Also known as: Jack Black Auto
Overview
Black Jack Auto is a third-generation autoflowering strain developed by Sweet Seeds as the autoflowering version of their renowned Black Jack strain. This strain features a genetic composition of approximately 67% sativa, 30% indica, and 3% ruderalis, with THC levels ranging from 17-19% according to Sweet Seeds specifications, though some sources report higher THC content up to 24%. The strain is created from crossing Sweet Afgani Delicious Auto with an elite Jack Herer clone, combining the autoflowering characteristics of ruderalis genetics with the potent effects of its photoperiod parents Black Domina and Jack Herer.
The plant displays a robust and compact morphology with medium internodes and long branches extending from a thick central stem, producing dense buds covered in a thick layer of resinous trichomes. Plants typically reach heights of 40-110 cm both indoors and outdoors, making them suitable for discreet cultivation. The aroma combines sweet and incense notes reminiscent of cathedral incense from Haze genetics, with a flavor profile blending sweetness with spicy touches and a prolonged pleasant aftertaste. The strain is noted for its outstanding resin production and huge concentration of trichomes, making it excellent for extract production.

Growing Information
Black Jack Auto has a fast flowering cycle of approximately 9 weeks (63 days) from germination to harvest, making it ideal for novice growers due to its autoflowering nature. Indoor yields range from 400-550g/m² while outdoor yields can reach 40-250g per plant. The strain is beginner-friendly and forgiving, with ruderalis genetics making it more resistant to cold, pests, and watering issues. Plants respond well to 18-20 hours of light per day throughout the entire grow cycle. The strain performs well both indoors and outdoors, with outdoor cultivation preferring consistent sunlight and temperatures of 70-80°F. Indoor growers don't need to alter photoperiods to trigger flowering, as the plant automatically transitions from vegetative to flowering stage.
