Critical Mass is a combination of Afghanistan and Skunk # 1 derived from the breeder M. Nice Seed Bank. When the “critical mass” of production is important, the branches tend to detach themselves from the weight of these dense buds. The flowering period is about 6 to 8 weeks, and there is a ratio of leaves and thick flowers. However, because of the large amount of floral production, this strain is susceptible to mold and moisture can be reduced by growing indoors. The THC level of this strain can reach 19-22%.
