Well, hearsay and gossip more than info maybe, but the story (
mrnice.nl/dhtml/history) seems to be that Shanti`s genetics and maybe more importantly Neville`s went to Switzerland and Arjan doesn`t have all the plants to breed all the strains he`s selling, so if you get a non- feminised Greenhouse seed it`s debatable how legit it is.
Having said that you`d have to grow both varieties of say Neville`s Haze or something to really check.
Like Cerebro once pointed out to me hippies + drugs + money = disinformation + arguments or that seems to be the pattern anyway.
