Our take
Jack Cookies Autoflower combines two well-known parent strains — Jack Herer and GSC — into a sativa-dominant plant that finishes its entire cycle in as little as 56 days. With THC testing at 30%, it sits at the higher end of what autoflowers typically deliver. The flavor profile layers diesel and citrus over sweet, earthy undertones. Best suited to growers with at least one or two grows under their belt.

Growing notes
Rated intermediate, Jack Cookies Autoflower rewards growers who already understand basic feeding and light schedules. It stays short, so tight spaces work well indoors. The 56–70 day auto cycle applies both indoors and out. Outdoors, plan for a late September to mid-October harvest. Consistent watering and a light-training approach like low-stress training can help push yields closer to the 600 g/m² ceiling.
