Durban Poison Auto brings a late-nineties Humboldt favorite into autoflower form. The original Durban cut made waves locally, but its long flowering time kept it out of most commercial gardens. In 2021 Humboldt Seed Company was gifted that cut and began converting it into a stable auto line.
The result is a 90% sativa autoflower with extremely frosty green colas, a minty fuel and Christmas tree aroma, and a powerful, energized high. It is not the quickest auto in the catalog, taking up to 100 days from sprout to harvest, but the breeder points to the payoff in yield, cannabinoids, and terpenes.
The dense, light green flowers are also rated high for both solventless and solvent hash production.
Durban Poison Auto Lineage and Breeding
Converting a photoperiod clone to a true-breeding auto takes several years and at least four generations of sorting through offspring to keep the original traits. Humboldt Seed Company started from a minty phenotype of its Mint Jelly Auto, a line the breeder says holds an autoflower potency record.
The genetics are listed as Mint Jelly Auto x Durban Poison Het x Durban Poison Auto, selected from phenotype hunt number Durban Het #11. That selection keeps the classic Durban sativa character while adding the minty note and the automatic flowering trait.
Aroma, Flavor, and Effect
The smell is minty fuel layered with fresh Christmas tree pine and a hint of sweetness. On the palate, mint leads, pine and gas follow, and the finish stays clean and crisp rather than heavy.
The effect is described as a powerful energized high. Expect a fast, bright onset with strong mental drive and plenty of physical energy, true to the Durban reputation. It fits active daytime use, creative projects, and outdoor plans more than quiet nights in.
Growing Durban Poison Auto Indoors and Outdoors
The breeder rates performance as high in greenhouses, light-deprivation setups, and outdoors. Indoor performance is still listed at the R&D stage, so tent growers should see it as a promising but less proven option. Under lights, run 18/6 or 20/4 the whole cycle and allow up to 100 days from sprout to harvest.
Growth produces separate, bud-type flower formation with heavy trichome coverage and excellent yield. Give it a large container and leave room for sativa stretch, and use light LST early to open the canopy. Outdoors, the longer auto cycle still fits well within a summer season. For hash makers, harvest at peak trichome maturity to make the most of its high wash and solvent ratings.
