Show Notes
Dr. Russell Sharp explains how EC meters work, what they’re useful for and their key limitations — including temperature sensitivity, inability to distinguish ion types, and poor detection of many organic inputs like Liquid Gold (Gold Leaf).
Practical tips: always measure EC and pH in your actual water after adding the manufacturer’s recommended dose, flush runoff to prevent salt build‑up, and only use generic EC charts for standard mineral feeds — not for novel or organic fertilisers.
