General Hydroponics® pH Test KitGeneral Hydroponics pH Test Kits make pH testing easy. Simply fill a test tube halfway with nutrient, add a few drops of pH Test Indicator and observe the coloration of the liquid in the test vial. Many experienced growers prefer our 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 5ml of solution.

Lightweight but heavy in style and quality!
Color: Black+White
Bracelet fits well on wrist, not too heavy at all pretty light, easy to put on and quite stylish! It’s shiny and has great quality for being so lightweight. Wore it for awhile and it’s both comfortable and dressy! Simple jewelry but its use of cool shapes makes it seem quite expensive!
