  • Pack Size: 3 PACK, 5 PACK


Introducing the Black Jack F1 Fast VersionĀ® (SWS49), a feminized and photoperiod-dependent strain with an ultra-fast flowering time. This remarkable hybrid is derived from the original Black JackĀ® (SWS01) by crossing it with a selected genetic line of S.A.D. Sweet Afgani Delicious AutoĀ® (SWS24) and the Jack Herer elite clone used in the original Black JackĀ®. This cross results in a potent and productive strain that maintains all the best qualities of the original while significantly reducing the flowering period.

Sweet and Aromatic Delight

Black Jack F1 Fast VersionĀ® features a delightful and complex aroma that is both sweet and enticing. The fragrance combines hints of incense with refreshing lemony citrus tones, creating a sensory experience that is both soothing and invigorating. The earthy and woody undertones add depth to its aromatic profile, making it a pleasure to cultivate and enjoy.

Vigorous Growth and High Yields

This strain is known for its robust growth and high yields. The plants develop strong side branches that are long and fully loaded with aromatic flowers. Despite its rapid flowering time of just 7-8 weeks, Black Jack F1 Fast VersionĀ® does not compromise on productivity or potency. Indoor growers can expect yields of 500-600 g/mĀ², while outdoor plants can produce 500-700 g/plant. The balanced indica and sativa genetics ensure a well-rounded growth pattern and effect.

sweet seeds logoFounded in 2005, Sweet SeedsĀ® has been a pioneering force in the feminised seed bank industry right from the start. The founders, who were passionate collectors of various marijuana genetics long before establishing Sweet SeedsĀ®, have driven the companyā€™s constant innovation and quest for new products. Their dedication led to significant advancements, including the development of autoflowering seeds. In 2013, they launched a groundbreaking ultra-fast flowering seed, F1 Fast VersionĀ®, which was a world first with no equivalent product on the market. That same year, they introduced The Red Family, a customer favourite known for its striking purple marijuana. At Big Hippo, we are proud to offer a comprehensive selection of Sweet SeedsĀ® products.
