Lineage: Jack Herer and White Widow Auto, both workhorses in their own right, crossed by Blimburn Seeds into a single autoflowering sativa that finishes in 10–12 weeks without a light-schedule change. The numbers here are aggressive — lab panels on this cross have clocked 40–50% THC, which puts it firmly in the upper tier of what autoflowers currently produce. Phenotypes tend toward fruity and citrus on the nose with a skunky finish that leans more classic dispensary than candy shop. Under a dialed-in setup, growers are pulling 400–500g/m², solid for an auto. Difficulty sits at moderate, so you'll want to have a few runs under your belt — it responds well to light LST but punishes heavy stress training at this speed. Works in both indoor and outdoor environments.

Best suited to intermediate growers who want a fast-cycling, high-potency sativa without managing photoperiod timing.
