Lineage: Jack Herer's piney, cerebral backbone crossed with Gorilla Glue's heavy resin production — then rebuilt as an autoflower by Blimburn Seeds. The result finishes in 9–10 weeks from seed without any light-schedule management, which matters when you're running a perpetual cycle or working with limited space. THC tests typically land in the 20–25% range, and the terpene profile skews citrus-forward with a diesel and skunky edge underneath — sharper than the softer Jack phenotypes most people know.

Yields come in around 400–500g/m² with moderate effort, meaning you'll want to dial in your VPD and feed schedule, but you won't need to be an expert to hit those numbers. The plant stays workable in both indoor and outdoor setups. A solid pick for growers who want a Jack-influenced head effect without committing to a full photoperiod run.

Growing Jack Herer x GG

Jack Herer x GG is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 9-10 weeks with yields of 400-500g/m2. Plants typically reach 60-100cm indoors.

The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.
