Fluence has been selected by Wageningen University & Research (WUR) as the lighting provider for Serre Red, the university’s new, high-tech quarantine greenhouse. Serre Red will be used for critical research on plant diseases—caused by viruses, bacteria, fungi and parasitic nematodes—including quarantine pathogens, as well as research on genetically modified organisms.

Built by Bosman van Zaal, Serre Red is one of the most advanced quarantine research facilities constructed to date. It features 63 compartments, ranging from 15 to 52 square meters with individual climate control, air filtering and access locks. Extensive technical equipment has been installed in a corridor sunk below ground level to avoid excess shade. Other features of the fully electric greenhouse include insulated double glazing, external shading, heat/cold storage and autoclaving, which sterilises all materials including water and waste before leaving the greenhouse.

Broad spectrum lighting:
Choosing LED over HPS

To reduce the influence of artificial light on their experiments, WUR’s researchers required broad spectrum lighting. Unifarm, the university’s greenhouse and field research facility, ran a market consultation during November and December 2019, then selected four manufacturers from a tender in January 2020. Fluence was granted the order in April after the four potential solutions were examined by WUR’s scientific committee.

“Traditionally, our greenhouses are equipped with HPS lighting,” said Dolf Straathof, head of Unifarm. “As we want to eliminate any influences that artificial lighting could have on experiments, we looked for a solution that came closest to the spectrum that our scientific team specified as optimal.”

“Fluence was one of those consulted, and they proposed higher light levels than we initially specified, which concurred with recommendations from our researchers,” Straathof continued. “The PhysioSpec® solution that Fluence proposed also fit our spectral requirements. In the end, Fluence offered us the best possible solution and exceeded our requirements for uniformity, offering the highest uniformity for a mix of low and tall crops throughout all compartments.” 

Optimising light levels and uniformity

Each compartment will have individual lighting controls, linked to the Hoogendoorn climate control system. “This is the first time WUR has chosen LED, and specifically broad spectrum LED, as their standard lighting solution for a research greenhouse at Unifarm,” said Theo Tekstra, Fluence’s technical director in Europe, the Middle East and Africa and lead for the project’s design and implementation. “LED solutions have the added advantage that they can be controlled without change in spectrum or loss of efficiency, offering constant light levels and optimal daily light integral. By using our compact VYPR 2×2 full spectrum LED fixtures with the new compact PSU drivers and VYPR reflectors, we minimize shading and optimize overall uniformity. We are extremely proud that our solution was selected as the best in the tender and that we were awarded the contract for this prestigious project.”

Critical research for the world’s growers

Fluence supports, sponsors and collaborates on horticultural research projects throughout the world, including its membership in the Wageningen Research Club of 100—part of the WUR Business Unit for Greenhouse Horticulture in Bleiswijk.

The spread of viral infections—such as the tomato brown rugose fruit virus (ToBRFV)—remains a top concern for growers throughout the world. The new Serre Red facility enables WUR to expand and intensify its research capabilities, maintaining its position as a world leader in research on horticultural crop pathogens.

“ToBRFV currently threatens tomato, bell pepper and chili pepper crops throughout the globe, causing most production greenhouses to close to visitors and creating increased costs for growers through extensive disinfection and other precautionary measures,” said Dr. Theoharis Ouzounis, horticultural scientist at Fluence. “There is no treatment other than prevention and pervasive damage has been reported globally. Research into prevention and treatment of viral diseases is extremely important to safeguard our food production.”

PRESS RELEASE

 

Enhanced spectra offering empowers growers to balance lighting efficacy with crop quality and yield

 

AUSTIN, Texas (June 4, 2020) — Fluence by OSRAM (Fluence), a leading global provider of energy-efficient LED lighting solutions notably for agriculture production, announced the launch of four additional spectra on its VYPR top light series, featuring market-leading efficacies up to 3.8 µmol/J. From broad white to high red, Fluence’s extended PhysioSpec™ spectra enable growers to optimize lighting strategies for any crop in any growth stage or geographic location.

“In our relentless pursuit of innovative lighting solutions for crop cultivation, we’ve conducted in-depth research on plant response under various spectra with a range of crops,” said David Cohen, CEO of Fluence. “One of the biggest challenges for cultivators around the world is the ability to tailor lighting strategies to their specific crops and environments. We’re excited to help them solve that challenge with a greater variety of light spectra to meet their unique needs.”

With expanded PhysioSpec™ spectra, the VYPR top light series offers higher efficacies (up to 3.8 µmol/J) and higher photosynthetic photon flux (PPF) (up to 2330 µmol/s) per fixture over comparable lighting technologies.

  • The PhysioSpec™ BROAD spectra offers continuous spectral emission across PAR 400 to 700 nm wavelength range, balancing energy efficiency with quality of light for desired plant response and human work environment.
  • The PhysioSpec™ DUAL spectra features red and blue spectral emission bands that maximize energy efficiency, helping to reduce energy costs and operational expenses for growers.

The latest VYPR top lighting system also features a patented thermal management technology, more compact and efficient power supplies, three new mounting options for flexible installation and new reflectors. Built for greenhouses and high-bay indoor cultivators producing year-round, the VYPR series enables growers to maintain predictable production, increase crop yields and improve plant quality compared to conventional production systems.

“Growers have the best understanding of their crops in their respective cultivation environments,” said Timo Bongartz, Fluence’s general manager for Europe, Middle East and Africa. “Choosing and implementing a supplemental lighting strategy should be a collaborative process. With our expanded spectra and new top light features, we are empowered with more tools to help our customers achieve their growing targets, enabling growers to save energy when possible, optimize light uniformity and increase light levels.”
