In this article, we will discuss in brief about greenhouse films. We will try to answer some regular question about benefits, types, and applications of agricultural greenhouse film, as well as their impact on the environment.
• Clear – very less diffusion (below 20%) • Clear Plus – Less diffusion (30-40%) • Diffused -Medium diffusion (60-70%) • Cool – high diffusion (80-85%) These are speciality greenhouse films • Rosa - UV Blocking films for rose cultivation. • Chroma - UV open films for bi colour rose fruits etc. • Anthura - 15 to 70 % shade (hot area / Nursery / Anthurium/ potted plants) • Eclipse – Darkening / Black out films (panda films) Black & White or Black • Grifa -special films for cannabis cultivation • Photo selective Blue - special films for vegetables, fruits and seedling
• Films should have high light transmission and optimum diffusion properties • UV, IR, and Thermal stability • Anti-dust properties to keep clean • Anti-drip / fog reduction properties for protection from diseases • UV blocking and Anti-virus effect • IR reaction helps in temperature reduction • IR thermic helps to trap heat inside the greenhouse • Anti-Sulphur / Chlorine properties provide protection against pesticides • Excellent Mechanical strength, tear resistance, flex crack & ESCR increase the life of the film • Reduction of viral and fungal attacks • Reduction of water usage • Protection from biotic and abiotic stress • Reduction of pest attacks
Climate control: Greenhouse films are able to create climate for plant growth throughout the year, with regulated temperatures, humidity, and light exposure. Protection from weather elements: Protection from difficult weather conditions, such as wind, rain, and hail is another point. Frost damage can be controlled by it. Pest control: Greenhouse films make a barrier to pests, such as insects and rodents, by using no pesticides. Water conservation: As it prevents direct interaction of sunlight with soil, water evaporation decreases. It makes possible less water and more irrigation. Energy efficiency: Greenhouse films require less energy to heat and cool than traditional buildings, as they are smaller and have better insulation. Applications of Greenhouse Films Greenhouse films are used in a variety of applications, including: • Commercial agriculture: Greenhouse films are commonly used in commercial agriculture to grow a variety of crops, including fruits, vegetables, and flowers. They provide an ideal growing environment and help to increase crop yields. • Research and experimentation: Greenhouse films are used in research and experimentation to study the effects of different growing conditions on plant growth. This allows scientists to develop new crop varieties and improve agricultural practices. • Home gardening: Greenhouse films are also used by home gardeners to extend the growing season and grow crops that are not typically grown in their region. They are also ideal for growing plants that require specific growing conditions, such as tropical plants. Greenhouse films have revolutionized agriculture by providing a controlled environment for the growth of plants. They offer several benefits, including climate control, protection from weather elements, pest control, water conservation, and energy efficiency. However, their production, use, and disposal have a significant impact on the environment, contributing to greenhouse gas emissions, plastic pollution, and resource depletion. To minimize the environmental impact of greenhouse films, farmers can use renewable energy, choose eco-friendly films, reduce waste, and improve efficiency. In the future, advancements in technology, sustainability concerns, and changing consumer demands are likely to shape the future of greenhouse films. As we continue to develop new and innovative solutions for agriculture, it will be important to consider the environmental impact of greenhouse films and take steps to reduce their footprint on the planet’s
