Dr. Russell Sharp explains why plants like rhododendrons and other ornamentals sometimes flower in autumn — a phenomenon called precocious flowering caused by stress or unseasonal warmth. He outlines how this early bloom reduces spring displays and can ruin fruit crops.
The episode discusses implications for hydroponic and indoor growers (especially strawberries and perennial crops), the need for cold treatment in some species, and practical considerations for vertical farming and controlled environments.

Dr. Russell Sharp explores whether ferns are a viable hydroponic crop, covering their limited edibility, high value as houseplants, and conservation concerns from historic "fern mania."
The episode explains fern biology and propagation—spores, gametophytes, divisions and micropropagation—plus humidity, foliar uptake, and practical hydroponic considerations for successful cultivation.

Dr. Russell Sharp explores Harvest London’s open, glass-walled hydroponic farm at Canary Wharf—an accessible vertical farm supplying leafy greens and microgreens to local restaurants and food stalls. The multi-tier, pesticide-free system is visible to the public, making hydroponics educational and tangible for visitors.
The episode highlights how public display boosts trust and perceived value, the site’s strict biosecurity and clean operations, and why integrating visible farms into food halls can be more effective than hidden rooftop setups.

Russell introduces his hydroponics-themed Top Trumps card pack covering 32 pests, diseases and physiological issues, scored by damage, commonness, difficulty to treat and "bounce-back" ability. He outlines plans to print the cards, asks for feedback on entries, and notes podcast milestones and resources at eutrema.co.uk.

Dr. Russell Sharp explains how stomata—tiny pores on leaves controlled by guard cells—regulate gas exchange and water loss, why their opening matters for photosynthesis, and how stomatal conductance is measured and used to assess plant stress.
He also shares a simple, practical method for growers: the clear nail varnish peel technique to capture leaf impressions and view stomata under a microscope, plus notes on measuring limitations and applications for hydroponic systems.

Dr. Russell Sharp explains hardwood cuttings for deciduous woody perennials, why they’re useful in autumn and winter, and how they’re easier and cheaper than softwood cuttings. He covers methods—using sand, perlite or a heated propagator, basal heat, rooting hormone, tips for hydroponic transfers, species that root well (willow, mulberry, hydrangea, dogwood), and how to avoid problems like pythium. Practical advice for propagating and transitioning cuttings into hydroponic systems.

Dr. Russell Sharp reviews Lettuce Grow, a celebrity-backed company (founded in 2019) that sells stylish, kitchen-scale hydroponic stands and kits like the Farmstand. He covers design, multi-layer systems, recirculating pumps, and accessories aimed at home growers.
The episode discusses seedlings, fertilizers (A/B and one-part options), expected yields, pricing and usability for beginners, and why Lettuce Grow appeals as a direct-to-consumer, design-focused hydroponics brand.

Dr. Russell Sharp explains how EC meters work, what they’re useful for and their key limitations — including temperature sensitivity, inability to distinguish ion types, and poor detection of many organic inputs like Liquid Gold (Gold Leaf).
Practical tips: always measure EC and pH in your actual water after adding the manufacturer’s recommended dose, flush runoff to prevent salt build‑up, and only use generic EC charts for standard mineral feeds — not for novel or organic fertilisers.

In this episode Dr. Russell Sharp discusses an Israeli study showing that diindolemethane (DIM), a compound formed when we digest cruciferous vegetables like broccoli and cabbage, can inhibit Streptococcus mutans growth and disrupt dental plaque.
The episode covers how DIM could be used in future oral-care products or encouraged through diet, touches on brassica benefits for soil and hydroponics, and notes related trade and supply updates affecting produce transport.
