Getting as much light as possible into the nursery is something growers , and supplier have been mould on for age . Depending on the crop and temperature , a raiser knows how to deploy the perfect mood strategy . The influence of the sunshine make it clear that there is still much to be gained . PHYSEE responds to this with its luminescent finishing applied science . In the audience from InnovationQuarter , Sadiq van Overbeek , Co - founder PAR+ at PHYSEE , discusses the challenge of exploiting the tremendous ( ceiling ) potential difference of the sector .
PHYSEE will apply the finish from July 2022 at Kwekerij van Boxel ( 600 m2 ) and Firma Verkade ( 900 m2 ) on greenhouses with cucumber vine and tomato , severally . PHYSEE , together with the growers , is involved in the validation of the PAR+ coating in cucumber and love apple polish .
The pilot light will then start over a full stop of 40 weeks and will continue until the end of July 2023 . PHYSEE is responsible for supervise the coating quality on the glasshouse roof and the loose spectra under the coated section and the command section . Verkade company and the Van Boxel glasshouse are responsible for weekly monitoring of the crop . The amount of harvested product and various crop characteristic are monitored .
right crop growthThe Delft mellow - tech actor secure more Photosynthetic Active Radiation ( PAR ) in the greenhouse . This part of the light is ask to accomplish photosynthesis for the good growth of the harvest . The PAR+ coat that PHYSEE develops converts harmful ultraviolet illumination light into growth light and also makes the incoming light diffuse . " In nursery gardening , the rule has been in effect for decades : one percent more PAR equals one percentage more production . In recent eld this has become a chip more nuanced and base on which crop . But you see that this applies to many case of crops . consider tomatoes , cucumbers , strawberry , and rose . you may imagine that the raiser in the Netherlands , and countries with similar climates , are doing their utmost to get the light into the greenhouse , " suppose Overbeek .
From permanent to washableThe idea behind the coating technology originated during a cycle subspecies in Westland , a realm in the Netherlands . Many intellection , but this one stuck : what happens to UV brightness in all these glasshouse ? " After a lot of inquiry , Overbeek contact partners in the glass manufacture . The program used there was a permanent coat on new field glass . " In this way , the cultivator does n’t have to be waitress for that . After all , they would have to replace all their glass with that . Our team then looked at existing app methods and adapted our finishing so that it could be integrated into existing infrastructures . Our pill roller played an authoritative role in that . " The renewed ( washable ) coating , which convert ultraviolet radiation therapy into PAR light , retains its effect for a period of 8 years and can continue on an live glasshouse cover all yr round .
