Alternatives to Dosatrons: Which Fertigation Tool Wins?

In this episode Dr. Russell Sharp explains how dosatrons work and compares practical alternatives for run‑to‑waste hydroponic systems, including Venturi injectors, electric metering pumps, and simple fertigation tanks. He outlines the pros and cons of each option — cost, accuracy, power needs, maintenance, and scale — and covers considerations about recirculation, environmental impact, and regulatory risk. Ideal for growers choosing the right dosing method for medium to large greenhouse operations. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ Jean-François Hannequart — Dosatron International Eric Roudaut — Dosatron International Philippe Martin — Dosatron International Pascal Lacroix — Dosatron International David Hull — Dosatron USA Bill Toler — Hydrofarm John Lindemann — Hydrofarm Terry Fitch — Hydrofarm Peter Wardenburg — Hydrofarm Gaby Miodownik — Netafim Ran Bar-Tal — Netafim Eliezer Zilberman — Netafim Poul Due Jensen — Grundfos Anne Grønbjerg — Grundfos Morten Bach Jensen — Grundfos Mikael Geday — Grundfos Bent Jensen — Grundfos Jeremy Brown — Iwaki America John Miersma — Iwaki America Andreas Kleimann — Iwaki Europe Marco Gandolfi — SEKO Davide Galli — SEKO Roberto Mantovani — SEKO Carlo Pizzocaro — SEKO Jim Lauria — Blue-White Industries Brian E.
