Greenhouse Seeds Seed Bank

The Greenhouse Seeds seed bank is one of the most reputed institutions in the cannabis seeds market. Not only for its wide catalogue of auto-flowering and feminized seeds, but also for its creator, the proclaimed "King of Cannabis" Arjan Roskam, who has turned his institution into an entire seed empire in Amsterdam. In this way, his company has been in constant development and currently has a line of grow shops and even an apartment rental service in the heart of Amsterdam.

History and work culture of Greenhouse Seeds

Greenhouse was founded in 1985 in Amsterdam, at the height of the legal cannabis cultivation boom. Its creator, Arjan Roskam, had made some trips to Southeast Asia, where he would come into contact with the wide world of marijuana seeds. In Thailand, he met a man who claimed to be able to cure withdrawal symptoms from marijuana-based hard drugs, and was this fact that sparked Arjan Roskam's first professional interest in the world of seed cultivation.

Upon his return from his travels in regions such as Nepal, Arjan decided to apply some of the knowledge he had acquired about the way in which cannabis seeds work and to start doing his field work on strains such as Haze. At the time, seed strains from Ecuador were exotic and not yet fully stabilized in Europe, so many Sativa seed lovers had to cross the ocean to try Mexican, Thai and other such heirloom Sativas.

This was where the "King of Cannabis" gained notoriety. Roskam returned to travel through Southeast Asia with a single objective: to obtain Sativa seeds to satisfy the demands of the Dutch dispensaries. However, these were not met with the expected response and the first generation of Greenhouse Haze did not particularly take off. However, it is common knowledge that the road to innovation and entrepreneurship is not an easy one, nor does success happen overnight.

Seeing that Dutch dispensaries despised his Haze varieties, Roskam decided to open his first coffee shop in 1992. Here, Greenhouse Seeds could make its improved Sativa strains prepared in Roskam’s cellar available to consumers. Success was not far away, and the first prizes began to appear at cannabis fairs such as the High Times Cannabis Cup.

One of the maxims of this seed bank is to obtain new varieties of seeds from all over the world. In this way, the trips that Arjan Roskam and his inseparable partner, the late Franco Loja, became well-known both within the global cannabis community for their Strain Hunters program. In this space, both traveled around the world in search of the most exotic and exclusive seeds to obtain their own wonderful varieties at their headquarters in Amsterdam.

Today, Greenhouse Seeds is one of the most successful seed banks in the world. It has a catalog of more than 20 feminized and automatic varieties, the product of the many trips carried out by its founder. Currently, Greenhouse also has a line of nutrients, a wide network of coffee shops, and one of the most sought-after merchandising lines in the world of cannabis seeds.

Best Greenhouse strains

Next, we will present you with the most outstanding characteristics of some of Greenhouse’s most popular cannabis seed varieties.

As such, all of their products have all the guarantees of quality and are preserved in such a way that they arrive in the hands of the consumer with all of their properties fully intact.

First up is their White Widow variety, a classic for the enthusiasts of resistant and productive seeds. It is a strong Indica variety, which does not require much care, making it particularly coveted by collectors around the world. It is the product of a cross between South Indian and Brazilian varieties, which are responsible for the seeds’ characteristic resistance and adaptability.

The Super Silver Haze variety is one of the most coveted Greenhouse strains worldwide. It is one of the most Indica Sativa seeds of all and is the result of a cross between the Skunk and Northern Lights strains. This variety has managed to win the High Times Cannabis Cup on three consecutive occasions, in 1997, 1998 and 1999, making it one of the champion varieties, having received further prizes throughout history.

The feminized marijuana seeds Franco's Lemon Cheese are a tribute to Franco Loja, the insatiable breeder who collaborated hand in hand with Arjan Roskam. This variety was a favorite for the breeder, who unfortunately died of malaria in 2017 upon his return from a trip to Africa where he was performing CBD extractions. Franco's tribute strain is tasty, productive, and beautiful – Everything Loja would look for in a seed.

For all these reasons, the Greenhouse seed bank leads one of the most competitive markets that exist, that of Cannabis seeds. This is due to the great work that this bank performs traveling around the world and collecting seeds, in addition to the good genetic work carried out in obtaining their new varieties.
