Blue Knight, also known as "Blue Night" and "Blueberry Knight," is a rare indica-dominant marijuana strain with a noble lineage that stems from Blueberry and Kryptonite genetics. Hues of royal purple twist with deep blues and vivid greens in a visual display as multifaceted as its berry, vanilla aroma. Earthy, woody, and blueberry flavors are unleashed on the exhale, and the relaxing full-body effects that follow are often enough to soothe pain and stimulate the appetite.
