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.
Reading the table
Photoperiod versions all finish around week 7, from the flip.
Autoflowering versions finish anywhere from week 7 (Royal Queen Seeds) to week 9 (PowerStrains), from seed.
Claimed THC runs from 20% (PowerStrains) to 22% (Royal Queen 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: 1 photoperiod and 2 autoflowering. They are not interchangeable, and their flowering figures are not measured from the same day.
