About this format
Cannabis seeds are sold as collectable souvenirs and for the preservation of genetics. Feminized seeds grow into female plants, autoflowers switch to bloom on their own regardless of light schedule, and regular seeds produce both sexes for breeding. Germination is illegal in many countries — know your local law before you buy.
From the supplier
Sir Jack Auto: Jack Herer DNA in a Schedule-Free Package
Sir Jack Auto comes from Exotic Seed and carries a lineage that earns its name. The cross is Sir Jack, itself a descendant of Jack Herer, bred with Auto Skunk to bring in ruderalis genetics. What that means in practice: the resin output and cerebral character the Jack Herer line is known for, in a plant that flowers on its own clock. The 50/50 sativa/indica split makes this an all-rounder rather than a leaner, neither a committed sativa stretch nor a heavy indica sink. These feminized seeds are built for growers who want the Jack Herer experience without the photoperiod commitment.
For the same auto without the punch, Sir Jack Auto Pure CBD is the CBD-forward version at 9 to 10 weeks from seed.
Compact Grower, Serious Yields
Seed to harvest runs 12 weeks, with 6 of those weeks in flower. No light cycle management is needed, which keeps the grow straightforward from start to finish. Height stays at 100-120cm across both indoor and outdoor environments, consistent enough that tent growers can plan their space without surprises. Indoors, yields run 500-550g/m², which is strong output for a plant this size. LST works well here and can help open the canopy further. Topping is worth approaching with caution on autos, as the recovery window is shorter than on photoperiod plants.
Warm Incense, Sharp Citrus, Clear Head
The aroma is where Sir Jack Auto stands apart from most compact autos. There is a warm, incense-like herbal base that builds into a sharper citrus edge on the exhale. It is not a simple lemon profile; the herbal depth gives it more character than that. Effects run cerebral and energetic, sociable rather than sedating, which makes this a daytime-to-early-evening strain rather than a nightcap. A relaxing tail rounds things out without pulling toward couch-lock. For growers used to auto genetics that trade character for convenience, Sir Jack Auto is the counter-argument. Rather steer flowering yourself? Exotic Thai is the photoperiod sativa on the same shelf, uplifting and made for daytime use.
