Why we use pH meter in Hydroponic?

A pH meter is used in hydroponics to measure the pH level of the water and nutrient solution. pH is a measure of the acidity or alkalinity of a solution, with a pH of 7 being neutral, a pH less than 7 being acidic, and a pH greater than 7 being alkaline.

In hydroponics, the pH level of the nutrient solution is important because it directly affects the ability of the plants to absorb nutrients. Different plants have different optimal pH levels, and if the pH level of the nutrient solution is outside of this range, the plants may not be able to absorb the nutrients they need to grow.

By using a pH meter, hydroponic gardeners can easily and accurately monitor the pH levels in their nutrient solution and make any necessary adjustments to ensure optimal growth of their plants. This allows them to provide their plants with the proper nutrients they need to thrive, leading to healthier plants and higher yields.
