Garden King Digital Thermohygrometer with Probe: Precision Monitoring for Perfect Environments
You can’t manage what you don’t measure. A standard thermometer gives you half the story, but the Garden King Digital Thermohygrometer measures both humidity and temperature, giving you the complete data you need to optimise conditions for your plants.
Regular monitoring of these crucial metrics is vital for managing your environment, ensuring your plants flourish rather than just survive. This unit is ideal for growers who are keen to control conditions in Grow Tents, greenhouses, or larger plant rooms.
Why It’s a Kit Bag Essential
-
The Probe Advantage: The external probe allows you to measure temperature inside specific microclimates—like your propagator, grow tent, or the center of a dense canopy—without disturbing the environment or opening doors to read the display.
-
Smart Alerts: Never let your plants freeze or overheat again. You can set a custom alarm that goes off if the probe temperature rises above or falls below your desired level.
-
Min/Max Memory: Features a minimum and maximum function, allowing you to track fluctuations while you were sleeping or away at work.
-
High Accuracy: The temperature reading is accurate to plus or minus 1°C, with a resolution correct to 0.1 of a degree.

Pro-Tip: Avoid Stratification Layers of air can separate in your environment, leading to different readings at the floor versus the ceiling. We recommend placing your probe specifically at canopy level to get a true picture of what your plants are actually experiencing, rather than just the ambient room temperature.
