These Are The Champions
Serious Seeds is a small firm concentrating on the production of high-quality, stable and consistent varieties of cannabis seeds. 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 the costumer gets.
For most of their strains, stable plants are crossed to produce vigorous F1 hybrids that they sell. You can be assured of good germination and uniform plants. Serious Seeds are produce in small numbers and are always fresh and hand selected.
