Hand Lens - why every grower needs one

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/

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. https://eutrema.co.uk/plant-health-periodic-table-poster/

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.
