With this practical pH meter, you can quickly and easily check the acidity of potting soil or garden soil. Insert the probe three-quarters into compacted, moist soil and wait 60 seconds until the needle shows a value. A pH value around 7 is ideal for most plants; if the pH is lower than 5.5, you can add lime to make the soil less acidic. An essential tool for healthy plants and lush growth!
