The growth of plants requires light energy to reach between the light full point and the light compensation point, that is, to reach a certain light intensity. The change in the power of the LED grow light directly affects the change of the light intensity. As for the higher the power of the LED grow light, the better. The question is divided according to the characteristics of the plant. The following is a detailed analysis for you.
For light-loving plants, the greater the power of LED grow lights, the better. Because the higher the power, the stronger the light intensity. The light-loving plants need stronger light intensity to reach the light-full point and the light compensation point in order to promote the photosynthesis of the light-loving plants and achieve the desired effect of the light-loving plants.
For plants that do not have that strong demand for light, the greater the power of the LED grow light, the greater the effect is not so good, because its light saturation point and light compensation point are relatively low. When the light intensity exceeds the light compensation point of the plant , The plant will not undergo photosynthesis, and it may burn the plant and affect the growth of the plant.
Pay attention to the fill light time
If the weather is fine, the plants 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, plants can fill up the light all day. Moreover, there is a time limit for plants to supplement light. Plants 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.
Pay attention to the fill light distance
LED grow lights will generate a certain amount of heat. If they get too close, they will burn the plants and cause some damage to the plants. However, if the distance between the LED grow light and the plant is too far, the light utilization efficiency will be greatly reduced, 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. At the same time, if the distance is too far, it will also affect the effect of fill light.
Pay attention to power selection
If you want to use LED grow lights to have a good effect, you must first choose the right LED grow light crops. Different crops have different requirements for contrast and light intensity, so pay attention to the spectrum and power of LED grow lights. For crops that need coloring and flowering, you can choose red and blue LED grow lights. For leafy vegetable crops, you can use full-spectrum LED grow lights. For plants that like light, you can choose high-power LED grow lights.
Pay attention to the ratio of red and blue lamp beads
The ratio of red and blue LED grow lights is the ratio of red and blue lamp beads. Because there are many kinds of plants at present, even if the data is not perfect in all aspects, if you want to know the ratio of red and blue accurately, the data can only be used as Reference section.
At present, everyone refers to the data based on the ratio of sunlight spectrum, and adjusts flexibly according to the field planting situation and crop types and functions. The ratio of red to blue light of the sun is about 6-8:1. People refer to this to conclude that flower foliage or leaf viewing For vegetable-like plants, the configuration should be less than 6-8:1, so that the blue light is a little bit more, and the blue light has a promoting effect on the growth of plant leaves. For flower viewing, choose 6-8:1 or more for supplementary light during the flowering period to let more red light. Red light has a significant effect on the flowering and fruiting of plants. For other growth stages, follow the sunlight reference ratio, and choose 6-7:1.
Choose the most suitable LED grow light according to the actual situation, and choose the LED grow light suitable for your plant, it will definitely have an effect.
