### ⭐⭐⭐⭐⭐ Great thermometer for plant environment control
*by R***. on February 16, 2026*

Great thermometer. The VPD ability is key as I need a very specific range for my plants. It also allows me to know leaf surface temperature, which is another key variable for environmental control. Easy to use and read, great value for the price.
