##How to Measure pH and EC in Growing Mediums
Measuring pH and EC directly in your growing medium helps you understand what’s really happening at the root zone. This is key to detecting nutrient imbalances early and making precise adjustments to your feeding and watering.
In this guide, we cover different methods to measure pH and EC in soil, coco, and other substrates, what each method actually reflects, and how to interpret your results correctly.
Why Measuring in the Medium Matters
Checking pH and EC in your medium allows you to
• understand root zone conditions more accurately
• detect salt buildup and nutrient imbalances
• adjust feeding strategies with better precision
• avoid overcorrections based on misleading readings
Sometimes runoff or input measurements don’t tell the full story. Knowing what’s happening inside the medium gives you a clearer picture.
