Emperor Jack Autoflower Cannabis Seeds Feminized

Genetics & strain profile

Emperor Jack Autoflower is a feminized autoflowering strain bred by Quebec Cannabis Seeds. It comes from Jack Herer and Northern Lights. It is mostly sativa with 20% THC, and the page describes it as easy to grow. It carries our beginner-friendly 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 Emperor 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 8 to 10 weeks. The plant stays compact and manageable, which suits indoor spaces of any size. It gives 250 to 450 g/m² indoors and 150 to 250 g per plant outdoors, depending on the environment. The range is wide, so your own result depends on light, space and care, and the low end is the safer number to plan around.

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 spicy, with citrus notes. The effect opens with a euphoric, uplifting rush that lifts mood and creativity. At 20% 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.
