Killer Jack
Also known as: Killer Jack Herer, Killer Jack Haze
Killer Jack Strain Overview
Killer Jack is a sativa-dominant hybrid cannabis strain that represents a modern interpretation of the classic Jack Herer genetics. The strain was developed by crossing Jack Herer with an undisclosed indica strain, creating a balanced hybrid that maintains the cerebral qualities of its famous parent while adding more physical relaxation. Breeders aimed to create a strain with the uplifting, creative effects of Jack Herer but with slightly more body presence and shorter flowering time.
The strain typically produces medium to large-sized buds with a dense structure and vibrant green coloration, often accented by orange pistils and a generous coating of trichomes. The visual appeal is enhanced by the resin production, which gives the buds a frosty appearance. Killer Jack has gained popularity among both recreational and medical users for its balanced effects and reliable performance.
Notable features include its relatively fast flowering time compared to pure sativa strains and its adaptability to various growing conditions. The strain has become particularly popular in European markets and has developed a following among users who appreciate the Jack Herer lineage but desire slightly more physical effects. While not as historically significant as its parent strain, Killer Jack represents an evolution of classic genetics for contemporary cannabis consumers.

Killer Jack Strain Growing Information
Killer Jack is considered a moderate difficulty strain to cultivate, suitable for growers with some experience. The flowering time typically ranges from 8-10 weeks indoors, with outdoor harvests occurring in late September to early October in northern hemisphere climates. Plants can reach heights of 150-200 cm indoors and up to 250 cm outdoors if given sufficient space.
Indoor yields average 400-500 grams per square meter under optimal conditions, while outdoor plants can produce 500-700 grams per plant. The strain responds well to both soil and hydroponic growing methods and can be trained using techniques like SCROG (Screen of Green) or LST (Low Stress Training) to maximize yields. Killer Jack prefers a Mediterranean-like climate when grown outdoors, with plenty of sunlight and moderate humidity.
Special considerations include maintaining good air circulation to prevent mold, as the dense buds can be susceptible in humid conditions. The plants benefit from regular feeding during the vegetative stage but require careful nutrient management during flowering to avoid nutrient burn. Growers should monitor pH levels closely, as the strain can be sensitive to pH fluctuations.
