LED is the
The 100% LED
60% less electricity and 1.4 less liters of water per kilogram, and produced a 24.8% higher yield."
- Professor Janina Gajc-Wolska, Department of Vegetables and Medicinal Plants
Philips and the Warsaw University of Life Sciences had several goals for this trial. They wanted to prove if it was possible to get high yields of good quality, tasty cucumbers using only LED lighting. They also wanted to investigate the efficiency of using LED interlighting on crops.
The University set up three separate growing compartments for cucumbers. They all applied the same growth light levels, each provided by different lighting technologies.
This trial proved that cucumbers grow really well under 100% LED and it is the most cost-effective way to produce cucumbers in late autumn and early spring. With the LEDs, we were able to reduce our energy costs by 60%. We also used 1.4 fewer liters of water per 1 kg of cucumbers produced, and increased yields by over 24.8% per square meter
In the 100% LED treatment compartment, there were much lower rates of fruit abortion and individual fruits were significantly heavier.“ The fruits grown under 100% LED looked much the same as under HIDs but consumers preferred their taste.”
The interlighting module is a bi-directional lighting module for interlighting in between tall plants e.g. tomatoes.
Philips is introducing an LED-based toplighting solution for greenhouse growers, easy to install and no need for water cooling systems.
