Black Jack F1 Fast Version
Also known as: Black Jack F1 Fast, Black Jack Fast Version
Overview
Black Jack F1 Fast Version is a feminized, photoperiod-dependent cannabis strain developed by Sweet Seeds as an ultra-fast flowering version of their celebrated Black Jack strain. This F1 hybrid is the result of crossing a selected genetic line of Sweet Afghani Delicious Auto (S.A.D. Auto) with an elite Jack Herer clone that was also used in the original Black Jack. The strain maintains the potency and productivity of its parent while reducing flowering time by approximately one week.
This perfectly balanced 50% Indica/50% Sativa hybrid produces vigorous, high-yielding plants with characteristically strong, long side branches that become densely packed with aromatic flowers during flowering. The buds are known for their resinous quality and substantial calyx development. Black Jack F1 Fast Version is particularly valued by cultivators for its tolerance to both over and underfeeding, exceptional resistance to mold and fungal attacks, and forgiving growing characteristics that make it suitable for both beginners and experienced growers. The strain's robust genetics and shortened flowering period have made it a popular choice for both indoor and outdoor cultivation.

Growing Information
Black Jack F1 Fast Version is an easy-to-grow strain suitable for cultivators of all experience levels. It has an ultra-fast flowering time of 7-8 weeks indoors, which is one week shorter than the original Black Jack. Indoor yields range from 500-600g/m², while outdoor cultivation can produce 500-700g per plant. The strain is particularly resistant to mold and fungal attacks and is tolerant of both overfeeding and underfeeding. It performs well in indoor, outdoor, and greenhouse environments. The plants develop strong, long side branches that benefit from super-cropping techniques for advanced growers. Outdoor harvest typically occurs in mid-September in the Northern Hemisphere. The strain grows with hybrid vigor and may require support due to heavy bud development on the side branches.
