Double Jack Auto

Double Jack Auto is a hybrid cannabis strain with up to 22.0% THC, known for its euphoric effects and citrus and earthy flavor profile.

Double Jack Auto is an autoflowering cannabis strain developed by crossing the popular Jack Herer with an undisclosed autoflowering ruderalis variety. This strain inherits the cerebral, uplifting qualities of its sativa-dominant parent while incorporating the automatic flowering trait that makes it suitable for growers seeking a faster, less light-dependent cultivation cycle. The strain emerged in the early 2010s as part of the growing trend toward autoflowering varieties that could complete their life cycle regardless of light schedules, making them particularly appealing to novice growers and those with limited space or challenging outdoor climates.

Visually, Double Jack Auto plants typically exhibit a compact, bushy structure with medium internodal spacing. The buds are dense and resinous, often displaying a frosty coating of trichomes that gives them a sparkling appearance. Coloration ranges from deep forest green to lighter lime hues, with occasional purple or orange pistil highlights depending on environmental conditions during cultivation. The strain's autoflowering genetics result in a relatively uniform plant size and predictable flowering timeline, which contributes to its popularity among cultivators seeking consistency.

Notable features include its relatively short life cycle (typically 8-10 weeks from seed to harvest) and its ability to thrive in both indoor and outdoor environments. While not as potent as some photoperiod Jack Herer phenotypes, Double Jack Auto maintains a respectable THC content and delivers a balanced experience that combines cerebral stimulation with mild physical relaxation. The strain's automatic flowering mechanism means it will begin flowering based on age rather than light cycle changes, making it less sensitive to light pollution or irregular lighting schedules.
