Critical Jack Herer
Critical Jack Herer
Also known as: Critical Jack, CJH
Overview
Critical Jack Herer is a sativa-dominant hybrid cannabis strain created by Delicious Seeds through the crossing of Critical Mass (Critical Plus) genetics with the legendary Jack Herer strain. This hybrid was specifically developed to combine the uplifting, cerebral effects and haze-like flavors of Jack Herer with the faster flowering time and increased yields characteristic of Critical genetics. The strain maintains approximately 80% sativa and 20% indica genetics, resulting in a plant that exhibits strong, vigorous growth with thin sativa-like leaves and abundant branching.
The strain was designed to address one of Jack Herer's main limitations - its traditionally long flowering period - by incorporating Critical genetics that significantly reduce the flowering time while preserving the distinctive aromatic profile and effects of the original Jack Herer. Critical Jack Herer has gained recognition in the cannabis community, winning awards including 1st place in the Outdoor Sativa category at the UCLA Cup and achieving placement in various Cannabis Cups. The buds are characterized by their lime-green coloration with abundant white trichomes, creating a frosty, crystalline appearance that reflects the strain's potent resin production.

Growing Information
Critical Jack Herer is considered an easy-to-grow strain suitable for both beginners and experienced cultivators. It can be grown both indoors and outdoors with a flowering time of 60-70 days (8-10 weeks). Indoor yields range from 450-550g/m², while outdoor harvests can reach 800-1000g per plant. The strain prefers Mediterranean climates when grown outdoors and harvests in mid-October. Plants exhibit strong, vigorous growth with abundant branching but require attention to feeding, as they prefer lower-strength nutrients and can be sensitive to over-fertilization. The plants are tolerant to training techniques like topping, LST, and SCROG methods. Indoor growers should watch vegetative time as plants continue growing during the flowering period. The strain produces dense, resinous buds with heavy trichome production visible from the second week of flowering.
