Philips GreenPower LED lighting installations help cucumbers grow year-round

World leader in lighting, Signify, has announced that both Jardins Réunis and Cheminant have installed Philips GreenPower LED toplighting and Philips GreenPower LED interlighting in their new cucumber greenhouses in the Nantes region of France.

This marks the first time LED lighting has been used to grow high-wire cucumbers in France – and solidifies the growers’ leadership as members of the Océane grower cooperative.

“We have experience growing high-wire cucumbers under LED lighting in other parts of the world, and can predict quite well how much production will increase after installing our LEDs,” says Udo van Slooten, Business Leader Horticulture at Signify. “In general, cucumber production goes up with increased light levels. But with LEDs we can truly optimize production by steering light and heat separately. The Philips LEDs have the right spectrum for cucumber growth – the plants use this colour spectrum for optimal photosynthesis, resulting in greater production of a high-quality crop.”


Unique benefits

Both growers expect an increase in production, but that’s not the only reason they’ve opted for full LED lighting. Unlike HPS lighting, LED enables growers to increase light levels without increasing heat. The ability to control light and temperature more precisely guarantees high-quality production as efficiently as possible throughout the year.

“LEDs give a better heat-light balance, generating a significant increase in production without the heat that you would get with HPS lighting,” explains Antoine Cheminant, co-owner of Cheminant. “As per Signify’s calculations, we’re aiming for 30% more production in our 20,000 m² semi-closed lit greenhouse compared to a traditional non-lit greenhouse.”


Productive partnerships

“Signify has worldwide experience in growing high-wire cucumbers under LED lighting, so they can provide us with good advice and support from their plant specialists,” says Vincent Olivon, co-owner of Jardins Réunis. “LED lighting will help us to improve energy efficiency and to reduce gaps in production, especially in the more profitable winter period. This is critical in sustaining our position in the market year-round.”


Like Cheminant, Jardins Réunis installed its lighting in a newly built semi-closed greenhouse. The 25,000 m² greenhouse will use LED toplighting (145 µmol/s/m2) and LED interlighting (67 µmol/s/m2). Installations for both greenhouses were carried out by the French certified Philips Horti LED Partner Eiffage Énergie Systèmes in November 2018. This is the first growing season for both companies to make use of the system.
