About Critical Mass

History & Genetics

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 THC range of 19%-22%, which is impressive for a strain with such large buds.

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.

Appearance, Aroma, & Flavor

The combination of Kush and Cola flavors delivers 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.

THC Content












The effects usually last between 2-2.5 hours, depending on the dose. Some users find this strain thought-provoking and nearly psychedelic. As nearly all strains with high THC content, this strain when consumed in higher quantities can produce dry mouth and eyes as well as some paranoia and anxiety.

CBD Critical Mass

Be aware, Critical Mass is often more associated with the CBD version of the strain. In some markets, the Critical Mass available from a dispensary will almost always be the CBD-forward run of the strain. The CBD cultivar is notable for retaining much of the bouquet and flavor of the original THC-rich strain, albeit with very low THC (~2-4%) and CBD ranging from 15-25%.

CBD Critical Mass Effects

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.


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 6 and 8 weeks, and it grows well in the Sea of Green setup.

I've grown this cultivar for 2 outdoor seasons and one "up and down" indoor garden and was impressed with every aspect cannabis presents.She likes a lot of room, but you'll appreciate what she'll provide you.

Super stoned. It takes a lot to get me high. I just bought some critical mass prerolls in Denver at 26.2% thc. Definitely has the body mellowing effect. I have super anxiety, but right now, I’m just high as a kite, sitting on my balcony, watching traffic go by, and it’s literally the best thing ever right now. Go get some!
