Cannabis seed banks are catalog-based suppliers that store, document, and ship cannabis and hemp genetics, including the CBD-rich cultivars many wellness shoppers look for. A dependable seed bank tells you the cultivar name, its lineage, its expected cannabinoid profile, and whether the parent stock was tested. This guide covers what to check before you place an order so your first purchase is an informed one.
What should you check first?
Start with documentation. Look for a listed cultivar name, type, and cannabinoid expectations, plus a clear statement of whether the genetics are hemp or high-THC cannabis, since the two carry different legal status in the United States.
Key Features
- Named cultivars with lineage, breeder, and generation noted in every listing
- Seed type clearly labeled: feminized, regular, autoflower, or photoperiod
- Reported CBD-to-THC ratios and cannabinoid expectations per lot
- Third-party lab certificates available on request for parent stock
- Germination guarantee or replacement policy stated up front
- Discreet, crush-resistant packaging with tracking on every order

What materials and specifications matter?
Quality seed banks pack seeds in amber glass vials or sealed foil pouches with a desiccant, which buffers against humidity swings in transit. Viability depends heavily on moisture and temperature, so store seeds in an airtight container away from light and heat once they arrive. Listings should also specify seed count per pack, breeder origin, and whether the stock is a stabilized line or a fresh hybrid, because those details shape how predictable the plants will be.
How do shipping and returns work?
Most reputable suppliers ship discreetly in plain packaging with tracking, and many restrict delivery to states where the genetics are permitted. Orders typically leave the facility within a few business days. If seeds arrive damaged or fail to germinate under the posted method, most banks offer a replacement or credit, so read the policy and keep your packaging and order number until the grow is underway.
Are cannabis seed banks legal in the United States?
Hemp genetics containing no more than 0.3% THC are federally legal, while high-THC cannabis seeds remain regulated at the state level. Check your state's rules before ordering.
How long do purchased seeds stay viable?
Stored cool, dark, and dry in an airtight container, most cannabis seeds keep well for a year or more, with germination rates declining gradually over time.
Can you buy seeds if you do not plan to grow?
Some collectors purchase seeds as novelty genetics only. If you do not intend to cultivate, confirm the supplier's terms, since many catalogs are intended for permitted growers.
