Short answer
A cannabis seed bank stores and sells cannabis or hemp seeds. A good one publishes third-party lab results for the parent plants, states in writing which seed category it sells, ships with tracking, and backs germination with a written policy. A poor one hides its sourcing, prints THC numbers no lab verified, and refuses refunds. Decide what you want first, whether that is hemp genetics for CBD or high-THC cultivars, then judge vendors on documentation instead of photos and hype.
Where the legal line falls
Under federal law, cannabis seeds are Schedule I material when the plant crosses the hemp threshold. Hemp seed, defined as Cannabis sativa L. with delta-9 THC at or below 0.3 percent on a dry weight basis, sits outside the Controlled Substances Act. That split drives shipping rules. A vendor in one state may send hemp seed to a customer in another state while the same shipment of high-THC seed fails to qualify. Read your state statutes before you order, and read the vendor shipping restrictions page before you pay.
Prerequisites
- Your state seed and hemp statutes, checked on the state legislature site.
- A target: CBD hemp genetics, high-THC cultivars, or autoflowering types.
- A storage plan: airtight container, dark location, 32 to 41 degrees Fahrenheit, low humidity.
- A budget that covers seeds, shipping, and any phytosanitary certificate for imports.
How to vet a seed bank, step by step
- Confirm the seed category. Ask the vendor to name the lot as hemp seed or cannabis seed in writing. A vague answer ends the conversation.
- Ask for the certificate of analysis. Look for the lab name, the sample date, the cannabinoid panel, and the batch number that matches your lot.
- Check the germination guarantee. Note the germination window, the refund percentage, and whether you must photograph the failed seeds.
- Review shipping terms. Confirm the destination states, the packaging, the tracking, and the replacement policy for seized orders.
- Inspect the payment options. Reputable vendors use processors that disclose chargeback rights. Wire-only payment with no recourse is a warning sign.
- Ask how seeds are stored. Breeders who keep stock in climate-controlled rooms preserve viability better than vendors who store stock at room temperature.
- Search for complaint patterns. Read reviews on independent forums and look for repeated reports of mold, crushed seeds, or missing orders.
- Test customer service before you buy. Send one question about genetics or shipping and note the response time and the depth of the answer.
Red flags
- No physical address or business registration.
- THC or CBD percentages with no lab report attached.
- Claims that seeds cure or treat disease.
- Prices far below the market for named cultivars.
- No stated policy on customs seizures or failed germination.
How to store seeds after they arrive
- Leave the seeds in the original labeled vial.
- Add a desiccant packet if the vial does not include one.
- Seal the vial in an airtight glass jar.
- Place the jar in a refrigerator that stays between 32 and 41 degrees Fahrenheit.
- Label the jar with the cultivar name and the purchase date.
- Open the jar only when you plan to germinate.
FAQ
Are seed banks the same as breeders?
No. A breeder develops and stabilizes genetics. A seed bank resells those genetics, sometimes alongside its own line. Ask whether the vendor produces the seed or buys it from a third party.
Do lab reports on seeds prove CBD content?
Not on their own. Cannabinoid content in the finished plant depends on genetics plus growing conditions. A seed lot report shows the parent material, and a flower report from your own harvest shows what you grew.
Can I buy seeds from another country?
Import rules vary. Some shipments require a phytosanitary certificate, and customs officials may hold or destroy seed that does not meet the rules for your state. Check with your state department of agriculture before you order from abroad.
