Critical Mass

Critical Mass is an indica-dominant hybrid known for its exceptionally large and dense buds, which can grow so heavy that they may break the branches. Despite the size of its buds, Critical Mass boasts a relatively high THC content. This strain is particularly valued for its calming, sedative effects, making it popular among users seeking relief from chronic pain, stress, and insomnia.

Additionally, Critical Mass is better suited for indoor cultivation, as its massive buds are prone to mold when grown outdoors.

This strain was developed by Mr. Nice Seedbank, a reputable breeder with multiple High Times Cannabis Cup wins. It was created by crossing Afghani indica with Skunk #1 and has a genetic makeup that is 80% indica and 20% sativa.

The average THC content of Critical Mass is around 20%, while CBD levels are generally low, with certain phenotypes reaching up to 5%. The strain's high yield and occasional high-CBD phenotypes have made it a foundation for many breeding projects. A CBD-rich variant called "CBD Critical Mass" is also available, featuring a balanced 1:1 THC to CBD ratio, typically ranging from 5% to 10% of each.

Dosing

While Critical Mass can provide temporary relief from stress and anxiety, overuse may lead to the opposite effect. Its sedative terpenes, like myrcene, pinene, and humulene, make it an ideal choice for nighttime use when relaxation and sleep are the goals.

Growing

As an indica-dominant strain, Critical Mass grows short and bushy, making it ideal for indoor cultivation. It is susceptible to mold due to its dense buds, especially when grown outdoors in humid conditions. Indoor growth allows for better control over humidity and temperature, which is crucial for preventing mold development.

If you grow Critical Mass indoors, remember to provide the plant with regular feeding, water, and sun. Also — this can’t be stressed enough — stay on top of the humidity and temperature to prevent mold from growing on the buds.

Height

Critical Mass grows between 32-80 inches (1.1-2 meters).

Humidity and Temperature

Keep humidity at around 50% during the vegetative stage and reduce it to 30%-35% during flowering. Ideal daytime temperatures are 68-80°F (20-26.7°C), with nighttime temperatures no lower than 60°F (15.5°C).

Flowering

The time for Critical Mass to flower is eight weeks or longer. Most indicas typically finish flowering in about six to nine weeks.
