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.
5 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 White Widow (Linda Seeds), Auto White Widow (Mr. Hide Seeds), White Widow Auto (New420Guy Seeds), White Widow Autoflower (Seeds Genetics Co.), White Widow Auto (STRNG Seeds).
Reading the table
Photoperiod versions finish anywhere from week 6 (Trikoma Seeds) to week 12 (Delta 9 Labs Seeds), from the flip.
Autoflowering versions finish anywhere from week 5 (Ministry of Cannabis) to week 12 (00seeds), from seed.
Claimed THC runs from 9% (Dinafem) to 26% (Victory 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: 40 photoperiod and 24 autoflowering. They are not interchangeable, and their flowering figures are not measured from the same day.
