Seed bank reviews
Where the seeds actually come from
Independent seed-bank reviews built on six criteria that actually predict whether a home grower ends up with viable seed in hand. We buy our own packs and read the policy small print rather than rewriting marketing copy. One affiliate partner, two informational references.

How we evaluate
Six criteria, in order of decisive impact
A guarantee means nothing if the bank doesn't ship to your state, so shipping is checked first. Full criteria + editorial process are documented on the methodology page.
Shipping coverage
Which countries and US states does the bank actually ship to, and how is the parcel packaged once it leaves.
Germination guarantee
Exact wording, what triggers a replacement, and how long the bank has to make good on a failed pack.
Catalogue depth
How many breeders are represented, how often the catalogue rotates, and whether the named breeder of record actually matches what ships.
Payment options
Cards, bank transfer, cash by mail, crypto — and which of those US growers can actually use without a workaround.

Editorial posture
Why ILGM is the only affiliate link on this site
Lockbox publishes editorial reference material on cannabis seed banks rather than push-to-cart copy, and that posture is structurally tied to the affiliate model we operate. ILGM is the single disclosed commercial partner on this site, chosen for documented US shipping coverage, unconditional germination guarantee, and a 90-day affiliate cookie window long enough to support independent coverage. The Seedsman and Royal Queen Seeds reviews are informational — those banks are not Lockbox commercial partners, no outbound links to them exist anywhere on the site, and the reviews are published for completeness so a reader comparing options has a reference that is not marketing copy from either bank.
