Home / What you receive

One serial, one farm, one season.

A certificate arrives within a day of sponsorship. The verified report follows the harvest, which means the summer after the metres go in the water. Both carry the same serial, and the serial resolves to a public record of that rope.

The report behind it

What the certificate is the cover of.

The annual report is where the detail sits. It is the part that takes a year, and the part most sponsorship schemes leave out.

Your rope

  • Line number, seeding date, lift date
  • Fresh weight per metre against the farm mean
  • Photographs of your section at lift
  • What the season did, including the bad weeks

The water

  • Species recorded on and around the line
  • eDNA results, start and end of season
  • Habitat area attributed to your metres
  • Sea temperature and its effect on yield

The land

  • Which land farm took the harvest, and how far it went
  • Soil organic matter before and after
  • What the farmer changed as a result
  • Share of your payment that reached the coast
Timing

It is a slow product.

There is one growing season a year and the kelp sets it. It seems better to be clear about the wait than to build a dashboard that updates daily and says little.

October to December

The following summer

Verified annual report, reviewed by an independent academic partner before it goes out.

Pick a coast. Put a rope in it.

One metre as a gift, or twenty thousand across the regions your business touches. Same model either way.
