  • Accurately measures the temperature and humidity in your environment.
  • Internal and external thermometer.
  • Maximum and minimum temps.

Stable temperatures are one of the key elements for perfect results.


The max/min function allows you to keep track of the extreme temperatures in your room whilst your not there. If lights are off during night time, the ambient temperature will drop significantly compared to when lights are on. The minimum function will allow you to see how low the temperatures can go during lights off , whilst the maximum function allows you to see how high the temperatures can go during lights on.


As the seasons change, it is very important to constantly measure the fluctuations of temperature in your environment since the ambient temperature can greatly affect temperatures inside the growing environment.


When temperatures are too low you can heat the growing environment with a simple greenhouse heater or a space heater for larger spaces. If temperatures are too high, you should consider the use of different techniques to lower the temperature. Oscillating fans help increase plant transpiration and cool them down through evaporation. If growing in a hydroponic system, chillers can be installed in order to reduce temperatures within the reservoir.
