Kalyseeds specializes in unusual hybrids between cannabis and Japanese hops. After years of experiments the first crossings of the new, so-called PAC-strains, are now available.

Jap.hop X Mex.Sativa

The Jap.hop is a hybrid from 1998, between Purple Star and japanese Hop. He has long grown faint-vigorous and stunted, in 2008 it was back to normal in growth. This hybrid is the ancestor of all PAC strains.

This Pseudoacercannabis (PAC) line, a hybrid between Humulus Japonicus and Cannabis, is not available as seed - but was used for different crossings.
