Organic Diesel is a potent but mysterious hybrid that leans toward the sativa end of the spectrum. Although it’s clear from the bud’s aroma that it is descended from Diesel varieties, Organic Diesel’s original breeders and exact genetic background are not known. That hasn’t stopped this pungent bud from becoming popular for its easygoing mental high, though. Organic Diesel’s THC content has been measured at levels ranging from 16% to an impressive 28%.
