3 Key Factors to Keep in Mind When Selecting the Ideal Shade net for Greenhouses

Understanding the main types of shade cloth materials used in greenhouses is important, but choosing the right one can be challenging. To make an informed decision, focus on three critical factors: shading percentage, cooling efficiency, and durability.

1. Shading Rate
To determine the appropriate shading rate for a Shade Net, consider the greenhouse structure, covering materials, local climate, and crop types. Keep in mind that light requirements vary among crops, and each has unique light compensation and saturation points throughout their growth stages. For instance, fungi (such as shiitake, oyster, and enoki mushrooms) require more shading than vegetables like spinach and lettuce.

By evaluating multiple factors, you can identify the most suitable light intensity for your crop and select the most cost-effective and appropriate Light-Blockage Net .

2. Cooling Efficiency
The shade net`s cooling efficiency improves as it reflects more solar radiation while still meeting the crop`s light requirements.

For an Inner Sunshade Series, part of the reflected solar radiation is absorbed by the shade net, raising its temperature and increasing the greenhouse`s temperature through heat exchange with indoor air. To optimize indoor cooling efficiency, choose a shade net with high solar radiation reflectivity. Aluminet nets, for example, offer significantly better cooling efficiency than other types due to their higher reflectivity. Consider aluminet nets for indoor shading purposes.

For external shading systems, the cooling efficiency mainly depends on the shading rate, as the energy absorbed by the shade net itself can be disregarded.

3. Durability
A shade net`s durability is influenced by factors both inside and outside the greenhouse, including climate, temperature, ultraviolet (UV) rays, and chemicals. These elements can impact the shade net`s lifespan.

Indoor shade cloths are protected from harsh weather conditions such as wind, rain, snow, and hail, resulting in a longer lifespan compared to external ones. However, the chemicals used in greenhouses, like insecticides, fertilizers, and pesticides, can react with the UV stabilizers in the shade net`s UV layer, reducing their effectiveness. Avoid letting chemicals come into contact with indoor shade cloths.

Outdoor shade cloths are exposed to more UV rays and harsh weather conditions like wind, rain, snow, and hail. When choosing an outdoor shade cloth, consider the shade net`s strength, heat resistance, and UV resistance.
