Why use a pH & EC meter?
✔ Ensures optimal nutrient absorption
✔ Prevents deficiencies and overfeeding through accurate measurements
✔ Improves the health and yield of your plants
✔ Essential for growers working with soil, coco and hydroponics
What do pH & EC meters measure?
pH value: acidity of the nutrient solution
The pH value determines how well plants can absorb nutrients. An incorrect pH can lead to deficits, even if all the necessary nutrients are present.
- Ideal pH values per substrate:
✔ Earth: 6,0 - 6,5
✔ Coconut: 5,8 - 6,2
✔ Hydroponics: 5,5 - 6,0
EC value: conductivity of nutrients
The EC value (Electrical Conductivity) measures the amount of dissolved salts in the nutrient solution and indicates how many nutrients are available to the plant.
- Ideal EC values per growing stage:
✔ Seedlings & cuttings: 0.4 - 0.8 EC
✔ Growth phase: 1.0 - 1.6 EC
✔ Flowering phase: 1.6 - 2.2 EC
Types of pH & EC meters

How to use a pH & EC meter?
- Calibrate the meter regularly - Use pH calibration liquids and EC solutions for accurate measurement.
- Measure the nutrient solution - Dip the electrode into the water and read the pH and EC values.
- Adjust pH if necessary - Usage pH- (min) or pH+ (plus) to achieve the right balance.
- Check your EC value - Add nutrients if the EC is too low or dilute the solution if the EC is too high.
- Store your meter correctly - Store the electrode in storage liquid to prevent dehydration and inaccurate measurements.
