Greenhouse Seeds is seen as one of the most successful seed banks of all time, winning numerous awards, and producing multiple world renowned strains of cannabis seeds. Much of this fame is thanks to the Arjan, the owner and cofounder of Greenhouse Seeds, and co-explorer/hunter of Strain Hunters. It is through his continued work to discover, breed, and experiment with landrace strains that Green House Seeds was able to build such a reputation for itself. And he has now been at it for over 25 years.
Often dubbed the King of Cannabis, Arjan has taken a personal and vested interest in ensuring that the seeds on offer at Greenhouse Seeds cover a wide range of traits and features. This means there is something for everyone at Greenhouse Seeds, no matter if you are an indica or a sativa lover, grow indoors or outdoors, or simply want an auto strain - you will be able to find seeds suited to you.
Working through their associated company, Strain Hunters, Greenhouse Seeds has also dedicated itself to furthering the cannabis cause, campaigning for the end to prohibition and aiming to preserve rare landrace strains. In Arjan’s Words:
“When I was just 17 years old I met an old wise man. He looked me in the eyes and gave me a cannabis seed. He told me that the cannabis plant can be so powerful to overthrow governments, and to change the planet. Ever since, my goal in life has been to legalize cannabis for medicinal and recreational use, for everybody. Taxes and regulation will create a safer world for our children, a world with less crime, better public health and a solid economy. I am humbled and proud to be helping this green revolution, because those who have history will shape the future”.
