Chemdawg #4 is not only a legendary medical marijuana strain, but it is recognized for creating some of the finest strains including OG Kush, Auto Oil, Sour Diesel, Stardawg and even BlueChem. Being an indica dominant strain, it has light green buds that are incredibly dense along with large calyxes. However, it is not covered with many hairs but they are visible at the top of the buds and are dark red in color.
