How to use LED grow lights to get better effects?
Among the many grow lights, the LED plant light is one of them, and it is also the most widely used grow light in recent years. Because compared with other traditional plant lights, LED plant lights have more advantages, such as: less heat, small space, low power consumption, etc. And there are clear data showing that LED plant lights can increase the output of crops. More and more people choose to use LED plant lights to fill light, so how to use LED grow lights to have a good effect?
1. Pay attention to the choice of LED plant lights
If you want to use LED plant lights with good effects, you must first choose the LED plant lights of the appropriate crops when choosing. Different crops have different requirements for illumination and light intensity, so pay attention to the spectrum and power of LED plant lights. For crops that need coloring and flowering and fruiting, you can choose red and blue LED plant lights. For leafy vegetables, you can use full-spectrum LED plant lights. For light-loving plants, you should choose high-power LED plant lights.
2. Pay attention to the distance between led grow light and your plant
Plant lights will have a certain amount of heat. If they are too close, they will burn the plants and cause certain damage to the plants. However, if the distance between the plant lights and the plants is too far, the light utilization rate will be greatly reduced, thereby weakening the supplementary light. effect. And if the heat of the LED plant light is less than other plant lights, but there will be a certain amount of heat, and if the distance is too far, it will affect the effect of light supplement.
3. Pay attention to the fill light time
If the weather is fine, you can add light to the plants for 2-3 hours in the morning and evening when the light is weak. If it is cloudy, rainy or hazy, you can add light to the plants throughout the day. Moreover, there is a time limit for supplementing light to plants. It is most suitable for plants to have 14 hours of supplementary light in a day. They also need to rest at night and take time to breathe.
The tips for buy led grow light
At first, determine What Plants You Are Growing. Before buying led grow lights, you must know where you’ll use them for.
Know the Plant Area. Learn about the area you plant.
Consider the PAR/PPE.
Growth lamp efficacy, also known as photosynthetic photon efficacy or PPE, is the output of PAR (photosynthetic effective radiance) photons divided by the wattage of the lamp. The efficacy of the growth lamp has quickly become one of the main indicators for buyers to evaluate products.
The higher the PPE, the better the effect of reducing power consumption, but this indicator also has its limitations. For example, PPE only considers photons in the PAR spectrum (not including wavelengths such as far-red light).
Ensure It Has a Proper Cooling System.
Notice the spectral range of the led grow light. Plant photosynthesis absorbs the most red and blue light. When we choose led grow light, we select the most red and blue led plant light. But when choosing, we should learn about the wavelength range of the led grow light. The red light around 660nm and the blue light around 450-470nm have the most obvious effect on your plant.
Heat output of led grow light
The LED grow light can overheat, especially if you use it for at least 15 hours a day for sufficient light for the plants. As mentioned, excessive heat can be harmful to your plants and the led grow light itself. So your LED grow lights should have an efficient cooling system.
The heat in LED light happens at the back, so that area should have a heat sink. It moves the heat away, so it doesn’t overheat the led grow light or the plants.
The planting environment
Such as the lighting conditions of the area, the shading condition, the height of the lamp can be hung, etc., provide a reference for the selection of the lamp body material, the light source type (hot or cold light source) and the hanging load.
Easy to install
Commercial LED grow lights are installed above the plant canopy, and depending on the distance between your shed roof and the plants, you need to ensure that the grow lights can be easily installed and replaced.
In the greenhouse, most commercial LED grow lights are installed on pillars running through the top of the facility. In indoor planting rooms, hangers, pulleys are usually used to attach to pillars, or to vertical plant racks.
Generally, it is smart to understand the manufacturer’s installation process before buying. A good manufacturer must also have a well-thought-out system that is easy to install, replace and expand.
Is the led grow light good for full spectrum or red and blue light?
Plant lights can replace sunlight to supplement light and promote plant growth. They can be used when planting vegetables, fruits and flowers. They can not only promote the growth of seedlings, but also promote flowering and fruiting, increase production and market in advance. There are many types, and the spectrum has full spectrum and red and blue light spectrum. Is the full spectrum better or the red and blue light spectrum?
After studying the absorption and utilization of sunlight by plant growth, people have found that the absorption and utilization of red and blue light in sunlight is the largest by plants. Red light can promote plant flowering and fruit, and blue light can promote plant growth, stems and leaves. So in the later research on plant lights, people developed plant lights with red and blue spectrum. This kind of lamp has the best effect on supplementing light for the growth of plants, and it has better effect on crops and flowers that need to ensure the color. Moreover, the red and blue light can be matched according to requirements to obtain the most suitable spectrum for plant growth.
Red and blue plant lights have only two spectra of red and blue light, while full-spectrum plant lights simulate sunlight. The spectrum is the same as sunlight, and the light emitted is white light. Both have the effect of supplementing light and promoting plant growth, but different crops should pay attention to choosing the most suitable one when choosing the spectrum.
For flowering and fruiting crops and flowers that need to be colored, it is best to use red and blue plant lights, which can color, promote flowering and fruiting, and increase yield. For leafy crops, full-spectrum plant lights can be used. If you grow plants at home, it is best to choose a full-spectrum plant light, because the light of the red and blue plant light is pink, if people stay in this environment for a long time, they will feel dizzy, nauseous and unwell.
