Product Overview
General Hydroponics® pH Test Kit | 8oz
General Hydroponics® pH Test Kits make pH testing easy. Simply fill a test-tube halfway with nutrient/feed solution, add a few drops of pH Test Indicator and observe the coloration of the liquid in the test vial.
Many experienced growers prefer a pH Test Kit to expensive electronic meters because of its reliability and ease of use, which are important factors when the health of a valuable crop is at stake. Use 3 drops per 5 ml of solution.
