There are four types of greenhouse shading you can use to keep things cool in your greenhouse. They are greenhouse shade paint, greenhouse shading blinds, greenhouse shading cloths, and greenhouse shading netting.

All these four types of shading are important not only for cooling but also for preventing excess light from getting to your plants. Remember, excess light is as bad as poor lighting. So by keeping your things cool using shading, you will also be protecting the health of your greenhouse plants.

In this post, you will learn the four best ways to keep things cool in your greenhouse with greenhouse shading.

Let’s begin.

The Four Best Ways To Keep Things Cool In Your Greenhouse Using Shading

1. Greenhouse Shade Pain

Greenhouse Shade Paint

You can use greenhouse shade paint to keep things cool in your greenhouse. The use of shade paints is regarded as one of the cheapest ways to keep plants cool in a greenhouse. This is because it simply involves buying and applying paint unlike other methods of keeping things cool that involve purchasing a special material and installing it.

There are several types of greenhouse shade paints that you can utilize to make your greenhouse cool especially during summer. Most greenhouse shade paints have to be mixed with water before being sprayed or applied.

Most greenhouse shade paints are white. This is because white is the best color if you are aiming to reflect light and heat. White surfaces are known to reflect sunlight energy more efficiently than black or dark surfaces, which are known to absorb sunlight and its heat energy.

Therefore, if you want to buy a greenhouse shade paint, you should make sure what you buy is white or bright in color.

Shade paint is normally temporary. It is something that can be wiped off using a duster. Therefore, you should not be worried too much about the appearance of your greenhouse after summer.

It is important to note that the paint can be applied on all glazing types including plastic, polycarbonate, and glass.

Some of the most popular greenhouse shade paints currently available in the USA include the Bayer Garden Coolglass and the Vitax Summer Cloud Greenhouse Shading. More details on the Bayer product below the paragraph below.

The best time to apply greenhouse shade paint to your greenhouse walls is between March and October when the sun is very hot.

The only drawback to using a greenhouse shade paint to make things cool in your greenhouse is that you may need to reapply it every half-a-year or one year.

2. Greenhouse Shading Blinds

Your cucumber leaves are most likely turning white because of powdery mildew (a fungal disease). They could also be turning white because of excess moisture or blanching. In this post, you will learn everything important about these things that can make cucumber leaves turn white and how to deal with them. Let’s begin. The things that can make cucumber leaves turn white and how to fix them 1. Powdery mildew When you see your cucumber leaves turning white, ninety percent of the time the cause is powdery mildew. This is because it is one of the most common fungal diseases. Virtually all crops, shrubs, ornamental trees, and plants can be affected by it. The only good thing about the disease is that you can easily identify it and there are several ways to fix it. Signs to look out for To know if the white in your cucumber leaves is caused by this disease, you should look at for certain signs. First, you should look out for white powdery spots covering entire leaves. The spots also usually appear on other parts of the affected plants including flowers, fruits, and stems. So check if your cucumbers have white powdery spots all over them to confirm if they have been attacked by this disease. Second, you should look out for signs such as leaf browning and curling. This often occurs at an advanced stage of the disease. Lastly, you should also look out for early bud drop, which is another characteristic sign of this disease. Luckily, the signs of powdery mildew often look worse than the real damage the disease causes. So you do not need to panic when you discover them. Moreover, the disease is rarely fatal. What to do after identifying the disease Once you are very positive that the white spots on your cucumbers are caused by powdery mildew, you need to act immediately. Your first action should be to remove the conditions that increase the likelihood of mildew formation. The conditions include poor air circulation, over-fertilization, and poor lighting. By improving air circulation through spacing your cucumbers better, preventing over-fertilization by using a slow-release fertilizer, and addressing poor lighting by trimming overhead trees/plants, you will make the conditions less favorable for mildew formation. The second action you should take should be to address the disease. There are several ways you can do this. See the section below. How to fight powdery mildew in cucumbers Once you have detected powdery mildew in your cucumber plants, you should act immediately to stop the disease. If you do not act immediately, the disease could spread and negatively affect your entire cucumber crop. I. Commercial fungicide product. The easiest way to fight powdery mildew is to purchase and use a commercial fungicide product. Make sure the product is natural and it is not going to make your cucumbers toxic. While using commercial fungicide products to fight powdery mildew is easy, eliminating the disease is not a given. You have to continue being on the lookout for signs of the disease and to take action the moment you discover something. II. Baking soda. Baking soda is a popular safe and organic solution for mildew. When combined with liquid soap, it can easily prevent a mildew outbreak because it kills the fungi responsible for powdery mildew. To make a baking soda solution for mildew, mix a tablespoon of the chemical with liquid soap in 3.5 liters of water. Spray the solution extensively on your plants especially on the white spots to end the disease. III. Potassium bicarbonate. This is also a solution for ending powdery mildew. The best thing about this chemical is that it kills mildew fungi on contact. The second best thing about it is that it can be used in organic farming. So it is certainly a wonderful option for fighting powdery mildew. IV. Vinegar. Vinegar can fight powdery mildew because it has acetic acid in it. To make a vinegar-based solution for controlling mildew, you should add 3 tablespoons of vinegar to 3.5 liters of water. When using vinegar, be careful not to burn your cucumbers by putting too much of it in your solution. V. Milk. Milk is believed to contain compounds that kill powdery mildew. It is also believed to contain compounds that improve the immune system of plants. Several experiments have shown that applying a solution made of 33 percent water and 66 percent water, can have devastating outcomes for the fungi responsible for powdery mildew. VI. Neem oil. If you are not new to the gardening world then you surely know that neem oil is the panacea for many plant pests and diseases. Neem oil is gotten from the neem tree that is found in East Africa and India. It is an effective killer of many pests and diseases and at the same time, it does not bear any harm for humans, animals, plants, and many beneficial insects. When applied, this solution can control and even eliminate powdery mildew. As you can see above, you can control mildew in several ways. However, while the disease is controllable, you are better off taking action to prevent it than to try and control it. 2. Excess moisture Excessive moisture can also make cucumber leaves to turn white. This is because when there is too much water in the ground, the nutrients quickly leach out making it difficult for leaves to maintain their normal color. The leaching of nutrients often turns green leaves white or pale yellow. To correct the lack of nutrients in the soil, you need to first improve the soil and/or reduce watering to ensure nutrients do not leach quickly. And then you need to apply a phosphorus-rich fertilizer to correct the situation. A good example of a phosphorus-rich fertilizer that you can use is the Espoma TP6 Triple Phosphate Fertilizer that is found on Amazon. 3. Accidental blanching In horticulture, blanching is a method used to produce vegetables that are pale in color. The method involves covering shoots to block sunlight, prevent photosynthesis, and stop chlorophyll production (hence the pale color). When you accidentally position your cucumbers in such a way that some of the leaves or the cucumbers themselves do not receive enough sunlight, they will turn pale/white with time. The foliage of your cucumbers and/or neighboring plants can also block sunlight from reaching your cucumber leaves resulting in pale/white leaves. To undo blanching, you should make sure light hits all the leaves on your cucumbers. You can do this by moving your cucumbers, trimming them, or trimming neighboring plants or trees. The final note As you can see, three things can make cucumber leaves turn white – powdery mildew, horticultural blanching, and excess moisture. By implementing the solution or solutions I have presented under each cause of cucumber leaf whitening, you can save your cucumbers.

You now know you can keep your greenhouse cool using a special paint. In this section, you will learn you can also do the very same thing using shading binds.

According to some experts, shading blinds are very popular in the gardening world for use as temperature control.

There are two major types of blinds – internal blinds and external blinds. Internal blinds are designed to be installed inside, while external blinds are designed to be installed outside. Both blinds can be operated to provide shading or let the sun in.

Blinds are often made of a material that prevents the sun from shining through them. This is what makes them provide a fabulous cooling effect.

According to experts, the best shading blinds are external shading blinds. This is because they prevent the sun from getting into the greenhouse via the glass panels. This means it blocks both the direct sun and its heating effect to provide maximum cooling. In contrast, internal blinds allow sunlight through the panels and block them after they enter. This provides some cooling but does not prevent the sun from increasing the temperature inside the greenhouse by a few degrees. Therefore, external shading blinds are the best.

However, while external shading blinds provide better cooling, they are usually more expensive than internal blinds. They are also usually more difficult to automate and maintain when compared to internal blinds. So both internal and external blinds have got pros and cons.

Examples of greenhouse shading blinds

There are several greenhouse shading blinds available on Amazon and other online sellers. The most famous one is described below.

Eden Greenhouse Roller Blinds

These roller blinds are relatively popular and well-rated. They are made of a material that is special and synthetic. It can reduce the intensity of the sun by a whopping 60 percent.

These roller blinds are easy to install. This is because they come with suckers that can be easily fixed onto glass walls for their attachment.

These roller blinds measure 575 mm by 1900 mm. Therefore, if you need a bigger area to shade, you will need to buy more.

3. Greenhouse Shade Cloth

Greenhouse Shade Cloth

You now know you can use a special paint or special blinds to provide cooling in your greenhouse. In this section, you will discover that you can also provide cooling using shade cloth.

Many people prefer using shade cloth rather than using shading paint or shading blinds. This is because of three key reasons.

First, shade cloths are cost-effective. They are cheap and when properly installed and cleaned, they can last for many years.

Second, there are many types of greenhouse shading cloths. Each of them has a specific shading value. Therefore, if you want less than 50 percent shading, you can simply search for it, buy it and install it. If you want one that offers maximum protection fun, you can easily find it too, buy it and install it.

Lastly, shade cloths are liked because they are easy to install and to maintain. If your greenhouse is small or moderate, you will find it easy to install a shade cloth.

And when you need to take it down, you will also find it easy to do so. No need to call someone to help you or get a professional company to do the work for you. It is easy to maintain shade clothes because they are simply cloths that can be washed and dried.

An Example Of A Greenhouse Shading Cloth

This shading cloth is found on Amazon.com, where it has a decent rating of 3.9/5.0. This shows how good it is.

It is made of a special material that is UV resistant and blocks as much as 70 percent of the sun from reaching the greenhouse.

This shading cloth offers protection against the harsh sun and insects. The best thing about it is that it is lightweight and extremely tough and durable. It is something that will serve you for a long time if you take good care of it.

4. Greenhouse Shade Netting

Greenhouse Shade Netting

You can keep things cool in your greenhouse using shade netting. A shade netting is a kind of like a greenhouse shading cloth. The major difference between them is the material used. In fact, because of their similarity, some people consider greenhouse shade netting to be just a version of greenhouse shading cloth. However, in my opinion, the two are different.

A greenhouse shade netting is made of polyethylene fabric that is strongly knitted making it tougher than most greenhouse shading cloths. Greenhouse shade netting is tougher because it protects against both the sun and strong winds.

It protects against strong winds by reducing their speeds.

It also protects greenhouses from snow loads.

Greenhouse shade nettings come with various sunblock percentages. Some block only 50 percent, while others block as much as 85%.

Most shade nettings can last for as many as ten years.

An Example Of A Greenhouse Shade Netting
Easy Gardener Screen Fabric Greenhouse Netting

This wonderful product is designed to provide 75 percent sunblock. It has the potential to reduce greenhouse temperatures by as many as 15 degrees. Therefore, if you have a greenhouse crop that needs to stay cool especially during summer, it is a good option to consider.

The netting is black in color and measures 20 feet by 6 feet. So it is big enough for many non-commercial greenhouses.

According to the manufacturer of this netting, you can use it to provide your greenhouse with shade or as a windscreen. You can also use it as part of your fence to increase privacy. The manufacturer also states that it is easy to install and can easily be cleaned using a garden hose.

This product is available in many sizes and colors.
