Greenhouse plant damage caused by temperature extremes may easily be prevented by a temperature monitor. These products range from local alarms to alert you on your property to dialers that can call a neighbor, your cell or any phone in the world. Conditions such as power failure, humidity extremes and intruders may also be monitored. Some models also allow you to call your greenhouse to check temperatures, power status and other alarm sensors.
Temperature Monitoring Tip.
Locate the temperature sensor in a location that best represents the plants exposure. Often this means placing the probe or sensor within the plants and at the same height as the plants being protected.
