Dr. Russell Sharp examines whether warm‑climate perennials like avocados can be grown economically indoors in cold countries. He reviews a Norwegian research trial using waste heat, cheap hydroelectric power, LED greenhouses, and micropropagation to produce local avocados, and discusses pollination, growth timelines, and energy costs. The episode weighs the trade-offs between long production times and local quality/supply benefits, shares practical hydroponic lessons, and invites listeners to share unusual crops they’ve grown. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/   Yara   Oslo Jonas Gahr Støre Erna Solberg  Jens Stoltenberg Erling Haaland Martin Ødegaard Ole Gunnar Solskjær John Arne Riise Svalbard Agrinos Nobel Prize Jo Nesbø Edvard Munch
