These handy pH test indicators give a quick reading of the pH of solutions making them ideal for the grow room.
The VitaLink ESSENTIALS pH test indicator kit uses a solution known as universal indicator to change a small sample of your nutrient solution to a different colour. Compare this colour to the spectrum chart to indicate what pH your solution is reading at. Although not as accurate as using a pH meter to analyse your nutrient solution, this indication kit is a quick, precise and cost efficient measure giving over 100 readings.
