Sure, if you have questions regarding a seedbank's reliability, post em up. Many seedbanks and breeders have their own forums on ICMag (owned by the same entitity that owns Seedboutique, Seedbay, and Nirvana) where they may be contacted directly. I think IC makes forums for the breeders whose product they distribute only, however. You may not find all the ones you are looking for, but it will be a start.

IMVHO... The Netherlands are not the place to start your search for pure landrace genetics... great for commercial hybrids and even medical strains, but since landrace stuff often is unsuitable for indoor growing... you may have to search closer to the actual source. But good luck; it sounds like excellent research material. Just out of curiosity- grant-funded university research or lab physically run by a pharma company?
