The team covers how this method breaks dependency on wild source timing, reduces contamination, and significantly improves seed quality and yield for regenerative ocean farmers. GreenWave and Hortimare share their collaborative journey developing affordable, replicable, and scalable protocols for building gametophyte seed banks and propagating seed string. Chapters: 00:00 - Introduction Overview of GreenWave's kelp seed propagation approach using gametophytes 06:26 - Challenges in Traditional Seed Production Late and low-quality seed issues affecting harvest timing and yield 20:47 - Partnership with Hortimare How collaboration between organizations accelerated innovation 30:41 - Gametophyte Banking Benefits Controlling production timing, improving quality, and farm ownership of seed 48:01 - Q&A Session Detailed answers to technical questions about gametophyte culturing
