Sir Jack Auto (Exotic Seed) Feminized

Sir Jack Auto: Jack Herer DNA, Auto Convenience

Sir Jack Auto comes from Exotic Seed and carries a lineage growers will recognise immediately. The cross pairs Sir Jack, a direct descendant of the iconic Jack Herer, with Auto Skunk, which brings ruderalis genetics into the mix. The result is a 50/50 sativa/indica hybrid that behaves like a true all-rounder rather than leaning hard in either direction. Sir Jack contributes the resin output and cerebral character the Jack Herer name is known for, while Auto Skunk adds compactness and light-cycle independence without diluting what makes the parent strain worth growing. These are feminized seeds that flower automatically, so every plant in the tent is productive from the start.

12 Weeks, No Schedule, Solid Returns

Seed to harvest takes 12 weeks, with a 6-week flowering window inside that cycle. No light schedule management is needed at any point, which keeps the grow straightforward from start to finish. Height stays consistent across environments at 100-120cm, compact enough to fit a standard tent without aggressive training and manageable outdoors without taking over the space. Indoor yields run 500-550g/m², which is strong output for an autoflower and makes this a productive choice for growers who want results without a photoperiod commitment. LST works well here and can help push that yield further; topping is worth approaching with caution on autos, as the recovery window is tighter than with photoperiod plants.

Warm Smoke, Wide-Awake Effects

The aroma is one of Sir Jack Auto's most distinctive qualities: a warm incense-like character underpins bright citrus and herbal notes, giving the smoke a depth that goes beyond a straightforward lemon profile. Effects are cerebral and energetic, with an uplifting, sociable quality that makes this a daytime-to-evening strain rather than a nightcap. There is a relaxing tail, but it does not tip into sedation. If you need to stay sharp and focused, this is not the session for it; Sir Jack Auto is better suited to social situations, creative headspace, or simply unwinding without switching off entirely. Potency is meaningful without being overwhelming, consistent with what you would expect from a resinous Jack Herer descendant.
