R-Kiem Cannabis Seeds

Spain (founded)

Established in Barcelona in 1998, R-Kiem Seeds is an artisanal breeder cooperative formed by a passionate collective of Catalan growers, breeders, and international geneticists. Built on a foundation of genetic preservation and organic cultivation, the seed bank has spent over two decades identifying, collecting, and stabilizing rare landraces alongside elite global clone-only cuts.

R-Kiem Seeds is particularly celebrated within the international extraction and hash-making communities. Their breeding philosophy focuses on maximizing glandular trichome density, structural resilience, and distinct organoleptic profiles. Every batch of seeds undergoes 100% organic production and rigorous hand-selection under controlled temperature and humidity conditions to ensure maximum germination viability and genetic stability.

Their globally decorated catalog includes multiple cannabis cup winners and fan favorites such as El Xupet Negre, Sublimator, Portela, Negra 44, Icer, 2y2, and Z-Kiem. Offering high-potency photoperiod feminized strains, regular genetics, and automatic varieties, R-Kiem Seeds remains a premier choice for commercial extractors and craft connoisseurs seeking unmatched resin density and bold flavor.
