Serious Seeds is a small firm, concentrated on the production of high-quality, stable and consistent varieties of cannabis seeds. Top quality smoking cannabis for our customers is the highest priority.

Independent and reliable lab tests (over 20 years of experience in this field) have shown that the different Serious Seeds strains produce the strongest plants (highest in THC content) available on the market today, averaging between 18-22%THC. These tests were done on plants grown from the same seeds as the customer gets.

The breeder behind Serious Seeds, Simon, is responsible for the material sold by the seed bank. He studied biology at one of the universities in Amsterdam and was always a non-smoker. He only discovered the merits of smoking pure marijuana after his study while traveling through Africa in 1986. Today he remains one of the few Dutch who smoke this wonder plant in its pure form as one should. From that moment on he started collecting seeds. Back in Holland he immediately started growing those seeds out for personal pleasure crossing what he thought were the best plants seemed a natural follow up. Contacts with other growers gave him access to different plants from which he also selected the best ones. The genetic background of this material was not always clear.

Simon taught biology at a high school when Alan Dronkers asked him to come and work at Sensi Seeds. It was quite a career change to do that but he never felt sorry about it. After some time working for Sensi he left and started a seed company with some American pot refugees. That year (1994) the AK-47 as well as the Chronic won prices at the American Cannabis Cup festival in Amsterdam. That first seed company with the Americans soon fell apart however, and in 1995 Serious Seeds was grounded. It has always been a Serious policy to have the products grown from the different seeds available to try out in some of the best coffee shops in Amsterdam. The 'Greenhouse' is one of those coffee shops which carry Serious' products to smoke from the start in 1995 to this date. Greenhouse coffee shop won a Cannabis Cup in 1995 with the Kali Mist grown by Serious Seeds. In 1996 another famous Amsterdam coffee shop, the Dampkring, won the Overall Cup at that year's Cannabis Cup with White Russian, the newest Serious strain. Another serious shop from the early days is the Blue Bird and recently also the Dread Rock, they really sell what is listed, instead of anything under an often asked for name.

Serious has always been a small company, and prefers to stay like that. We love to smoke ourselves, and basically we try to develop new and interesting plants to grow and smoke for our own pleasure, as well as for our clients.

This means we don't work to produce something new every year for commercial reasons or to compete in the next contest. We want to put a new name out when we think we have something worth while for pot growers and smokers to try out.
