About this episode
Dr. Russell Sharp discusses the struggle of the UK and European hydroponic sector, focusing on recent enforcement in the Netherlands over continuous in-line dosing of hydrogen peroxide. He explains why regulators flagged the practice, the science behind peroxide breakdown, and his frustration with overly rigid enforcement. Russell also offers practical advice: avoid continuous peroxide dosing to protect roots and yields, keep systems clean, and use peroxide sparingly. He reflects on the wider impact of regulation on innovation and shares how his company adapts to EU rules. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ Matthew Appleby — Horticulture Week Sally Drury — Horticulture Week Gavin McEwan — Horticulture Week Clare Foggett — The English Garden Vivienne Hambly — The English Garden Sue Fisher — BBC Gardeners’ World Magazine Emma Crawforth — BBC Gardeners’ World Magazine Kevin Smith — BBC Gardeners’ World Magazine Miranda Janatka — BBC Gardeners’ World Magazine Kay Maguire — BBC Gardeners’ World Magazine Daniel Haynes — Gardeners’ World Catherine Mansley — Gardeners’ World Sonya Patel Ellis — Gardeners’ World Kate Bradbury Greg Loades Veronica Peerless — Gardens Illustrated Kate Jacobs — Gardens Illustrated Tim Richardson — Gardens Illustrated Alys Fowler Jane Perrone Alexandra Campbell Alice Vincent Alice Lascelles — Financial Times Tom Heap — BBC James Wong Val Bourne Anne Swithinbank Bob Flowerdew Mark Diacono Cleve West Sarah Raven Annie Guilfoyle Andrew Timothy O’Brien Jonathan Buckley Tamsin Hope Thomson Nic Wilson Kim Stoddart — Amateur Gardening Alan Titchmarsh Monty Don Carol Klein Joe Swift Pippa Greenwood Paul Green Noel Kingsbury Marian Boswall Jack Wallington Alice Bowe Jane Courtier Rachel de Thame Lucy Chamberlain Carolyne Roehm Noel Kingsbury Nigel Slater — The Observer Anna Pavord Penelope Lively Beth Chatto Christopher Lloyd Vita Sackville-West Gertrude Jekyll Margery Fish Dan Pearson Tom Stuart-Smith Armitage Shanks (No, wrong) Toby Buckland Fergus Garrett Sarah Cuttle Lia Leendertz Matthew Biggs Peter Seabrook Bunny Guinness Alice Doyle Jamie Butterworth — RHS Guy Barter — RHS Helen Yemm — The Telegraph Jane Moore Debora Robertson Mary-Kay Wilmers Emma Townsend Jessica Damiano — Associated Press Adrian Higgins — The Washington Post Margaret Roach Ken Druse Jeff Lowenfels Doug Oster — Pittsburgh Post-Gazette Maria Rodale Danielle Sherry — Fine Gardening Jeremie Fant — Fine Gardening Caitlin Boyle — Fine Gardening Erin L.
