Jack Hammer
Jack Hammer is a modern hybrid strain developed from Sannie's Jack. As a result of its specific lineage, it requires moderate cultivation skill to manage successfully in both indoor and outdoor environments. Growers can expect a high yield from this variety, which reaches maturity after a 77-day flowering period.
The sensory profile of Jack Hammer is defined by a primary presence of myrcene, followed by secondary caryophyllene and tertiary limonene content. These terpenes work in concert to establish the cultivar's distinct aromatic and flavor characteristics. This chemical composition remains the foundation of its experiential profile and distinguishes it from other hybrid offerings.
Jack Hammer is a THC-dominant strain recognized for delivering effects described as relaxed, happy, and uplifted. These properties make the strain a functional choice for individuals seeking support for stress, pain, or assistance with sleep. The genetic legacy of this cultivar is maintained through notable offspring, which include Blue Hammer and Sativa Queen.

Russo 2011: only terpene that is a selective full CB2 agonist (100 nM); Gertsch et al. 2008: acts as dietary cannabinoid; unique anti-inflammatory and gastric cytoprotective properties.
Russo 2011: increases serotonin in prefrontal cortex + dopamine in hippocampus via 5-HT1A; Johns Hopkins 2024: significantly reduced anxiety vs THC alone.
Effects
Reported effects — derived from terpene chemistry and cannabinoid profile.
