There was a long debate over this topic a few years ago, but now things are settled. Every grower knows that the LED lighting system is the best approach for indoor plants growing. There are many benefits of growing plants with artificial lights, such as efficiency, profitability, intensity, and effectiveness. In this article, we will discuss are LED grow lights worth it?
What is LED Grow Light?
An artificial light source that is used to meet the lighting conditions required by plants for photosynthesis is called LED grow light. It is a new addition to the lighting system, but it is changing the way of indoor plants growing. LED grow lights are used as a replacement of the sun for indoor plants and allow plants to nourish and grow normally. These lights are highly directional and can be used in tight areas.
Functions of LED Grow Lights
LED grow lights can be used for
- Strengthening roots
- Promoting fruit ripening and color
- Adjusting flowering date and color
- Improving taste and quality.
What Are the Effects of the Spectrum Range on Plant Physiology?
(Granture GTBar-2 LED Grow Light Bars Spectrum)
Different spectrum ranges will have different effects on plant physiology.
It is already ultraviolet light and can be used for repressive growth of all kinds of plants, animals, and fungi. This kind of wavelength has little effect on physiological and morphology processes.
This wavelength belongs to far-ultraviolet light. It has no direct effect on plant growth, so it doesn’t damage plants. It absorbs the chlorophyll and affects photoperiod effects. As a result, it prevents stem elongation.
- 400~520nm (Blue)
This kind of wavelength develops the roots and stems of the plants. Moreover, they have the highest absorption ratio of carotenoid and chlorophyll. These wavelengths have a great impact on photosynthesis.
- 520~610nm (Green)
The green plants are pushed repulsively, and the absorption rate is not high.
- 610~720nm (Red)
This wavelength significantly affects the plant’s growth rate and photosynthesis. However, the chlorophyll absorption rate of plants isn’t too high.
These kinds of wavelengths are infrared and have low absorption rates. These wavelengths can stimulate flowering and seed germination.
This wavelength is very much close to laser light, where light is converted into heat.
Desired LED light spectrum can promote plant growth, prolong the flowering period, and finally improve the taste and quality of flowers.
Advantages of LED Grow Lights
There are substantial advantages of using LED grow lights. A grower can enjoy some excellent benefits by using LED lighting. Some major advantages of LED grow lights are:
LED grow lights are more efficient than HID lighting system. It means that LED lights will produce more light intensity. Moreover, they can save up to 70% energy.
- Lower Temperatures
HID bulbs become extremely hot, and this heat can be damaging for plants. Moreover, when HID bulbs are used in adjacent spaces, they can even become a fire hazard. On the other hand, LED lights have a cooler temperature.
- Less Bulk
It is another significant advantage of LED grow lights. If you are growing plants in closed spaces or smaller areas, you can use LED lights because they can easily fit into tight areas. LED lights have cooler temperatures so that you can use them in closed spaces without fear of burn. Keep your plants at some distance from LED lights. It is suggested to keep them 12 to 18 inches apart.
- Full Spectrum
LED grow lights provide a huge spectrum of energy. You can choose a lighting system that is suitable for the type of crop you want to grow.
LED grow lights have a potentially longer lifespan than HPS. Typically, these lights last for more than 50000 hours. On the other hand, HID lights just last up to 10000 or a maximum of 18000 hours. When we talk about the lighting system’s lifespan, there is no competition between LED and HID lights.
- Save Money
Everybody wants to save money, and LED lights can help you save money. Governments are encouraging growers to invest in energy and cost-efficient lighting systems. Check this link you to get more info on the 179D Federal Tax Deduction for Lighting.
Are LED grow lights worth it? After looking at all the advantages, yes, LED grow lights are worth it.
Benefits That You Can Get by Using LED Grow Lights
- At night, they can significantly control the light required by plants. Moreover, they can extend the light also.
- You can extend the effective lighting time at any time of the day.
- In the greenhouse, they can replace the natural light and enhance plant growth.
- It increases yield by shortening the plant’s growth stage.
Disadvantages of LED Grow Lights
Undoubtedly, LED grow lights are exceptional, but before purchasing them, look at some of the disadvantages of LED grow lights.
- Blue Light
LED grow lights have blue light, which is good for plants but bad for humans. The blue light spectrum is good for plants, especially during the vegetative stage, but long exposure to blue light can be damaging for the eyes.
- Massive Investment Is Required
HID systems have a small initial investment as compared to the LED lighting system. When we talk about the long run, you will be saving a massive amount of money because these lights are efficient.
- No Standard Specifications
Different manufacturers offer different specifications, so growers will have to do more homework. If you don’t do proper research, you might end up buying an incompatible product. So, it can be a problem for growers to choose the best product.
Are LED grow lights worth it?
After witnessing the advantages of LED grow lights, you must have made your mind to invest in LED grow lights. You can replace your existing HID lighting system with LED lights and save energy and cost in the long run. Moreover, you can purchase LED grow lights from us — direct LED grow lights manufacturer to save your investment cost. So if you still asked are LED grow lights worth it? The answer is absolutely YES!
