Features: -1.Measures moisture content of soil,let you know when need to water the plant. -2.Helps you determine if plant is getting adequate light. -3.Helps you control the soil PH level. -4.No batteries needed. Important Tips: -1.Do not touch the stone or hard rock soil,if the soil is too hard and dry,easy to damage the probes. -2.Design for testing soil only. -3.After using, need to clean and wipe the probes. -4.Measurement of moisture and pH must be viewed while the unit is in the soil,the tester must be kept in the soil for 10 minutes or more.
