Dr. Russell Sharp explains how Dosatrons (water-powered dosing pumps) mix concentrated fertilizer like Gold Leaf/Liquid Gold into fertigation systems, describing the piston-driven mechanism, proportional injection, and why it maintains a constant concentration despite flow changes.

The episode covers practical setup tips for off-grid hydroponics — solenoids, drippers, solar pumps, and how a Dosatron enables accurate, electricity-free dosing, along with limitations (not for powders, pressure loss, very viscous or abrasive chemicals) and a brief mention of Venturi injectors.

Dr. Russell Sharp of Hydroponics Daily breaks down the truth behind "cut-and-come-again" vegetables and viral social media hacks, explaining which crops genuinely regrow and which claims are misleading.

Learn which leafy herbs and greens can be harvested multiple times, why most bulky vegetables won’t produce a marketable second crop, and when starting fresh is a better option for consistent yields.

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.

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.

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.

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.
