Hy-Gen pH Indicator Kit – Hydroponic pH Test Kit

Keep your nutrient solution pH on track with the Hy-Gen pH Indicator Kit, a simple and convenient way to check pH in hydroponic nutrient solutions. Using a concentrated indicator solution and easy-to-read colour chart, the kit provides a quick visual pH reading without the need for a digital meter or calibration.

Regular pH testing helps you monitor changes in your nutrient solution and maintain conditions where plants can access the nutrients they need. Ideal for routine testing, the Hy-Gen pH Indicator Kit is a practical choice for both new and experienced hydroponic growers.

Simple Visual pH Testing

The Hy-Gen pH Indicator Kit makes testing straightforward. Simply take a sample of your nutrient solution, add the indicator solution and compare the resulting colour with the supplied pH chart.

The colour-based system makes it easy to perform regular checks and monitor changes in your nutrient solution over time.
