Advantages of a Greenhouse Net

greenhouse net

A greenhouse net is an important tool for the protection of your plants. These are manufactured from 100% virgin HDPE and offer shading levels from twenty to ninety percent. In addition to providing shade, they also help reduce heat load in a greenhouse. Several advantages of greenhouse nets are listed below. If you are interested in buying one, you can do so at factory prices from China. Read on to find out more. Let us know what you think!

Knitted nets are made of 100% virgin HDPE

These knitted greenhouse nets are made of 100% virgin polyethylene (HDPE). They come in different colors such as black, green, and blue, and have a shade rate of up to 95%. They are UV stabilized and come in flat filament or round filament types. Their shade rate is based on the density of the material, and you can choose from a variety of different shades for your plants.

This plastic net is used as a greenhouse shade, frost protection, and pest control. It is a lightweight, rot-resistant, and UV stabilized material. It can also help keep soil moisture in, protecting plants from harsh sunlight and birds. Besides, the net is easily laid, either manually or mechanically. Most products can be ordered in lengths up to 50 feet, and you can fold them for easy storage.

They protect plants from insects

Aside from protecting your plants from the harsh elements, greenhouse nets are also useful for other purposes. They can be used to cover windows and doors to provide additional ventilation and protection from insects. Aside from protecting plants from insects, shade cloth also prevents damage caused by intense sunlight. A shade cloth can keep plants cooler during hot days and filter up to 90% of sunlight. There are several types of insect netting to choose from.

The smallest sized meshes are not effective enough to completely keep out some beneficial insects, and some species may be excluded. Nevertheless, Bell and Baker showed that pore size does not always correlate with insect migration. Insects with small thoracic width can intrude a net with the smallest pore size. Therefore, netting with a small mesh size can still be effective.

However, pesticides do not always protect plants. Operators must know how to apply the pesticide to protect their crops. Not only should the right pesticide be applied at the right time, but it should be aimed at the specific type of pest. Insecticides may not be able to penetrate dense foliage. If the plant canopy is full of older leaves, removing these leaves can increase the coverage of the spray. A greenhouse net may require multiple applications of insecticide to reach all of the leaf surfaces.

Those looking to protect their crops from insects should be aware of the slug and aphid pests. Aphids are wingless, fleshy creatures that feed on plant sap. They produce a sticky substance called honeydew, which is eaten by ants. The slugs often infest any part of a plant, including the roots. They also tend to be associated with ants.

Insect netting can be purchased in various sizes to fit your needs. The Garden Tailor insect mesh fabric is lightweight and folds flat for storage. Made of high-quality polyethylene and nylon, it is durable and resistant to insects while keeping out water and sunlight. Insect netting also provides protection against deer, rodents, and other undesirable creatures. The netting also prevents excessive weather, which can affect the growth of plants.

They reduce heat load in greenhouses

The three ways to lose heat from greenhouses vary, but there are several basic methods that greenhouse growers can employ to reduce the loss of heat. One of these methods is insulating the greenhouse floor and walls. This can improve the greenhouse’s U-value, which measures how much heat it absorbs and transfers. However, one of the main problems with insulating greenhouse floors is that it limits the amount of indirect light that can reach the plants.

In order to improve air circulation in a greenhouse, use fans that move air in a horizontal direction. Horizontal air flow fans, which can be 12″ to 20″ in diameter, should be placed forty to fifty feet apart. When operating, the fans should move about 60 to 70 percent of the rated air flow. The added benefit of air flow fans is that they help reduce disease pressure by reducing moisture on the surface of leaves and increase carbon dioxide levels next to leaves.

Increasing the use of thermal screens will prevent excessive heat loss through the greenhouse roof. By using two or three thermal screens, growers can effectively reduce the amount of heat they lose through indirect heat transfer. To further minimize heat loss, growers should fix any leaks in their greenhouse cover. Look for small holes near entryways, corners, and where the cover meets the ground. These gaps can allow air to escape if the greenhouse cover is not sealed tightly. By reducing the amount of heat loss in greenhouses, growers can save money on heating costs.

Another method is limiting incident solar radiation. While this method is effective for moderate climates, it is not efficient in warmer ambient temperatures. Furthermore, limiting incoming sunlight is ineffective in greenhouses with high U-values. In addition, the walls of greenhouses are conductive and can be subjected to overheating, leading to wasted energy. The solution is to control greenhouse temperatures according to the type of crop being grown.
