Critical Mass has a very nice plant metabolism and structure, resulting in very frosty and dense buds with a sharp flavor. Critical Mass is a reworked excellent version of an old breed once known as Big Bud. This is a large yielding strain with an equally high stone. Critical Mass is a heavy plant currently in production both indoors and outdoors with massive buds.It's genetics originate from a very heavy Afghani combined with the original Skunk #1. Critical Mass is a favorite plant of many growers looking for a huge yielding potent strong plant. 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 up to 24%.
