No, the strain GMO Cookies is not a genetically modified organism but a cross between Chemdawg D and a GSC (formerly Girl Scout Cookies) Forum cut. Also know as GMO or Garlic Cookies, GMO Cookies has been attributed to the breeder Mamiko Seeds, but this skunky phenotype has also been said to have been discovered by a breeder named skunkmasterflex.
While Mamiko seems to have called it just GMO, dispensaries were understandably wary of having that “GMO” label on their shelves and went with Garlic Cookies instead. GMO Cookies is said to carry a flavor of garlic, mushroom, and onion that descends from its Chemdawg lineage.
Divine Genetics also has a strain that’s a cross of Chemdawg #4 and GSC that it calls Chem Cookies. Despite the similar genetics, it appears to be a different strain with different phenotypes for both parents, although it’s worth noting that some people do confuse two strains. GMO Cookies is said to produce olive green buds with bits of purple and orange blanketed by a mantle of trichomes.
Neither seeds or clones of GMO Cookies appear to be available online, but some cultivators possiblymay be able to get a clone from someone. The only grow data available online claims that this cultivar is moderately difficult to grow, but there aren’t many sources offering more information.
