Have you avoided the minefields of using fill lights in greenhouses?
Greenhouse planting is becoming more and more popular. As a lamp that can provide light to plants anytime and anywhere instead of sunlight, the use of fill-in lights in agricultural planting has also increased in recent years. Whether it is greenhouse planting, home planting or plant factory, plant fill-in lights can be used, but there are many things to pay attention to when using plant fill-in lights. It is not enough to simply add fill-in lights to plants. When using fill-in lights for fill-in lighting, there are many minefields to avoid, and timely adjustments should be made according to actual conditions.
After adding plant fill-in lights to greenhouse or greenhouse planting, pay attention to adjusting the distance and position of the fill-in lights. Adjust the installation distance of the fill-in lights according to the size of the greenhouse area and the growth size of the plants. If the fill-in lights are only for simple fill-in lighting, they can be slightly closer to the plants. If the fill-in lights also have a heating effect, they should be farther away from the plants to prevent damage to the plants.
When using fill-in lights, pay attention to the time of filling lights for plants. Try to avoid using fill-in lights after the crops have just been transplanted. You should wait until the plants have grown normally after the seedlings have been slowed down before using fill-in lights. In addition, when using fill-in lights to supplement the light for plants, the lighting time and light intensity should be flexibly set according to the type of plants. Different types of plants have different requirements for the time and intensity of light. In addition, the requirements for light are also different at different growth stages of crops. According to the growth status of the plants, choose whether to use red, blue or full spectrum fill-in lights in combination with actual conditions.
Plant fill-in lights are generally used when there is insufficient light on cloudy, rainy or foggy days. It is necessary to combine the growth of plants with the local lighting environment to give plants appropriate light supplements. It is absolutely impossible to use fill-in lights for plants 24 hours a day. Plants also need time to rest and breathe.
When using plant fill-in lights in greenhouses, pay attention to moisture-proofing. You can add reflective film on the ground to increase the utilization rate of light by using the refraction of light, so that the middle and lower parts of the plants can also get more light.
