Our take
Critical Mass CBD is a feminized, indica-dominant photoperiod strain carrying a rare 1:1 THC-to-CBD ratio — roughly 10% of each. That balance makes it a straightforward choice for growers who want something calm and grounding without a heavy psychoactive lean. It's rated beginner-friendly, so first-time cultivators can take it on with confidence.

Growing notes
Critical Mass CBD thrives indoors and out, adapting well to sunny, continental, and Mediterranean climates. It stays short, making it manageable in tents or low-ceiling spaces. Expect a 63-day indoor flowering window and an outdoor harvest around September. Yields can reach 740 g/m² indoors. Feminized seeds mean no time spent identifying and removing male plants — a practical advantage for beginners.
