Despite having “Cookies” in its name, Garlic Cookies, or GMO, is one of the only strains on this list without a sweet aroma. This strain reeks of garlic and gas. Its presence here is proof that the once-popular loud, gassy strains have not been entirely left in the past. SkunkMasterFlex of Skunkhouse Genetics created the strain with a seed, labeled “Chem D x GSC,” bred by Mamiko Seeds. According to SkunkMasterFlex, the name “GMO” came after the revelation that GMOs were used in the cookies from the Girl Scouts of America. It also hints at how the strain grows as if it were genetically modified.
