Finding a trusted cannabis seed bank isn’t easy, but Seed Supreme helps make the process more straightforward. With discreet shipping and a massive selection, it’s become a popular choice for growers around the world.
Seed Supreme is a UK-based online seed bank that offers over 4,000 cannabis seed strains from more than 100 expert breeders. Their catalog includes feminized, autoflower, and regular seeds, ranging from high tetrahydrocannabinol (THC) and high cannabidiol (CBD) to high-yield varieties and hybrids.
While cannabis laws vary by country and state, Seed Supreme operates within legal boundaries by selling seeds as souvenirs. Because they are based in the UK, where cannabis cultivation is restricted without a license, they cannot encourage germination. However, purchasing from them remains legal in most areas under souvenir laws.
To protect buyers, Seed Supreme offers stealth shipping and secure checkout. This adds peace of mind for customers in regions with stricter laws.

Seed Supreme Products
Seed Supreme offers a wide range of cannabis and hemp seeds, organized into several key categories. Each category contains hundreds of different strains, giving growers plenty of options to explore.
Before you start adding seeds to your cart, it’s helpful to know which type fits your growing goals and preferences. Understanding these categories will make selecting the right seeds easier and more effective.
Feminized Seeds
When we tested feminized seeds from Seed Supreme, we noticed a big difference right away. Every plant in our grow turned out female, just as promised. That meant no time spent checking for male plants and no risk of accidental pollination ruining our harvest.

Feminized seeds gave us more control and saved us effort. We didn’t need to learn how to sex the plants, which is helpful if you’re still new to growing. Plus, since every plant was female, all our space went toward producing buds, not wasted on male plants.
The only catch? You can’t use these plants to breed your next batch unless you introduce a male. But if you’re focused on yield and simplicity, especially in small spaces, feminized seeds are the way to go.
Autoflower Seeds
When we tried autoflower seeds from Seed Supreme, we were honestly impressed with how simple the process was. These seeds started flowering on their own, without us needing to change the light schedule or mess with any advanced techniques.

That made them a great option for our newer growers on the team. We didn’t need to worry about timing the switch from veg to flower. The plants just knew what to do.
We also liked having the option to slowly adjust the light exposure. It gave us a bit more control and let us fine-tune the grow without stressing the plants. The built-in timer feature of autoflowers saved us time and energy. Everything moved faster, and harvest came sooner than expected.
Medicinal Seeds
When we explored the medicinal seeds section on Seed Supreme, we were surprised by how many options there were. Whether you’re dealing with chronic pain, anxiety, or more specific conditions (i.e. fibromyalgia or Parkinson’s), there’s likely a strain made to help manage those symptoms.

We’re not saying cannabis is a cure. But from our experience, the right strain can make a big difference in how symptoms feel daily. For example, high-THC strains gave strong pain relief during our test grows. On the other hand, high-CBD strains helped ease tension and inflammation.
We also liked being able to mix and match different strains based on needs. It gave us more flexibility to experiment and find what worked best. And yes, our Seed Supreme coupon codes worked all our choices.
Regular Seeds
We decided to test out regular seeds from Seed Supreme to see how they stack up. These are as natural as it gets; no genetic tweaks, no guarantees on sex. Just a straight mix of male and female seeds, like you’d find in the wild.

If you’re into breeding, regular seeds are the way to go. We used them to experiment with creating our own strains, and they gave us more flexibility than feminized or autoflower seeds.
They’re also much easier on the budget. Regular seeds cost less, and we found them to be tougher overall. They handled stress better during our grow and were more resilient in shifting conditions.
The tradeoff? You’ll need to know how to spot and remove the males before they pollinate the females. That took more time and attention, especially for our newer growers.
Why We Love SeedSupreme
Seed Supreme stands out as one of the most versatile seed banks online. But what sets them apart isn’t just the size of their catalog; it’s the quality and sourcing of their seeds.
Product Selection and Genetics
Seed Supreme offers seeds from well-known breeders with a strong reputation for consistency. Their catalog includes strains with stable genetics, which is a major plus in an industry where reliability can vary. This variety gives both beginners and experienced growers a lot to work with.
