Northern Jack Autoflower Feminized Cannabis Seeds

Genetics & strain profile

Northern Jack Autoflower is a feminized autoflowering strain bred by Quebec Cannabis Seeds. It comes from a Northern Lights and Big Bud female auto crossed with BigJack, a Jack Herer and White Widow male auto. It is a 50/50 hybrid with high THC and low CBD. The page gives no THC percentage, so we will not guess one, and the page describes it as a medium-height autoflower. The page gives no difficulty rating or beginner badge, so first-time growers may prefer a strain that has one.

It has no reviews yet, so what you read here comes from the breeder’s description and not from customer grows, and we will not claim results beyond that. 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 Northern Jack 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 flowers in 6 to 8 weeks. The page gives no seed-to-harvest total, so do not plan around the flowering figure alone. The plant is medium in height. Yields are around 300 to 450 g/m² indoors in good conditions and about 200 to 450 g per plant outdoors; the outdoor range is wide, so plan around the lower number.

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. It is listed in our October harvest category. Yields are best cases under good conditions, not promises. Check your local rules before you plant.

Taste, aroma and effect

Fresh herbal notes with earthy depth, and a brighter, spicier lift from the Jack Herer side. The effect is well rounded: upbeat at first, then more settled and comfortable. As the page gives no THC percentage, 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. For related autoflowers, see OG Jack Autoflower, Jack Afghan Autoflower and Emperor Jack Autoflower.
