Runtz is a hybrid marijuana strain and a phenotype of the original Runtz, which crosses Zkittlez with Gelato. The hype around this strain has been firmly established – and for good reason. Runtz features an aroma that is sweet and fruity like candy. This strain produces uplifting effects that are known to be long-lasting. Growers say Runtz is distinguished by an extremely dense bud structure with dark green-to-purple hues.
