Advanced Seeds was initially created after a group of Spanish breeders spent time researching Dutch genetics. Despite the incredible aromas and tastes of these genetics, the breeders found a number of problems with germination and vigor. In light of this, these breeders decided to set up their own seedbank in 1999.

During their first years, Advanced Seeds started selling their strains from their small grow shop in Murcia, Spain. It was a very basic set-up, with no packaging for products and no marketing to speak of; sales were slow, despite the high quality of their strains.

To achieve a substantial growth, Advanced Seeds decided to create a line of feminized genetics that combined a simple cultivation process for consumers, with the incredible flavors that they had seen in legendary Dutch genetics. Such was the success of these strains that Advanced Seeds became a professional seedbank in 2006.
