At the end of February , two types of lamp were shining at the forefront of the glasshouse at GreenDreamz : HPS and LED . Grower Wouter Vreugdenhil use them for the propagation stage of his Cannas . This propagation takes position in three compartments that are enclosed with plastic sheeting . This winter , for the first time , the agriculturist also coif up a compartment exclusively with light-emitting diode inflammation . He is pleased with the results . Next winter , he plans to hang LED lamps in the remaining two compartment as well .

Energy SavingBut by the end of February , that sentence has not yet come up . " First , I need to take in a bit of money , " laughs the cultivator , who , like many growers , has had unmanageable years with rising Department of Energy costs . The three - hectare nursery full of Cannas , various green houseplants , and also bed plants in the springtime , is heated with a steam boiler . With all the coming revenue enhancement measures and the recent spikes in gas cost in mind , any horticulture partizan understands that it has not been gentle at ' t Louwtje in ’s - Gravenzande .

" Compared to 2019 , when we commence with Cannas , we have reduced our petrol consumption by a third , " share Wouter while pointing to the bubble wrap along the glasshouse frontage . " We also put on lessons from Het Nieuwe Telen ( The New Cultivation ) . To get rid of wet , we on occasion open up a gap , but no longer 20 % , but a maximum of 4 % . That turns out to be enough to get rid of the moisture . In add-on , we have invested in an energy drape and a DryGair unit . "

Propagation Space CreatedThe agriculturist wants to continue focalize on timber in his cultivation but also on energy saving . By improving the extension form , he hit two birds with one stone . To improve the propagation phase angle , he initially considered converting his cold room into a propagation space . This would require building a multi - layer system that would also need LED inflammation .

For GreenDreamz , this prove to be a bridge circuit too far . Financially , the raiser could not make it work . Hence , a part of the glasshouse now serves as a propagation blank . The Cannas grow there are in new plugs from Quick Plug . " With this , we ’ve already made a substantial betterment . The plug now takes source after just one week . antecedently , this sometimes took up to four weeks . "

More Uniform Light DistributionHe is also proud of with the light-emitting diode lamps . " Rooting under light-emitting diode die well , I have had little loss this winter , and moreover , my DOE phthisis is lower . " The light-emitting diode lamps hanging in one of the three compartment are supplied by AGROLED . Together with Mark van der Ende from the troupe in Kwintsheul , Wouter consider out the current generation setup under LED . Mark : " I challenge cultivator to think differently . So , not always more Inner Light in the nursery , but calculate at what the plant require . Enough is enough . "

The reparation hanging above the plug plants has a business leader of 150 watts . It is a notably little mending . Wouter take the air into the LED compartment . He pulls out his earpiece . " Look , " he shows , " with this light valuate app , you may see that I now have a much more undifferentiated light dispersion . " Compared to the mensuration in the middle aisle in the HPS compartment , the difference is indeed significant . The light intensity on the middle aisle is doubly as low as in the LED subdivision . " The light-emitting diode fixtures have a beam of light angle of 120 level , " Mark excuse .

Extra HeatThis is an Italian - made fixture from the Combo serial from C - LED . AGROLED is the distributor of the lamps in the Netherlands . Another test with a smartphone follows . " On your phone ’s screen , you could see what the spectrum is , " Mark shows . " It ’s spring ignitor . "

After a winter , Wouter sees no notable calibre difference between the compartment with only HPS and those with only LED . He is satisfied with that . " Where necessary , we sometimes use two effulgent warmer in the light-emitting diode department for some extra hotness during the rooting form . For this , we take temperatures between 20 and 22 arcdegree Celsius . Afterward , 18 degree Celsius is a fine temperature that we also reach well with only the LED lamps . "

Opportunities in Colder CultivationsFor the coming winter , Wouter has already instructed his controller to utilise for an SDE subsidy , which will partly ante up for his new light-emitting diode lamp . After delivery , it ’s just a topic of fire hydrant - and - play installation . " Our lamp can just be link up to 400 volts on the existing wiring , " Mark indicates . He sees opportunity in quite a few colder cultivation for the solution that Wouter also chose . " Many grower only illuminate for a few months of the year . Here ’s my advice : Think about whether it can be done more economically with less light . Moreover , you spare on your investment toll compare to a secureness with a high force . "

Shortly after our sojourn , Wouter turns off the lamps . The generation season with the light-emitting diode lamps guide from mid - September to mid - March . " Outside the lighting season , the advantage is that the precede fixing is so compact . This allows more instinctive light to recruit . "
