Chem 91, also known simply as “91 Chemdawg,” is an evenly balanced hybrid strain often said to be the parent or family of the infamous Chemdawg strain. Like the name suggests, this bud has a powerful flavor of chemicals topped with earthy diesel and lemony pine. The aroma is even more pungent, with dank diesel and pungent earth mixed with a sharp skunkiness that will fill any room.
