Plants grow best in pH between 5.5 and 6.5. Adjust water pH using pH up/down solutions. Too high or low pH affects nutrient absorption, so maintaining balanced pH is essential in hydroponics.

Water pH influences how well plants absorb nutrients. In hydroponics, the ideal range is 5.5 to 6.5. If the pH is too high (alkaline) or too low (acidic), nutrients lock up and plants can’t use them. We can test the pH using pH strips or meters and adjust it using special pH up/down solutions to ensure healthy plant growth and nutrient availability.
