HortiLab Seeds. A selection of premium quality cannabis seeds. HortiLab's founders spent many formative years learning the art of genetics at The Spice Of Life seeds facility in Switzerland. It was while honing their breeding skills that they suddenly realised that as great as the established Dutch and Spanish varieties of marijuana were, there was a big wide world of cannabis out there to be explored. Ever since, HortiLab has been collecting, growing and breeding exotic seed lines and clones from around the world in order to search for the holy grails of cannabis.
