Buy Cannabis Seeds Online from a US Seed Bank
Oaseeds USA is an online cannabis seed bank that brings together genetics from 17 breeders, from European names like Royal Queen Seeds, Dutch Passion, Sweet Seeds and Barney’s Farm to US breeders such as Humboldt Seed Company and Ethos Genetics. Every strain page lists the breeder’s own data (genetics, flowering time, yield and aroma) so you can compare marijuana seeds side by side and pick the right ones for your space, climate and experience.
Orders ship from our warehouse in California. They are usually processed within 2–3 business days, packed discreetly and sent with USPS Ground or USPS Priority Mail, with a tracking number for every shipment.
Feminized, Autoflower and Regular Weed Seeds
- Feminized seeds grow only female plants, the ones that produce flowers. They are the first choice for most home growers who want every plant to count.
- Autoflower seeds flower on their own, without a change in light schedule, and usually go from seed to harvest in about 8 to 12 weeks. Great for beginners, small spaces and several outdoor runs per season.
- Fast flowering seeds (F1 Fast Versions) are photoperiod plants bred to finish one to two weeks earlier, ideal for short summers.
- Regular seeds give a natural mix of male and female plants, the classic option for breeders, pheno hunters and anyone making their own crosses.
- CBD seeds produce strains with high CBD and low to moderate THC, for growers who want a milder, more balanced profile.
How to Choose the Right Cannabis Seeds
Start with where you will grow. Indoors, compact indica-leaning strains and autoflowers make the most of a tent. Outdoors, check the breeder’s harvest window against your first fall frosts and pick mold-resistant genetics if your autumns are wet. Then look at flowering time, expected yield and the aroma family you enjoy, from fruity and dessert terps to classic gas, Kush and Haze. If you are new to growing, autoflowers and strains marked as easy are the safest start; experienced growers can chase the high-yield, long-flowering sativas and the latest hybrids.
Every pack ships from the same US store, so you can mix weed seeds from different seed banks in a single order and compare genetics in your own garden.
Cannabis Seeds FAQ
Where do you ship cannabis seeds from?
All orders ship from our warehouse in California, USA. Orders are usually processed within 2–3 business days and sent with USPS Ground or USPS Priority Mail, with tracking.
Are the seeds shipped discreetly?
Yes. Every order is packed discreetly and securely, and you receive a tracking number as soon as it ships.
What is the difference between feminized and autoflower seeds?
Feminized seeds grow female plants that need a 12/12 light schedule to flower. Autoflower seeds are usually feminized too, but they flower on their own after a few weeks, whatever the light schedule, and finish faster.
Which cannabis seeds are best for beginners?
Autoflowers and feminized strains described as easy to grow are the simplest place to start. They forgive small mistakes, stay compact and finish quickly. Each product page lists the breeder’s difficulty level, flowering time and expected yield.
Can I order seeds from different seed banks in one order?
Yes. Oaseeds USA stocks 17 seed banks and breeders in one store, so you can combine packs from different brands in a single order and a single shipment.
