Film lifetime is guaranteed for a period of 1-5 seasons (depending on type of film and area of use). In most cases, greenhouse films contain more and more efficient UV-stabilisers than films of other producers, which is one of the reasons why PEP films usually last longer than they are prescribed for.
Due to the increasing use of sulphur and other chemicals in the greenhouses, that neutralize traditional UV-stabilizers and may lead to premature failure of the film, HiTeC has developed fully chemical resistant formulations that can be incorporated upon demand in any of its greenhouse film types for additional safety.
The advantages of thermic films are:
- Protection from frost and low temperature.
- Smoother temperature drop.
- Overall higher night temperatures.
- Reduced energy consumption for heating.
- Higher crop yield.
- Earlier harvesting.
- Better quality of crops.
It is now generally accepted that diffused light has a positive effect on plant growth, especially for spring and summer crops and in areas with many days of strong, direct sunlight during the year. Light diffusion offers a moderate cooling effect, it prevents burnings, it reduces shadows and ensures more uniform distribution of light, so that it reaches even the lower parts of plants.
HiTec has the know-how and therefore the ability to produce:
- Crystal clear films with very low diffusion (Maximum direct light).
- Films with medium diffusion
- Films with very high diffusion
The choice of the most appropriate level of diffusion depends on the climate of the area, the crop and the season(s) of growing. HiTeC’s experts are at the disposal of our customers to consult them on the most suitable level for every particular case.
HiTeC manufactures “anti-dripping” films that contain special additives which eliminate individual droplets, turning them instead into a continuous thin layer of water that runs down the sides of the greenhouse roof and walls.
Anti-dripping films, when used properly, offer the following benefits:
- More light in the greenhouse
- Higher crop yield
- Earlier harvesting
- Better quality of crop, higher commercial value
- Fewer diseases
Reduced need for pesticides
Important types of disease and insect control films are UVblocking films, that absorb UV-radiation up to 380nm, thus achieving:
- Reduction of the population of whiteflies, thrips, miners, aphids and other harmful insects.Reduction of such populations also results to reduction of viruses which can be vectored to cultivars by these insects.
- Control of the spread of certain diseases, by reduction of the sporulation of the relevant pathogenic fungi.(Example: Botrytis)
- Reduction of “petal blackening” of red roses, which actually results in increasing their commercial value.
