pH measurement

Detailed explanation-1: -For hydroponics, a pH between 5.5 and 6.5 is instead the optimum for plant nutrient uptake, e.g., the optimal pH is between 6.0 and 6.8 for mint [14] while basil did not show yield reduction even at pH 4.0 [15].
Detailed explanation-2: -The most effective way to check your pH is with a digital pH meter. Digital meters come in numerous sizes and price ranges depending on the features included. A digital pH pen is a commonly used pH reading tool for the hobby gardener.
Detailed explanation-3: -Nutrient solution concentration can be monitored and controlled using electrical conductivity measurements. Electrical conductivity is measure of the ionic strength of a solution and can be converted into concentration.
Detailed explanation-4: -A pH sensor will alert you when the pH level drops below 5.5 or rises above 7.0. If you notice a sudden drop in pH levels, you should check your water quality immediately. You can also use an inline pH sensor to measure the pH of your water every day. Control all the nutrients in your hydroponics with lab accuracy.
