The Rainbow Sherbet strain (or Rainbow Sherbert) is a hybrid cannabis strain, often known for its sweet, fruity flavor and aroma reminiscent of berry and blueberry. It is a cross of Champagne and Blackberry, or sometimes Pink Guava and OZK for a separate but similarly named strain (RS-11). Users report relaxing, euphoric, and uplifting effects, with some suggesting it can aid with sleep, pain, and stress.
