Critical Mass is an Indica-dominant strain named for the extremely large buds that have been known to snap their own branches in half. This strain has a rather high CBD range of 8%-12%, which is impressive for a strain with such large buds. The combination of Kush and Cola flavors deliver a potent body-numbing buzz that can make users feel lazy and sedated. Most users report this strain brings a clearing of the mind, leaving them feeling creative and focused, yet lethargic. The effects usually last between 2-2.5 hours, depending on the dose. Some users find this strain thought-provoking and nearly psychedelic.

This strain is most often reserved for evening or night-time use due to its sedating effect. For the same reason, it's good for insomniacs seeking a full night's rest. Critical Mass Indica body high may ease most chronic aches and pains as well as relieve stress and anxiety. Others choose this strain for migraines, nausea, and anorexia.

Critical Mass is Mr. Nice's rework of an older set of genetics called Big Bud. The intention behind the rework was to create a stable strain with a massive yield and a very desirable high. It is a cross between a landrace Afghani Indica and Skunk #1. Despite being susceptible to molds and requiring support to grow properly, it is recommended to novice growers because of its yield and ability to grow indoors or out. Reported yields of up to 6 pounds make this strain ideal for cash-crop growers. The strain flowers between 8 and 9 weeks, and it grows well in the Sea of Green setup.
