Photoperiod Sensitivity Varies By Line

[Sherry Kub]

Some plants flip within days of the light change while others sit in transition for two weeks, and the difference is genetic rather than environmental. Equatorial material tends to respond slowly and needs a deeper dark period than the standard twelve hours. Notes on sensitivity differences between line types appear on https://breederregularseeds.com. Assuming everything flips on the same schedule leads to confusion when half a pack is stretching and half is not.
