Critical Jack
Read the ride before you spark it
Critical Jack earns its DeePuff fit from 29.3% THC, a chill evening profile led by Caryophyllene, and effects that lean calmer and more body-forward.
Critical Jack, also known as "Critical Jack Herer," is a hybrid marijuana strain cross between Critical Plus and Jack Herer. Critical Jack delivers functional cerebral effects with a flavorful blend of lemon, pine, and floral aromas. Its effects are light on the body and stimulating to the mind, allowing one to fixate their attention strongly on whatever task is at hand. Uplifting qualities make Critical Jack a popular daytime remedy for depression, appetite loss, and headaches. Critical Jack’s harvest falls between late September and early October outdoors, while indoor gardens will finish around day 60 of flowering.

The aromatic compounds that define this strain's unique characteristics and effects
What are Terpenes?
Terpenes are aromatic compounds found in cannabis that contribute to each strain's unique smell, taste, and effects. They work synergistically with cannabinoids in what's known as the "entourage effect" to enhance or modify the overall experience.
