01Beginnings
Serious Seeds is an Amsterdam seed company, and the material it sells is credited to a breeder who appears in the sources only as Simon1. He studied biology at a university in Amsterdam and later taught the subject at a high school1. His seed collecting began in 1986, during a trip through Africa1. The profile notes that the genetic background of the material he gathered was not always clear1.
There was a detour before the company existed. Simon was teaching when Alan Dronkers invited him to work at Sensi Seeds1. After some time there he left and started a seed company with a group of Americans, whom the profile calls pot refugees1. That first venture soon fell apart, and Serious Seeds was founded in 19951. Simon's surname, and any detail about the company's early premises or funding, are not documented in the sources used here.
02The Story
The early public record is told largely through Amsterdam coffeeshops and the Cannabis Cup. In 1995 the Greenhouse coffeeshop won a Cannabis Cup with Kali Mist grown by Serious Seeds1. In 1996 the Dampkring, another well-known Amsterdam coffeeshop, took the Overall Cup with White Russian, then the company's newest strain1. In both cases the award went to the shop, with Serious Seeds credited as the source of the plants.
One date is awkward. The Seedfinder profile says AK-47 and Chronic won prizes at the Cannabis Cup in Amsterdam in 1994, which it places in the period of the earlier American venture, before the stated 1995 founding1. A different year from another source was also noted but could not be confirmed. Until a clearer record turns up, the timing of those first prizes is best treated as uncertain.
03Culture and Philosophy
The profile describes a long-standing policy of making the products grown from the company's seeds available to sample in a number of leading Amsterdam coffeeshops1. The Greenhouse is described as having carried Serious products since the start in 1995, with no end date given1.
The same profile names Blue Bird, from the early days, and more recently Dread Rock as shops that genuinely sell the strain on the menu rather than substituting something under a popular name1. The sources offer no further statement of the company's philosophy.
04Where Things Stand Now
The Seedfinder profile says Serious has always been a small company and intends to remain one1. The page gives no date for that statement, so it is best read as a general description of the company's outlook rather than a dated update.
Seedfinder's database lists 17 Serious Seeds strains, 13 of which have user reviews with an average rating of 7.7 out of 101. The catalogue includes AK-47, Bubble Gum, Chronic, Kali Mist, Serious Kush and White Russian, along with autoflowering versions of AK-47 and White Russian1. The page shows no date for these counts. No official company history was available, and the company's current operating details are not documented in the sources used.
