Here are the steps on how to keep a greenhouse cool: checking the temperature, ventilating, dampening, shading, watering, and planting. Does the scorching heat make your plants wither and lose their optimum health condition? Is keeping a greenhouse cool necessary?

Although greenhouses naturally capture heat for the plants, they also need some cool down. Developing a greenhouse despite the weather truly is a challenge for gardeners. Most gardeners reject the idea of keeping a greenhouse in times where hot temperature arises.

The rising heat and humidity emerge the temperature of winds to become warm, making it hard for gardeners to grow plants in a healthy condition. However, resorting to ideas that control the environment that plants need is possible.

Don’t you worry, in this article, let’s find out how to keep a greenhouse cool.


Keeping Your Greenhouse Cool

As time passes by, seasons change, and hot weather arrives. Indeed, it is a challenge for greenhouse gardeners to manage the temperature that plants need inside a greenhouse. This is why keeping your greenhouse cool is necessary since it will keep your plants in good condition despite the heat.

Regardless of this matter, letting your plants wilt and die due to the heat is still preventable. Here are some practical and straightforward hints on how to keep a greenhouse cool:


#1 Temperature check

Before cooling down your greenhouse, you must run a temperature check inside your greenhouse first. It is crucial to consider the temperature first since plants should maintain a proper temperature- not too cold, not too hot.

It is also wise to consider first your geographical location. Warmer places might require more complex cooling equipment to cool your greenhouse down.


#2 Proper greenhouse ventilation

An appropriate airflow that provides plants chilly winds to resist the heat is one significant move to keep your greenhouse cool. Ventilations such as roof vents and side vents create pathways for the air to move and cool down plants that are overheating.

Proper ventilation controls the air circulation inside a greenhouse, which keeps the temperature lesser and cools down the area enabling the plants to prevent overheating. Deficient air circulation can lead to plants’ unhealthy growth conditions and problems regarding humidity or worst, wilting of plants.

The use of fans and vents is highly recommended since it ensures plants’ proper temperature despite the hot weather.

Opening the doors of your greenhouse can also cool down the temperature inside. Leaving the doors open during the night will also help the plants take some cold air since the wind is more relaxed. However, you must be careful if you will do so!


#3 Dampening down a greenhouse

Dampening down your greenhouse creates enough humidity due to water evaporation that prevents plants from overheating. Pouring water to the surface and walls of your greenhouse every morning controls the moisture and cools down the greenhouse as well.

Using a hose to dampen down your greenhouse’s surface and walls are more accessible than pouring water manually. By doing this procedure, you can rest assured that your plants will not suffer heat problems and will grow in a healthy condition with proper care accompaniment.


#4 Greenhouse shading

Greenhouse shading is an affordable and more comfortable procedure to keep your greenhouse cool. The use of external shade and internal shade netting enables the plants to grow correctly without experiencing heart problems, too.

External shading is merely covering the greenhouse’s roof with a large piece of the plastic weave. You can weigh the edges down by attaching large stones or bricks which should reach the floor for future adjustments.

Internal shading is fixing a plastic weave shading inside your greenhouse. Using dark shade nets could absorb the energy and convert it to heat. You don’t want your plants to get toasted, so using light-colored ones such as white or green is highly suggested.


#5 Watering regularly

It is imperative to water your plants regularly since plants need water to grow. Plants also undergo a process that is almost similar to a human’s perspiration called transpiration.

When plants lose moisture through the pores in their leaves, this cools down the leaves’ surface. Thus, preventing them from wilting.


#6 Tree planting

The most practical way to keep your greenhouse cool is by planting trees. Planting more trees around the greenhouse creates shade that will prevent the greenhouse from capturing heat.

Typically, trees grow for some years to provide shade, so increasing them earlier would be wise.

Adding trees outside the greenhouse makes it even greener and a sight to see! After all, how much you care for the environment shows how much care you have for yourself.



If you’re the gardener, you’re responsible to take care of your plants; it’s very elementary. Keeping your greenhouse cool during the humid days creates an environment where your plants can grow healthy.

Keeping a greenhouse cool is more comfortable and enjoyable if you are committed to your work. Also, remember to consider your location and the weather before cooling your greenhouse.

Provide your plants the proper temperature they need. Keeping them cool during the hot weather gives them a better growth condition. Always remember, proper care leads to adequate growth. Following the hints on how to keep a greenhouse cool will certainly help your plants grow in a healthy condition.
