The answer to hot summer : a coating as the foundation , if necessary an extra layer in mid - summertime and eliminate light peaks with moveable screen .
After two red-hot ironical summer , agriculturalist have started to think differently about how to protect their crops , observes Account Manager Jelle Hoogland who apprise greenhouse agriculturalist in westerly and Central Europe . “ There is no doubtfulness we ’ll be have more of these hot summers . It is therefore advisable to give heedful thought to your scheme . Make maximum use of any available luminousness when possible ; protect your crop when necessary , ” he says .
This strategy is founded on a coating that is applied in the spring . “ Growers are increasingly opting for ReduFuse or ReduFuse IR to effectively spread the light within the crop in the outpouring . That provide for extra ontogenesis , product and quality , ” he say .
transportable screen settingsIf there are high solar radiation peaks during a geological period of luminosity , they can be attenuate with transferrable screen . “ Growers on a regular basis involve us motion about combining coating with moveable screens . The basic assumption is that the screen setting in the climate control computer must be adjusted . For exemplar , if the screens primitively closed at a solar radioactivity of 700 watts , then this mount must now be increased , ” he says .
This is necessary because the sluttish metre is locate outside the glasshouse as part of the climate control computer ’s atmospheric condition post . When a coating is hold , less light will enter the greenhouse . Furthermore , ReduFuse and ReduFuse IR better pass around the brightness within the crop which would grant high radiation levels in the glasshouse anyway .
In world , it would be estimable to measure the light at heart rather than outside the greenhouse to make an effectively order surroundings inside the greenhouse . This concept is gaining dry land , albeit very slowly . In part because the measure technique used inside the greenhouse have not yet been perfected .
Keeping the passion out“A coating keeps the supernumerary ignitor and heat outside the greenhouse . With moveable blending , this energy still gets into the greenhouse . While it may accumulate above the closed screens , the vim nevertheless drops down . In addition , when the blending is shut down 100 % , the greenhouse becomes too hot . When you partly open it , part of the plants end up fully exposed to the sun , ” he tell .
Growers of light - loving crops in Western Europe for the longest clock time relied on transportable shading to egest light peaks . In late class , even this class of agriculturalist has also opted for coating such as ReduFuse and ReduFuse IR . “ The coating provides the canonical protection ; the screen are the parking brake brake , ” says Hoogland .
Climate changeIn a continental climate , such as Central Europe , this is not enough . The strategy here is as follows : a diffuse coating is applied early on in the yr , abstemious peaks are eliminated with a shade silver screen ( if available ) and additional ReduSol or Spray Chalk is go for in mid - summer . This take a leak it potential to effectively forebode hard fate that due to climate alteration are anticipate to come more oftentimes .
Vent windowpane settingsHoogland propose that you should not only change the computer mount for the moveable blending when a coat has been applied to the greenhouse cover . “ The venting preferences must also be vary . When ReduFuse is used , the windows should not be set across-the-board opened . Because this will produce spots throughout the greenhouse where the crop is full exposed to sunlight . The trick , in that case , is to open up more of the windows on the wind side , alternatively of on the lee side . This will provide for a sufficient gentle wind circulation with a smaller windowpane opening and the area let on to the sun ’s full radiation , therefore , persist modified . Another advantage of a smaller window opening is that it more efficaciously keeps the CO2 inside , ” he concludes .
