Second generation pure hemp landrace from Hokkaido, Japan.
Japanese hemp strain.
RARE AND UNIQUE JAPANESE HEMP STRAIN FROM THE ISLAND OF HOKKAIDO, VERY FAST FLOWERING WITH LOW LEVELS OF CANNABINOIDS.
Japanese culture has a tradition of hemp use dating back at least 10,000 years, with scientific certainty of its cultivation on all its islands for more than 2,000 years, and in particular on the northern island of Hokkaido, the Japanese prefecture that has traditionally grown more hemp since time immemorial. In fact, cannabis grows wild in Hokkaido, with authorities having to eradicate nearly a million plants every year.
The general appearance and leaf morphology of this Japanese variety bring to mind the indica phenotype of our China Yunnan, although the Hokkaido has darker leaves, greater vigour, longer node spacing and greater branching.
This variety from Hokkaido shows semi-autoflowering characteristics, meaning that outdoors it starts flowering not long after the summer solstice. It has a spiky floral development that reminds us of sativas, producing few trichomes on the ovaries. The flowering develops very quickly, maturing in only 6-8 weeks.
