PH test kit

You need a PH meter when you need to keep track of the acidity of the water and is recommended for anyone who wants to grow. 

If the PH value is wrong, the plant will not be able to absorb nutrients as it should and the result will be worse.

Liquid-based PH testing is a safe, fast, reliable and accurate test without batteries.

Fill the container halfway with the nutrient solution and then drip in 2 drops. Replace the cap and shake the tube.

Then compare the color of the liquid in the tube with the bottle's PH table and you will see the PH value. The table goes from 4.0-8.5 in PH value.
