Our take
Critical Auto is a 60% indica-dominant autoflower from Fast Buds that reaches up to 20% THC and finishes from seed to harvest in just 10 weeks — no light-schedule change needed. Its aroma blends lemon, pine, earth, and floral notes into something genuinely pleasant. Straightforward enough for first-time growers, rewarding enough for experienced ones.

Growing notes
Critical Auto suits indoor, outdoor, greenhouse, and mixed-light setups, making it one of the more flexible autos you can run. Expect plants to finish at 35–47 inches, so give them vertical room indoors. The 10-week total cycle keeps your schedule tight and predictable. Outdoor growers can expect 2–5 oz per plant depending on conditions. A solid choice for beginners while still delivering real yields for experienced growers.
