Overview

LED grow lights have plenty to offer in the world of indoor gardening and they are, therefore, worth investing in.

They have been shown to promote plants’ overall growth by ensuring that they get the required light to grow and flourish.

Before the emergence of LED grow lights, keeping indoor plants alive was strenuous for most people. Shifting indoor plants from one point to another or placing them at a certain point that doesn’t suit your aesthetic so that they can get sunlight is generally hectic and annoying.

But not anymore with LED grow light. Thanks to LED technology you can now place your plants where you like irrespective of the lighting situation in your house and let the lights grow and do their thing.
Unlike in the past years, we now have plenty of these devices on the market today from different brands and they are beating the limitation of the traditional grow lights which has been limiting.

According to the president of Florida-based BIOS Lighting Company Sean Tegart, LED grow light technology is rapidly becoming a choice for many indoor plant growers.” This is because, unlike the traditional grow light, LED lights are programmed to deliver different parts of the plant both visible and invisible light spectrum to optimize their growth.

Tegart further notes that “the majority of indoor plant growers are warming up to this technology because the devices can last for about 15-20 years without the need to change the bulbs.”

Top Picks: Best Grow Lights

What is a Grow Light?

LED grow lights have tremendous benefits in the world of indoor gardening. They support the growth of indoor plants from the initial development stages like germination and shooting to flowering, and ensure that they grow and flourish into beautiful healthy plants.

The LED technology increases the indoor plants’ ability to complete photosynthesis and ensure that they grow strong and healthy. It is a targeted approach that ensures that the energy high percentage is not wasted but utilized to support the growth of plants.

Research published by Juseppina Pennisi et al in Frontiers in Plant Science notes that

Unlike traditional grow lights that produce limited light spectrum and excessive heat, LED grow lights are designed in a way that they produce specific light wavelengths that the plants can comfortably absorb.

In a publication in The Journal of Applied Ecology, Xian-Wei Chen, Shi-Qi Liu, Yue Wang, Jing-Kai Liu, and Lei Feng looked into the advantages of using LED light growth over traditional lighting. Compared to traditional lighting, red and blue LED lights appeared the best combination as they increased plant growth, nutritional quality, leaf chlorophyll content, and photosynthetic rate.

Types of Grow Lights

LED grow lights

LED grow lights are energy efficient. They produce lighter but less heat at a lower cost compared to conventional lights.
Since we are referring to lights that will be on for long hours every single day, these attributes are worth considering.
The initial price of LED bulbs may be high but keep in mind that the long-term savings are quite significant. The bulbs can serve you for more than 10 years before you can think of replacing them.

High-intensity discharge lights (HID)

High-intensity discharge (HID) lights are another type of grow light considered powerful for growing indoor plants, especially for large plants or grow spaces.
They are commonly used in controlled environment labs or indoor farms. They produce both full spectrum and bright light than any other grow light device.
They are highly priced because of their extremely powerful nature and they produce a good amount of heat which means you will at some point required to cool the place.

Fluorescent lights

Fluorescent lights are another popular light grow option for people with indoor plants. These types of light grow are affordable and energy efficient but not as efficient as LED lights.
They also provide a great spectrum of light that enhances plant growth and development. However, their output is said to produce excess heat which can lead to plant damage.

Incandescent lights

Incandescent is another type of light grower you can use on your indoor plants. However, they produce much heat and less light meaning that an overheating effect is highly likely to occur. It is, therefore, best used as a supplement for lighting your plant and not for plant growth.

Key Features to Consider When Choosing the Best Grow Lights

If you want to properly raise and care for your indoor plants, the following factors are worth considering when buying a grow light.

Types of Plants

Indoor plants are different so they may vary in terms of treatment. Some may require intensive light while others less light and others may require different colors and so on.
So, before buying a light grow, you should do research first to increase your chances of selecting a lighting grow that will properly care for your plant.

Photosynthetic Photon Flux [PPF] and Photosynthetic Photon Flux Density [PPFD]

When buying an LED light grow device, choose one that can adequately provide maximum benefit to your plant.
Considering a light grow device with PFF and PPFD features is important because it will provide valuable light that will optimize the growth of your indoor plants and ensure survivability.

Micromoles

Micromole is a unit of measurement meant to describe the amount of light that lights up an area for a given period of time.
As far as plants are concerned, micromoles enable us to understand the amount of light that is required for photosynthesis to take place.
However, the requirement may be different depending on the type of plant one has. So, it is important to research and check out how much light that plant in your home requires.
Fortunately, most LED grow lights specify the number of micromoles it is set to produce so that you can decide whether it suits your plant or not.

Heat

Basic indoor plants do not require excess heat for them to grow. In fact, a bulb that produces excess heat may damage the plant.
So, when buying a LED light grow, check out the amount of heat is meant to produce because different bulbs or lighting systems are designed to produce different amounts of heat.
For the safety of your houseplants, we recommend going for one that produces a decent amount of light.

Bulb Sizes and Shapes

LED lights grow bulbs differ in shape and size and so, they cannot fit in one fixture. So, before buying a bulb, verify the size and shape to ensure that it can properly fit in the space.
Note that LED light bulbs are not just ordinary bulbs. Some can be 2-3 feet long so if you don’t have enough space in your home for such lights, then it will be a waste of money to buy them. Choose a size or shape that matches the available space.

How Do Grow Lights Work?

The majority of plants utilize sunlight to grow. Light from sunlight is referred to as white light but technically, it is just a combination of all colors both visible and invisible to us.

So, exactly does light work for plants? Plants need light in order to grow. However, it is worth noting that plants utilize each of the spectrum colors for a specific function.

Though we are able to interpret most of the colors, blue and red are the colors identified as the most important for plants’ successful growth.

The combination of the two LED lights creates a balance in the indoor growing environment to ensure better and healthy growth of plants, a notion that a statement by professor, and researcher Janis T. Ells noted in another content we reviewed for Red Light Therapy Benefits.

Blue lights are crucial for anything to do with the structural aspects of the plant. The blue lights work to make the structural part of the plant healthy and strong.

According to a publication in Molecules Journal, LED light spectrum does affect indoor plants’ growth and development as well as metabolite production. Blue light spectrum was found to support the plant’s leaf photosynthetic process, stomata opening, morphogenesis, and phototropism.

Red lights, on the other hand, are known to support the plant’s initial phases of development including flowering.

It helps the plant to flower and fruit and has also been found to enhance plant’s photosynthesis and promote the overall growth of plants.

According to a research study published in Plants Journal, red light was found to enhance leaf photosynthesis leading to the growth of new leaves, new shoot length, leaf thickness as well as polyphenols.

Benefits of Grow Lights

  • Promote plant growth: Grow lights have hues great for optimizing survivability and photosynthesis for the successful growth of your indoor plants.
  • Energy efficient: Compared to traditional lighting, growth lights are 30-50% more efficient. They provide minimal light which reduces heat-damage-related risks to your plants and also prevents energy wastage.
  • Spectrum timing and dimming control: Grow lights are designed with spectrum timing and dimming control fixtures. The intensity setting enables you to fine-tune the lighting as per the specific plant’s requirements. With the flexibility feature, you can optimize how the energy is used to ensure that your indoor plants get the right amount of light at different developmental stages.
  • Easy to plug and set up: Grow lights are hassle-free to use. Plugging in and setting up the light grow is fast and simple.
  • Safe to operate: Grow lights are safe to operate as they contain no mercury.
  • Long bulb life: Grow light bulbs are designed to last long. They can provide light to your plants for about 50,000-100,000 hours without needing a replacement. If translated to years, the bulb is set to serve you between 5-10+ years (of non-stop use).

Frequently Asked Questions

Q: How Long Should I Leave May Grow Lights On Each Day?

Q: What Number of Watts of Grow Lights Do Need Per Square Foot of Grow Space?

A: The standard watts of the actual watts per square foot of grow space is between 30-40 watts. However, depending on efficiency, some LED growth may require less while others more of this.
To ensure optimal results from LED growth, it would be best if you followed the manufacturer’s recommended watts because LED units are not the same as they are designed to function differently.

Again, you should not use wattage to determine how powerful an LED grow light is. You should also consider other factors which are equally important like footprint and PPFD uniformity.

Q: How far away should I set up my Grow Light from the plant canopy?

A: There is no specific distance. How far you should set up your grow light from the plant canopy should be guided by various factors such as light shape, beam angle, coverage area, brand, etc.
All these factors do affect the photosynthetic active radiation meant to contact your indoor plant leaves.
The best thing to do in this case is to follow the recommendations of the manufacturer because coming from different brands, the grow lights will slightly vary in some way.
But in general, the typical distance of most grow lights is usually 18̎-36̎. If it is a flowering plant 18̎ would be ideal and 24̎ for veg.

Conclusion

As many people turn to indoor gardening, there is a growing need for indoor artificial lighting. Luckily, many LED manufacturing companies are responding to the demand and are now producing many LED lights to match indoor gardeners’ needs.

Using LED lights to grow over traditional lighting has proven to be effective. The LEDs have been shown to support effective plant growth, development, and nourishment with limited risk-related damages.
Notable also, by utilizing LED technology to grow indoor plants, they stand a chance of experiencing many benefits like metal halide, high-pressure sodium, and fluorescents that traditional grow lighting does not offer.

Most of the devices are cost-effective and easy to use, meaning that they will save you money and time.
