OG Jack Autoflower Feminized Cannabis Seeds

Genetics & strain profile

OG Jack Autoflower is a feminized autoflowering strain bred by Quebec Cannabis Seeds. It comes from Jack Herer and OG Kush, crossed with Ruderalis. It is 60% sativa and 40% indica with 19 to 23% THC, and the page describes it as easy to grow, even for beginners. It carries our beginner-friendly, mold tolerant and compact, balcony-friendly badges.

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 OG 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 takes about 7 to 8 weeks from seed to harvest. The plant stays moderately compact, and its high resistance to common moulds and mildew makes it a good choice outdoors, although resistance is not immunity. It gives 300 to 500 g/m² indoors and 150 to 300 g per plant outdoors, depending on conditions.

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; in Quebec and Ontario that leaves time to finish well before autumn. Yields are best cases under good conditions, not promises. Check your local rules before you plant.

Taste, aroma and effect

Citrus and sweet, with earthy undertones and a pungent, skunky aroma. The high is uplifting and euphoric, with a soothing effect on the body. 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.
