Your greenhouse can vary during the different seasons. In the heat of the summer your greenhouse could easily reach over 100 degrees if you don’t use ventilation in the greenhouse. Using a thermometer to track your temperature changes will help you to help you control the environment in the greenhouse. When you watch your thermometer during the cold winter months you also will know when to turn the heat up or when to add additional heat sources to your growing environment.
There are different types of thermometers that gardeners use. One thermometer will measure the temperature in the greenhouse. Another type of thermometer will measure the humidity in the greenhouse and yet another will measure the high and the low temperatures in the greenhouse. A hobby gardener will become dependent on a thermometer to control the environment for the plants. One of the best thermometers to have is one that will tell you the high and low temperatures. This can help you use your ventilation more during the highest temperatures and to know when your heat is not sufficient. The mercury in your thermometer will become your best friend when your plants are looking a little wilty and you don’t know what happened. If you find that the temperatures in the greenhouse had gotten too high then you can prevent further damages to the plants.
The best place for your thermometer is one the bench where your plants sit for the best readings. Sometimes the temperatures could be higher towards the roof at the peak of the greenhouse but where your plants are on the bench will be better regulated. If you are interested you can purchase soil thermometers that will tell you the temperature of the soil in the greenhouse. If you have plants and beds of flowers that are on the lowest benches or on the floor of the greenhouse, you may want to know how cold or how warm the soil is for these plants. Keeping all of your plants and flowers in the greenhouse at a warm growing temperature of at least forty degrees will ensure that your plants will thrive.
