Sour Diesel, also known as "Sour D," is a sativa-dominant hybrid strain (70%–90% sativa) renowned for its pungent diesel aroma and energizing effects. It is a cross between Chemdawg 91 and Super Skunk, contributing to its fast-acting, uplifting cerebral effects that enhance focus and creativity. With THC levels ranging from 19% to 26%, Sour Diesel is popular among users seeking a potent head high without the sedative effects typically associated with indica strains.
