Dr. Russell Sharp explores the story behind cotton candy grapes, explaining how they were created through patient, traditional plant breeding rather than artificial flavouring or genetic modification. He describes the selection process, the natural flavour compounds involved, and the decade-long effort by breeders to bring this unique-tasting fruit to market. The episode also looks at research into breeding strawberries and other fruits for distinctive flavours, the role of modern genomic tools in speeding selection, and how these novel varieties could intersect with hydroponic and vertical farming systems. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ Sun World — John Harley International Fruit Genetics — David Cain SNFL — Jean-Luc Stalon Bloom Fresh — Chris Davey ARRA — Stefano Di Michele Sheehan Genetics — David Sheehan Grapa Varieties — Luca Fini Great Growers Partnerships — Jim Beagle Vine Genetics — Paul Boss CSIRO — Anthony Borneman USDA-ARS Parlier — David Ramming USDA-ARS Geneva — Bruce Reisch Cornell Grapes — Bruce Reisch UC Davis Viticulture & Enology — Andy Walker UC Riverside Grapes — Pat Brown Washington State University Grapes — Markus Keller Oregon State University Grapes — Patty Skinkis Michigan State University Grapes — Paolo Sabbatini University of Minnesota Fruit Breeding — James Luby University of Arkansas Grapes — John Clark University of Georgia Grapes — Patrick Conner Texas A&M Viticulture — Lorenzo Rossi North Carolina State Muscadine Breeding — Renee Threlfall Florida A&M Grape Breeding — Jeff Wasielewski Florida UF/IFAS Grapes — Peter Cousins Agroscope Grapevine Breeding — Andreas Hund INRAE Grapevine Breeding — Patrice This IFV — Thierry Lacombe University of Bordeaux Vine & Wine — Eric Boissenot UTAD — Henrique Ribeiro Instituto Superior de Agronomia — Antero Martins CREA Viticulture — Stefano Poni Fondazione Edmund Mach — Marco Stefanini Geilweilerhof — Reinhard Töpfer Hochschule Geisenheim — Hans Reiner Schultz Wädenswil Viticulture — Jürg Linde University of Milan Viticulture — Attilio Scienza University of Turin Viticulture — Anna Schneider University of Adelaide Viticulture — Paul Dry AWRI — Rob Walker University of Stellenbosch Viticulture — Gert Nieuwoudt ARC Infruitec-Nietvoorbij — Danie Myburgh Volcani Center Grapevine — Eyal Tanne INIAV — Antero Martins Embrapa Uva e Vinho — Murillo de Albuquerque Regina INTA — Walter Biasi Universidad Nacional de Cuyo Viticulture — Laura Catena Catena Institute of Wine — Alejandro Vigil University of Chile Viticulture — Patricio Hinrichsen Pontificia Universidad Católica de Chile Viticulture — José Bordeu Driscoll’s — Steve Nelson Plant Sciences — Doug Shaw Berry Genetics — Kirk Larson Lassen Canyon Nursery — Patrick Phillips California Berry Cultivars — Doug Shaw USDA-ARS Strawberry Corvallis — Kim Lewers UC Davis Strawberry Breeding — Doug Shaw UC ANR — Mark Bolda UF Strawberry Breeding — Vance Whitaker University of Arkansas Strawberry Breeding — John Clark North Carolina State Strawberry Breeding — Gina Fernandez Michigan State University Strawberry Breeding — Chad Finn Cornell Strawberry Breeding — Marvin Pritts Oregon State University Strawberry Breeding — Chad Finn Washington State University Strawberry Breeding — Chuck Brun University of Minnesota Strawberry Breeding — Jim Luby University of Wisconsin Strawberry Breeding — Craig Chandler Penn State Strawberry Breeding — Marvin Pritts Rutgers Strawberry Breeding — James Polashock University of Maryland Strawberry Breeding — Chris Walsh University of Massachusetts Strawberry Breeding — Jaime Pinero University of New Hampshire Strawberry Program — Becky Sideman Agriculture Canada Kentville — Andrew Jamieson University of Guelph Berry Breeding — Adam Dale Summerland Research — Hugh Daubeny NIAB EMR — David Simpson East Malling Strawberry Breeding — David Simpson James Hutton Institute — Louise Russell Wageningen Berry Breeding — Arnaud Wybou

Dr. Russell Sharp exposes a growing problem of fake plant listings and AI-generated seed scams on Amazon and other marketplaces, showing how buyers are being misled by impossible varieties (like bright blue hostas) and foreign drop-shippers. He explains how to protect yourself—check seller and nursery credentials, prefer reputable nurseries or local stores—and shares a real seed mix-up story to contrast honest mistakes with deliberate fakes. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ More reputable growers and seed sellers: Burpee — W.

Dr. Russell Sharp explains how melatonin — a molecule known for human sleep and stress regulation — is produced by plants and acts as a powerful antioxidant and growth regulator. In hydroponics it can enhance root growth, improve stress tolerance under high light or unstable conditions, delay leaf senescence, and support photosynthesis and secondary metabolite production. Applied as a foliar spray, seed priming, or added to nutrient solutions at micromolar concentrations, melatonin is water-soluble and allows precise dosing in soilless systems. Research shows benefits in crops like tomato and lettuce, with increased root-to-shoot ratios and higher antioxidant levels under stress. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ Russel Reiter — University of Texas Health Science Center Dun-Xian Tan — University of Texas Health Science Center Rakesh K.

Host Dr. Russell Sharp tackles a Twitter claim that hydroponic crops lack micronutrients and are artificially flavoured, explaining why those assertions are incorrect and how micronutrient levels can be measured (e.g., atomic absorption spectroscopy). He reviews research on manipulating flavor through nutrient levels, light, and biostimulants, notes the limited and mixed evidence, and concludes there is no solid proof of intentional artificial flavouring in hydroponic produce; soilless systems can match or even enhance some flavour-related compounds. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ Gary Reineccius — University of MinnesotaAndrew Taylor — University of NottinghamRussell Keast — Deakin UniversityCharles Spence — University of OxfordHarrison Schmitt — Virginia TechMorten Møller — University of CopenhagenJohn Hayes — Penn State UniversityQian Janice Wang — Aarhus UniversityMarcia Pelchat — Monell Chemical Senses CenterBarry Smith — University of London Linda Bartoshuk — University of FloridaPaul Breslin — Monell Chemical Senses CenterDanielle Reed — Monell Chemical Senses CenterBarry Green — Monell Chemical Senses CenterThomas Hummel — Technical University of DresdenAlan Hirsch — Smell & Taste Treatment and Research FoundationSusan Schiffman — Duke UniversityMolly Birnbaum — Freelance Food WriterHarold McGee — Freelance Food WriterKantha Shelke — Corvus Blue Tim Hanni — Master of Wine InstituteGeoffrey Talavera — Freelance Flavor ConsultantPeter Schieberle — Technical University of MunichThomas Hofmann — Technical University of MunichCorinna Dawid — Technical University of MunichVeronika Somoza — University of ViennaMorten Andersen — University of CopenhagenChristophe Lavalle — AgroParisTechStéphane Guichard — INRAEThierry Thomas-Danguin — INRAE Erich Leitner — Graz University of TechnologyHans-Georg Schmarr — University of HohenheimElke Pawelzik — University of GöttingenMichael Witting — Helmholtz Zentrum MünchenRalf Zimmermann — University of RostockFrancesco Capozzi — University of BolognaGiovanni Capuano — University of Naples Federico IIMaurizio Servili — University of PerugiaRosa Lo Scalzo — CREA ItalyPaolo Masella — University of Parma Fidel Toldrá — Instituto de Agroquímica y Tecnología de AlimentosMaría Dolores del Castillo — Spanish National Research CouncilDolores Coreta-Gomis — University of ValenciaJuan Fernández-García — University of GranadaAna Bayarri — University of ValenciaMarta Corredig — Aarhus UniversityMarina Heinonen — University of HelsinkiAnu Hopia — University of TurkuKees de Graaf — Wageningen University & ResearchGerry Barker — University of Leeds Jean-Marie Lehn — Max Planck Institute for Polymer ResearchWilfried Meyerhof — German Institute of Human NutritionMaik Behrens — German Institute of Human NutritionJohn Prescott — University of OtagoAnna M.

Dr. Russell Sharp examines a warning from the UK Urban AgriTech group that a planned 94% increase in electricity network standing charges from April 2026 could dramatically raise operating costs for vertical farms and greenhouses, risking business failures, reduced domestic produce and higher food prices. The episode explains how horticulture is excluded from the energy-intensive industries exemption, compares UK energy costs with EU competitors, and outlines how razor-thin margins make indoor growers particularly vulnerable; calling for urgent policy review and industry engagement. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ Leo Marcelis — Wageningen University & ResearchErik Runkle — Michigan State UniversityNeil Mattson — Cornell UniversityBruce Bugbee — Utah State UniversityRoberto Lopez — Michigan State UniversityChieri Kubota — Ohio State UniversityYoubin Zheng — University of GuelphToyoki Kozai — Chiba UniversityGenhua Niu — Texas A&M AgriLife ResearchA.J.

In this episode we examine why carnivorous plants and bonsai often struggle in coco grow media — coco (coir) can contain high sodium and is frequently buffered with calcium nitrate, resulting in elevated calcium and nitrogen compared with peat. The host suggests a fix: use raw high-sodium coco and flush it with Liquid Gypsum (calcium sulfate) to remove sodium without adding nitrogen, creating a peat-free grow medium suited to carnivorous plants and bonsai and a potential niche business idea. https://eutrema.co.uk/shop/soil-conditioners/liquid-gypsum/ Ryan Neil — Bonsai Mirai Bjorn Bjorholm — Eisei-en Bonsai Michael Hagedorn — Crataegus Bonsai Peter Chan — Herons Bonsai Walter Pall — Freelance Bonsai Artist Mauro Stemberger — Italian Bonsai Academy Kimura Masahiko — Kinbon Bonsai Garden Takeyama Takashi — Fujikawa Kouka-en Shinji Suzuki — Kaizen Bonsai Boon Manakitivipart — Bonsai Boon Jonas Dupuich — Bonsai Tonight Sergio Cuan — Bonsai Empire Colin Lewis — Freelance Bonsai Artist Kevin Willson — Bonsai Willson David Easterbrook — Freelance Bonsai Artist Graham Potter — Freelance Bonsai Artist Mauro Di Lorenzo — Bonsai Studio Italiano Eric Schrader — Bonsaify Andy Smith — Golden Arrow Bonsai Tony Tickle — Yardley Bonsai Jim Doyle — Bonsai Garden at Lake Merritt Kathy Shaner — Bonsai Garden at Lake Merritt Kathy and Jim Doyle — Bonsai Garden at Lake Merritt Bill Valavanis — International Bonsai Arboretum Frank Mihalic — Bonsai Artist Nick Lenz — Freelance Bonsai Artist Dan Robinson — Elandan Gardens David Benavente — Bonsai Kai Pedro Morales — Bonsai Sur Salvatore Liporace — UBI Bonsai Jan Schlauer — Carnivorous Plant Society Europe Barry Rice — Carnivorous Plant Society Stewart McPherson — Redfern Natural History Andreas Fleischmann — Botanische Staatssammlung München Charles Clarke — Monash University Fernando Rivadavia — Universidade Estadual de Campinas Robert Cantley — Borneo Exotics Alastair Robinson — Royal Botanic Gardens Victoria Andreas Wistuba — Wistuba Carnivorous Plants Lubomír Adamec — Institute of Botany, Czech Academy of Sciences Peter D’Amato — California Carnivores Barry Meyers-Rice — International Carnivorous Plant Society Richard Nunn — Freelance Carnivorous Plant Grower Ivan Snyder — Freelance Carnivorous Plant Grower Thomas Carow — Green Jaws Marcel van den Broek — Carnivorous Plant Nursery Christian Klein — Kleins Carnivorous Plants Marcel van den Berg — Dutch Carnivorous Plant Society Brian Barnes — California Carnivores Tamlin Magee — Meadowview Biological Research Station Aaron Ellison — Harvard University Paulo Gonella — Universidade de São Paulo Kai Müller — University of Würzburg François Mey — Société Botanique de France Nicolas Riddick — Freelance Carnivorous Plant Grower Adam Karremans — Lankester Botanical Garden Kamil Pásek — Best Carnivorous Plants Christian Dietz — Freelance Carnivorous Plant Researcher Adrian Slack — Carnivorous Plant Author Paul McMillan — Freelance Carnivorous Plant Researcher Tony Tickle — Bonsai Artist Koji Hiramatsu — Shunkaen Bonsai Museum Kunio Kobayashi — Shunkaen Bonsai Museum Masahiko Kimura — Kinbon Bonsai Garden Naoki Maeoka — Japanese Bonsai Artist Taiga Urushibata — Japanese Bonsai Artist Ryuji Suzuki — Japanese Bonsai Artist David De Groot — Bonsai De Groot Andrew Robson — Rakuyo Bonsai Leo Eshkenazi — Freelance Bonsai Artist Jason Chan — Eastern Leaf Kevin Wilson — Bonsai Willson Mark Fields — Evergreen Gardenworks Brent Walston — Evergreen Gardenworks Michael Tran — Muranaka Bonsai Nursery Roy Nagatoshi — Royal Bonsai Garden Mas Iida — Iida Bonsai Nursery Peter Tea — Freelance Bonsai Artist Tony Remington — Freelance Bonsai Artist Harry Harrington — Bonsai4Me Damon Collingsworth — California Carnivores Mike King — Carnivorous Plant Nursery Andreas Fleischmann — Munich Botanical Collection Stewart McPherson — Redfern Natural History Productions Matt Opel — International Carnivorous Plant Society Bob Ziemer — Meadowview Biological Research Station R

Hello there, and welcome back to Hydroponics Daily, your go-to podcast for everything soilless cultivation. I am your host, Dr. Russell Sharp, the founder of Eutrema Limited, a company that makes truly unique fertilizers, biostimulants, and biopesticides that you won't find anywhere else. The technology is completely unique. And today, the topic of the podcast is what I would do if I was faced with a virus in my crop. Specifically a crop where you want to protect the genetic material and you can't just throw the plants away often when we say when you've got a virus the first thing you should do is just destroy all plant material but what if you've got a strain a variety a cultivar that only you've got or is protected or is endangered or you need it for a breeding program or something like that and you need to get rid of the virus what are you going to do you can't give plants tamiflu that technology is not available you can't just wait for their immune system to fight the virus off because they don't have immune systems and so there's only really one option that i'm aware of and that's heat treatment so you when you're planting out cuttings tubers bulbs or seeds immersing them in hot water for a defined period can help with virus control. So we're talking about temperatures of 45 to 55 degrees Celsius. So you wouldn't keep plants, not many plants would live at that sort of temperature, they would soon die off, especially unless the humidity was really, really high. But the duration of which you give this treatment is only like 10 to 60 minutes. So in crops that's regularly, perennial crops, herbaceous perennial crops where they regularly suffer from viruses like sugar cane, sweet potato, banana, even grape vines and some ornamentals, you can do this and with success and control viruses. And you're best obviously doing it with smaller plants because smaller the plants, the more effective the treatment will be because of just the temperature profiles and things like that. Now obviously there's a big challenge there it could be phytotoxic it could just kill your plants from the heat but with a bit of experimentation you could find what is the sweet spot for your particular plant and in fact if I was going to do this if I had a plant that I needed to control the viruses I would do it until the plant breaks so I would get maybe 100 cuttings from a virus infected plant and I'd treat 10 at. What did I say the temperature was, 45 degrees Celsius for 10 minutes, and then all the way up to 10 that would be treated at 55 degrees Celsius for 60 minutes. No idea what that is in Fahrenheit, apologies for American listeners, but it's pretty warm, it's sort of like steam room temperature. So I would do a range and find out at what point did the plants die, and just go slightly below that, and really really stress it, because you don't want any virus particles in that new plant because it will be a source of infection and you will not get a chance to do this twice really so obviously seeds is the easiest but very rarely you won't go on to do that it's after that tubers something dormant a bulb they're going to be much more resistant much more tolerant of those high temperatures whereas a cutting is probably going to be the most sensitive but i would do it until it breaks if you're prepared to lose a few cuttings you could do it on unrooted cuttings and rooted cuttings i'd probably start with rooted cuttings see if you could get away with it because, severely stressing a cutting that's not rooted and then trying to get it to root you know you're not you you're in for a bad case there because you really struggle because it's all the cells are going to be weak and stressed from that heat treatment so i do it on rooted cuttings, newly rooted cuttings, not too much growing media around them. Okay, so that would be my. My suggestion, what are the success rates? If you're doing it on seeds, the sort of typical virus elimination you can ac

Dr. Russell Sharp explores the growing interest in perennial arable crops like Kernza, perennial rice and sorghum, explaining their environmental benefits, current commercial status, and the agronomic challenges they face. The episode also discusses breeding and gene-editing opportunities to improve yield and resilience, and considers how perennial grains might fit into hydroponic and niche high-value markets. https://eutrema.co.uk/ Maqsood Ali Wagan — Sindh Agriculture University Farhan Ali Wagan — Sindh Agriculture University Andrius Grigas — Lithuanian Research Centre for Agriculture and Forestry Dainius Steponavičius — Lithuanian Research Centre for Agriculture and Forestry Indrė Bručienė — Lithuanian Research Centre for Agriculture and Forestry Ričardas Krikštolaitis — Lithuanian Research Centre for Agriculture and Forestry Tomas Krilavičius — Lithuanian Research Centre for Agriculture and Forestry Aušra Steponavičienė — Lithuanian Research Centre for Agriculture and Forestry Dainius Savickas — Lithuanian Research Centre for Agriculture and Forestry Alejandro Perdomo López — Reaseheath College / University Centre Adrienn S. — Hungarian University of Agriculture and Life Sciences S.

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.

Dr. Russell Sharp discusses e-commerce strategies for hydroponic businesses, advising against competing in commodity leafy greens and recommending niche, high‑value preserved products like freeze‑dried herbs, pickles, and gourmet fermented goods. He outlines marketing channels (social ads, trade shows, brand storytelling), logistics considerations (cold chain vs preserved goods), alternatives like ornamentals and cut flowers, and cautions about high costs and platform pitfalls such as selling on Amazon. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ Greens For Good OnlyHydroponics Max Green Farms Gabbar Farms LEAFY (Leafy Scot) Oasis Hydroponics Sunway XFarms Vexotics Dizon Farms Delivers Biogrove Foodstories Kaze Living ElaGreens GetBlok FarmsGreens For GoodOnlyHydroponicsSunden FarmsUrban GreensRevol GreensVertical RootsVillage Farms InternationalOishiiSoli OrganicSquare Roots GrowVertical HarvestSmallholdFischer FarmsMarket 114Sustainable Farm by Custom CuisineLettuce GrowPlentyFarm Fresh to YouLive GreensLocal Greens FarmUrban Sprouts FarmFreshBox FarmsGreen Spirit FarmsEden Green FarmsGreen Sense FarmsLightHouse FarmsIron Ox FarmsBowery Urban GrowersGoodleaf FarmsFarm OneVertiCropFresh OriginsSundrop FarmsBrightFarmsHollandia Produce / Pete’s Living GreensMae FarmsCropOne HoldingsCity Farm CoPure Greens GrowersNational GreensEden Organic GreensHydroFarm Produce CoBlue River FarmsNuLeaf FarmsUrban Leaf GrowersFreshField FarmsTerra GreensHydroHarvestGreenLeaf Vertical Farms

Dr. Russell Sharp explains why bootstrapping is the best route for many hydroponic ventures, emphasizing unique products, testing market demand, and protecting cash flow. He warns against offering customer credit—suggesting pro forma payments and using strong order books to secure bank loans if scaling is needed—plus practical tips for long-term sustainability. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ Geoffrey Guy Brian Whittle Justin Gover Tom Whettem Adam Windish Paul Kenward Ben Langley Gabriel Newman Sam Ashton Jon Robson Maximillian White Mason Soiza Oliver Soar Scott Stephen Peter Zownir Graham Woodward Rupa Shah Dr Susan Jane Clenton Frances Crewdson Tom Gray Mike Morgan-Giles Nick Pateras Ricardo Geada Dr Sunil Arora Damien Bove Sam Cannon Hamish Clegg Matt Hughes James Leavesley Dr Shanna Marrinan Paul North Sonal Patel Tony Reeves Clare Holliday James Duckenfield Adam George Martin Dickie Richard Reed Christian Angermayer Maria Raga Irina Elena Haivas Sophia Bendz Fiona Pathiraja Michelle Tempest Leafy Tunnel Salica Measure 8 Venture Partners Casa Verde Capital Deepbridge Capital Kindred Capital

Dr. Russell Sharp breaks down how water is controlled in hydroponic systems: pressure‑regulated drippers set the flow rate, spikes only deliver the water, and solenoid valves control timing. He explains why pipe size matters little, how blockage and water hardness affect drippers, and why pH or RO water are common choices. This short episode also previews dosing and fertigation meters to be covered next, and offers practical tips for automating reliable irrigation. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/   Gotham Greens FresH2O Growers Thanet Earth The Green House Ely The Green House Sussex Village Farms International Vertical Harvest Farms Eden Green Technology Plenty AeroFarms GoodLeaf Farms Just Vertical ZipGrow Harvest Today Freight Farms Smallhold Elevate Farms Raiz Vertical Farms Eden Grow Systems Homer Farms Growponics Ltd.

Dr. Russell Sharp explores Egypt’s push into large-scale greenhouse and hydroponic production, driven in part by the military, and compares it to Morocco’s desalination-led expansion of fresh produce. The episode covers greenhouse construction, water supply challenges, berry and high-value crop ambitions, and how military involvement affects local agriculture and supply chains. It examines implications for food security, competition between countries, and the potential benefits and drawbacks of soilless cultivation when pursued at national scale. https://eutrema.co.uk/shop/ Tutankhamun Cleopatra Ramses II Nefertiti Imhotep Hatshepsut Omar Sharif Umm Kulthum Taha Hussein Naguib Mahfouz Gamal Abdel Nasser Anwar Sadat Mohamed Salah Dalida Amr Diab Ahmed Zewail Saad Zaghloul Boutros Boutros-Ghali Youssef Chahine Farouk Hosni

Dr. Russell Sharp explains why you should drastically reduce or stop fertilizing perennial crops during winter dormancy or cold storage. Plants take up little or no nutrients in cold conditions, and added nitrogen—especially ammonium—can convert to toxic nitrites that harm cellular respiration, photosynthesis and root health. He recommends dialling fertiliser back to near zero during dormancy, avoiding ammonium-based formulations in cold media, and resuming accurate dosing only when plants are actively growing or in heated environments. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ Rattan Lal – Ohio State University Asmeret Asefaw Berhe – U.S. Department of Energy, Office of Science Johan Six – ETH Zürich Diana H.
