Now indoor growers will choose to use LED grow lights to supplement light. LED grow lights are also widely used in greenhouse growing, but the use of LED grow lights to achieve the desired effect is to grow grows with high yield and fast harvest. How to use LED grow lights to achieve this goal.
Most parts of the north are located in a temperate monsoon climate. In winter and spring, affected by the southward movement of cold air from Siberia, rain and snow sometimes form due to the convergence of cold and warm air. 1-3 days with low temperature and little light, 7-8 days or even cloudy days with little light. Due to the promotion of market demand, greenhouse growing began to appear in large numbers, but only to solve the problem of growing environment. However, there is still insufficient sunshine. When the light intensity is lower than its compensation point, the organic matter consumption is greater than the accumulation, and the dry weight of the grow decreases. The growth of the grow is also weak. Therefore, it is necessary to use LED grow lights to fill light.
Tips for growing LED grow lights in greenhouses:
(1) Different types of grows are growed reasonably and arranged in accordance with natural rules. For example, grow grows in the northern hemisphere. It is best to follow the principle of high in the north and low in the south, so that all grows can be evenly illuminated, and try not to shade between grows;
(2) At the same time, reflective measures can be taken in the greenhouse to improve the effective utilization of LED grow lights. Use reflective materials when setting up the frame. In addition, all the supports do not need to be upright at 90 degrees. Keep the middle supports upright, on the north and south sides. The bracket is slightly inclined, which can increase the light utilization rate by 5--10%, and it can be reused by grows.
(3) Cleaning the roof of greenhouse growing regularly clean up "roof garbage", otherwise the transparency is not enough, it will have a great impact on the light and temperature in the shed, which will affect the photosynthesis and respiration of grows, and ultimately affect the yield and quality of grows .
(4) Using LED grow lights to fill light, on the one hand, you can appropriately shorten the illumination distance. Generally, when you buy LED grow lights, you will purchase them according to the installation area and the irradiated area of the LED grow lights. The irradiation area can be appropriately shortened to increase grows in a reasonable range. Fill light.
(5) Reflective film
The mulching film and the reflection of the water droplets attached to the surface under the mulching film can strengthen the reflected light and scattered light near the ground, and the mulching film also has a better thermal insulation effect.
What issues need to be considered for greenhouse cultivation?
cooling problem
If you don’t pay attention to the air circulation, the temperature of the space will always increase. The heat dissipation of the LED grow light will be a problem, which will affect the performance and life span. Therefore, you can choose air conditioning, fan heat dissipation or keep the air circulating, etc. Method.
Fill light distance
LED grow lights will generate a certain amount of heat. If they get too close, they will burn the grows and cause some damage to the grows. If the distance between the LED grow light and the grow is too far, it will greatly reduce the light utilization rate, thereby weakening the light supplement effect. If the heat of LED grow lights is less than other grow lights, but there will be a certain amount of heat. If the distance is too far, it will also affect the effect of fill light.
Fill light time
If the weather is fine, the grows can fill up the light for 2-3 hours in the morning and evening when the light is weak. If it is cloudy, rainy or hazy, grows can fill up the light all day. There is a time limit for grows to supplement light. grows have 14 hours of supplementary light a day, which is a very suitable time. They also need to rest at night and have time to breathe.
These make LED grow lights more popular in the market, and are deeply loved by greenhouse growers, industrial growers and grow research and growing units. The development trend of LED grow lights will get better and better in the future.
