What Are the Best Temperatures for a Greenhouse?

You might be wondering what the ideal temperatures for growing plants in a greenhouse. This question is not easy to answer. Every plant is different and will require different temperatures. The ideal temperature range can also be affected by the season.

These guidelines will help you create a pleasant environment for your plants. The average temperature in a greenhouse should be 80 degrees Fahrenheit during the summer. The greenhouse temperature should be 10 degrees higher than the outside temperature in winter. These are only averages. Your plants will need heat that is more or less depending on their individual needs.

You can make sure your plants thrive by creating a unique climate in your greenhouse.

What are the best temperatures for a greenhouse?

There are four main types of plants. These are classified according their tolerance for heat and cold. The best conditions for tender plants are those that receive eight to twelve hours of sunlight per day.

They can’t withstand temperatures below 60°F and require at least 8 hours of light each day. Tender plants have a longer growing season than those that are hardy. They are also resistant to frost. They must be grown in a greenhouse that has warmer temperatures.

Shade Cloth

Shade cloth is a way to prevent your greenhouse from becoming too hot by blocking the sun. You can either make it knitted or weave it. Because they are not as easily prone to unraveling as woven shadecloths, knitted shade cloths are much easier to maintain. A shade cloth can be washed on a sunny day. It is better to use a pH-neutral detergent without any acidic ingredients. This will increase the durability of your shade fabric.

Shade netting

Shade netting can be used in greenhouses for many reasons. It can, depending on the type, improve light diffusion and provide superior ventilation. Shade netting is useful when growing plants under adverse conditions.

This shade net is light and easy to set up. You can have it custom-made to suit your greenhouse’s measurements. It may take up to a month to create a shade cloth that fits your greenhouse’s size and shape.

Extraction fans

There are many types of ventilation systems that can be used in your greenhouse. The size and type exhaust fans that you require will depend on your greenhouse’s ventilation requirements.

To maximize efficiency and decrease costs, you will want to choose larger-diameter fans that have smaller motor horsepower. A 48-inch fan with a 1/2-horsepower motor can produce an air volume of 12,983 cubic feet per minute. A 36-inch fan, which is a one-horsepower fan and has an output of 11,167 cubic feet per hour, consumes 1,195 watts per hour. Three-phase motors are recommended because they require less electricity and are easier for maintenance.

Bay Leaves

A greenhouse heating system that is high quality will adjust to the temperature of the surrounding air. To ensure the best plant collection possible, your heater should be set to a higher temperature than the ambient air.

A quality heating system can control the temperature and humidity. Proper ventilation is crucial to maintain the greenhouse at the right temperature. You should leave at least 20% of the floor open.

Thermal mass is one of the most efficient and simple ways to raise the temperature in a greenhouse. You can add soil, plants, or even hay bales to increase this mass.

In certain cases, you can soak the hay bales with water to increase their thermal mass. This will allow the greenhouse to regulate its temperature. It is important to place the fans at least 40-50 feet apart to get the best HAF results.

Ventilation

You may need to change your ventilation system if your greenhouse is experiencing extreme heat. Natural ventilation depends on the outside climate. Mechanical ventilation can be controlled by temperature so that you can control when it runs.

A thermostat that monitors the temperature of the greenhouse is best to achieve the best results. The sensor should be located near the top of your greenhouse where the plants will be exposed to the outside air. You can then ensure that the temperature and airflow are equal.

Bay Leaves for a Greenhouse

When potting bay leaves in containers, ensure that there is a good drainage system. Overwatering the plants can cause leaf spots. This is a disease that affects plants having sodden roots. This can stunt the growth of new leaf.

Make sure your container is well-drained and has extra drainage holes. You may need to spray pesticide if you overwater your plants.

Ventilation Fans

By measuring the cfm, you can calculate the amount of air movement inside a greenhouse. Fans should operate at the same speed as air movement to maintain constant temperature. To avoid air turbulence, choose fans that have a higher static pressure rating than the greenhouse. The fan size must be larger than the static pressure. You can increase the greenhouse’s air volume with a smaller fan.

First, determine the greenhouse’s volume to find the correct size fan. Multiply the length by width by height to calculate the volume. Divide this number into the required airflow rate once you have obtained it. This will determine the number of fans that you will need.

Next, determine the greenhouse’s static pressure. The static pressure is calculated by subtracting the greenhouse’s height from the highest point of the structure. Divide this number by 2.2 to determine the number of fans that you will need.

You can now determine the size of your greenhouse and its static pressure so that you can buy the right size fan.

Conclusion

To maintain the right temperature, a greenhouse must be properly ventilated. There are many ways to adjust the ventilation system to correct temperature problems. To regulate temperature, thermal mass can be added. Hay bales can also be added to the greenhouse. To increase the temperature, bay leaves can be added to your greenhouse.
