• The International Space Station has a big Hydroponic Headache!

  Dr. Russell Sharp discusses recent research (published in npj Microgravity) showing that lettuce grown on the International Space Station contains significantly less calcium and magnesium and lower antioxidant and protective compounds than Earth-grown counterparts. These nutrient changes matter for astronauts who already face bone loss, radiation stress, and digestive changes in space. The episode explores possible causes (microgravity, humidity, lighting, fertiliser), solutions such as biofortification, bioengineering, and choosing flavonoid-rich or seed/legume crops like soybeans, and outlines future research directions for producing nutritionally adequate crops on long-duration space missions. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/   Tim Peake, Helen Sharman, Neil Armstrong, Sally Ride, Yuri Gagarin, John Glenn, Buzz Aldrin, Valentina Tereshkova, Blue Origin, SpaceX, Elon Mush, Jeff Bezos, Heinlein, Isaac Asimov, Arthur C.

• Growing Edamame Indoors: Japan's Hydroponic Breakthrough

  Dr. Russell Shaw explores recent Japanese research showing that edamame can be successfully grown hydroponically under LED lighting, yielding stable, high-quality crops independent of season. The indoor methods produced stronger plants, higher sugar and isoflavone levels, and suggest a way to grow nutrient-dense, protein-rich legumes in vertical farms—opening new opportunities beyond typical leafy greens. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/      Professor Toshio Sano from the Faculty of Bioscience and Applied Chemistry at Hosei University University of Tokyo  Wagamamas Nobu Matsuhisa Gordon Ramsay, Jamie Oliver, Heston Blumenthal, Mary Berry, Nigella Lawson, Tom Kerridge, and Rick Stein

• Hydrofarm: A Reality Check for the Hydroponics Industry

  Dr. Russell Sharp breaks down Hydrofarm’s latest results, falling sales, large write-downs and the company’s role as a barometer for the hydroponics and legal cannabis markets. The episode explores Hydrofarm’s brand portfolio, financial challenges, restructuring efforts and what the company’s struggles might mean for the wider hydroponic sector going forward. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/   nasdaq, new york stock exchange, london stock exchange

• Titanium & Plant Health: Miracle Micronutrient or Risky Gamble?

  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,

• Direct Air Capture for CO2 in Hydroponics

  Dr. Russell Sharp explores the promise of direct air capture (DAC) as a way to enrich CO2 for hydroponic and greenhouse crops without burning fossil fuels. He discusses a Japanese company (Seibu Gaiken) running successful trials that showed average yield increases of about 20%, and compares DAC to other CO2 sources like breweries and biogas. The episode highlights key caveats: DAC’s climate benefit depends on clean energy, units are currently large-scale, and they change heat management compared with gas burners. Dr. Sharp invites listener experience and feedback on whether vertical farms or large greenhouses will adopt this technology first. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/
