert. The strain smells of a pine forest with matching earthen flavors and a hint of sour-sweet berry.
