Signify has provided Van Wordragen Flowers BV with a full light-emitting diode installation , including a light spectrum with adjustable far - scarlet . This makes the chrysanthemum grower the first in the Netherlands to utilize this technology from Signify . The system , which is set to be launched at the IPM , consists of the Philips GreenPower go toplighting strength with an energy - effective spectrum of blood-red , white , and blue light and , in addition , far - red LEDs which can be steered severally for well elongation . This LED toplighting force-out dynamic was install at Van Wordragen in September 2022 .
Grow lights with adjustable far - red LEDs“Of track , the high push prices were a significant reason for the switch to full light-emitting diode , ” explicate owner Hein van Wordragen . “ What made the difference , as far as I was refer though , was the enquiry by WUR into control elongation and response time with far - crimson twinkle . ” agree to the results , chrysanthemum root word length can be properly determine with full light-emitting diode by allow for subsequent remainder - of - twenty-four hours lighting with 30 minutes of 20 μmol / m²/s far - red light . This research puts an last to the fear amongst chrysanthemum growers that the utilisation of full LED might result in too short prime stems in the winter . Another benefit of using far - red in this way is a potential reduction in the culture period of time by a few days and less shoot growth at the Qaeda of the plant .
“ I had every confidence in the inquiry express out by WUR and finally got in signature with Signify , ” say Van Wordragen . “ They then suggested the Philips GreenPower contribute toplighting force dynamic with adjustable far - red light . ” Leontiene van Genuchten , Plant Specialist at Signify , explain : “ We have already previously trialed adjustable far - red , but at the time , it was mainly about the growth rate alternatively of elongation . This is also because there were still a lot of hybrid inflammation systems at the metre , where elongation was not an issue .
Further researchMeanwhile , further research by WUR has demonstrated that subsequent lighting with far - red also has cocksure effect on craw elongation when illuminated for short periods and using only 10 or even 5 μmol / m²/s far - red . moreover , the hard-nosed software at Van Wordragen next wintertime will give a lot of new information and insights . “ We are all going to study a majuscule plenty , ” enunciate Van Wordragen . “ The issue are highly supporting so far . ” Signify has also been nearly take . Van Genuchten : “ Every calendar week , we reap a modest section to see how long the stalk are . If you then equate this against the amount of far - red applied and the use of plant life growth regulator , it is very enlightening . We want to name when you need far - scarlet in particular and when you might still be able to decrease this ; if you use energy , it require to service a function after all . ”
Pioneering role“My honest-to-god HPS lights were also from Philips , and for such an important step , I do prefer to select trustworthy partners , ” says Van Wordragen to explain his choice of Signify . “ I am the first chrysanthemum grower in the Netherlands to operate on with this Signify solvent , but I did n’t require to feel like a guinea Sus scrofa . ” He does notice his pioneering role in this , however : “ In the chrysanthemum sector , we have a reasonably undefended relationship with one another and deal relevant selective information in terminus of finish . This is something we will also be doing here . It may not be the only solution for safeguard the future of the Dutch gardening sphere in light of current development , but it is undoubtedly a very large and significant first step ! ”
