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.
