    Lightning in a Bottle: Plasma-Activated Water for Hydroponics

    This episode explores plasma-activated water (PAW): how ionized gas (like lightning) can be used to create reactive oxygen and nitrogen species that supply plant-available nitrogen and act as a natural sanitizer for hydroponic systems. We cover potential benefits (reduced synthetic nitrogen use, biofilm and pythium suppression, no toxic residue), practical approaches, current research and real-world trials, plus limitations such as dosing control, decay of reactive species, equipment costs and energy demands. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/

    Why Ladybirds Fail in Hydroponics: The Truth About Biocontrol

    This episode explains why ladybirds (ladybugs) are often poor biological control agents in hydroponic systems: adults tend to fly away, larvae may not eat aphids effectively or can die, they can clog filters, and invasive or disease issues can arise. Alternatives are discussed, including lacewings, predatory mites (which can be sustained with pollen), parasitoid wasps, entomopathogenic fungi, and other IPM strategies, plus considerations about cost, availability, and storage. https://eutrema.co.uk/shop/pesticides-organic/eutrema-insecticidal-soap-sodium-free/

    Hydroponic Mushrooms? Inside the World of Liquid Mycelium

    Dr. Russell Sharp investigates whether mushrooms can be grown without soil—covering liquid mycelium cultures, industrial mycelium bioreactors, and the limits of inert hydroponic media like rockwool. He explains that mycelium can be expanded in nutrient broths, but most mushrooms still need a solid organic substrate (straw, sawdust, or coffee grounds) to form fruiting bodies. The episode also discusses pests (fungus gnats), contamination risks, practical starter options (oyster mushrooms on pasteurized straw), and emerging applications for liquid-grown mycelium such as alternative proteins and flavourings. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/

    Wetting Agents in Hydroponics

    Dr. Russell Sharp breaks down the three main types of surfactants (anionic, cationic, non‑ionic), how they’re used to re-wet hydrophobic grow media, and their roles as adjuvants and insecticidal soaps. He warns against sodium-based products like sodium lauryl sulfate and recommends sodium-free alternatives, highlighting Eutrema’s clay drainer, yucca extract, and non-sodium insecticidal soap. https://eutrema.co.uk/shop/biostimulants/yucca-extract/ https://eutrema.co.uk/shop/pesticides-organic/eutrema-insecticidal-soap-sodium-free/ https://eutrema.co.uk/shop/soil-conditioners/clay-drainer/

    Inside Growy: A Robot-Run Vertical Farm Tour in Amsterdam

    Dr. Russell Sharp tours Growy’s Amsterdam vertical farm, exploring their unique fermented starch acetate growing media, automated gutter system with robots for seeding, irrigation and harvest, and energy‑efficient features like water‑cooled LEDs and heat recovery. The episode covers production figures (60 kg/m²/yr lettuce, 40 herbs, 35 microgreens), long shelf life, supply‑chain integration, crop challenges (spinach and basil), global expansion plans, and potential future mushroom projects. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/

    Hydroponics vs. Field Farming: The Real Reasons Supermarkets May Switch

    Dr. Russell Sharp contrasts outdoor soil-grown vegetables with hydroponic indoor production, focusing on labour differences, pest pressures, and contamination risks. He explains how the withdrawal of neonicotinoids and rising insect issues in Europe make hydroponics advantageous for pest control and cleaner produce, potentially influencing supermarket sourcing and consumer expectations. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/

    Roof Irises: The Perfect Ornamental for Hydroponics

    Dr. Russell Sharp discusses the potential of ornamental hydroponics and spotlights Iris tectorum (the roof iris) as an ideal species for indoor soilless cultivation due to its tolerance of low nutrients, stress, and inert media. The episode covers the plant’s historical roof cultivation in Asia and Europe, its bioactive compounds of pharmaceutical interest, and practical ideas like using reed thatch as a growing medium, urging growers to explore ornamentals as a niche in hydroponics. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/

    Cardboard, Hemp & Sawdust: Unconventional Microgreens Media Trial

    Dr. Russell Sharp tests unconventional, nutrient-free grow media for microgreens—hemp and microgreens matting, cardboard and coarse sawdust—comparing results for chia and onion in a hydroponic setup. The episode covers the trial design, potential issues (mould, decomposition, nutrient deficiencies, wood toxins) and invites listener feedback as the team observes outcomes. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/
