Black Jack F1 Fast Version from Sweet Seeds is a Feminised F1 Fast Version of the original Black Jack, bred from an elite Jack Herer clone crossed with S.A.D. (Sweet Afgani Delicious) Auto genetics. It preserves the Black Jack lineage while shortening indoor flowering, producing densely resinous flowers with a sweet, floral and incensed flavour rounded by clear lemon-citrus highlights that give the cultivar a recognisable sensory edge.
Performance & commonly reported effects
Growers and users report a reliably balanced, 50/50 hybrid character: the experience is commonly described as relaxed and gently uplifting with clear euphoric notes rather than heavy sedation. The flavour profile emphasises sweet and citrus elements with floral and earthy undertones, making it a versatile choice for those who value both taste and a balanced, pleasant uplift.
Grower advice & ideal setup
Breeder documentation and grow reports show consistent, vigorous plants that perform well in both indoor and outdoor setups and respond positively to standard training; strong side-branch development supports productive bud sites. The Fast Version reduces the indoor flowering period by roughly one week versus the original Black Jack, favouring growers who need an earlier harvest window outdoors. This variety suits controlled indoor environments and Mediterranean-style outdoor seasons where a mid- to early-September harvest is possible.
Choose Black Jack F1 Fast Version if you want a Feminised, fast-flowering take on a classic Jack Herer lineage that keeps the original’s aromatic sweetness and balanced, euphoric performance.
