  • 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.

  • Don't Get Ripped Off: How to Choose Microbial Biostimulants

    Dr. Russell Sharp explains how to choose and use microbial biostimulants for hydroponics, focusing on production/expiry dates, manufacturer credibility, and the trade-offs between liquid and powder formulations.

    He recommends trusted suppliers (Legume Technology, Omex/Biomex, Symbiom, Koppert's Trianum P), suggests starting with Bacillus blends and Trichoderma, and advises using seaweed extracts, humic acids and mild fertilizers to feed, not kill, microbes.

  • Why Pumpkins Trap Forever Chemicals — and How Hydroponics Helps

    Dr. Russell Sharp explores research showing that squashes, pumpkins and other cucurbits can absorb persistent hydrophobic pollutants (PCBs, dioxin-like compounds, organochlorine pesticides and furans) because a specific plant protein binds these chemicals and transports them into the fruit.

    The episode covers the health and food-safety implications, the potential to breed low-accumulating varieties or use phytoremediation, and why growing these crops hydroponically is a safer alternative to avoid soil-borne, long-lasting pesticides.
