Recently, Fluence, a subsidiary of Osram, released a press release saying that the Wageningen University And Research Center cooperated with Fluence and greenhouse agriculture consultant Vortus to release preliminary results of an experiment. The feasibility of the full spectrum LED lighting solution for plant growth.
The data show that for some tomato varieties, the full spectrum LED grow light is used to increase tomato yield by 11% compared to high-pressure sodium lamp and is more energy efficient.
The press release showed that the study was conducted on Tomaino and Malice tomato varieties, and Dr. Ep Heuvelink of WUR and his team compared the effects of high-pressure sodium light and a full spectrum LED plant light.
Virtus owner Barend Lobker said that many growers now use high-pressure sodium lamps as the only source of light for the greenhouse, and the WUR test proves that there is a better solution. Planters are not sure if LED lamps will be able to grow crops equally effectively, so they have been reluctant to switch to LED lights. The WUR test this time eliminates any doubts about the performance of full-spectrum LED grow lights.
Fluence's horticultural service expert and senior photobiologist Haris Ouzounis said that this is a very exciting result for the application of full-spectrum LED technology in the greenhouse. The trial demonstrates that even without any environmental optimization, full-spectrum LEDs can match the needs of commercial growers.
