Critical Jack Auto

Critical Jack Auto is an indica-dominant autoflowering hybrid strain that combines approximately 60% indica and 40% sativa genetics. The strain originates from a cross between Critical Plus 2.0, Jack Herer, and an autoflowering ruderalis strain, developed by breeders including Dinafem Seeds. This autoflowering variant maintains the exceptional qualities of the original Critical Jack while offering the convenience of automatic flowering without requiring photoperiod changes. The strain is celebrated for its genetic stability, producing vigorous plants that thrive in diverse environments and offer a fast-growing cycle of 8-10 weeks from seed to harvest.

Critical Jack Auto produces compact, medium-height plants typically reaching 3-5 feet tall with dense, resin-covered buds that exhibit a crystalline sheen from abundant trichomes. The flowers are characterized by bright green coloration with yellow pistils and exceptional resin production. The strain has earned recognition in cannabis competitions, including awards for outdoor sativa categories and extraction quality. Despite its autoflowering nature, Critical Jack Auto maintains impressive yields and potency, making it an excellent choice for both novice and experienced growers seeking a reliable, high-quality harvest with minimal effort.
