LED lighting has rapidly changed over the time since its introduction into the market. Although they were initially meant to be an alternative to incandescent and compact fluorescent light bulbs, numerous studies have shown that they can be used for, other purposes. Their ability to support plant growth as an alternative to the sunlight is one of the greatest breakthroughs in the agricultural sector.
Full spectrum LED grow lights is something that has sparked excitement in the horticultural lighting due to its numerous benefits. This is something that every grower should have. But what are they?
What is Full Spectrum LED grow lights?
They are special kind of bulbs that produces an artificial sunlight to support plant’s photosynthesis. They are an improvement of the common LED lights. They are simply designed to mimic that natural sunlight to help the plant grow healthier and produce better yields.
It is important to note that plants require natural sunlight to grow healthier and yield better harvests. Apart from what we can with the naked eyes, sunlight includes many spectrums including infrared and ultraviolet. Some of these spectrums are useful to important for the photosynthesis process. Important to note is the red and blue wavelengths that are crucial for the process of photosynthesis. With these LED grow lights, you can grow your plants indoor and get maximum yield as if they were using natural sunlight.
Unlike most of the grow lights, these LED grow lights can consistently emit wavelengths ranging from 380nm to 770nm. This includes visible light to the human and the invisible wavelengths. This range provides all that the plant needs for the photosynthesis. Chlorophyll which is the main pigment for the photosynthesis is sensitive to spectrum peaks at 430nm to 660nm which is provided by the Full spectrum LED grow lights.
Benefits of Full Spectrum LED grow lights
For a long time, the alternative light sources such as high pressure sodium (HPS) have been used as the sunlight alternative in the indoor urban farming. They were highly successful in the agricultural application due to their intense high band of limited nanometer wavelength. Apart from providing a similar wavelength, there are numerous benefits of these LED grow lights that are almost rendering HPS light almost obsolete. Here are the main benefits of Full Spectrum LED grow lights:
1. Less heat and no need ventilation
This is one of the main advantages that these LED grow lights has over the alternative light sources is the amount of heat emitted. For instance, HPS are known for producing excess heat while converting energy to light. With the rising temperatures in the growing space, more water from the plant would be lost through evaporation. It requires expensive venting system or otherwise, the plants can dry out. This is a problem that has been addressed by the LED grow lights since they can produce less heat. Their energy conversion efficiency keeps them cool, and thus you don’t need these expensive venting systems.
2. CO2 circulation
Carbon dioxide (CO2) is an essential ingredient in the process of photosynthesis. The plant requires it in large amount for its proper development and to produce better yields. The kind of light source that is used will have a lot of impact in the amount of CO2 circulating in the growing space.
For the alternative sources such the HPS, the vent systems including the fans will be taking a lot of useful CO2 from the plants. This will make it difficult for the plant to utilize to the maxim the supplemental carbon dioxide growers. Use of LED grow lights, the fan is set a slower speed, and this will ensure that more CO2 is retained in the growing space. Sometimes, fans may not be needed.
3. Humidity and watering
Plants required balanced humidity to grow healthy and produce better yields. With the broadband light sources, it is difficult to monitor and maintain moisture in the growing space. With the high temperatures associated with these sources, humidity levels are drastically decreased.
The evaporation and evapotranspiration rates are increased, and this will definitely affect the plant negatively. To compensate this loss of water, the grower will have to do a lot watering. With these LED grow lights, less heat is emitted, and this makes it easier to control humidity in the growing space. Less water is lost via evaporation, and thus less watering is required.
4. Light intensity
The intensity of light provided to the plant plays a huge role in photosynthesis. To get high light intensity, it means that you have to install more lights in the room. But this would not work with the alternative sources- the more lights you install, the more heated the growing space got and the high the possibility of the plant drying up or burning.
But with these LED grow lights, it possible to increase the light intensity since you can install as many lights as you wish. There will be no significant heat addition in the room and thus no danger of burning your plants.
5. Increased lifetime
Compared to the alternative light sources such as HPS, these LED grow lights have a longer lifespan. One of the main problems with the HPS lights is blowing up regularly, and the cost of maintenance can be very high. Once you have installed the system, you can rest assured to enjoy their services for a long time.
Their useful life is a very long and they can last for up to 100,000 hours. They do not just suddenly stop working but dims slowly, and thus you will easily notice when their life is coming to an end. They require minimum or zero maintenance, and this will definitely save you plenty of money.
6. Huge energy saving
Compared to their alternatives, these lights consume a small amount of energy. When their efficiency is compared with the HPS, it shows that they decrease energy consumption by 40 % to 75%. Most of the energy in the HPS is lost as heat due to poor efficiency. That’s why your energy bills are will always remain high with most of it being a total waste. By installing these lights, you energy bills will be sliced by more than 60 percent. These lights will save you a lot of money by improving the efficiency of your lighting system.
