I don't have any tipps for you. But I know who might have plenty.
The is a guy who runs a store called Kaly Seeds. I don't know his method but he somehow managed to cross Humulus scandens with cannabis.
Quote: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.

Maybe you'd like to brows his strains

Theres much info from him spread over the net. But it's mostly german and I'm too lazy to translate walls of text.
Everything is always okay in the end, if it's not, then it's not the end.
