According to reports, the shape is like a fish tank, sowing the nutrient solution, and after plugging in the electricity, the lettuce can be harvested after 22 days. The author learned from the 2014 China International Semiconductor Lighting Application Technology Forum held yesterday that the mini LED “family farm†was first launched, allowing citizens to experience the fun of an urban farmer at home.
The author saw that there are lettuces with different growth times in the mini device. The staff said that 12 kinds of lettuce can be planted in each tank, and they can be eaten after 22 days, while in the natural state, it takes 62 days. “The main thing here is that smart LEDs are playing a role.†Li Yuzhi, manager of the comprehensive evaluation department of Shanghai Semiconductor Lighting Engineering Technology Research Center, told the author that this is the latest version of the family farm. “It’s not enough to grow a wave of lettuce.†Currently, lettuce Leafy vegetables such as small green vegetables and chicken feathers can be grown and can be grown all year round.
Researchers explained that photosynthesis can be promoted by the opening and closing of LEDs. If you open for 3 hours for one hour, one day is equivalent to 6 days of natural state, and it will not be greatly affected by nutrition. The product is more than 1,000 yuan due to the high price, including half a year of seeds and nutrient solution. However, as product promotion and cost decline, prices will decrease.
