Growing Critical Auto (indoor and outdoor)

She is an easy-to-grow autoflowering variety, a cross of Ruderalis, Indica, and Sativa strains. This extraordinary mix produces a vigorous plant with large, dense buds and a heavy Indica effect of the Critical.

Although she is relatively small and stocky, her structure is open, allowing light to reach the entire plant and yields larger and better quality.

Critical Auto does not require much fertilization or extensive care, so it is perfect for inexperienced cannabis growers. It is a very generous plant that grows with strength and remains healthy without requiring special attention.

An increase in soil fertility with a 30% contribution of coconut fibers will be greatly appreciated by this strain which is genetically programmed to start flowering automatically, regardless of light conditions.

Her branches extend both vertically and horizontally, and its few leaves allow good aeration and light penetration, ideal for producing large, beautiful buds. In addition, indoor growers will find the strain easy to manage, as typical indoor heights are only 55 to 65 cm.

The plant produces good yields! Large, dense buds with a sweet, skunk aroma can reach up to 400 to 450 grams per m² indoors and up to 70 to 200 grams per plant outdoors.


Critical Autoflower's high is more bodily than cerebral and provides tremendous muscle relaxation. Often consumed for therapeutic purposes, Auto Critical is an excellent asset in the fight against insomnia, but it is absolutely also ideal for providing a good moment of relaxation. The weed also features a euphoric effect in small doses, while high doses generate complete peace and even some fatigue.

Side effects

Critical Autoflower is a well-balanced strain that results in a nice, smooth smoke. In addition, this strain is not associated with any unpleasant side effects other than the ubiquitous dry eyes and cottonmouth.

Smell and taste
