Overview: What Is Seed Supreme?
Seed Supreme is an international seed bank operating primarily from Europe, offering one of the most expansive strain catalogs in the industry at over 5,000 varieties from hundreds of breeders. It's been around long enough to accumulate a substantial customer base and a mixed-but-functional reputation.
The pitch is simple: if a strain exists, Seed Supreme probably has it. This is genuinely useful for collectors hunting specific genetics from boutique breeders, rare phenotypes, or legacy strains that smaller US-focused banks don't carry.
The practical reality for US buyers is harder: 7–4 day international shipping, the inherent customs exposure of any overseas shipment, and a customer service track record that's inconsistent depending on the situation. It works well enough for many buyers —but it's not the right choice for every grower.
Quick Facts
The 5,000 Strain Catalog
This is Seed Supreme's headline strength and it's genuinely impressive. The catalog covers feminized, autoflower, regular, CBD, and fast-version seeds from hundreds of breeders —including boutique operations that many US banks don't carry. Barney's Farm, Royal Queen Seeds, Fast Buds, DNA Genetics, Dinafem, and many more are all represented with deep catalogs rather than token listings.
For a collector building a seed vault, or a grower chasing a specific phenotype from a specific breeder, this depth is the main reason to use Seed Supreme over its competitors. You'll find strains here that simply don't exist at NASC or Multiverse Beans.
The flip side: with 5,000+ listings, quality control becomes harder to guarantee across the board. Reviews are inconsistent, and some breeders in the catalog have mixed community reputations. Stick to strains from established breeders you already trust.
Shipping & Delivery
This is the biggest practical limitation for US buyers. International shipments take 7–4 business days —real-world delivery often lands around 10–8 days once customs processing is factored in. That's 2– weeks minimum from order to receipt, compared to 2– days from NASC or Multiverse Beans.
Stealth shipping options are available, which reduces customs risk. Most orders arrive without issue —but "most" is not "all," and customs seizures do happen with international shipments. If your order is seized, Seed Supreme's reshipping policy depends on which shipping option you selected at checkout.
If timing matters —you have a grow window, a specific planting date, or you just don't want to wait —Seed Supreme is not the right bank. If you're planning months ahead and hunting specific genetics that aren't US-stocked, the wait is manageable.
Payment Methods
Multiple payment options work in Seed Supreme's favor —credit card processing is available and generally reliable for international seed purchases. Bitcoin discounts are offered and worth using if you're comfortable with crypto.
Germination Guarantee
Seed Supreme does not offer a formal germination guarantee in the same way ILGM (100%) or Herbies (70%) do. This is a meaningful gap for less experienced growers who rely on that safety net. If seeds don't pop, your recourse depends on individual customer service interactions rather than a stated policy.
Experienced growers who reliably hit high germination rates through established methods will find this less important. Beginners should seriously consider ILGM or Homegrown Cannabis Co instead —the germination guarantee has real monetary and psychological value when you're starting out.
Customer Service
Seed Supreme's customer service reviews are the most polarized of any major seed bank. Many customers report smooth transactions with no issues —when orders arrive correctly and on time, there's nothing to complain about. But when problems arise, resolution can be slow or frustrating.
The Trustpilot score (~4.0/5) reflects this middle ground —not terrible, not great. NASC's 4.8/5 with 30,000+ reviews is a more statistically robust measure of consistent quality. For high-value orders or time-sensitive purchases, that gap matters.

Who Should Shop at Seed Supreme?
If you've exhausted NASC and Multiverse's catalogs and need genetics from a specific boutique breeder, Seed Supreme's 5,000+ strain depth is unmatched. Worth the wait if you know exactly what you're after.
For non-US buyers where US-based banks don't offer an advantage, Seed Supreme's worldwide shipping and broad catalog make it highly competitive.
No germination guarantee, 7–4 day shipping, and inconsistent service make this a poor choice for first-time growers. Use ILGM or Homegrown instead.
For Mephisto, Night Owl, and top autoflower breeders, NASC and Multiverse Beans have domestic stock with 2– day shipping and no customs exposure. No reason to wait 2+ weeks for the same genetics.
Final Verdict
Seed Supreme earns its place in our rankings on the strength of its catalog alone. If sheer variety is your priority and you're an experienced grower willing to wait 1– weeks, there's no larger commercially available selection. For that narrow use case, it delivers.
For most US growers —especially beginners, autoflower hunters, and anyone who values fast domestic shipping —NASC, Multiverse Beans, or ILGM are better fits. Seed Supreme sits at #5 in our rankings: recommended for its specific strengths, not as a general-purpose recommendation.
