• Predicting Cannabis Potency with Your Smartphone: Hyperspectral Breakthrough

  Dr. Russell Sharp explores recent research showing that hyperspectral leaf scans combined with machine learning can predict cannabinoid concentrations in legal cannabis before harvest, and outlines a new technique that could let standard smartphone cameras act like hyperspectral sensors using a reference card and software. The episode covers practical applications for growers and breeders; from pre‑selling crops and ensuring hemp THC compliance to rapidly screening seedlings, and considers how these tools could be brought together in a future smartphone app. https://eutrema.co.uk/shop/biostimulants/slugger/   Compolytics fan leaf hyperspectral reflectance (FLHR) University of Adelaide's Dr Aaron Phillips Purdue University researcher Young Kim Semin Kwon of the Weldon School of Biomedical Engineering  James Hutton Institute Dundee

• How Weight-Loss Drugs Could Reshape Global Crop Demand

  Dr. Russell Sharp explores how widespread use of GLP‑1 weight‑loss drugs (soon available orally) could reduce overall calorie intake and shift demand across crop types. He outlines the likely big losers (corn/maize, soybeans, sugar, palm oil) and relative winners (pulses, fibre‑rich fruits and vegetables, premium proteins), as well as crops likely to remain stable (rice, wheat, tubers) and non‑food crops largely unaffected. The episode discusses implications for hydroponics and horticulture, potential changes in the food and leisure industries, and cautions about drug side effects and broader societal impacts. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ Liraglutide Victoza,  Saxenda  Semaglutide, Ozempic, Wegovy Tirzepatide Mounjaro  Robbie Williams, Greggs the baker, McDonalds, KFC, Wendy's, Chick-fil-a, chipotle, beyond meat, impossible foods, subway, waitrose, tesco, sainsbury's, asda, aldi, lidl, hyrox, crossfit, turf games, park run, personal trainers, david lloyd gyms, jd sports, jd gyms, virgin active, vitality insurance,

• Spain's Radical Plan: 20–30 Day Crop Shutdown to Kill Thrips

  Dr. Russell Sharp explores a controversial strategy where entire growing regions pause production for 20–30 days to break pest life cycles — using crop removal, soil solarization and biological controls. He compares past field-crop proposals to recent plans in Almería to tackle thrips and discusses the economic pain, possible aid, and whether coordinated shutdowns could work for other crops. The episode weighs practical challenges, examples from rapeseed and protected crops, and asks listeners to consider if collective action can realistically eliminate stubborn pests or diseases. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/   Andrés Iniesta, Xavi, Sergio Ramos, Carles Puyol, Iker Casillas, lamine yamal,

• Vanilla Cultivation - Hand-Pollinated Gold

  Dr. Russell Sharp dives into the unique world of vanilla: an orchid vine that requires delicate, manual pollination outside its native range, long development times, and careful curing. Learn why vanilla farming is labor-intensive, how hydroponic tower systems are being used, and what breeders are doing to improve resilience and pollination. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/   Ice cream Custard Madagascar Indonesia Nepal India

• Hydroponics on the Alkaline Edge: Crops That Cope with High pH

  Dr. Russell Sharp explores plants and crops that tolerate very alkaline soils and how that knowledge applies to hydroponic systems. The episode covers common tolerant crops (barley, sugar beet, cotton, sorghum, alfalfa, buffalo/Bermuda grass) and highly tolerant species like Atriplex as a possible spinach substitute in high‑pH water. Practical tips include expected pH ranges, when alkalinity and salinity overlap, and suggestions for experimenting with gardener's orache (Atriplex) in hydroponics. Contact the host for advice on adapting fertigation and crop choices to alkaline conditions. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/
