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: Trainwreck (Hy-seeds), Trainwreck (New420Guy Seeds).

Where they differ

Reading the table

Photoperiod versions finish anywhere from week 8 (Barney's Farm) to week 10 (Homegrown Cannabis Co), from the flip.

Autoflowering versions finish anywhere from week 12 (Royal Queen Seeds) to week 13 (Royal Queen Seeds), from seed.

Claimed THC runs from 13% (Humboldt Seed Organization) to 28% (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: 8 photoperiod and 1 autoflowering. They are not interchangeable, and their flowering figures are not measured from the same day.
