Bolo 3 (often sold as Bolo Runtz or Bolo Z) is a popular hybrid cannabis strain known for a sweet candy flavor, balanced effects, and high potency. The "3.5g" or "3" in product listings typically refers to an eighth of an ounce (3.5 grams) of flower package size rather than a specific third iteration of the strain. This specific one is a different genetic.
