Signify has help Topline Gerbera nursery in its passage from HPS to full LED . " The flower character is fantabulous , and the production can credibly even be increased a bit , " raiser Rino Mans enunciate sky-high .
Mans has been following maturation in light-emitting diode lighting for gerbera for several years . Last yr he decided it was time to take the first measure . " vigor prices were rising , and it was decipherable that we could n’t go optimally with the HPS induction and the two CHPs . By this point , research has demonstrate that you’re able to mature gerberas well under full light-emitting diode if you control the greenhouse climate slightly differently . We were already prepared for that , so it was in the main a matter of alright - tuning . "
gamey adjustable lighting levelBased on knowledge , experience , and proven reliableness , the entrepreneur started work with Philips Horticulture LED Solutions and installer Stolze . " Philips Horticulture LED Solutions has the most knowledge and experience in the playing area of LED , supplies high - quality equipment , offers serious support , and ask responsibleness during the project , " he explain . " After a few conversations , we decided on a Philips GreenPower LED toplighting force induction that delivers a level best of 205 μmol / m2 / sec . That ’s 50 % more than the HPS installation we had . With the GrowWise Control System , we can control the light story as desired . "
grow differentlyIn October 2022 , the installation was quick for role , and the lights were turn on . Since the LED induction emits hardly any radiant heat to the crop , and HPS spark do , the cultivation method had to be conform more or less . In particular , wet control in the other dawn requires extra aid .
Mans : " As before long as the lights are call on on , the plants take off to evaporate . To keep crop condensation in the still cold plants and to promote moisture removal from the crop , you must gently increase the tripping level and crop temperature and stimulate line circulation through the crop . "
At the same clock time , the absolute humidity in the nursery needs to be reduced . We have breeze deal whole for this in the façade . They draw in relatively dry external air , fire up it , and bring it under
the crop via statistical distribution hoses . On its way up , the aviation hire up moisture from the crop . We can also ventilate internally with this . "
40 % less energyCompared to previous years , the atmosphere handling has put in more hours for dehumidification . If the humidness deficit drops below 2.5 g / kg , it will unify in outside air . They also screen more because the energy sieve remained fill up on dark days to retain the warmth .
Mans : " Thanks to the effective LED installation , push consumption for lighting was 40 % lowly than the year before despite additional firing hour . With LED , you may bear on to use ignition on relatively dark , tender day in give and fall . That ’s not possible with HPS because you do n’t need that extra radiant rut . "
Topline Gerbera only used one CHP for lighting . This allows the kindling installation to melt at 75 % mental ability , which comes down to 165 μmol / m2 / sec . Mans bring : " We mainly used the second CHP for power supplying to the grid and for high oestrus demand . It has greatly improved our energy efficiency and flexibility , despite the slimly in high spirits heating plant curve we had to adopt due to the lack of effulgent warmth from the lights .
Flower quality and productionThe raiser aver he has n’t had much fuss with Botrytis and efflorescence rot ( so - called ' guff head ' ) . In his view , this proves you’re able to cultivate flowers very well under full light-emitting diode . The production was good , and the quality even improved slightly and was well above average .
" We reap heavier flowers with deep stem and large bloom diameters , " said Mans . " They should n’t get any heavier either because there is no redundant benefit to that . The challenge for the number season is to commute the eminent lightsome levels into more flowers . Perhaps the temperature will have to go up a degree during the day . It would be nice if that could be achieved . We are pleased with the new lighting installation and how the transition to full LED went . "
Monitoring first lighting seasonGrowing genus Gerbera under full LED according to the principles of Plant Empowerment is not without challenge . Many growers who have taken this step in recent old age are having more problem with moisture control and Botrytis . To see how recently acquired new penetration influence out in practice , Mans and Philips Horticulture LED Solutions cooperate on a widely - ranging monitoring project within the framework of ' Kas als Energiebron , ' with input from researcher , Priva , and polish adviser . The final result of this have been shared in a merging with the harvest cooperative Gerbera . This made it potential to share and apply the positive experiences gained in the first light season at Topline Gerbera widely .
