There is a lot of movement in the greenhouse light market place at the moment . Over the add up two months , glasshouse veggie agriculturalist in Northwest Europe will for sure have to make decisions . And also in floriculture grower are faced with choices . Do they want to use ( more ) artificial light ? And if so , with which fixtures above the crop ? With what spectrum ? With which installation ? And how to deal with the muscularity part ?
Looije Agro Technics supports growers as an self-governing consultancy bureau with these issues and , in a series of four article , examines these questions from unlike angle and strategy and more . Today part 3 on the grandness of go on to measure .
speedy developmentsLED fastness are in uninterrupted growing . Fixtures increase in efficiency every year and provider come and go . For us , as an independent consultancy , it is of the utmost grandness to have the right principle . Where potential , we measure production fixtures ourselves in a lab apparatus to make it at a digital 3D model . Under science laboratory conditions we can dominate out any form of outside influence .
Besides measuring the turnout , we also reckon at the input . How does a fixture react when switching on and off and does the state consumption correspond with practice . The results of the lab measurements form the foundation for forecast various scenarios .
An example of a kindling plan in which dissimilar regular hanging along the façade are compare
1 - to-1 comparisonBased on spectrum and output , we select dissimilar fixture together with the raiser that are placed next to each other in a ( 3D ) lighting program . By making the firing plans ourselves , we forfend witting or subconscious ignorance and juggling with number . With us there are no hidden parameters or vary modeling , only a 1 - on-1 comparison . We are main and use various HPS or LED fixedness or a combining of both , also from different suppliers . The different scenario are created with different habitue for the raiser - specific position .
An example of a 3D lighting plan . Uniformity is of great importance .
possibility is fun , practice countsFor us , a field measure of the output of the fixtures in the greenhouse is part of the total conception in disburden . After a successful installation , it is significant that the modeled output is at least equaled , after all , a flora is always fair . Inequality in the light mental image will always be seen in the cultivation . It calculate on the harvest to what tier inequality is accept . In add-on , it is significant not only to measure the output , but also the input signal . ignition is about the correct conversion of electrical energy into visible radiation .
Data = powerOur advice is to keep supervise the input side of the inflammation . Deviations can be supervise and registered by means of a power analyzer . This monitoring can even take place remotely . In addition , it is advisable to reprise a field measurement frequently in orderliness to be able to determine any red ink in output in time . give the gravid total of the investments , it is important to know what happens during the operating hours in ordering to be able-bodied to make a sustain warranty claim .
Looije Agro Technics would like to bridge the gap between theory and practice . " By mean value of our own knowledge and experiences in practice session , the plain and laboratory , we are capable to translate the lighting pauperism of the grower into unbleached advice with a mark - independent view .
