What is pH?

pH is the measurement that tells you how acidic or alkaline a solution is. pH7 is neutral. If the value is lower than pH7, this indicates the solution is too acidic, and if it is higher, it is too alkaline.


Why is the correct pH level important for healthy plants?

To get the most from a plant, it requires the absorption of certain nutrients. The correct pH level enables the plants roots to absorb the central nutrients. If your plant is too acidic or too alkaline, it may cause your plant to stop absorbing these essential nutrients. This is known as 'nutrient lock-out'. You may experience a variety of symptoms if a solution is too acidic or too alkaline. Such as yellowing leaves if the solution is too alkaline.

A healthy pH level for most plants is between 5.5 and 6.3; so slightly acidic. A quick internet search will advise you of the correct pH level for specific plants.

The three things that can change your pH level are :

1. Water.

2. Nutrients.  

3. The actual plant.


Use this kit to manually check pH. Just add water to the tube and add a few drops of indicator. The sample will change colour. Match with the chart to see what pH you're at.
