LEDs found to increase yields in wide range of plants

By -
Research found that 32 days after they were planted and nourished under LED light, tomato plants showed a 45 percent increase in height and a 28 percent increase in weight.


Improvements in weight, morphology, flowering, root development and flavour have been spotted in plants grown under supplemental LED lights in greenhouses.
Tomato plants have been found to show a 45 per cent increase in height and weight when cultivated under LED lights.
The new research, which was conducted by LumiGrow, who develop LED technology for use on farms, noted an increase in flowering observed in cucumber plants, as well as a reduction in the spread of powdery mildew, which is a common problem.
Increased flowering rates were also found in tomato and cannabis plants. The research also aimed to pinpoint the optimum supplemental LED light intensity for strawberry production.
The research was presented by Dr. Xiuming Hao and Shalin Khosla of Harrow Research and by Dr. Melanie Yelton, who is vice president of research at LumiGrow, to an exclusive grower’s council at Harrow Research and Development Centre.
A broad range of growers made up the audience, including vegetable, floriculture and cannabis producers, all looking to take full advantage of the LED revolution in horticulture.
The research found that 32 days after they were planted and nourished under LED light, the tomato plants showed a 45 percent increase in height and a 28 percent increase in weight.
Improvements in weight, morphology, flowering, root development and flavour were also spotted.
LumiGrow’s inventive Grow Light Sensor technology was also displayed and discussed at the meeting. The sensor is able to measure and monitor ambient light from the sun and then analyses this collated information to decide how much supplemental LED light is required in the greenhouse to keep conditions consistent.

Here comes the moon: CoeLux launches night version

'The moon, unlike the sun, lets you look at her, it seems she wants to be looked at', commented Paolo Di Trapani, CEO of CoeLux, who is behind the latest innovation. CoeLux Moon aims to create a comforting and relaxing ambience and less light is used to produce the final effect than the original sunlight CoeLux uses. CoeLux’s artificial skylights have rocked the industry due to their convincing reproduction of sunlight. Now the company has launched a new version that aims to be just as successful at recreating the night sky. CoeLux Moon is being launched at Euroluce 2017, which is currently taking place in Milan. ‘The moon, unlike the sun, lets you look at her, it seems she wants to be looked at,' commented Paolo Di Trapani, CEO of CoeLux, who is behind the latest innovation. CoeLux chose last year’s LuxLive to launch the second generation of the CoeLux daylight range, which is comprised of smaller less costly fittings. ‘By rebuilding the phy...

Is Dali dead?

Will the Dali protocol survive in the age of the ‘internet of things?’ Lux asked five experts to debate the future of the protocol. From left: Tad Trylski, Wayne Howell, Sam Woodward, David Mooney and Andrew Glossop Calm down everybody, Dali is not dead yet. That was the consensus in a discussion on the future of the lighting control protocol at   Lux 's Smart Lighting Controls Europe 2015 conference. Dali continues to evolve, resolve its issues and respond to the needs of the lighting industry. But even so, its fate could end up being decided by forces much bigger than the lighting industry itself, and the user could be worse off, according to one expert. ‘The IT industry will take over and make the decisions for us. They’ll make protocol changes, they’ll adopt standards and we will have to live with what they want because their market is bigger than ours,’ said David Mooney, an associate at Atkins who took part in a panel discussion on Dali. "Lighting is almost un...
