JH Hortitech adopts advanced sewing technique to process insect net into accordion shape which is called accordion insect net or window insect net. The material is different from normal anti-insect net. It can reach perfect performance against various insects while actually will affect the window ventilation as little as possible. The airflow in the greenhouse becomes more constant because the netting breaks up the wind, and the plants will move less. The netting keeps rain out so you can ventilate for longer. Light is essential. Our quality accordion insect net ensures the light intensity remains at a maximum in the greenhouse.
