Hydro Digital Thermometer - Probe for temperature and humidity

3-in-1 Digital Thermo-Hygrometer for Optimal Control of Your Grow

Master the climate of your grow space perfectly with this high-precision digital thermo-hygrometer featuring simultaneous triple measurement. Optimize your plants' growth with comprehensive tracking of ambient and root temperature and humidity.

Simultaneous Temperature and Humidity Measurement with Professional Accuracy

Monitor critical conditions in real-time thanks to simultaneous temperature-humidity measurement in three distinct zones. The system captures ambient data via the main unit and root conditions with the 1.5-meter wired probe. This prevents thermal and water stress that reduce yields and quality by 30 to 50%.

The high-definition LCD screen clearly displays all values continuously, allowing instant visual control even in darkness. The ±1°C and ±5% humidity accuracy guarantees reliable measurements for precisely adjusting ventilation, heating, and humidification. Your plants benefit from an optimal stable environment for growth.

External Amphibious Probe for Substrate Climate Control

Directly measure root zone conditions with the 1.5-meter waterproof amphibious temperature probe. This specialized probe monitors substrate humidity and temperature, a critical area often overlooked by beginner growers. The flexible cable allows strategic positioning at different measurement points according to your needs.

The probe's moisture resistance allows use in hydroponics, coco, soil, or rockwool without risk of damage. The precise root measurements alert you to substrate temperature variations that impact nutrient uptake and root health. You anticipate problems before they affect growth.

Minimum-Maximum Memory Function for Historical Analysis

Analyze climatic condition changes with the integrated memory of extreme values recorded automatically. The system stores minimum and maximum temperatures and humidity rates reached, revealing hidden variations during your absences. These historic data allow identifying critical periods and adjusting ventilation, lighting, or heating.

The reset function allows restarting recordings after each environmental adjustment. You control the effectiveness of your changes and validate the recovered stability of your grow room. Experienced growers use this data to optimize day-night cycles and maximize photosynthesis.

Easy and Versatile Installation for All Growing Spaces

Quickly install your digital thermo-hygrometer with the dual mounting system: wall mounting with screws or free positioning on an integrated stand. This versatility adapts to all types of grow spaces, from small cabinets to large professional rooms. The included batteries allow immediate startup without preparation.

The compact case and rotatable screen facilitate reading from different viewing angles. The robust construction withstands humid growing environments and ensures exceptional longevity. You invest in a durable measurement tool that will accompany many years of successful grows.

In my 15 years of indoor growing experience, I recommend placing the external probe halfway up the canopy, where humidity often stagnates. This is where molds mainly develop if conditions are not controlled. I also advise checking minimum-maximum values every morning to detect nocturnal variations often missed by growers. A temperature gap greater than 8°C between day and night generally indicates a thermal regulation defect that must be corrected quickly. Joseph – Director of GrowLED
