We use net shades with a density of 10% to 30% when establishing net houses in orchards, mainly for the prevention of ravages and sun damage during the ripening and flowering period. During these periods, these trees are sensitive and there is the risk of significant damage of productivity, as a result of extreme weather conditions. The net house prevents the occurrence of these hazards and saves trees. The net houses in the orchards are of a unique construction, that enable the fold of the nets during the winter and their deployment during summer, as required. Automated systems can also be integrated for deployment and folding.
