This top tier strain was created by crossing Chemdawg x Girl scout cookies. GMO stands for “genetically modified organism” or “garlic mushrooms onions” (a reference to its complex aroma). Because of its consistently high THC percentages and incredibly dank terpene profile, GMO has been one of the most potent and highly sought-after strains in the cannabis universe for the past 5 years. GMO has a super pungent nose that is unique to this specific strain.
