Temperature & Humidity Controllers
Unfortunately, most hydroponic growers cannot be around to monitor a thermometer all day to manually activate fans or other atmosphere control devices. Luckily, humidity control and temperature control is possible by using a temperature and humidity controller. These devices make …it much more manageable to lower humidity in a grow tent or room by automatically activating your hydroponic air conditioning systems.
HTG Supply offers several models of temperature and humidity controllers that come with manufacturer warranties against defects.
