Dutch Passion now have two varieties (as well as a THC-V variety I wasn’t aware of)
CBG-force and auto CBG-force for 15-35 euro/seed claiming ~15%CBG and 1:100 THC:CBG ratios
Hemp Direct is selling something called Desert Snow claiming up to 20% and less than 0.3 (I suspect this is from Oregon CBDs work).
Hoku hemp has a variety of CBG strains, apparently built off European varieties (Italian and swiss).
I have grown the Kwick seed CBG. It was much more resinous than the CannapAroma, but fairly airy, with tall fiber structure. Much more promising, though still only advertised as an 8% CBG plant.
Lastly, this is something that has sort of thrown me through a loop on the CBG breeding theory and I would love if someone could explain it to me: the Whistler Farm’s Shiatzu Kush clone that is about 1:1 or 2:1, THC:CBG. I would have thought this ratio shouldn’t really exist. So clearly other things that I don’t understand yet are happening here.
