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. Flowering time is approximately 6-8 weeks, with a heavy leaf to flower ratio. However, due to the large production of flowering, this strain is susceptible to mold which can be reduced by growing indoors to reduce humidity. THC levels of this strain may reach 19-22%.
