Best Cannabis Seed Banks in the World

Choosing a source for your cannabis seeds is a critical first step in the grow process. Without a trustworthy source of safe and quality seeds, you are working under uncertainty. If you are a novice grower, do your homework and compare the highest rated cannabis seed breeders. A more stable genetic history means consistent, high-quality results. Genetically superior buds are denser and their glands produce more resin. Modern genetics have allowed for record crop yields and a more intense psychoactive effect. While some seed banks have long-held reputations for high-quality product, many are just beginning with all new genetics. Though several small-scale seed banks are located throughout the United States and Canada, many of the most popular breeders are located in Europe.

About Seed Banks: Feminized Seeds, Regular Seeds, and Auto-flowering Seeds

Before you decide on a particular breeder, it is important to understand the different varieties of cannabis seeds available.

When growing with traditional “regular” seeds, one male plant is bred with one female plant. Offspring produced will be either male or female. Feminized seeds have been engineered to eliminate the male chromosomes, ensuring only female offspring are produced. Feminized seeds are your best option in many cases, but regular seeds are better for certain cannabis strains.

Auto-flowering cannabis seeds do not require the same cycles of light and darkness as regular seeds. Even if they are constantly exposed to light, they will start to flower automatically when the plant reaches a certain stage of maturity. These crops come to full maturity in just under ten weeks. This means you can nearly double your yield within a single season.

We will look at some of the best-rated seed cannabis seed banks in each region. Another great resource you’ll want to check out is the Royal Seed Bank, where you can compare seeds and more.
