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 Critical (IZI Seeds), Auto Critical+ (Linda Seeds), Critical+ (Linda Seeds), Critical (Pev Seeds).
Reading the table
Photoperiod versions finish anywhere from week 6 (Dinafem) to week 12 (Big Head Seeds), from the flip.
Autoflowering versions finish anywhere from week 8 (Blimburn Seeds) to week 12 (CBD Seeds), from seed.
Claimed THC runs from 10% (Blimburn Seeds) to 22% (BulkSeedBank). 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: 13 photoperiod and 10 autoflowering. They are not interchangeable, and their flowering figures are not measured from the same day.
