Description

This General Hydroponics pH Test Kit consists of a test tube for taking a sample, a reagent liquid to add to the test tube and a colour chart showing the pH between 4.0 and 8.5, against which the colour of the liquid in the test tube is matched. The pH should be tested after adding Nutrients as Nutrients can change the pH of the water. A high PH can reduce the availability of iron, manganese, boron, copper, zinc and phosphorous in plants. A low PH can reduce the availability of potassium, sulphur, calcium, magnesium and phosphorus.

If the pH moves out of the desired range, it can be lowered by the addition of pH Down to the solution, or raised by adding pH Up.

 

INSTRUCTIONS FOR USE:
  • Fill the vial (supplied) with your nutrient solution,
  • Add 2 drops of test solution & replace cap without direct contact (do not use your uncovered fingers) in order to avoid contamination of results.
  • Shake briefly, then reference the pH colour chart on the side of the bottle.
