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.
