In 2018 and 2019, I tested different colors of shade cloth for green bell pepper production on drip irrigated black plastic mulch. In those trials, the 30% black shade cloth treatment produced the highest yields and increased marketable yield to three times the marketable yield of no shade cloth (Fig. 1).
What Colour shade cloth is best for vegetables?
Green knitted shade cloths with a 30% density is ideal for a vegetable garden. Letting in an ample amount of light and heat to promote vegetable growth.
What color shade cloth should I use?
White shade cloths are often used for flowering plants. Dark colour shade cloth is known to absorb the sun’s heat while the light colours reflect the sun’s heat. Usually, green and black shade cloths behave like filters and deprive the plants in receiving much sunlight.
Is green or black shade cloth better?
Dark vs Light Color
The argument is if you are looking for maximum cooling and UV protection a dark-colored shade will be the best option. Dark colors like our navy blue, black or brown, will absorb more UV rays, thus making the area underneath the shade cooler.
Is black shade cloth hotter?
Black and green shade cloths absorb heat and protect from harmful UV rays, and filter light. White shade cloth reflects heat and diffuses UV rays. It reduces the amount of light getting through while not affecting the quality of the light spectrum. It also lowers greenhouse temperatures while black increases them.
What is the best color for a sunshade?
The Cancer Council in Australia suggests that darker colors absorb UV rays, which helps block them from your skin. That’s why dark blue, black, and dark red are the best colors for sun protection compared to white or pastel colors of the same fabric.

For example, 40-50% shade cloth used in a high tunnel or greenhouse with good ventilation and air flow can easily lower temperatures inside by at least 10°F (5.5°C) and possibly more than 15°F (8.3°C). That means if it’s 95°F (35°C) outside, it could be as low as 80°F (26.6°C) inside.
Are light or dark sun shades better?
In terms of thermal performance, lighter colors have higher reflectivity values and therefore reflect more thermal energy out of the room. Darker colors have lower reflectivity and higher absorption and as a result transfer more heat into a room.
What color shade cloth is best for tomatoes?
White and aluminet shade cloth options are quickly becoming favorites for tomato producers. The reason for this is the additional heat they tend to keep off the structures.
Does white shade cloth reduce heat?
White shade cloth offers reduced heat build up thanks to reflection of the sun’s powerful radiation. Diffusion of light underneath white shade cloth is also improved. Use for flowering plants which will be effected by longer natural light exposure due to an increase in light quantity and duration.
Does shade cloth reduce heat?
Shade fabric is a knit or woven fabric designed to reduce the amount of solar heat that reaches plants. With the invention of shade cloth, gardeners can now control the heat and light that their plants to be exposed to.

How much can shade reduce temperature?
Incorporating shade from landscaping elements can help reduce this solar heat gain. Shading and evapotranspiration (the process by which a plant actively moves and releases water vapor) from trees can reduce surrounding air temperatures as much as 6° F.
Does the color of a sun shade matter?
For instance, many darker shades block out more UV rays, making them a natural choice for warmer and sunnier areas of the country. Lighter colors, in general, allow more of the sun’s rays to pass through, which may be important if you have grass or plants growing under your shade.

What percent shade cloth should I use?
Usually a shade percentage of 30-50% is ideal for vegetables, while 80-90% is ideal for sheltering people. Most plants will do best with a maximum of 40% – 60% shade. However, when growing some shade loving plants such as orchids and some ferns, 75% or higher maybe needed to get correct light levels.
Can you double up shade cloth?
Many successful growers are using a double layer system of shade cloth.
