Jack 47 is a modern hybrid-sativa cultivar bred from AK47 lineage. This strain is designed for those seeking high-yielding results, typically completing its flowering phase in 67 days. It is considered a moderate challenge for cultivators and demonstrates versatility by performing well in both indoor and outdoor growing environments.

The sensory profile of Jack 47 is defined by a specific hierarchy of terpenes, led by terpinolene as the dominant compound, followed by myrcene and caryophyllene. This combination creates a distinct aromatic signature that reflects the interplay between these primary and secondary constituents. The terpene structure serves as the foundation for the strain's overall chemical experience, ensuring a consistent sensory nuance for the user.

As a THC-dominant cultivar with approximately 20.5 percent THC and negligible CBD content, Jack 47 provides users with effects described as creative, uplifted, and happy. Due to these characteristics, it is often selected for occasions requiring focus, social interaction, or the stimulation of creativity. Currently, there are no recorded notable offspring derived from this specific genetic line.
