In recent years, smart plant factories have become very popular. By adjusting LED lighting, moisture, and nutrients, the crops have been moved into the interior from the outdoors, providing the best growing environment for plants, efficiently combining technologies such as LED and agriculture to build a smart plant factory.
LED lighting can not only provide suitable growth environment for plants, but also accelerate its growth rate and increase nutritional value. At the same time, the LED lighting is not subject to environmental interference. For those countries where the climate is not suitable for plant growth or land constrained, the plant lighting can be said to be One of the best choices.
Russia's super-large LED greenhouse, with 40 football stadiums
The Russian greenhouse agricultural production company LLC Agro-Invest uses LED plant lighting for growing tomatoes and gherkins. It covers an area of 25 hectares and has 40 football pitches. This project is by far the largest horticultural LED lighting project with a large target. Increase production and save 50% more energy than using traditional high-pressure sodium lamps.
Irina Meshkova, vice president and chairman of Agro-Invest, stated that LED plant lighting is definitely the future trend. LED products can provide the most suitable lighting for plants at the time and location where the plants most need lighting. Compared with traditional lighting, LED products can be greatly reduced. The heat generation caused by LED also increases the output of agricultural products during the weak light months of the year, and can also reduce the large amount of energy consumption, showing the trend of large-scale plant lighting in the world.
Canadian marijuana will be legalized, hope LED lighting saves huge power consumption
Due to Canada’s imminent legalization of marijuana in July 2018, Canadian cannabis growers began mass production, but marijuana planting requires huge amounts of electricity. In order to reduce the cost of producing marijuana, tech companies have begun to study LED lighting technology, hoping to Reducing the amount of energy needed to plant marijuana is expected to use LED lighting to reduce lighting costs by 50%.
According to the study, an average of 2 kilowatts of electricity is required for each pound of marijuana produced, while 2 kilowatts of electricity is equivalent to two months of electricity for a Canadian average family, while Canada has 47 licensed cannabis producers in Ontario. It is estimated that these cannabis producers will consume 1% of the electricity consumed in Ontario each year.
The proportion of different types and different colors of LED lighting can change the growth of plants and achieve the goal of controlling the growth and quality of plants. In the case of marijuana, for example, increasing the red light and reducing the blue light will reduce the THC content of tetrahydrocannabinol in cannabis and vice versa.
New Zealand greenhouse uses LED plant lights to improve tomato quality
LED technology can also help farmers in different regions to allow them to respond more accurately to climate change. In the case of growing tomatoes, Philips Lighting teamed up with New Zealand Food Group Gourmet Mokai to use LED grow lights to improve the quality and cost-effectiveness of tomatoes. In January 2018, a new 4,500 square meter (about 1,316 ping) greenhouse installed on the North Island. LED lights.
Gourmet Mokai uses New Zealand's natural conditions to grow plants, uses geothermal steam for heating, uses hydroponic methods to grow tomatoes, and then installs LED lights between plants and plants. Roelf Schreuder, Gourmet Food Production Director, points out that he hopes to improve the taste, vitamin C content and food shelf life of tomatoes through specific LED spectra.
Dutch growers use LED-assisted lighting to stimulate lily production growth
In October 2017, a horticultural LED lighting experiment was carried out in the Lily grower Together2Grow in the village Poeldijk in the south of the Netherlands. It is reported that Together2Grow and Praxay have cooperated to use LED lighting as an assistant to high-pressure sodium lighting in greenhouses and to experiment with planting lily varieties of Virginia. The test results show that lily production increased by 20% with 7 weeks of solid-state lighting.
The test range is controlled in the existing high pressure sodium lighting environment, while the high pressure sodium lamp can provide 70 μmoles/m2/sec photosynthesis photon flux density (light intensity). In the solid state lighting test, there are 7 installed next to each 1000 W high pressure sodium lamp. For Plessey Attis LED lamps, photosynthesis flux density increases to 130 μmoles/m2/sec. The test results show that in the solid-state lighting environment, the production of flowers is increased, and it is more flourishing.
In addition to the 20% increase in output, the average lily bulb even grows by 2 grams in LED horticultural lighting. It is reported that LED lighting system combines far-infrared, ultra-red and blue LEDs. Praxay said that LED lamps are 40% more efficient than high-pressure sodium lamps.
