This pH calibration liquid is a 30mL single use bottle used for calibrating your pH meter!

How it works

You don't always need a pH meter to grow your favourite plants in our indoor gardens, but having the ability to test your water and adjust pH accordingly will help you optimise your plants growth, and give them a boost that you can't get by simply guessing. We recommend getting a pH meter when you start getting serious about your hydroponic growing journey.

Why is it important to know the pH of my water?

Hydroponic nutrients have a range of different nutrients that plants need to grow. All of these nutrients dissolve in water at different pH levels, furthermore many plants have different pH ranges that they grow best in! If you can know your pH then you can optimise what your plants are getting and make sure that they have everything they need to thrive!

Instructions

Measuring pH is really easy once you're all set up, all you need to do to get an accurate reading is:

  1. Pour the 30mL pH 7 buffer solution into a container, make sure there's enough to cover the "probe" of the pH meter. The probe is the glass bit at the end of the meter, it is the actual element that measures pH.
  2. Place the pH probe in the solution.
  3. Press CAL for 5 seconds. When it flashes 3 times it means the calibration is complete.
  4. Rinse the electrode with water.
  5. Throw out the used pH buffer solution, once it's been used once it cannot be re-used to calibrate pH.
