Serious Seeds are a small firm, concentrated on the production of high-quality varieties of cannabis seeds.
Lab tests have shown that the Serious Seeds strains produce some of the strongest plants (highest in THC content) available on the market today, averaging between 18 - 22% THC.
Every batch of seeds is tested for germination rate and uniformity of the plants before releasing it. Every bag is numbered; keep the original package and the number in the highly unlikely event of a problem. Why are there only five strains in the Serious line?
To keep quality high, Serious Seeds only release a seed strain once it is stable and consistent. Strains have been improved through good selection; when a strain is improved, this is sold with the same name.
