Developing a Biodegradable Controlled‑Release Fertiliser

Dr. Russell Sharp discusses manufacturing chitosan biofungicide and announces a lab breakthrough creating a biodegradable alternative to Osmocote, driven by concerns over microplastics and corporate practices.

The episode covers trials showing hemp matting outperforms coco coir for microgreens, a failed cardboard grow‑media test, resilient ebb-and-flood clay bead trials, and planning considerations for a hydroponic shipping container.

Additional notes include observations on Israeli agricultural land ownership, a European HGV driver shortage, an anecdote about Dr. Dre and 'chronic', and a promise to highlight positive hydroponic work from Israel in a future episode.
