The General Hydroponics pH Test Kit provides a simple, economical way to measure the pH of hydroponic nutrient solutions and irrigation water. Its concentrated liquid indicator changes color according to acidity or alkalinity, providing an immediate visual reading without batteries, calibration, or electronic equipment.
The kit covers a broad testing range from approximately pH 4.0 to 8.5. Many hydroponic crops are grown within a nutrient-solution range of approximately 5.5 to 6.5, although the correct target depends on the crop, growing medium, and feeding program.
