  • Eutrema Ltd: Grower - First Innovation

    Dr. Russell Sharp, founder of Eutrema Limited, explains the company's grower-first approach, serendipitous innovation, and the development of truly unique plant science products.

    The episode covers Eutrema’s focus on sustainable, biorational solutions -like fully soluble liquid gypsum and concentrated salicylic acid, transparent formulations, and direct access to expert support.

    Listeners also learn about free resources, podcasts, and how buying from Eutrema supports British innovation.

  • Fertiliser Time Bomb: gas, geopolitics & carbon taxes threatening 2027 Prices

    Dr. Russell Sharp ranks and explains the major threats to fertilizer and pesticide prices in the UK looking toward 2027, covering energy costs, geopolitical risks, supply bottlenecks, and regulatory changes.

    The episode highlights rising natural gas and oil prices, sulphur and phosphate shortages, Russia and Middle East tensions, the UK carbon border adjustment mechanism, potential sanctions on suppliers, and proposed harmonised regulations that could harm smaller biostimulant and hydroponic businesses.

    Listeners will learn how these factors could drive up input costs, reduce product choice, squeeze farm margins, and feed into higher food and turf-care prices — plus what to watch for in the coming months.

  • The Periodic Table of Plant Health — Decode Your Crop's Nutrient Needs

    Dr. Russell Sharp walks through the "Periodic Table of Plant Health," explaining macronutrients, micronutrients, non-mineral and non-essential elements, and common deficiency symptoms for hydroponic crops.

    He also describes practical solutions, timing advice, free A4/A1 posters and sample swag available from Eutrema to help growers diagnose and manage plant nutrition more effectively.

  • Inside Our New Patented Root Stimulant: A Phosphite Alternative

    Dr. Russell Sharp discusses recent weather impacts on crops and lawns, a Black Friday humic acid offer (use code HUMIC15), and updates from Utrema on product compatibility tools and trade show plans.

    The main focus is a new food‑grade root stimulant being developed to replace potassium phosphite: how it works, plans to patent it, and the testing program across at least nine plant species including greenhouse split‑pot trials and future field trials.

    Listeners are invited to request small samples, follow progress on compatibility and tank‑mix data, and watch for upcoming trial results and product launch details.

  • Are your microbes dead? Free new service from Eutrema

    Dr. Russell Sharp explains why Eutrema no longer sells microbial products — from short shelf life and supply-chain dilution to competition with contaminated products — and why regulation alone won’t fix the industry.

    He also announces a free testing service at Eutrema HQ in Lutterworth to verify whether microbial products contain the live, correct organisms claimed, and reminds listeners that Eutrema manufactures its own unique fertilizers and biostimulants.

  • Insider Advice for Hydroponic Product Startups

    Dr. Russell Sharp of Eutrema shares practical advice for anyone launching a hydroponic product, covering market realities, product differentiation, and regulatory pitfalls.

    Key takeaways: the UK market is quiet, focus on unique solutions, be prepared to say no, manage marketing spend, understand regulations, protect your business by bootstrapping, and treat grow shop owners as vital partners.

  • UK Fertiliser Rules Could Wipe Out Small Hydro Brands — What You Need to Know

    Hello and welcome back to Hydroponics Daily. Dr. Russell Sharp breaks down the new UK fertiliser and biostimulant consultation that could force costly registrations, third‑party efficacy testing and ingredient disclosure, risking many small brands and shrinking product ranges.

    He explains the likely impact on hydroponics, lawn care and agriculture, why larger multinationals may benefit, how Utrema expects to cope, and urges listeners to respond to the consultation.

  • Taming Bitterness: How Hydroponics Could Create Milder Veggies

    Dr. Russell Sharp explores how breeders, genetic tools (including CRISPR) and environmental controls in hydroponics can reduce strong or bitter flavours in vegetables.

    He highlights examples—low‑sulphur Brussels sprouts and onions, milder marrows/zucchini, soap‑free coriander, low‑oxalate spinach, less‑phenolic eggplant and sweeter lettuce—and points to hydroponic fertilizer strategies and business opportunities for growers and breeders.

  • The Top 10 Most Poisonous Plants You Might Grow (but hey, "they're natural")

    Dr. Russell Sharp closes out Hydroponics Daily’s 2025 run with a compact guide to the most toxic plants. He explains why “natural” or “plant‑derived” doesn’t mean safe and shares examples of species that can cause severe harm.

    The episode lists the top poisonous plants to watch for, such as hemlock, giant hogweed, deadly nightshade, Brugmansia, monk’s hood, yew, oleander, castor bean, water hemlock and foxglove, plus practical safety warnings for growers and gardeners.

  • Biofortify Your Greens: Iodine, Selenium & Hydroponic Nutrition

    Host Dr. Russell Sharp of Hydroponics Daily explains how hydroponic fertigation and his product Gold Leaf (Liquid Gold in the UK) can be used to biofortify edible crops with nutrients like iodine, selenium, iron, zinc and silicon.

    The episode covers practical benefits, higher micronutrient content, potential shelf-life and quality improvements, and serious cautions, especially selenium toxicity, stressing professional handling and precise dosing.

    Listeners learn why hydroponics makes targeted nutrient enrichment easier than soil, which crops have been shown to respond (lettuce, basil), and how biofortification might impact human nutrition and future dietary needs.
