Critical Mass Auto brings heavyweight character to a fast, compact grow. Expect dense, crystal-bright buds, a bold citrus-skunk bouquet, and soothing, indica-led effects. From seed to harvest in just 8–10 weeks, it delivers satisfying speed with serious resin production.
Our breeders created this autoflower by crossing Critical Mass with Automatic Reversed, drawing on a rich Afghan Kush and Skunk #1 heritage. The result is an 80% indica, 20% sativa hybrid with robust growth and generous bud formation.
Crack open the flowers and find a vivid mix of lemon and citrus, sweet earth, and pungent skunk. The smoke is smooth and flavorful, with a lively citrus edge over deep, grounded sweetness.
With THC levels around 16–20%, Critical Mass Auto offers a strong, calming body effect. A gentle lift brings happiness and focus, while the indica influence encourages full-body relaxation. It’s a natural fit for unwinding in the evening.
Its terpene profile features limonene, myrcene, linalool, caryophyllene, and alpha- and beta-pinene. Together, they shape its bright, earthy aroma and mellow character. Growers value its abundant resin for flower and concentrate production; consumers often choose this strain for a relaxing finish to the day.
These autoflowering seeds begin flowering automatically, without a light-cycle change. The full life cycle takes 8–10 weeks from germination. Critical Mass Auto is rated suitable for beginners, and every seed comes with Grassfarmer’s germination guarantee.
Start seeds in a quality, well-draining medium such as coco, peat, or soil amended with perlite. Autoflowers benefit from steady care from the start, so avoid setbacks and keep conditions consistent. Indoors, an 18/6 or 20/4 light schedule supports vigorous growth.
Plants are compact and hardy, with a sturdy main stem and branching growth. They can reach around 1.5 m in height and suit indoor gardens as well as sunny outdoor sites. Maintain good airflow, watch humidity as flowering progresses, and provide balanced nutrients throughout the cycle.
In favorable conditions, indoor growers can harvest about 350–400 g/m². Outdoor plants typically produce around 50–100 g each. The quick turnaround makes multiple harvests possible across a suitable growing season, while dense, resin-rich flowers bring the payoff.
