Each plant has its own water requirements. The soil moisture content can be measured by this moisture meter to give you a good idea whether or not your plant needs water.
 
This moisture meter uses the different conductivity between the two metals at the probe tip to work.
 
Directions for use -
 
	
Wipe the soil moisture probe with a cloth to ensure that the sensor is clean, then insert the probe about 2-4 inches deep to test moisture in the soil. 
 
	
Wipe the probe after each use to keep the metal in the best condition. 
 
	
Designed for use in houseplant compost mixes (not hard garden soils).
 
	
Never put this moisture meter direct into water.
