Greenhouses, as well as small and large tunnels, provides an ideal microclimate around the plants. Greenhouses protect the plants from the adverse climatic conditions such as wind, frost, cold, rain, precipitation, excessive radiation, extreme temperature, insects, and diseases. It provides an ideal microclimate around the plants.
Greenhouses help fruit, vegetables, and flowers to ripen faster, allowing several crops to be harvested in one year. Moreover, a modern plastic film can be tailored specifically to the unique light and temperature requirements of many field-grown fruits and vegetables. At the same time, the plastic film helps to reduce water consumption by reducing evaporation.
Greenhouse films retain daylight heat and thus keep the temperature in the greenhouse higher than the ambient temperature during the night.
In greenhouses with UV Polyethylene Film, the plants grow more uniformly and with more vigor and are less susceptible to disease with richer colors in their blossoms and leaves. It also increases the productivity of fruits, flowers, vegetables, medicinal plants, tissue culture etc. by reducing the diseases and pests.
Due to degradation processes induced by sunlight and heat the life of polyethylene film is limited. Film polymers deteriorate rapidly when exposed to sunlight. The sun’s ultraviolet (UV) light transfers its energy to the polyethylene molecules causing them to become so energized that they are readily subject to oxidation.
Biggest greenhouse film manufacturers do stabilize their film against degradation due to solar radiation. Also, Averto greenhouses are covered with transparent or translucent U.V stabilized film large enough to grow crops under partial or fully controlled environmental conditions to get optimum growth and productivity.
The UV stabilizing additives in the greenhouse films capture sunlight as well and achieve light and heat diffusion within the greenhouse for uniform plant growth. They also protect plants and especially flowers by filtering out UVA and UVB radiation, and by limiting part of the solar spectrum that favors insect development.
