Origin
Critical Mass is a selected, stabilized version of Big Bud, which itself came from Afghani crossed with Skunk Number 1. It was bred down for even bigger yields and a heavy indica effect. It has eight descendants on file and is a common breeding parent. Its value is the yield it passes on, more than anything about the smoke.
Advanced Seeds's record agrees with 8 other breeders: Aficionado Seed Bank, Amsterdam Genetics, Bulk Seed Bank, Hempire Seeds co., Linda Seeds, Quebec Cannabis Seeds and 2 more.
2 lineage claim sets recorded. The one shown is attributed to Advanced Seeds; the others are in the tabs above, each with its own source.

The difficulty to grow Critical Mass is known for being easy. For growers cultivating indoors, expect average height with a 650-750g/m yield with in about 6–8 wk. Outdoors, harvest around September.
Cultivation Notes
Critical Mass yields 650 to 750 grams a square meter indoors and 500 to 600 a plant outdoors, ready in September. The buds are dense enough to snap branches, so plants need support, and it is prone to mold in humid conditions. Height is not recorded. Figures are grower and breeder reported.

About
Critical Mass grows buds so heavy they snap their own branches.
It comes from Big Bud, itself an Afghani and Skunk cross, selected hard for yield. THC sits around 20 percent, sometimes with a notable CBD reading, and the effect is a heavy, sedating body high. It is a grower's strain first.
Yield is the whole point.
What to Expect
Critical Mass is a heavy, sedating body high best kept for the evening. Leafly's reviewers lead with relaxed at 69 percent of a solid sample, with happiness and a euphoric lift behind it and sleepiness at 36. Several sources describe a clearing of the mind before the body sinks.
Dry mouth leads the negatives at 30 percent, with dry eyes at 17 and the sharper notes low. A moderate dose is enough given how sedating it gets. It is a nighttime strain.
Flavor and Aroma
Critical Mass is a pungent, sweet, earthy smell, strong on the plant and milder once smoked. The flavor runs sweet and piney with a citrus and skunk edge over earth. It is a classic skunk-and-Kush profile.
Terpenes Explained
Critical Mass has only a token terpene reading in our data, with Humulene, Myrcene, Caryophyllene and Pinene all logged at trace levels and Limonene unmeasured.
Those numbers are too low to be a real profile, so the pungent, sweet smell has to be judged by nose. A jar with a strong sweet-skunk aroma, mild once ground, is true to type.
Cannabinoids and Potency
Critical Mass THC is reported from about 19 to 22 percent, solid, with no clean lab sample in our data. Some readings show a CBD level as high as five percent, though most are lower. Expect a strong indica.
Critical Mass tests around 20 percent THC, sometimes with real CBD, so it can hit a little rounder than a pure THC strain.
