THERMO-HYGRO METERS
This soil thermometer is an ideal thermometer to know at all times the internal temperature of the programmer and / or pots indoors and outdoors.
If the earth is very hard or stony, we recommend that you previously make a hole with a long nail or wooden rod to facilitate the subsequent introduction of the thermometer.
HOW TO USE THE ANALOG SOIL THERMOMETER IN SUBSTRATE:
To know the temperature in substrates, you just have to insert the analog soil thermometer and wait about 5 to 8 minutes to get an accurate reading.
