Critical Mass is a combination of Afghani and Skunk #1 that originated from the breeder Mr. Nice Seed Bank. With a large “critical mass” of production, branches tend to snap from the weight of these dense buds. Because the buds are so heavy, the branches of this plant are prone to snapping; thus the “critical mass.” A blend of Afghani and Skunk #1, this strain has a very high THC level—upwards of 22%. That means it’s a powerful experience that is also long lasting in its effects. Ideal for treating stress, depression or even migraines.
