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.
