LED grow lights are better for plants for several reasons. LEDs are cooler to operate, which means they consume less energy. Some models even come with built-in cooling fans. These fans can improve the overall energy efficiency of the grow light and cut operating costs. Cooling fans are also beneficial to the longevity of LEDs, as they degrade more quickly in hotter temperatures. So, while choosing LED grow lights, you should choose one that has built-in cooling fans.
PPFD
While PPFD stands for power per foot of light, the PPFD value depends on the distance from the LEDs to the plant, as well as the amount of PPF lost to the canopy. Generally, PPFD LED Grow Lights are better for plants when they provide higher levels of light over the leaves. The difference between PPFD and PAR is often quite significant, and is the basis for a wide range of LED Grow Lights.
The PAR spectrum contains infrared light, which can be detrimental to plants. LED Grow Lights have few infrared diodes, which are responsible for regulating plant growth phases. Proper infrared light promotes full stem growth and proper node spacing, resulting in higher yields. In general, LED Grow Lights are better for plants when they contain the correct PPFD for their specific growth stages.
Energy efficiency
Despite their high-end features, LED grow lights are not without disadvantages. One of the main disadvantages of HPS lamps is the amount of heat they produce. The latter is more expensive in the long run and is bulky, so they are not suited for vertical farms. LEDs are more energy-efficient than HPS and CFLs, as they spend most of their energy on producing light instead of generating heat. Hence, you can use LED grow lights in greenhouses to speed up the production and harvest.
With the help of LEDs, you can control the wavelengths of light to maximize plant development and quality. For instance, blue light enhances chlorophyll production in plants, while red light promotes flowering. Depending on the type of plant you have, you may use blue or red light. This will help the plant grow and flower better. In the later stages, however, it can be detrimental. By reducing the heat produced by the light source, you can place the fixture closer to the plant, enhancing the growth process.
Color spectrum
When you’re buying a plant growing light, you should look at the color spectrum of the product. The spectrum of light produced by LEDs or bulbs should be able to mimic natural sunlight. Often, indoor growers recommend using different spectrums for different stages of plant growth. However, that is not always the case. In some cases, the plants may be better off with a light that is blue or green.
Unlike traditional grow lights, LEDs have an almost infinite spectrum of emission. White LED grow lights produce the full spectrum of light that mimics the spectrum produced by natural sunlight. The white spectrum contains red, blue, and green light. Different kinds of light are rated according to their color temperature, and a cool spectrum will produce more red and blue photons. The spectrum of an LED grow light should mimic the natural light of plants and avoid the harmful UV rays.
Fanless design
Whether fanless LED grow lights are better for your plants depends on your personal preferences. Some growers prefer fan-free lights for environmental reasons, while others prefer a quieter operation. In either case, both models have some common traits. The primary differences are the size, coverage area, and temperature. If you’re trying to grow your plants in a small room, a fanless LED grow light is likely to be better for your plants.
Wideband LED grow lights produce a more even light spectrum. They are much more effective at reaching the plants’ “supercharger” color region. These lights are relatively inexpensive and replaceable, with industry-first linear lenses. They produce an even distribution of light and a large sweet spot. This light type is also much more energy-efficient than older models, which require expensive fans. The best-quality LED grow light is fanless.
Cost
When it comes to growing plants indoors, LED grow lights are the way to go. These modern lights use two types of semiconductor materials to produce light: positively charged protons and negatively charged holes. When these materials collide, energy is released in the form of a photon. The wavelength and quantity of energy will determine the color of the light. LEDs are particularly known for producing full-spectrum light. This light is more efficient and practical than other types of lighting. You could also buy artificial plants if you don’t want to worry about maintaining them.
When considering the cost of LED grow lights, you must consider that they require 30 to 40 watts per square foot. A standard size light can support up to two plants or four plants. In other words, a 600 watt grow light will cost you about $40 a month. Although the cost of electricity for LED grow lights is lower than other types of lights, you will still have to pay a large power bill every month.
