These liquid pH testers are a very economical way to monitor the pH level of your nutrient solution. Each kit consists of 20ml of reagent, a small phial and a colour chart to translate your result into a pH value between 4 and 10.

Whilst these kits may not be sufficient for the more experienced grower demanding a very accurate pH reading, they do provide enough information for the smaller-scale hobbyist to maintain the acidity within an appropriate range.
