In instance outside temperatures are lower than inside the greenhouse , while at the same time humidity level are high , open up the windows will not necessarily have the correct effect . Even though real temperature levels might go down , humidity grade and therefore the amount of zip in the air , the so - call enthalpy level , might nevertheless increase . Put simply : very humid conditions combined with temperate temperatures might be less pleasant than conditions hotter but less humid . This go for multitude and plant .
By agency of smoke , the workings of Nivolution combined with Nivolators is instance .
This myopic theoretic introduction is necessary to infer the workings of Nivolution , a dehumidify system developed by Nivola . Nivolution blows cold , ironical airwave from above the greenhouse screen down , thereby intermingling with the warmer , more humid air below . Thus the greenhouse is chill and dehumidify in an energy - efficient manner .
Yesterday , Nivola , the caller which spring up the Nivolution and Nivolator , invite a few growers and technical installation companies work with Nivola for a short seminar presenting a exam project at Dutch genus Gerbera growerKwekerij Antonia . Together with the cultivator Frans Mans , research specializer Peter van Weel ( also known for his involvement with thePlant Empowermentproject ) , remonstrate those present on establishing a respectable , homogeneous , lively glasshouse mood .
In burden a grower desire to keep the most optimal growing conditions . In doing so , he need to cope with ever - changing weather circumstances , while at the same clip endeavor to be as cost - efficient as possible . A perilous balance , but to some extent knowledge of the agency energy is preserved can help . get-up-and-go expiration , Van Weel explain , either blown out the windowpane ( literally ) , radiate through the glass , or is suffer when ( taste to ) getting rid of humidness . The first two can be countered by closing window and screens , the latter by drive ascendancy of evaporation .
Crops call for to evaporate water , for if they do n’t , plants will be less resilient while also botrytis and mold settle in more easy . Therefore incessantly guaranteeing condition in which crops can vaporize water is crucial . have it off both temperature and relative humidness , both inside and outside , should make a agriculturalist focal point on absolute humidity levels . Absolute Humidity , Van Weel stressed , ought to be one of the most crucial parametric quantity any grower should see to .
Nivolution is already usable at different cannabis agriculturist in both Canada and Portugal . In The Netherlands , a handful of growers is couch it to the tryout . Grower Frans Mans is one of them , trail the Nivolution in combination with the vertical van call Nivolators . Results can be confer on request , for now , it will suffice to say the grower himself is happy . He ’s hardly seen any botrytis and no mildew since , and also temperature differences within the greenhouse are greatly reduce . One matter to be ameliorate business concern tuning it to all the other configurations within the mood computer , an assignment no doubt the dissimilar producer have taken note of .
