Eutrema Ltd: Grower - First Innovation

https://eutrema.co.uk/shop/fertiliser/ultimate-iron-fertiliser/ Dr. Russell Sharp explains why iron — a micronutrient, not a macronutrient — is essential for chlorophyll production and plant growth, and how its availability is strongly affected by pH. He covers signs of iron deficiency (chlorosis), differences in needs between arable crops, lawns, citrus and hydroponics, and why chelated iron often outperforms cheap iron sulphate for turf and sensitive crops. The episode also reviews practical treatments and products, application tips, the cosmetic vs physiological effects of iron on grass, and why alternatives like titanium rarely substitute effectively for iron.

https://eutrema.co.uk/shop/biostimulants/salicylic-acid-solution-eutrema-exclusive/ In this episode Dr. Russell Sharp explains what salicylic acid is, how it works as a plant hormone and elicitor, and why it triggers systemic acquired resistance to help control pests, pathogens and some environmental stresses. He discusses different forms (including methyl salicylate), practical benefits such as improved disease resistance, enhanced flavor and secondary metabolites, seed germination support and cut‑flower preservation, plus real‑world application examples and recommended rates. The episode also covers formulation and tank‑mix compatibility (including Eutrema’s concentrated liquid product), safety precautions, storage guidance and when to use salicylic acid as part of an integrated crop management strategy.

https://eutrema.co.uk/shop/organic-fertilisers/triacontanol-boost-biostimulant/ Dr. Russell Sharp explores triacontanol, a natural fatty-acid biostimulant extracted from beeswax or plant cuticles that can drive faster photosynthesis, vigorous vegetative growth, and heavier yields despite an unclear mode of action. The episode covers Eutrema’s organic, solvent-free 0.2% tricontanol concentrate, recommended application rates for hydroponics, turf and field crops, compatibility and cleaning considerations for sterile systems, and tips on testing with small trial dosages.

https://eutrema.co.uk/shop/organic-fertilisers/yucca-extract/ Dr. Russell Sharp explains what true horticultural yucca extract is (from desert yucca, not cassava) and why it’s used: saponins act as natural wetting agents to improve water uptake, help flush salts and allelopathic chemicals, serve as an organic insecticidal soap for soft-bodied pests, and can provide biostimulant effects in fertilisers and livestock feed. He also covers product quality and use: how pure yucca looks and behaves, common adulteration with synthetic surfactants or dilution, what to check on labels and safety data sheets, and practical tips for using yucca in soil, pots, and hydroponics.

Magnesium+ = https://eutrema.co.uk/shop/soil-conditioners/magnesium/ Ultimate Cal-Mag = https://eutrema.co.uk/shop/soil-conditioners/ultimate-cal-mag/ Dr. Russell Sharp explains magnesium’s central role in plants as the atom in chlorophyll, the typical signs of deficiency (interveinal chlorosis on older leaves), and why visible symptoms can be hard to spot in grasses and late to appear. The episode covers common causes like nutrient antagonism from excess calcium or potassium, diagnostic tips, and practical remedies including CalMag for hydroponics, magnesium-plus foliar sprays for lawns, and Epsom salts for fruit crops, plus guidance on prevention and product choices.

https://eutrema.co.uk/shop/equipment/hand-lens-uv-led-illuminated/ Dr. Russell Sharp explains why a hand lens is essential for pest identification and monitoring, how to use one, and the main reasons to inspect plants closely rather than guessing. He covers tiny pests like spider mites and thrips, distinguishing beneficial insects, confirming kills, and locating eggs. The episode also reviews disease signs, trichome inspection for essential oil crops, root and rhizosphere checks, and advantages of LED and UV illumination. Regular close inspection with a hand lens can catch problems early and help avoid unnecessary pesticide use.

In this episode Dr. Russell Sharp explains insecticidal soaps—how they work by physically breaking down insect waxes and spiracles, acting as contact killers without systemic residues. He covers practical use: effective mainly on soft-bodied pests and powdery mildew, the need for repeat sprays (every 5–7 days) during infestations, and precautions to avoid phytotoxicity and high temperatures. Tips for choosing products focus on plant-safe, sodium-free formulas (potassium/ammonium alternatives), tank-mix compatibility, and organic options like Yucca Extract.

Dr. Russell Sharp reviews the Maxi Bright Maxi LED Pro TS 40W horseshoe under-canopy light, calling it the best product he has seen this year and explaining how individual under-pot lighting can boost photosynthesis, improve transpiration and reduce fungal risks. He proposes a potential upgrade—combining the horseshoe LED with a horseshoe dripper to warm roots and cool LEDs—then explains why cost and safety (mixing water and electrics) make that unlikely. Russell contrasts this standout product with a recently over-engineered launch, invites listener feedback, and points listeners to Hydro Bros' social channels for demos and to utreema.co.uk for more information. https://eutrema.co.uk/

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. https://eutrema.co.uk/

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. https://eutrema.co.uk/
