Transport and storage
» While transporting and storing the bobbins, these must be laid on an even surface with no sharp or projected ends that could damage them.
» Heavy or sharp objects (wire bobbins, sticks, etc.) should not be placed on top of the bobbins.
» Do not drag the bobbins when transporting and/or installing, neither scratch nor scrape its ends against objects.
» To store the remaining bobbins, we recommend you use a cool and dry place, wrap them in opaque plastic material.
Installation
» During the installation process, we recommend you regularly check the greenhouse structure by making sure that there is no rust and are no loose ends or wires.
» Do not drag or scratch the bobbins during installation.
» The sheeting must have a suitable stress, therefore, we suggest not installing it during the hours of intense heat, because it may lead to softening of plastic which can cause excessive placement stress and provoke severe material contractions
» Do not tighten after tapping.
» Prevent any direct sheeting contact with the structure and, in these areas, use adhesive reflective tape or light-coloured water-based paint to avoid breakage due to high temperatures.
» In tunnel and multi-tunnel type greenhouses, the aforementioned recommendation is essential as the tubes will be in contact with plastic.
» If you carry out whitening of plastics during the high radiation period, we recommend you use suitable products that do not affect the plastic’s lifespan. And for cleaning, you must use water-based products with no acid components.
Use of agrochemicals
» The use of Plant-protection products can release compounds that affect the effectiveness of stabilisers against UV radiation.
Therefore:
» You must comply with the recommended dosage and treatment intervals, limiting the use of pesticides to a minimum, particularly those with sulphur and / or chlorine in their composition.
» Apply the product on the crop and not on the plastic. Avoid accumulation of pesticides at contact points between plastic and structure.
» Ventilate the greenhouse as quickly as possible.
» If chemical disinfection of the soil is carried out, it is vital to cover the soil with plastic sheets with barrier properties that prevent the disinfectant from attacking the plastic covering and, once the disinfection plastic has been removed, ventilate the greenhouse well.
Pollinators
» All newly installed greenhouse cover plastics have very strong absorptions from the ultraviolet radiation they receive from the sun to ensure their durability. This can cause some initial disorientation of the pollinators, which is resolved once the insect gets used to the environment and / or after that initial period
» Help the pollinator adapt as quickly as possible to the new environment when the cover film is new, there are certain techniques such as:
- Carry out slight whitening of the cover if it has a lot of direct light (high transparency).
- Try to lower the greenhouse temperature by ventilating until you get close to the optimal pollination parameters.
- An increase in population (greater number of hives per zone) may correct initial deficiencies in pollination, if any.
