GMO candy strain" can refer to a few different strains, but likely points to a cross of the popular GMO (Garlic Cookies) with another strain that includes the word "candy" in its name, such as Candy Rain or Candyland. These strains are typically indica-dominant hybrids known for their potent, relaxing, and euphoric effects, and a flavor profile that combines the signature garlic/gas notes of GMO with the sweetness of their candy lineage.
