How we choose our seed banks
We don’t list every brand out there. A seed bank has to earn its place in our catalog.
Proven genetics
Breeders with a real track record: decades-old houses with famous originals, and newer teams whose strains growers keep coming back to.
Clear lineage
We favor seed banks that tell you what is inside the pack: named parents, honest flowering times and realistic yields.
Stable, reliable seeds
Consistent germination and uniform plants matter more than hype. Unstable lines don’t make the cut.
Something for every grower
Feminized, autoflower, regular, CBD and bulk options, so beginners and experienced breeders both find what they need.
Why buy from a US-based seed bank?

Orders are prepared in 2–3 business days. Then they ship with USPS Ground or USPS Priority Mail, and you get a tracking number as soon as your package leaves. See shipping information.

Frequently asked questions
Which seed bank is best for beginners?
Look for forgiving, well-known strains rather than a specific brand. Autoflowers and classic feminized strains from established houses like Dutch Passion, Barney’s Farm or Sweet Seeds are a good place to start because they are stable and well documented.
What is the difference between feminized, autoflower and regular seeds?
Feminized seeds produce female plants that flower when you change the light cycle. Autoflowers are also feminized but flower on their own after a few weeks, so they are faster and more compact. Regular seeds give both male and female plants and are mainly used by breeders.
Are the seeds genuine?
Yes. We only sell original packs from the seed banks listed on this page. We do not repackage or relabel seeds.
Do you ship outside the United States?
No. OaseedsUSA.com ships only within the United States. For international orders, visit our main store at oaseeds.com, which ships worldwide from Europe.
How long does delivery take?
Orders are prepared in 2–3 business days. After dispatch, USPS Priority Mail usually takes 1–3 business days and USPS Ground 2–5 business days.
