Growing indoors gives you several advantages over outdoor gardening. The most obvious is that you can better control the temperature. Most plants will have a narrow range of temperatures under which they will produce blooms or fruit. Another factor you can control in an indoor growing environment is the humidity level.

The Benefits of UV Light for Indoor Plant Growth
Many LED lighting suppliers will say that full-spectrum LED grow lights are the best option for growing plants because they mimic the natural light from the sun. The argument goes:. Why would we want to change what mother nature knows is best? Well, we want to let you know that there is no such thing as a full-spectrum LED grow light. A full-spectrum LED grow light is simply a marketing term that implies that your grow light closely resembles light from the sun.
The full-spectrum LED grow light is the newest evolution of an already confusing term. Originally, full-spectrum light described the only real full-spectrum light source, the sun. Over time, the term began to take on other characteristics of sunlight. Humans perceive colors more accurately under light sources with a CRI over 90, much like how we see colors in our natural world under daylight.
This was a beneficial feature for human environments such as offices, outdoor spaces, and others. With the advent of horticultural lighting, companies once again began to borrow the term.
Only this time, they claimed that full-spectrum LEDs could reproduce the effects of sunlight for plants. Thus, the full-spectrum LED grow light was born. Unfortunately, lighting for plants is not quite that simple. There are many issues with the concept of full-spectrum LED grow lights. This rhetoric may have made sense for lighting designers interested in selling lights so humans could see, but plants require light to feed, grow, and live.
A major problem with many full spectrum LED grow lights is that they are designed to give the appearance of daylight without being custom-tailored for rigorous plant growth. Plants photosynthesize electromagnetic radiation in the to nanometer range, known as Photosynthetically Active Radiation or PAR. Our understanding of plant photobiology has come a long way. We understand much more about plants than to be using human lighting metrics to design our grow lights.
Our goal as growers is to improve the lighting characteristics most important for plant growth. This means not only getting enough PAR light, but also the right mix of light spectra, which brings us to problem 2. In Figure 3 above , we see a standard k full-spectrum LED curve.
This LED has been optimized for its warm visual appeal by stacking most of its energy in the orange-to-red wavebands. This spectrum is optimized for the visual spectrum between to nanometers.
Emphasis has also been placed on light around nanometers because this is where our eyes are most sensitive. The thinking behind many full spectrum LED grow lights on the market is that by creating a spectral distribution similar to sunlight, your plants will grow well. A decent theory, except that full spectrum grow lights are not actually similar to the sun. Sunlight itself is complex, and many scientists are still working to understand it today.
Although PAR is the most important light for photosynthesis, plants still respond to radiation outside of the PAR spectrum. For instance, UV light elicits protective compounds in plants similar to the way humans become tanned in the presence of UV. To create a light source that elicits plant response the same way the sun does would be too costly and downright impossible given current grow light technology. Nor would you want to create such a grow light, which takes us to problem 3.
In the graphic above, you can see how sunlight spectra change throughout the day or in different weather conditions. If you hang your full spectrum grow lights in a greenhouse, you will still reap the benefits and disadvantages of this natural process from the sun.
But if you take those same full-spectrum lights and hang them indoors, they will not behave like the sun. Photomorphogenic responses by plants are co-regulated, which means that certain expressions of the plant may turn on or off based on the amount of light within one waveband relative to another.
Photosynthesis depends upon the absorption of light by photoreceptors and pigments in the leaves of plants. The most well-known of these pigments is chlorophyll-a, but there are many accessory pigments that also contribute to photosynthesis. The relative light absorption of chlorophyll pigments as shown in the graph to the right is one of the reasons why red light has become popular among LED grow lights.
Not all PAR light contributes to photosynthesis equally, though we now understand that other wavebands of light such as green, do play an important role in this process. For instance, higher ratios of blue light can induce more robust root growth, more favorable plant biochemistry, and a hardier structure. But these effects may not be as pronounced when more red light is introduced.
Thus, the ever-changing spectrum of the sun is constantly signaling to plants to change their form and structure based on the natural conditions of the environment.
Plants only require light in the to nanometer range to photosynthesize. The answer is both simple and quite complex. Plants only require PAR light for photosynthesis. It should be clear by now that there are no real standards around full spectrum LED grow lights. Full-spectrum is simply a term used to sell you a simple idea.
Luckily, there are many grow lights available with designs intended to do just that. These grow lights most often have a pink or purplish hue since they are optimized for the blue and red PAR wavebands. These types of pink grow lights have been popular since the early days of LEDs for horticulture. In greenhouse environments a narrow spectrum is almost always desired. The sun already fills out a full spectrum, so it makes sense to put most of your energy into wavelengths that are most optimal for photosynthesis.
Also, because of the added efficiency of red diodes versus other colors, you will get more bang for your buck when it comes to energy efficiency. These lights are white in appearance, though there are no actual white wavelengths. The white hue is a mix of blue, red, and green wavebands. Our broad-spectrum has been enriched with red and blue peaks to drive robust photosynthesis and plant structure while emphasizing the green waveband to be versatile with any crop type or cultivation environment.
Recommended for indoor environments, except in specialized cases where narrow-band lighting is preferred. These modern LED grow lights allow for precision control of your plants.

There, we said it. Figure 1 — In recent years, full spectrum is a term that has been used to refer to light between the UV and infrared wavebands as seen in the graphic above.
Figure 2 — One of the reasons that lighting engineers could achieve a high CRI was by creating a smoother and more continuous spectral distribution curve SDC reminiscent of daylight. Still, most full-spectrum lighting companies build fixtures with this visual appeal in mind. Figure 4 — The image above shows the spectrum of solar radiation at sea level red and out of the atmosphere yellow. Author — Nick84 Sunlight itself is complex, and many scientists are still working to understand it today.

Full Spectrum LED Grow Lights: The Truth You Need to Know
In actual fact, the opposite is true! At the beginning of my indoor plant journey, I really had no idea about plants. I just found one that caught my eye and stuck it in the corner. Giving plants as much light as possible can go against our plans to spruce up that bare corner or that dark room that needs some life added. If grow lights are new to you, read on to learn specific advice on how to use grow lights for indoor plants.
plant's growth stage. With a higher light output to help growth and a pleasing light quality, our energy efficient LED Grow Lights create an optimal indoor.
Succulent Grow Light Recommendations
LED lights are more efficient than traditional fluorescent and incandescent lights. However, as the chart below demonstrates, the complete spectrum of light is far greater than just the visible light spectrum. IR light can only be seen with special equipment, like night-vision goggles. These include X rays, Microwaves and even Radio Waves. One of the most important things to understand is that scientists have demonstrated over and over again that plants only absorb visible light for photosynthesis. Plants do react to other forms of light like UV, but that reaction is typically negative. Lumens are used to measure the brightness of a lamp to the human eye. But plants and people see light differently.
What Plants Will Grow Under a White and Blue LED?
Light is the single most important variable with respect to plant growth and development and is often the most limiting factor. Therefore, the use of grow lights in commercial greenhouses is beneficial for plants and growers. The reason for using grow lights varies and includes increasing light levels for plant photosynthesis or altering photoperiod. The duration of light a plant perceives is photoperiod.

14 Best Grow Lights to Help Your Indoor Plants Thrive
Grow lights are expensive. Regular light bulbs are not. And when it comes to LEDs, you want to be careful. Some regular LED lights can work just fine as grow lights, but many are not suitable—see the LED section below for more. New leaves will often be larger in size and the leaves on the inner part of the plant may start to turn yellow.
Can I use normal LED Lights to Grow Plants Indoors
LED lights last for thousands of hours and have better energy efficiency compared to incandescent bulbs. That makes them a great choice for household and commercial use. Is there any difference between these and traditional LEDs? We did lots of research to bring you the answer. Standard LED lights only provide illumination while LED grow lights have a wider spectrum of both blue and red light that promote vegetative growth and flowering, respectively. To discuss the differences between LED lights and LED grow lights, we first have to explain both light sources in depth. Then we can compare them.
Indoor grow lights can also create these rays artificially, making it possible for growers to give their indoor plants the same benefits as those grown.
How to Choose the Best Plant Grow Lights for Your Indoor Garden
Without using grow lights, maintaining an indoor garden can be tricky. Even if you have plenty of windows, certain species still may not receive the light they need to flourish. Window panes dilute natural sunlight and moving them even a short distance from the glass amplifies that dilution. There are many species of plants that are very needy when it comes to the sun.
Benefits of LED Lighting for Indoor Plants: Red vs. Blue
Today, you can use grow lights to help cultivate many kinds of plants at all year long, no matter where you happen to live. Grow lights are designed to be a sunlight substitute. They stimulate the photosynthesis process within plants by providing them with the right color spectrum. You can grow all your favorite herbs, fruits, and vegetables year-round by using the correct bulb or fixture.
