Dutch growers use LED-assisted lighting

According to reports, the United Kingdom Pleasant announced a lark flower gardening LED lighting test results, the experiment in the southern part of a village of Poeldijk lily growers Together2Grow carried out. It is reported that Together2Grow and Pleasant cooperation LED lighting as a greenhouse in the high pressure sodium lamp lighting assistance, and the greenhouse for the cultivation of Virginia varieties of lilies. The results showed that lily production increased by 20% with the aid of solid-state lighting for 7 weeks.

It is understood that lilies, also known as Narcissus lily, yellow six flowers or parrot lily, produced in South America, is now all over the world. Pleasant had previously published several gardening lighting tests, one of which tested tomatoes. In all cases, solid-state lighting is an auxiliary energy source for plants.

It is understood that the test range is controlled in the existing high pressure sodium lamp lighting environment, while the high pressure sodium lamp can provide 70 μmoles / m2 / sec light quantum flux density (light intensity), solid state lighting test, each 1000W high pressure sodium lamp installed next to 7 Plessey Attis LEDs, the light quantum flux density is increased to 130 μmoles / m2 / sec.

The line graph shows the cumulative yield of the stem per hectare lily and compares the different results of the high pressure sodium lamp illumination and the LED gardening lighting.

Test results show that in the solid state lighting environment, the flower yield increased, and opened more lush. "At present, I am very satisfied with the results of the test, in the LED lighting conditions, the plants look more lush and healthy, and the output has increased." Said Bernard Zuidgeest, co-owner of Together2Grow.

With only more light, without the need for additional radiant heat, the plant still retains the temperature of the normal plant. We are working with Pleasant to experiment with more plant varieties to transform the greenhouse into a hybrid lighting system. "

In addition to 20% of the output growth, in the LED gardening under the lily of the average growth of each root more than 2 grams. It is reported that LED lighting system combines far infrared, super red and blue LED. Pleasant said that the efficiency of LED lights higher than the high pressure sodium 40%.
