King White Willem is a Dutch cannabis strain and White Widow hybrid that has been available in Amsterdam coffeeshops since at least the early 2000s. It inherits its genetics from White Widow — a legendary cross of Brazilian sativa and South Indian indica — and is known for a relaxing yet buzzy, light-headed, and visually stimulating effect. It is considered a medium-strength strain with sweet, floral, and lightly earthy characteristics, popular in the Amsterdam coffee shop scene.
