If you grow plants under grow lamps in a carefully controlled temperature and humidity environment, the slightest change can effect the finely tuned atmosphere of your room and ruin a crop in no time. Maintaining an optimum growing temperature is vital, and this is where the Temperature Sensor for the Dimlux Maxi Controller is invaluable. Instead of constantly monitoring the temperature of your growing room manually, the Temperature Sensor takes care of it for you. If it senses the temperature drop, it increases the light until optimum temperature is reached; if it senses the temperature rise, it decreases the lights until the best growing temperature is reached. Take the hassle and worry out of maintaining your grow-room environment.
