King Louis XIII, also known as "King Louis," "Louis XIII Kush," and "King Louie" is an indica marijuana strain made by crossing OG Kush with LA Confidential. It's namesake might be most famous for making wigs on men de rigeur for the French aristocracy, but in Southern California the name will bring to mind a popular indica-dominant strain. This strain announces itself as many people did in the 1600s: by its smell.
