Seed Exchange.

Grower to grower, one variety at a time.

Every season, growers end up with more seeds than they can sow. Capsi’s Seed Exchange turns that surplus into a community. If you’re growing a variety, you can offer your spare seeds to other members — and when you’re hunting for something specific, you can find growers who have it and reach out directly.

Capsi is the matchmaker, not the middleman: we introduce two growers and give them a private space to talk. How the seeds change hands — a trade, a gift, postage — is entirely between you. There’s no checkout, no fees, no shipping to manage in the app.
