The thermometer's probe is designed to be long and slender, allowing it to be easily inserted into the soil to various depths. This enables users to monitor soil temperature at different levels, which can be particularly important for plants with deep root systems.

A soil thermometer can be used in a variety of greenhouse applications, including monitoring soil temperature for specific plant species, adjusting irrigation schedules based on soil temperature readings, and tracking changes in soil temperature over time to identify potential issues or optimize growing conditions.
