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 Minnesota Andrew Taylor — University of Nottingham Russell Keast — Deakin University Charles Spence — University of Oxford Harrison Schmitt — Virginia Tech Morten Møller — University of Copenhagen John Hayes — Penn State University Qian Janice Wang — Aarhus University Marcia Pelchat — Monell Chemical Senses Center Barry Smith — University of London Linda Bartoshuk — University of Florida Paul Breslin — Monell Chemical Senses Center Danielle Reed — Monell Chemical Senses Center Barry Green — Monell Chemical Senses Center Thomas Hummel — Technical University of Dresden Alan Hirsch — Smell & Taste Treatment and Research Foundation Susan Schiffman — Duke University Molly Birnbaum — Freelance Food Writer Harold McGee — Freelance Food Writer Kantha Shelke — Corvus Blue Tim Hanni — Master of Wine Institute Geoffrey Talavera — Freelance Flavor Consultant Peter Schieberle — Technical University of Munich Thomas Hofmann — Technical University of Munich Corinna Dawid — Technical University of Munich Veronika Somoza — University of Vienna Morten Andersen — University of Copenhagen Christophe Lavalle — AgroParisTech Stéphane Guichard — INRAE Thierry Thomas-Danguin — INRAE Erich Leitner — Graz University of Technology Hans-Georg Schmarr — University of Hohenheim Elke Pawelzik — University of Göttingen Michael Witting — Helmholtz Zentrum München Ralf Zimmermann — University of Rostock Francesco Capozzi — University of Bologna Giovanni Capuano — University of Naples Federico II Maurizio Servili — University of Perugia Rosa Lo Scalzo — CREA Italy Paolo Masella — University of Parma Fidel Toldrá — Instituto de Agroquímica y Tecnología de Alimentos María Dolores del Castillo — Spanish National Research Council Dolores Coreta-Gomis — University of Valencia Juan Fernández-García — University of Granada Ana Bayarri — University of Valencia Marta Corredig — Aarhus University Marina Heinonen — University of Helsinki Anu Hopia — University of Turku Kees de Graaf — Wageningen University & Research Gerry Barker — University of Leeds Jean-Marie Lehn — Max Planck Institute for Polymer Research Wilfried Meyerhof — German Institute of Human Nutrition Maik Behrens — German Institute of Human Nutrition John Prescott — University of Otago Anna M.

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 Ron Determann — Meadowview Biological Research Station Tom Luecking — Freelance Carnivorous Plant Grower Richard Myers — Carnivorous Plant Society UK Adrian Yeo — Singapore Botanic Gardens Ch’ng Khoon Meng — Singapore Botanic Gardens Paul Harwood — Carnivorous Plant Society UK Jan Schlauer — Botanical Researcher Barry Rice — ICPS Peter D’Amato — California Carnivores Ryan McEnaney — Chicago Botanic Garden Kevin Wilson — Bonsai Willson Jonas Dupuich — Bonsai Tonight Bjorn Bjorholm — Eisei-en Bonsai Stewart McPherson — Redfern Natural History

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 achieve is 60 to 90%. Whole plant cure rate, typically around 50%. So you may need to screen the plants and quarantine and destroy any plants that are not completely successful. Micropropagation as well. There's often a technique that's used in micropropagation because you can, these plants are so much smaller than a normal cutting than a normal plant that you can quickly get them to the temperature and then back down again quickly whereas a a large corm or bulb or tuber you could think you can get in the center of that tuber to 50 degrees celsius means much longer and the outside temperature will have to be a lot warmer so so yeah that's probably going to be lower success rate there what else can we say this is sort of the term is thermotherapy by the way so what else can we say about it you can do it on whole plants large plants but you would probably need a grow room dedicated to it with a sort of a temperature of high 30s probably early 40s for two to six weeks that's a lot of heat if you're not in a tropical or arid area but you've got fruit trees large fruit trees ornamentals that are just infected then it might be worth it for targeting systemic viruses and preserving the whole plant structure rather than going back down to cuttings and starting it all over again. The heat stress will reduce the vigour and survival of the plants. You'll probably get some scorching on the leaves and things like that. So if it's an ornamental plant, you might reduce that. The success rates for whole plant thermotherapy are lower. So 30 to 70% virus elimination. And just because the temperatures are lower, so the virus isn't exposed to such a high temperature. And maybe this is why, you know, when you get a virus, like a cold or a flu, your body heats up because viruses don't like high temperatures. But, you know, tropical plants still get viruses. So I'd imagine this is harder to do on tropical plants and easier to do on temperate plants, because tropical plants are going to be exposed to these high temperatures anyway, and the viruses will be adapted to them. It will depend on the virus and its genetics, because even though they're not alive, they have genetics, they have genes, whether that's RNA or DNA. So the virus biology will have an effect and the host tolerance the ability to withstand those high temperatures will be key and the precise treatment i would probably do a water bath would probably be the easiest way to do it with cuttings now a water bath you can set to a set temperature and and dunk them in what's that thing they use in kitchens is it a bain marie when they when they're cooking steaks very precise temperatures you could potentially use one of those as well and or Or if you fail in that, a pot on a stove or something in an oven, some water in an oven that could get the plants to 50 degrees Celsius uniformly. So you don't want to put them in dry heat in an oven because they're exposed to all sorts of temperatures there. Definitely don't just put them in an oven. Definitely use a water bath for cuttings and things like that. So that would be my top tip. Just sort of Google there. You can pick up a Bain-Marie for like 100, 140 pounds. So that's not a lot considering the value if you're going to go to these lengths then the value of these plants must be considerable if you're going to spend the time and effort to try and eliminate viruses from them and potentially you know with virus testing getting better and better and more what's the word i'm looking for accessible you could potentially have a nice little hydroponic. Business selling certified virus-free heat treated cuttings that could be one of the things if you if in your industry cuttings there's a there's a business is selling cuttings and you're looking for a unique selling point then potentially you could say our product our cuttings are all heat treated and checked and checked for viruses before they leave the nursery and that could be a really good small little venture little bootstrapped hydroponic company to get you going up and running, selling, cuttings, and propagation material. Anyway, that's been Hydroponics Daily for today. If you found it interesting, please do give us an Apple podcast review because it does help spread the word of hydroponics with the wider horticultural gardening community and scientific community. If you're not an Apple, just make sure you follow the podcast so you don't miss an episode. We've got about 14 episodes left of 2025. I've done an episode every day, at the very least check out www.Eutrema.co.uk for all your amazing. Fertilizers, biostimulants and biopesticides. None of our products control viruses because you can't control a virus. You have to either destroy your plants or heat treat them. You can use insecticides to prevent the spread of aphids, which transfer the viruses. We don't sell insecticides, we sell an insecticide or soap and that's about it. So yeah, that's been Hydroponics Daily for today. Thank you very much for listening and I'll see you again tomorrow. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ Roger Hull — John Innes Centre David Baulcombe — University of Cambridge James Carrington — Donald Danforth Plant Science Center Andrew O.

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.

Dr. Russell Sharp shares a practical hack to dramatically reduce pesticide and biocontrol costs by culturing predatory mites on bran or pollen. This method lets growers seed a small container with purchased predatory mites, grow their prey mites on a feedstock, and maintain a self-sustaining predatory population to protect crops. Key steps and precautions: buy untreated bran from an animal feed store, seed a small sealed container with purchased mites, keep warm with slight moisture, rotate harvests (use ~80% for release, keep ~20% to restart), and avoid storing bran near human food or large open volumes to prevent infestations. Works for leaf and soil predators and can be scaled from houseplants to large farms. https://eutrema.co.uk/shop/pesticides-organic/lime-sulphur/ Roland De Jonghe – Biobest Group Silvia Todorova – Anatis Bioprotection Claude Robert – Anatis Bioprotection Don Elliott – Applied Bio-nomics Brian Spencer – Applied Bio-nomics José Vanzeler de Melo – Agronologica Patrick Charlot – Bioline AgroSciences David Ben-Zvi – BioBee Sde Eliyahu Moshe Sagiv – BioBee Sde Eliyahu Arnold Yasin – BioBee Sde Eliyahu Octávio Peres Neto – Biotrop Fábio Passos – Biotrop Fernando Reis – Biotrop Keith Jones – Certis Biologicals Robert G.

Dr. Russell Sharp explores the role of titanium in plant health; what it is, how it’s used (chelated salts, titanium dioxide nanoparticles, foliar and root applications), and why it’s attracting interest in the biostimulant world. Although titanium is not an essential nutrient, low doses have sometimes boosted chlorophyll, photosynthesis, nutrient uptake and stress tolerance; effects depend strongly on species, particle form, application method and the plant’s iron and nutrient status. However, titanium shows a hormetic response: low doses can help but higher doses cause chlorosis, necrosis and growth suppression, with no clear safe thresholds—so the episode warns against using titanium fertilizers and recommends correcting core nutrient imbalances first. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ Robocop, suncream, sunscreen, hip replacements, SR-71 Blackbird, Lockheed A-12 archangel, William Gregor, mannacan,

In this episode Dr. Sharp explores the unusual topic of growing weeds — specifically black grass — using hydroponics. Key Points: Why Grow Black Grass? Black grass is the #1 arable weed in the UK, especially harmful to cereal crops like wheat and barley. It’s resistant to herbicides and there are no GM crops in the UK to help control it. Public is unaware of its impact because it doesn't affect home gardens — unlike more well-known weeds like Japanese knotweed. Eutrema’s Approach: Dr. Sharp’s company, Eutrema , is developing biological control methods using naturally occurring mildew and rust pathogens. These fungi stunt black grass growth (rather than kill it), allowing cereal crops to outcompete it. Their pathogens are highly specific (forma specialis) and pose no risk to other crops. Why Hydroponics? Black grass is difficult to grow in greenhouses and standard compost due to pests and diseases like “take-all.” Hydroponics allows for clean, controlled growth, eliminating many variables. They use NFT systems (nutrient film technique) for better consistency and plant health. Challenges in Growing Black Grass: It’s tough to germinate and cultivate due to its seed structure and sensitivity. Silicon is crucial in their nutrient mix because grasses like black grass accumulate high levels of silicon. Interesting Experiments: Testing how UV light affects spore viability. Developing plant-friendly “sunscreen” formulations to protect beneficial fungi from UV damage. Beyond Black Grass – Other Weeds for Hydroponics: Dr. Sharp muses on potential uses for other “weeds”: Fat hen (once a Roman crop), dandelions (used for medicine and drink), shepherd’s purse (edible in Asia). Mentions nettles (textile potential), Japanese knotweed (biostimulant uses), and even moss (teased for the next episode). 🔬 Takeaway: This episode flips the script — instead of eradicating weeds, it explores cultivating them as part of solving major agricultural problems. It’s a smart fusion of hydroponics, pathology, and sustainable innovation, with potential to scale. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/
