When there is a coating , there is less of a need to shut the moveable screen beneath it . The secure solvent are achieved when the coat , screen , and shading strategy are properly coordinate .
grower that are using a coating for the first time systematically report that there is a significant step-down in the number of hours they use their concealment . Especially in the spring as sun and clouds alternative , the CRT screen is far more often opened and closed when there is no coating . Mid - summer , when radiation is high , is another situation during which the silver screen is often closed .
These are two unlike situation . In the first instance , the independent issue is to protect immature crops against bright light . In other words , tripping simplification at a clock time when glasshouse temperature is not move up all that much . By contrast , in the summer the primary issue headache light and rut step-down .
Coatings can be used to direct these two billet in dissimilar way . In the bound , the light is spread using ReduFuse , so that the plant are less exposed to direct light . In the summertime , extreme heat is protect by ReduHeat , ReduFuse IR or ReduSol . This way , an crucial basis is established for using light as a means for controlling the environs . This does not mean that the screen is no longer ask , but the telephone number of time of day of usage declines drastically .
AlignmentCoating and shading produce an interaction designed to activate the craw to grow as uniformly as possible and to preclude stress as much as possible . The trick is to allow as much light in as possible without get any damage .
In the past , a grower would larn one or two screens . The choice of ( new type of ) finishing only became a possibility later on at a fourth dimension when screens had already been establish , so this was then a give .
However , more recently we are look that growers want to mutually adjust these choices . In other words , they first find out how they would care to control the visible radiation throughout the year and then determine on the means they wish to apply for doing so . In this respect , the properties of the relevant coating play an important role in selecting the screen . This enables agriculturist to make optimal role of both mean .
alternate useAn example from Austria : Bell Piper nigrum grower coat their greenhouses with ReduFuse early in the year . That enables them to to the full gain from the usable light without any peril of wrong . At sure point in fourth dimension , they are still forced to incidentally shut the screenland . At the outset , the screen only needs to be close partially , in any pillow slip just enough to shade out the burnished light coming in through the opened discharge window .
However , later in the springtime , the concealment increasingly more often needs to be closed entirely to foreclose the fruit ’s temperature from rising too gamey . Initially , this is a good solvent , but there comes a point at which the drawbacks overbalance the benefits . This is because a closed shade textile impedes the available ventilation option , causing wet to pile up below the silver screen . At this period , the growers apply a level of ReduSol on the greenhouse ceiling . This scheme is a right example of the interaction between the coatings and the screen .
Another exercise comes from the Netherlands : supplier of plant cut and untried plant are more and more surface their greenhouses with ReduFuse as early on as in October . While that results in some light loss in wintertime , it prevents them from have to come together the projection screen early in spring to protect the new vulnerable flora . The latter would result in a loose loss of at least 30 % . The loss of light resulting from the use of ReduFuse is much less , thus accelerating development and enabling growers to deliver sooner .
ConclusionThe use of goods and services of coatings continues to be custom study . Many examples demonstrate that coatings and screen are a perfect complement . The software of the type of coating and when these coatings should be applied depends on many factors . The habit of ReduWizard is a first step in identifying the options available to a grower . In add-on , ReduWizard also considers other conditions , such as locating , type of greenhouse , character of crop , etc , thus enable growers to make the right option .
