To measure soil PH and moisture, first insert the probe as deep as possible into the soil, leaving about 1 cm above the probe.

The value 1-3(red part) indicates watering is needed, and 4-7(green part) is appropriate. Please adjust the watering time according to the plant species. 8-10(blue part) indicates that it is too WET.

PH is the ALKALINE key, and the corresponding values on the table are 8-3.5. The ALKALINE and ACDIC are respectively acid. The value 7 is basically neutral, and the smaller the number is, the higher the acidity is.

LIGHT: the LIGHT key is the LIGHT intensity. The measurement range is 0-2000 lumens. The higher the value is, the stronger the LIGHT will be.
