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: Runtz auto (Captain Red Beard Seeds), Runtz (Hy-seeds), Runtz (Linda Seeds), Runtz Auto (Linda Seeds), Auto Runtz (Mr. Hide Seeds).
Reading the table
Photoperiod versions finish anywhere from week 7 (Barney's Farm) to week 12 (Dr. Krippling), from the flip.
Autoflowering versions finish anywhere from week 8 (Auto Seeds) to week 12 (Original Sensible Seeds), from seed.
Claimed THC runs from 16% (Super Strains) to 29% (Barney's Farm). 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: 10 photoperiod and 10 autoflowering. They are not interchangeable, and their flowering figures are not measured from the same day.
