A look at whether chilling seeds before germination actually helps, and where the idea came from.

Cold stratification gets recommended for stubborn cannabis seeds on the strength of what works for temperate tree seeds. Cannabis does not have the deep dormancy those species evolved, so a week in the fridge does little beyond what plain soaking achieves, and freezing wet seeds outright kills them. The evidence for and against chilling, including a few side by side tests growers have run, is weighed up on https://breederregularseeds.com. Scuffing and a warm, dark towel still beat every cold trick I have tried.
