A cannabis seed bank sells seeds. Some also breed them. That difference matters. Breeders make seed from parent plants and control the genetics. Resellers buy wholesale and list the stock. A reseller that names the breeder, the generation (F1, S1), and the harvest date is easier to check than one that does not.
Top Outdoor Cannabis Seeds: How to Choose for Sale
Check legality before you pay
Federal law allows hemp seed. The 2018 Farm Bill defines hemp as Cannabis sativa L. with 0.3% or less delta-9 THC by dry weight, and that definition covers seed. Seed carries almost no delta-9 THC. The plant grown from it does. State law governs possession and cultivation where you live. Some states restrict seed. Check your state code and local rules. Shipping addresses and payment records leave a trail.
Parameters to compare
Seed type
- Feminized: about 99% female plants. Higher price. No males to cull.
- Regular: about 50% male, 50% female. Cheaper. Needed for breeding.
- Autoflower: flowers on a timer, not on light cycle. Cycle runs 70 to 90 days from seed.
Documentation
Look for breeder name, lineage, generation, and a lot or harvest date. Strong listings give flowering time in weeks and expected yield. A listing with no breeder and no date is unknown stock.
Cannabis Seeds for Sale Review: A Comprehensive Buying Guide
Price
Single feminized seeds run $10 to $20. Three-packs run $30 to $60. Ten-packs of breeder stock run $60 to $150. Below $3 per seed points to white-label bulk seed with no traceable parent.
Payment and shipping
Card networks restrict cannabis. Many banks take cards through a third-party processor, or take bank transfer, cash, or crypto. Tracked shipping with a replacement policy costs more and is worth it. Ask for dispatch time in business days.
Germination terms
A stated rate of 90% or higher on fresh photoperiod seed is standard. Read the terms. Many banks void the guarantee if you germinate in water, or if you do not contact them inside a set window, often 14 to 30 days.
Pitfalls
- No physical address. Contact is a web form only.
- Stock photos instead of the breeder's packaging.
- Guarantees that require you to ship live plants back.
- Reviews on one site only, all posted in the same week.
- Prices far below market for named breeder lines.
After delivery
Seed keeps best at 6% to 8% moisture, in the dark, at 5 to 10 C. A sealed jar in a refrigerator holds viability for several years. Room temperature and humidity cut that to 1 to 3 years. Label the jar with strain and date.
Order timing: European banks ship to the US in 5 to 15 business days, and customs adds delay. Domestic banks ship in 2 to 5. Buy before your grow window opens, not during it.
