The Hydrogen Peroxide Clash Rocking European Hydroponics

Dr. Russell Sharp discusses the struggle of the UK and European hydroponic sector, focusing on recent enforcement in the Netherlands over continuous in-line dosing of hydrogen peroxide. He explains why regulators flagged the practice, the science behind peroxide breakdown, and his frustration with overly rigid enforcement.
Russell also offers practical advice: avoid continuous peroxide dosing to protect roots and yields, keep systems clean, and use peroxide sparingly. He reflects on the wider impact of regulation on innovation and shares how his company adapts to EU rules.

E‑Commerce Strategies for Hydroponic Growers

Dr. Russell Sharp discusses e-commerce strategies for hydroponic businesses, advising against competing in commodity leafy greens and recommending niche, high‑value preserved products like freeze‑dried herbs, pickles, and gourmet fermented goods.
He outlines marketing channels (social ads, trade shows, brand storytelling), logistics considerations (cold chain vs preserved goods), alternatives like ornamentals and cut flowers, and cautions about high costs and platform pitfalls such as selling on Amazon.

Bootstrap to Success: Ditch credit for your customers

Dr. Russell Sharp explains why bootstrapping is the best route for many hydroponic ventures, emphasizing unique products, testing market demand, and protecting cash flow.
He warns against offering customer credit—suggesting pro forma payments and using strong order books to secure bank loans if scaling is needed—plus practical tips for long-term sustainability.

Solenoids & Drippers: Master Hydroponic Water Flow

Dr. Russell Sharp breaks down how water is controlled in hydroponic systems: pressure‑regulated drippers set the flow rate, spikes only deliver the water, and solenoid valves control timing. He explains why pipe size matters little, how blockage and water hardness affect drippers, and why pH or RO water are common choices.
This short episode also previews dosing and fertigation meters to be covered next, and offers practical tips for automating reliable irrigation.

Egypt’s Greenhouse Push: Army-Driven Hydroponics vs Morocco’s Desalination Boom

Dr. Russell Sharp explores Egypt’s push into large-scale greenhouse and hydroponic production, driven in part by the military, and compares it to Morocco’s desalination-led expansion of fresh produce. The episode covers greenhouse construction, water supply challenges, berry and high-value crop ambitions, and how military involvement affects local agriculture and supply chains.
It examines implications for food security, competition between countries, and the potential benefits and drawbacks of soilless cultivation when pursued at national scale.

Don't Feed Dormant Plants: The Hidden Nitrite Danger

Dr. Russell Sharp explains why you should drastically reduce or stop fertilizing perennial crops during winter dormancy or cold storage. Plants take up little or no nutrients in cold conditions, and added nitrogen—especially ammonium—can convert to toxic nitrites that harm cellular respiration, photosynthesis and root health.
He recommends dialling fertiliser back to near zero during dormancy, avoiding ammonium-based formulations in cold media, and resuming accurate dosing only when plants are actively growing or in heated environments.

Lease to Grow: The Rise of Rental Hydroponic Systems

In this episode Dr. Russell Sharp explores leasing and rental business models for hydroponic systems—ranging from small kitchen towers to commercial vertical farms—covering potential revenue streams, financing advantages, turnkey options for growers, and the practical risks involved.
He highlights examples from the industry, discusses who benefits from rentals, and invites listeners to share their experiences or case studies.

Rats in the NFT: Rodents, Risks and Hydroponic Safety

Dr. Russell Sharp of Utrema discusses a striking Facebook post—an AI image of rat droppings on an NFT lettuce system—and asks whether rodents are a real threat in hydroponics.
The episode covers the main risks rodents pose: disease transmission (salmonella, leptospirosis, hantavirus), contamination of recirculating fertigation solutions, crop damage, and quality/safety losses.
Practical control advice is offered using an integrated pest management approach: seal entry points, install fine mesh on vents, reduce outdoor hiding spots, use traps (preferred over poisons), monitor and keep pest logs, and consider professional tamper-resistant services for larger operations.
