GreenWave’s polyculture farming system grows a mix of seaweeds and shellfish that require zero inputs—making it the most sustainable form of food production on the planet—while sequestering carbon and rebuilding reef ecosystems. Since our farms sit vertically below the surface, they produce high yields with a small footprint. With a low barrier to entry, anyone with 20 acres, a boat, and $20-50K can start their own farm.
