23 reviews
Critical Mass was created by Shantibaba of Mr. Nice Seeds as a high-yield commercial indica. Named for the sheer weight of its buds — so heavy that branches can break without support — it became the defining commercial yield strain of the early 2000s and remains a benchmark for high-production grows.
