LED plants grow light is an artificial light source that uses LED as the illuminant to meet the lighting conditions required for plant photosynthesis. According to the type, it belongs to the third generation of plant growth lamps!
Short ultraviolet rays can inhibit the growth of plants, prevent excessive growth of plants, have disinfection and sterilization effects, and reduce plant diseases.
Visible light is the raw material for green plants to produce organic substances through photosynthesis. Green plant chlorophyll absorbs the most red-orange light, followed by blue-violet light, and the least absorption of yellow-green light.
Far-infrared rays produce thermal effects, which supply heat for the growth and development of crops. Under the irradiation of infrared rays, the ripening of fruits tends to be consistent, and near-infrared rays are useless to crops.
Therefore, in our rapid propagation, the supplementary light in the hydroponics process uses the red light of the LED plants grow light to supplement the light to achieve the maximum utilization rate.
1. During the growth of stem segments, compare the effects of natural light and red light on plant growth. Under natural light, the chlorophyll content first decreases and then increases.
However, the chlorophyll content under red light is higher than that under natural light, indicating that red light can significantly promote the formation of chlorophyll, and this result is more obvious as the number of days of culture increases.
2. Plants grow better under the red light of the plant growth lamp, which may be due to the higher chlorophyll content in the plant, more vigorous photosynthesis, and more carbohydrate synthesis.
Thereby providing sufficient material and energy for the growth of the plant. Let's take a look at the chlorophyll and soluble sugar content under natural light and red light.
3. The soluble sugar content of the 7-day culture was lower than that of the 13th day, and it decreased more under the red light than under the natural light, and the stem segments under the red light also took root earlier than those under the natural light. After 13 days, the soluble sugar content under red light was higher than that under natural light, which may be related to the higher chlorophyll content and stronger photosynthesis under the red light of plant growth lights.
4. The activity of NR in stems under red light was significantly greater than that under natural light, and it can be seen that red light can promote nitrogen metabolism in stems.
In short, red light can promote the rooting of plant stems, the formation of chlorophyll, the accumulation of carbohydrates, and their absorption and utilization.
In the rapid propagation process, the use of red LED grow lights for herbs to supplement light has obvious effects on promoting the rapid rooting of various plants and improving the quality of seedlings.
LED grow lights for herbs are definitely useful for succulents in low-light conservation environments such as indoors and enclosed balconies, but the effect is definitely not as good as sunlight anyway.
Many friends who use plant growth lights and feel that the effect is not good are because you have some problems in the choice of plant growth lights.
First of all, for plants, the wave bands that can promote their growth are basically biased towards red and blue, while our usual lights output the most green bands, which is why our usual lights are useless for succulents.
It is also the reason why the LED plant growth lamps bought online use red and blue lamp beads. If the lamp beads are not selected correctly when choosing a plant growth lamp, it will naturally have no effect.
Some friends may say that other people's LED grow lights for herbs are obviously pink or pink, why do you choose red and blue lamp beads?
In fact, if you have used it, you will know that the visual effect of red and blue light waves will be pink and pink according to the ratio of light waves.
Secondly, the power of LED grow lights for herbs is not enough, which will lead to insufficient light intensity, which is also ineffective for succulents.
Friends who have been growing succulents for a long time know that the effect of direct high-intensity light in just a few hours a day is far better than scattered light in more than 8 hours a day, so if you want the plant growth lights to be effective, power must be an important factor to consider.
