There's no Dinafem thread for a variety of reasons. RIU is a US based forum that tends to support US based breeders. In fact theres a largely unfounded disdain for European breeders here. People routinely shit on the Dutch breeders here ... I've been to Amsterdam and I can tell you the Dutch can breed some damn fine cannabis. I've also grown some Dinafem strains, most recently Critical+ 2.0 and its been a good experience all around.
Its also just not trendy to be into old school European breeders in general right now. Maybe they should start naming their strains after desserts.
That being said, I actually agree with your original breeder recommendations. If OP is in the US s/he should be looking at places like JBC Seeds, DC Seed Exchange, Great Lakes Genetics, Oregon Elite, Area 51 Seedbank or even buying direct from breeders like Eso's. Its not that Dinafem isn't good IMO, its just why deal with international shipping and buying from an overseas breeder when straight fire is being bred right here at home.
