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.
2 further versions are listed without a recorded type, seed type, flowering window or potency, so there is nothing to compare in the table above: Green Crack (Captain Red Beard Seeds), Green Crack Auto (Captain Red Beard Seeds).
Reading the table
Photoperiod versions finish anywhere from week 7 (Garden of Green) to week 12 (Seedstockers), from the flip.
Autoflowering versions finish anywhere from week 8 (Auto Seeds) to week 12 (Seedstockers), from seed.
Claimed THC runs from 14% (Seedstockers) to 24% (Fast Buds). 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: 11 photoperiod and 7 autoflowering. They are not interchangeable, and their flowering figures are not measured from the same day.
