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.
6 further versions are listed without a recorded type, seed type, flowering window or potency, so there is nothing to compare in the table above: Northern Light Autoflowering (Dutchfem), Northern Light Autoflower (Hy-seeds), Auto Northern Light (IZI Seeds), Auto Northern Light (Linda Seeds), Northern Light (Linda Seeds), Northern Light (Seeds Genetics Co.).
Reading the table
Photoperiod versions finish anywhere from week 6 (BulkSeedBank) to week 12 (Nirvana), from the flip.
Autoflowering versions finish anywhere from week 6 (Victory Seeds) to week 12 (Blimburn Seeds), from seed.
Claimed THC runs from 14% (Nirvana) to 19% (Expert 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: 8 photoperiod and 12 autoflowering. They are not interchangeable, and their flowering figures are not measured from the same day.
