About Jack Haze

JHzSativa Hybrid

Jack Haze emits a distinctly dank scent, reminiscent of damp soil or a musty basement. Lurking underneath is a surprisingly piney, woodsy aroma. Grinding up these nuggets gives off some notes of spice and pepper.

Dutch Flag Dutch Bred

Jack Haze is a cerebral, stimulating strain built on the backs of some staples of cannabis breeding. The sativa-leaning hybrid is a cross between ubiquitous Jack Herer and highly resinous Super Silver Haze. This strain’s potency is sure to impress even experienced cannabis consumers. Its THC content has been measured at between 12% and 22%.

Jack Haze tends to have medium-sized blossoms that hold an elongated formation and taper down slightly at their ends. In keeping with their sativa lineage, these buds tend to be more loose and fluffy than dense and compact. The ragged-looking leaves are a pale sage green and are twisted through with curly brown and orange hairs -- which are actually pistils, botanical structures meant to help with fertilization. Finally, parent strain Super Silver Haze passes on its propensity for high resin production, as Jack Haze’s flowers are covered in translucent and sticky white trichomes.

When it’s properly cured, Jack Haze emits a distinctly dank scent, reminiscent of damp soil or a musty basement. Lurking underneath is a surprisingly piney, woodsy aroma. Grinding up these nuggets gives off some notes of spice and pepper. When it is burnt, Jack Haze gives off an acrid, sour-tasting smoke that may tickle the palate and trigger coughing or watery eyes. This harsh smoke carries a pleasant flavor of pine with some lemon on the exhales, though.
