Our take
Critical Mass CBD Autoflower is a balanced 1:1 THC-to-CBD strain — both sitting at 10% — bred from Critical Mass CBD and ruderalis. That ratio makes it a genuinely different grow from most autoflowers on the market. Indica-dominant and beginner-friendly, it suits growers who want a straightforward plant with a specific chemical profile rather than chasing maximum potency.

Growing notes
This is a good first autoflower. It stays short, so it fits a modest tent or a discreet outdoor spot. The 77-day total cycle means you can run multiple harvests indoors in a single year. It performs well in Mediterranean, continental, and sunny outdoor settings. Expect medium to large buds at medium density. No particular climate stress tolerance is noted, so stable conditions help.
