LED grow light greenhouse plant Applications

We often say that the smart lighting, not only as family life saving devices exist, and now, with the continuous development of technology, applications are increasingly widespread up, in order to meet consumer demand for locally produced fresh tomatoes in the non-seasonal when the season, greenhouse farm typically rely on additional lighting device planted tomatoes. The farmers began to notice the advantages of led grow lights, energy-efficient led grow lights because of advantages that can be used to replace a greenhouse HPS (HPS). A recent study of the feasibility of using led grow lighting in greenhouse tomato provides some information.

From the Department of Agriculture and Landscape Architecture at Purdue University's MichaelDzakovich, CelinaGómez and CaryMitchell in HortScience published research results. They point out the led grow lighting is becoming an alternative to the high-pressure sodium lamps. They said: "For people to use led grow lights as a light source of high-value crops in the greenhouse, plant-based hormone levels affect the sense of smell and quite curious but so far hardly any fruit crop for a long time to accept the led grow light irradiation, grow into maturity. correlation tomato. "

The researchers conducted three separate studies, surveys affect the amount and quality of supplemental lighting for greenhouse tomatoes planted it. Plants are completely received natural sunlight control group, natural sunlight plus HPS lamp auxiliary lighting, and natural sunlight supplemented by LED grow lights. Scientists collect color, sugar content (Brix), titratableacidity (titratable acidity), conductivity (electricalconductivity) pH and acid-base analysis of plant responses to lighting. The researchers said: "In contrast to our previous assumptions, fruit quality LED auxiliary light source is completely free from the impact."

The study also contains invited teams try to eat tomatoes color, acidity, sweetness ranking, combined use of measuring instruments. Try to eat personnel must also be assessed for the color of tomatoes, aroma, texture, sweetness, acidity, aftertaste and overall sense. "Income and try to eat after biochemical and practical information we can decide whether to receive the endorsement of the physico-chemical data are also reflected in consumer awareness of the quality of tomato."

Try to eat a data indicative of the difference can not be materialized for them to distinguish by tasting; in fact try to eat a completely unable to distinguish the use of different auxiliary lighting of tomatoes and tomato absolutely no difference obtained between the auxiliary light source.

Studies have shown that the quality of greenhouse tomato is not only accepted a very subtle differences between the data or not auxiliary lighting effects materialized measure the resulting difference is displayed in the control group, and after tasting a fine staff confirmed these differences to be difficult to discern.

The researchers said the results of this study have a positive meaning for those who want to import greenhouses led grow lighting for farmers. "LED auxiliary light source intensity and wavelength does not have any negative impact on the quality of the results of greenhouse tomato, and showing the led grow light source is suitable as overheating problem HPS lamp replacement light source."
