Black Jack F1 Fast Version

Black Jack F1 Fast Version®: A Faster Photoperiod Version of the Classic Black Jack®

Black Jack F1 Fast Version® by Sweet Seeds is a feminized photoperiod line with ultra-fast flowering, developed as a faster version of Black Jack® (SWS01).

It is an F1 hybrid created by crossing a selected S.A.D. Sweet Afgani Delicious Auto® (SWS24) with the elite Jack Herer clone used in the original Black Jack®.

The genetic profile is fully balanced: 50% indica and 50% sativa. The manufacturer states 16-21% THC and around 1.1% CBD.

Origin: S.A.D. Auto® × Jack Herer

Black Jack F1 Fast Version® is based on two Sweet Seeds lines.

S.A.D. Sweet Afgani Delicious Auto® provides the autoflowering component of the hybrid, while the Jack Herer side uses the same elite clone that was involved in creating the original Black Jack®.

The result is a photoperiod F1 hybrid with a shortened flowering period, not an autoflowering version.

Genetic Balance and Morphology

The 50% indica and 50% sativa ratio makes Black Jack F1 Fast Version® a balanced hybrid without pronounced dominance from either side.

Sweet Seeds describes the plants as vigorous and productive, with long, strong side branches carrying aromatic flowers.

This structure follows the overall Black Jack® concept and is retained in the faster version.

Flowering: 7-8 Weeks

For indoor environments, Sweet Seeds states a flowering period of around 7-8 weeks.

This refers specifically to the flowering stage of the photoperiod form, not the complete life cycle of the plant.

According to the manufacturer, Black Jack F1 Fast Version® shortens flowering by approximately one week compared with the original Black Jack®.

Aroma: Earth, Wood and Lemon

In the technical specifications, Sweet Seeds lists earthy, woody and lemon notes.

The general description also mentions a very sweet, incense-like aroma with citrus notes of lemon.

The profile can therefore be described as a combination of sweetness, incense, earthiness, wood and lemon freshness.

No specific dominant terpenes are listed in the provided description, so assigning a particular terpene composition without additional data would be inaccurate.

Psychoactive Character

Sweet Seeds describes the effects of Black Jack F1 Fast Version® as stimulating and psychoactive.

With a stated THC level of 16-21%, the strain is THC-dominant, while CBD is listed at around 1.1%.

These terms describe the stated subjective profile and do not guarantee the same response in every person.

Stated Productivity

For indoor environments, the manufacturer states approximately 500-600 g/m².

For outdoor settings, around 500-700 g per plant is listed.

These figures should be treated as Sweet Seeds reference specifications rather than as guaranteed results for an individual plant.

What Makes Black Jack F1 Fast Version® Stand Out

Black Jack F1 Fast Version® carries the technical code SWS49 and combines three key traits: photoperiod development, a fully balanced 50/50 genotype and a shortened flowering period of around 7-8 weeks.

The manufacturer states 16-21% THC, around 1.1% CBD, productivity of 500-600 g/m² indoors and 500-700 g per plant outdoors.

Its main aromatic directions are sweetness, incense, earth, wood and lemon, while the subjective profile is described as stimulating and psychoactive.
