Seeds are an essential part of growing cannabis. Even established commercial companies that grow from clones have an ongoing need for seeds in order to create and introduce new proprietary strains. A major percentage of home growers always grow from seed, and this reality resulted in the establishment of numerous seed banks and seed brokers years ago. The number of seed banks has only expanded over the years, answering the demand for exclusive cannabis genetics in the United States and other countries.

While Amsterdam reigns supreme as the capital for seed banks, many of their genetics originally came from the U.S., which creates an interesting situation. In order to gain access to these once-American strains, U.S. consumers ironically have to obtain them from Dutch suppliers. With cannabis laws becoming increasingly progressive in the U.S., an increasing number of legal options are now becoming available to seed seekers in the states. Seed banks and brokers are springing up with increasing regularity on this side of the pond, specifically serving the needs of American growers—while some European seed companies (not all) specifically serve the needs of the European market.

Occasionally, you will find strains marketed in both Amsterdam and America that have the same name and genetic background but are dramatically different. Skunk #1 is an excellent example. While the American Skunk #1 reflects its name and has a dank, skunky quality, the Dutch version is sweet, with no trace of the skunky aroma. Dutch breeders have selectively bred Skunk #1 to appeal to the Dutch palate, while American breeders have retained its skunky qualities, which many Americans love. This creates a different take on the same strain. Several other Dutch skunk strains have a sweet quality as well.

How Are These Businesses Different?

Although various seed companies don’t always call themselves seed banks and brokers, and market themselves as such, people who are seeking good cannabis genetics often rely on them to get seeds. While both types of companies sell seed, they are decidedly different.

Seed companies do their own breeding to create new strains they market in seed form. Through selective breeding and growing, they identify the best phenotypes and stabilize the strains—although some strain releases may have a few known phenos that can occur in a single pack of seeds. Seed companies strive for consistency so their buyers know what to expect and gain trust in them as a source for potent, flavorful cannabis. Most seed banks sell their own seeds, sometimes only at their main place of business, as well as well as distribute them through seed brokers. To confuse things further, some seed companies market their seeds under more than one name, or occasionally sell seeds from partner companies.

Seed brokers do not create seed. Rather, they market seeds from various seed companies and banks, and they may have seed available from a diverse assortment of different seed creators. Many seed companies depend on seed brokers to market their product. Unlike some seed banks, most seed brokers will mail seeds worldwide, while some seed banks will only sell within their own country or to select countries. Price doesn’t always dictate quality. There are some seed companies and banks that sell very high-quality seeds at reasonable prices. The highest-priced strains are often new and highly anticipated releases, as well as old classics that are in high demand.

The seeds that these companies ship are sent in protective, discreet packaging. Some places will let you choose to remove seeds from a breeder’s packaging. Then, they are placed in collectible souveniers such as tote bags, pens, toys, DVD cases, and more to avoid detection. Most of them ship orders in a very timely manner. Seed buyers should research and educate themselves about the legality of shipping cannabis seeds to their locations and place orders armed with that knowledge.

Let’s take a look at a variety of seed businesses, both seed banks and seed brokers. Quite a few American cannabis breeders have migrated to Europe to do business—especially in the days when cannabis prohibition was nationwide in the U.S. Since marijuana is now legal in many parts of America (U.S. and Canada), there is cross-traffic, with Europeans coming to America as well.

As far as some of the more prominent seed businesses, an online search will reveal many more for those who are shopping for seeds. If a specific seed company will not ship to your location and you have a strong desire to grow one of their strains, chances are good that a seed broker will send you the same seed strain, from the exact company that created it, with packaging to prove it.

Since the mid 1980s, seed banks have popped up all over the world. When choosing between seed banks and brokers, consider the company’s years of experience. Most companies list the year they were founded on their “About Us” page. If not, do a little digging by searching Google for the seed bank name + “founded,” “established,” or “started.”

Before checking out, read the seed bank’s return and refund policy. While there are many reputable seed banks out there, their refund policy varies. It’s better to buy from a bank with an ironclad guarantee to protect you from getting bad seeds. Most seed companies will refund any item you are not happy with. Make sure you read the fine print and contact them within a certain number of days of receipt of your order.

Nowadays, seed banks and brokers allow you to pay with a host of methods including credit and debit cards, cryptocurrency, bank/wire transfers, check/money order, and good old cash. Choose a supplier that offers credit card, wire transfers, and e-wallet services. These payment modes protect you in case the supplier won’t help you.
