• Ferns in Hydroponics: From Victorian Mania to Modern Houseplant Gold

  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. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/   Joe Swift Home Grown Marf’s Kitchen Garden Nettles & Petals Tales from the potting shed Adam kirtland NPK Hydroponics NPK Media Kyle Kushman Advanced Nutrients Big Mike Straumietis

• Minecraft and Vertical Farms: Harvest London's Canary Wharf Operation

  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. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/   Harvest London Canary Wharf Canada Square Pear Tree Kitchen Pizza Pilgrims Chelsea Physic Garden

• Secrets of Stomata: How Plants Balance Water and CO2

  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. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/   Chelsea Flower Show Monstera Philodendron Autoflowers Photoperiod Autoflower Alan Titchmarsh Monty Don Rachel De Thane James Wong Gardeners World Horticulture Week Gardeners Question Time RHS Royal Horticultural Society Garden Organic Joe Swift Soil Association  Organic Farmers & Growers Hampton Court Flower Show
