"Double layer roof shade nets are a unique design for climate-sensitive crops such as bell pepper", the team with Indian nethouse supplier AATRE Green says. "The freely ventilated structure is built to naturally regulate temperature and relative humidity to optimum levels." In a video, they show how their project in Tenpur, Gujarat is equipped with a double roof shade net.
They say that premium fruit shape is important for a premium price. "And fruit sets can be malformed when the temperature is high. With the double layer retractable inner net, you can easily control how much light reaches the plant."
The first layer has a light permittivity of 10-12% while the inner layer has 30-50%. With this, long sunshine hours in summer can be checked.
Another useful advantage of a double-layer net house to bell pepper is preventing sunburn. "The interaction of high temperature and light will scald your precious fruits, damaging them completely. For higher sunshine days in summer, the second layer can shade the crop and retract in the evenings when temperature is low. By doing this you can have total control of your valuable crops against hazardous weather conditions. This is what shade nets can do."
