Serious Seeds is one of the longest established seed-companies in Holland, concentrating on the production of high-quality, stable and consistent varieties of cannabis seeds.

The production of top quality cannabis-strains for medical and recreational purposes are their 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.

They are the ONLY company to individually number our packages, so every seed can be followed from production to the point-of-sale in the shop.
