Regional Climate Adapted Lines

Breeders in Canada and northern Europe have been developing early finishing THC lines that reliably complete by late September outdoors. These are crosses between potent modern hybrids and hardy northern genetics selected over several seasons. The northern outdoor section on https://potentthcseeds.com lists such strains with the latitude and finish dates reported by growers who ran them. For anyone north of the forty fifth parallel, this category is worth more attention than the general catalogue.
