Measuring your hydroponic nutrient strength is critical for healthy plants, but it can be confusing.

Is your meter showing EC, PPM, or TDS? And what does it mean when your nutrient bottle's chart is in PPM, but your meter reads EC?

Getting it wrong can lead to underfed or burnt plants.

Take the guesswork out of water quality management with our free and easy-to-use EC to PPM converter.

This powerful TDS calculator instantly translates any measurement for you. The biggest challenge for growers is that not all meters are the same.

That’s why our tool allows you to select the correct PPM scale (0.5, 0.64, or 0.7) to match your specific meter, whether it's from Hanna, Bluelab, Eutech, or another brand. Just enter one value, choose your scale, and see the other two values instantly.

By ensuring you have an accurate reading of your hydroponic nutrient strength, you can feed your plants precisely what they need, every time. Bookmark this page and use this tool to dial in your feeding schedule for faster, healthier growth.
