20 breeders sell a variety under this name. Their flowering windows, seed types and claimed potency in one table, so you can see where they agree and where they do not. Reference data for planning a grow, not a measurement of your plant.
Catalogue data last updated 17 October 2026.
Potency figures are each breeder’s own claim for their own seed. Nothing on this page is a lab result, and two breeders quoting the same number did not test the same plant.
4 further versions are listed without a recorded type, seed type, flowering window or potency, so there is nothing to compare in the table above: Auto Jack Herer (BulkSeedBank), Jack Herer Autoflowering (Dutchfem), Auto Jack Herer (IZI Seeds), Jack Herer Auto (STRNG Seeds).
Reading the table
Photoperiod versions finish anywhere from week 7 (Blackskull Seeds) to week 12 (Seed City Seeds), from the flip.
Autoflowering versions finish anywhere from week 8 (Sensi Seeds) to week 12 (Advanced Seeds), from seed.
Claimed THC runs from 11.27% (House of the Great Gardener) to 24% (Seed City Seeds). Those are the breeders’ own figures for their own seed, not lab results on a shared sample.
Both light cycles are sold under this name: 16 photoperiod and 9 autoflowering. They are not interchangeable, and their flowering figures are not measured from the same day.
