Table of Content


It is important to protect greenhouses against overheating during the growing season. In addition to greenhouse air circulation, shading also lowers greenhouse temperatures by decreasing the light passing.
Plant health can be improved by reducing the effects of high temperatures on sensitive plants, ensuring the growth of most plants, and increasing the yield of plants.

There are many shade cloth options available, making it hard to determine what is the best shade cloth.

Here are the criteria we suggest using to determine the best one for your greenhouse:

What is Greenhouse Shading?

Hot temperatures can damage plants in your entire greenhouse.

Shade cloth reduce temperature and Shading cools greenhouse floors during the hot season. Besides reducing the inside temperature the greenhouses also reduce the amount of sunlight that enters the atmosphere. Good ventilation helps to keep the temperature at the right levels, although the sun’s energy does not reflect off the air. It builds rapidly in greenhouses, averaging temperature and posing a threat to too many plants.

Shading in the Greenhouse is so important, that growers who want to get the best out of their yield, shade their greenhouses.
It is a common practice in hot countries and during hot seasons. Greenhouse shading also helps to reduce water loss through evaporation.

How shade cloth can increase plant production?

We have all been told that it was a bad idea to use shade cloth for vegetable gardens or greenhouses. Sun is essential in the garden! But plants don’t need too much sun.

Research in the field has actually demonstrated how it may enhance photosynthesis, particularly during hot seasons. The idea seems counter-intuitive.
But it is really possible to know how photosynthesis occurs.
The right amount of sunlight and temperature is indeed necessary for more rapid growth.

However, higher temperatures and too much sun’s rays would reduce the yield of plants on the contrary. Shade cloth reduces temperature and increases the yield of plants effectively.

In a shade house, a shade screen is used on the top which protects plants from too much sunlight. It also allows air to circulate which prevents the leaves from overheating.
As a result, it helps the plants to produce more food and grow faster.

Using shade cloth actually helps to increase the production of shade-loving crops such as lettuce and spinach.

Shade cloth can help plants grow more quickly in the spring by protecting them from late frosts that can kill young plants.
It can protect plants from wind damage, which can be costly to repair and cause further damage to the plants themselves.

Different plants require different levels of shading. The shading rate of shade nets also varies according to the climate. To ensure a better harvest, choose a shade net that suits your planting needs.

For example, greenhouses in South Africa use shade nets that are about 10- 15 % higher than those used in Australia.

What is the most effective shade cloth?

Some shade cloths are more effective than others in reducing the amount of heat and light that passes through to the plants. The best shade netting will have a high heat rejection and low light transmission.

Plants cannot endure the summer heat. In some places with hot temperatures such as Las Vegas or San Antonio, your plants may be dehydrated. The clothing acts as a protection for plants and protects against sunburn and excessive levels of water condensation.

Good crop ventilation is provided which eliminates the need for expensive cooling devices. Before you start looking at purchasing greenhouse shade cloths, make sure you understand their characteristics and materials.

Here are the 4 key points you need to know.

What color shade of cloth should I use?

Different shade cloth color absorbs and reflects sunlight in different ways depending on their application.

greenhouse shade

The common shade cloth colors we often see are black, white, grey, red, and green shade cloth.

For gardening purposes, green shade cloth is the more common color. White, tan, and black are available.

At the same density, a darker shade of cloth will produce a higher shading rate.

So when your plants need a high shading rate and don’t have particularly high light requirements, you can choose darker colors.

Advanced Shade cloth color often contains aluminum foil, which reflects the light and heat in a way that is more significant than the color itself. It can be a replacement for darker clothes.

This material also has the function of preventing the loss of nighttime temperature in the greenhouse.

Black shade cloth vs. White shade cloth?

On the face of it, it’s a simple question: black or white? But in reality, there are many factors to consider when choosing between these two options.

White shade cloth is a highly reflective material and will reflect sunlight and heat, which can be great for keeping your plants cool during the day and for increasing visibility in your greenhouse at night. White also does not attract bugs like black does because it does not absorb heat as much as other colors do.
White shade cloth allows heat to radiate onto plants. In a meantime it provides cooling effect too. It is one of the ways to cool a greenhouse without electricity !
If you have flowering plants, you will benefit from using white shade cloth.

Black sunshade cloth can absorb heat as well as block light in contrast to the color of white.

In places where the temperature difference between day and night is small, a white sunshade cloth may be sufficient to block high temperatures during the day.

If the temperature has a huge difference between day and night, the black sunshade net can make up for the lack of heat at night by absorbing heat.

What shade percentage of sunshade cloth should I use?

The shading percentage of sun shade cloth depends on the netting density and weaving methods.

Shade cloth density measures the amount of light the cloth block. The greater the percentage the better the shading effect.

Shade cloth with 10 % of shade rate can prevent only 10% of sunlight with high light penetration and shade cloth of 90% can block 90% of sunlight.

How much sunlight do plants need?

Different plants need different amounts of sunlight.
For most plant species, 40-60% shade reduces sun exposure and provides enough sun energy to stimulate photosynthesis.
Shade cloth is used to give shade, this is the most important feature to take into account.
Although “density ratio” sounds technical compared with color and fabric type, shade fabric percentage should be understood.

Density also plays a crucial role in determining the shade cloth percentage in greenhouses used.

The most commonly used percentages of shade cloth:

30% Shade Cloth
Some crops, vegetables, heat-tolerant plants, and fruit may use cloth which provides 30% shading.

30% shade cloth for tomato

Vegetables such as tomatoes and eggplant have good shade-tightening under 30% and fruit such as peaches have good shade coverage.

Some flowers, such as roses, can also use shade cloth with this shading rate.

40-60% Shade Cloth

40-60% Shade Cloth flowering plants is the perfect shade option for plants like lettuce, spinach, gingers.
Flowers such as salvias geranium lily or camellias have also ideal growth at 40-60% density percentage shade cloth.
If you’re growing in a greenhouse or indoors, you can use this shade cloth to keep your plants cool and protected from harsh sunlight.

75-90% Shade Cloth

Higher percentage shade cloth like 75-90% is for shade-loving plants only. This is the right percentage for such kind of pants.
Plants requiring minimal sunshine do best with high density percentage clothes that provide enough shade for them.
Fern, impatien, lobelia, and orchids are some species of shade-loving plants.

So, the best plan is to choose the right percentage for the plants you grow.

The table below provides recommended shading ratios for various types of shade cloth.
These ratios are based on the different percentages of visible light that each type of shade cloth allows through, as well as its level of blockage against ultraviolet rays.

ShadingName of Plants
30%Roses, Strawberries, Gooseberries, Tomatoes, Cucumber, Peppers
40%Bedding Plants, Gloxinias, Herbs, Iris, Lilies
50%Foliage plants, Cut greens, Orchids, Ginger, Pot plants
60%Orchids ( Oncidiums, Phalaenopsis ), Lettuces
70%Ferns, Orchids ( Cypripediums), Philodendrons, Succulents
80% Certain Orchids, Plantation crops, Tea, Coffee, Cardamom
90%Cattle shed, Poultry houses, Construction Scaffolding, and vehicular shades

Important Reminder:

The choice of a shade net’s shading rate should factor in local weather and temperature, as they directly impact plant health and productivity.

For instance, while a 40% shading rate is typically ideal for tomatoes, in areas of extreme heat like those with highs of 45 degrees Celsius, it might be necessary to increase the rate to 50% or 60%.
Excessive sunlight in these temperatures can stress tomato plants, affecting their growth and yield. Other factors, like soil moisture, ventilation, and the variety of tomatoes, also play a role.

Small-scale testing is recommended to find the best shading rate for each unique situation.

What is the Fabric material of the shade cloth?

The materials used to make shade cloth are generally divided into two kinds.

Most shade cloths are made of high-density polyethylene monofilament or tape.
This product has lightweight properties that will withstand normal wear and tear.
To resist aging caused by solar radiation, UV stabilizers are usually added to the shade mesh.

Another kind of material is aluminum foil shade cloth.
This material has the benefits of a light diffuse effect and high shade effect, which make it popular in the market.

Aluminet Shade Cloth vs. HDPE Shade Cloth

Aluminet shade cloth is made from a polyethylene monofilament frame with woven aluminum foil strips. Aluminet shade net provides good heat insulation and a good reflection effect.
The Aluminet has the strength and durability of polyester and the properties of aluminum foil.

Moreover, aluminet shade cloth has another property HDPE does not have: diffused reflection.

Diffuse reflection is a type of reflection that reflects light in many directions rather than in one direction.
The advantage of diffuse reflection is that it can reflect more light than specular reflection.

Plants depend on sunlight to grow and thrive. But, a plant that other plants surround will not get as much sunlight as one in an open space.

To make up for this, plants use diffuse reflection—bouncing light off of other surfaces—to increase the amount of light they receive. This allows them to grow faster, stronger, and healthier than if they were only receiving direct sunlight.

Thus, this kind of shade cloth is becoming increasingly popular in modern greenhouses.

What is the Method of Weaving shade cloth?

Using shade cloth is important for gardeners and farmers alike. It can be used to protect plants from the harsh sun, as well as to keep them cool in hot weather. Two main weaving types of sun shade cloth are woven and knitted. Each has its own advantages and disadvantages, so it is up to the gardener to decide which one is best for their needs.

Woven sun shade cloth is made using a Sulzer machine, whereas knitted sun shade cloth is made with a Raschel warp knitting machine.

These two kinds of machines weave nets of different structures in different ways, resulting in fabrics with different properties.

Knitted shade cloth vs. Woven shade cloth?

The knitted sun shade cloth is widely used in the market today.

Woven and knitted sun shade cloths have pros and cons, but ultimately, it is up to the gardener to decide which is best for their needs.

Knitted shade cloth is more durable and allows for better ventilation, while woven material (shade cloth) is lighter and offers more privacy.

Effects of color shade cloth on the plants

Using shade fabrics isn’t just about personal preference either… It is widely believed to solve ventilation issues by selecting darker shade cloths that absorb more sunlight. White cloth decreases light but no qualitative light spectrum.

Photoselective nets (color shade cloth) change the light spectrum of transmitted light to influence plant growth.

Therefore plant growth occurs much quicker than using green shade cloths and white shade cloths. The white shade cloth is commonly used for flowering plants. Dark shade cloth absorbs more heat, whereas lighter colors refreeze the sun’s energy. Green shade cloths and black shade cloths generally act as filters and deprive plants of sunlight.

Using color shade cloth on selected plants

Many studies have shown that color-shade cloth can play a photoselective role, and these protective nets can positively affect growth.

The effects of sunshade net on plants can differ from one plant to another. Here are a few examples.


A study by Jorge used four different shade netting colors—black, grey, red shade cloths, and white shade cloth —to shade blueberry plants. The results showed that grey, red, and white nets decreased PARPhotosynthetically active radiation)to different extents. These changes resulted in increased yields of blueberries.
However, there was a decrease in blueberry production when plants were grown under black shade nets.

Cast iron plant

A study from Stamp (2008) showed that the fresh weight of harvested leaves from the variegated cast iron plant (Aspidistra elation ‘Variegata’) was greater under black netting than under blue, gray, or red netting.
The total number of harvestable leaves was greater from plants grown under black than blue or red netting.


In a study published in 2008, Leite investigated the effects of shade nets on flowering and biomass production in Phalaenopsis. He found that the red shade net produced earlier flowering in all cultivars and hybrids except one.
He also found more flowers were produced under the red shade cloth than under the other two nets. Leaf surface area and biomass were greater for plants grown under blue shade nets than those grown under black or red shade cloth.

An experiment used colors blue, grey, pearl, red, and yellow with 30% density and white shade cloth with 12% density in commercial apple and peach orchards.

After one year of research, the result showed the fruit set, fruit size, color, and internal quality all increased.


The researchers studied the effects of shade fabric on spinach grown in a greenhouse. Red, blue, and black shade nets were placed over plants.
At harvest, baby leaf spinach grown under red shade netting had the highest yield. However, dry weight was significantly higher for plants grown under blue shade netting than those grown under red or gray shade cloth.

The results of an experiment showed that 30% pearl, red, aluminized, and blue shade nets can increase the yield of cucumber by 71%, 48%, 46%, and 46%, respectively, compared to black shade cloth.
