Check your hydroponic water conditions with pH test strips.

pH affects how easily plants can take up nutrients from the water. These test strips give home growers a quick way to check pH levels occasionally — especially when setting up a fresh reservoir, refreshing nutrient water, or troubleshooting plant growth.

What's Included

  • 80 pH test strips
  • Colour-chart style pH testing
  • Suitable for checking hydroponic water
  • Useful for FlowGrow towers and home hydroponic setups
