Flairform pH Up 1L – pH Adjustment Solution


Flairform pH Up is non-corrosive (non HazMat*).  This solves the long-standing safety and handling problems associated with regular pH Up solutions:

  • Concentrated (600g/L potassium carbonate): This provides the equivalent working strength of 400g/L potassium hydroxide.
  • Much safer to use than potassium hydroxide and more environmentally friendly.

    How to adjust pH

    Step 1. Measure the pH: Use either a liquid pH indicator or an electronic pH meter. Before measuring the pH, ensure that the nutrient is well stirred and that the sampling container is clean.

    Step 2. Choose a target pH: It is inconvenient and unnecessary to hold pH at a single point value so choose a target pH that provides both a safety margin and minimizes the amount of pH maintenance. For example:

    ● If your pH tends to continuously rise (the most common trend), then at each adjustment, reduce the pH to about 5.0 using pH Down. This will give you a much larger pH “safety” margin than, for example, 5.8.
    ● If pH tends to fall, at each adjustment increase the pH to about 6.0 using pH Up.

    Step 3. Adjust the pH: Add a small amount (e.g. 1ml per 50 litres) of pH Down / pH Up. Then stir well and check pH. Repeat this process until the target pH is reached. When using pH Up, ensure to pre-dilute the dose at least 100-fold with water before adding to the nutrient.

    Adjusting pH by trial-and-error can be tedious, especially for large reservoir volumes. Refer to Note 1 below for an alternative method.
