Wall Thermometer

A wall thermometer is a vital piece of equipment if you are using a greenhouse. It lets you accurately monitor the temperature and temperature is an important factor for healthy plant growth. The most common thermometers consist of a long, clear tube with a coloured liquid inside. The liquid inside the tube expands when it's hot - so the liquid climbs up the tube - and gets smaller when it's cool - so the liquid drops down in the tube. A scale on the wall thermometer lets you read the temperature the liquid has detected.
Thermometers usually measure temperature in Fahrenheit (used mainly in the USA) and Celsius. In degrees Fahrenheit ice freezes at 32 degrees and boils at 212 degrees. Using Celsius to measure the temperature, freezing point if 0 degrees and boiling point 100 degrees.
