A cannabis seed bank germination guarantee is a written promise that the seller will replace or refund seeds that fail to sprout within a set window, usually 7 to 14 days after delivery, as long as you germinated them using the method the policy names. It is a store policy and a contract term, not a legal right, so the exact coverage differs from one seed bank to the next. Read the policy before you drop seeds in water, because most claims are denied for procedural reasons rather than bad seeds.

What does a germination guarantee actually cover?
Most guarantees cover seeds that never crack a taproot or that stall after the shell splits. The standard remedy is replacement seeds of the same strain, followed by store credit. Cash refunds are the least common outcome and often apply only when the strain is out of stock.

Coverage usually applies per seed or per pack, and many banks set a minimum failure rate, such as 50 percent of a pack, before they act. Higher-end breeders sometimes offer a longer window than budget white-label packs.

How long is the claim window?
Seven to fourteen days from the delivery date is typical, though some banks extend it to 30 days for photoperiod regular seeds. The clock usually starts on the carrier's confirmed delivery scan, not the day you started germinating.
Late claims are the single most common reason a guarantee gets refused. Set a reminder for day 10 so you still have room to document and submit.
What voids a germination guarantee?
Policies list exclusions to separate grower error from non-viable seed. Common disqualifiers include:
- Soaking in bleach, hydrogen peroxide, or any solution the policy forbids
- Using a paper towel or glass-of-water method when the policy requires direct sowing into medium
- Germinating outdoors, in a cold garage, or below the stated temperature range
- Crushing, cracking, or scraping seeds by hand
- Submitting a claim without photos, video, or the original order number
- Shipping to a state or country the bank lists as restricted
Yields, potency, hermaphrodites, and phenotype variation are almost never covered, because those depend on grow conditions and genetics beyond germination.
How do you file a germination claim?
- Contact support before the deadline through the channel the policy names, usually email or a ticket form.
- Include the order number, strain name, pack size, and the date the seeds arrived.
- Attach clear photos or a short video of the failed seeds and your germination setup.
- Describe your method, water source, temperature, and how many days you waited.
- Accept the offered replacement or credit, and return the failed seeds if the bank asks.
Banks that ask for returns typically reimburse shipping or bundle extra seeds to offset it. Keep the original packaging until the claim closes.
Are germination guarantees legally enforceable?
In the United States, a germination guarantee is a seller's own policy, and the Federal Trade Commission's mail order rule requires sellers to ship within the stated time or offer a refund when they cannot. That rule backs your order, not your seedlings, so the guarantee itself remains a customer service promise.
Hemp genetics are federally legal under the 2018 Farm Bill, but state cannabis laws vary widely and some banks will not ship to certain states at all. A restricted shipment can void the guarantee even if the seeds never sprout.
How do you protect your guarantee?
- Photograph the sealed pack and the seeds on arrival, before storage.
- Follow the breeder's germination method exactly, not a forum shortcut.
- Hold temperatures between 70 and 85 degrees Fahrenheit and use clean, low-mineral water.
- Handle seeds with tweezers or clean fingers, never rough abrasives.
- Log start dates so you can prove you stayed inside the window.
Feminized and autoflower seeds can be more sensitive to stress than regular seeds, so a gentler approach helps you avoid a claim altogether.
