Midstream bespoke light spectrum solution
As well as looking to reduce the amount of power consumed when growing its roses, Dorors had another good reason to explore an alternative lighting solution: quality.
The market value of a rose is dependent on many things, but the length of the stem and the quality of the petals have a major impact on the price of a flower. With that in mind, Dorors was also keen to see how a different spectrum of light might be able to improve the quality of its roses. Here, Midstream’s technical capabilities came to the fore.
Using its Flare luminaires as the basis, the Midstream team created “SFLO” – a customised spectrum optimised to the needs of a germinating rose. Combining high amounts of photo- and far-red light, this spectrum was used to create a tailored LED board, one of which was fitted in each of the 165 Flare units installed at Dorors’ facility. At a height of two metres above the grow area, the luminaires delivered an average of 159 μmol/m2/s.
In order to test the effectiveness of this bespoke solution, Dorors implemented a hybrid installation that replaced 50% of the HPS lamps in one of its greenhouses with the Midstream Flares. With the remaining HPS lamps retained primarily for heat purposes, the Flares helped to drive a 40% reduction in power consumption – while also delivering significant improvements to the length of the flowers’ stems.
