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.
3 further versions are listed without a recorded type, seed type, flowering window or potency, so there is nothing to compare in the table above: Granddaddy Purple (New420Guy Seeds), Granddaddy Purple (Seeds Genetics Co.), Granddaddy Purple Auto (STRNG Seeds).
Reading the table
Photoperiod versions finish anywhere from week 8 (Purple Caper Seeds) to week 12 (Purple Caper Seeds), from the flip.
Autoflowering versions finish anywhere from week 8 (Auto Seeds) to week 12 (Auto Seeds), from seed.
Claimed THC runs from 19% (Royal Queen Seeds) to 20% (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: 8 photoperiod and 3 autoflowering. They are not interchangeable, and their flowering figures are not measured from the same day.
