Another step towards year-

round production

Le Jardin de Rabelais,
Avoine, France


Pascal Delahaye explains: “We don’t need more tomatoes in summer, but we do in winter. For us, artificial lighting is a step on the path towards year-round uniform production.” The grower opted for one of the latest developments in artificial lighting: LED interlighting.

We wanted
a heavy-duty lighting

installation that didn't raise the plant temperature.”

Customer challenge


Because of the French climate, Le Jardin de Rabelais needed a more heavy-duty lighting installation, without increasing the plant temperature too much. “This is why I was interested in LED lamps, which produce far less heat than HPS lighting”, Delahaye explains.
 

The right lighting 

 

Le Jardin de Rabelais deliberately targets the higher-end segment of the market. For its nursery, Delahaye grows the Piccolo variety, which has a superb taste but is not easy to grow.


To increase the amount of light in the greenhouse, without further raising the temperature, Delahaye decided to install Philips GreenPower LED interlighting in two strands, which has a total intensity of 110 μmol/m2.s. This means that the total capacity of the nursery, together with HPS toplighting, is now 235 μmol/m2.s. Delahaye: “Together the lighting systems provide a plant reaction that is equivalent to 285 μmol/m2.s, a huge leap forward”.

 

Remarkably, the installer performed the entire operation in a greenhouse covering an area of 16,000 m2 that still had crops growing in it. “In fact we never have a break from producing, since we want to serve the market all year round,” explains Delahaye. In addition, the LED interlighting system can be hoisted, which was thought up by Horti LED partner Certhon and means that the interlighting can ‘grow along’ with the crop.

The interlighting module is a bi-directional lighting module for interlighting in between tall plants e.g. tomatoes.
