Critical x Northern Lights Autoflower Cannabis Seeds Feminized

Genetics & strain profile

Critical x Northern Lights Autoflower is a feminized autoflowering strain bred by Quebec Cannabis Seeds. It comes from Critical and Northern Light Auto. It is mostly indica with 19 to 23% THC, and the page describes it as easy to grow, for novices and experienced growers alike. It carries our beginner-friendly and compact, balcony-friendly badges.

It has two reviews, both five stars. One reviewer describes solid, very frosty flowers and mentions receiving two free seeds; the other reports that every seed germinated, with fast growth and normal cotyledons. Two reviews is a small sample, so treat them as encouraging, not conclusive. Autoflowers are forgiving, but forgiving is not the same as maintenance-free: water and feed with care and check the plants regularly. Our seeds are guaranteed, so if a seed does not come up, contact us.

How Critical x Northern Lights Autoflower grows

Because it is an autoflower, it flowers on its own schedule without a change in light hours, so you can run the same long-day lighting from start to finish. It is ready 70 days from seed. The plant stays compact, which suits indoor spaces, and it also does well outdoors. Critical brings fast flowering, sturdy growth and high yield, and Northern Lights brings its relaxing effect and resilience. It gives up to 450 g/m² indoors; the page gives no outdoor figure.

Sow directly into the final pot, because autoflowers dislike being transplanted, and keep the medium damp but not soaked at about 22 to 25 °C until the seedling breaks the surface. Keep the room steady, with consistent temperature and humidity, because stress can slow an autoflower and cut the yield. Water gently, feed lightly and harvest by the trichomes rather than by the calendar. Outdoors, sow after the last frost so the plant has the whole warm season. Yields are best cases under good conditions, not promises. Check your local rules before you plant.

Taste, aroma and effect

Earthy and sweet, with hints of pine and citrus. The effect is physically relaxing, with a touch of uplifting euphoria. At 19 to 23% THC, newer consumers should start with a small amount, since effects vary from person to person. Any flowering cannabis gives off a smell, so plan for odour control indoors.
