Critical Mass is a potent indica-dominant hybrid made by crossing Afghani and Skunk #1. In small doses, this strain will have you feeling creative and calm. In large doses, you’ll likely find yourself feeling sleepy and in a couchlock. Critical mass gets its name because of its ability to reach “critical mass” in terms of growing. When growing, branches of this strain tend to snap off from the heavy weight of its buds – which are dense, heavy and tasty.
