List of products by manufacturer Serious Seeds

Serious Seeds is one of the longest established seed companies in the Netherlands, specializing in the production of high quality, stable and consistent cannabis seed varieties. Producing high-quality cannabis strains for medical and recreational purposes is our top priority. Independent and reliable laboratory tests (over 20 years of experience in this field) have shown that the different strains of Serious Seeds produce the strongest plants (with the highest THC content) available on the market today, averaging between 18 -22% THC. These tests were performed on plants grown from the same seeds received from the customer. For most of our strains, stable plants are crossed to produce the vigorous F1 hybrids we sell. You can be assured of good germination and uniform plants, we also guarantee the germination of our seeds. Serious Seeds are produced in small quantities and are always fresh and hand selected. We test each batch of seeds for germination rate and uniformity of the resulting plants before releasing.
