What Are LED Strip Lights?

LED strip lights are light-emitting diode (LED) lighting. They come in long, thin strips that can be cut to size and used for various purposes. One popular use for LED lights is under-cabinet lighting in kitchens. But you can also use them for accent lighting, task lighting, and, of course, plant lighting.

Strip lights come in various colors, but the most popular for plant growth are white and blue LED lights. Blue LED lights are thought to promote the vegetative growth of indoor plants, while white LED lights promote flowering and fruiting. So if you're looking to grow plants that produce flowers or fruit, white LED lights are a good option.

How to Use LED Strip Lights for Plant Growth

Using LED lights for plant growth is pretty simple. You'll need to attach the LED lights to a power source and place them near your plants. If you're using them as supplemental light, you'll want to place them above or beside your plants. And if you're using them as the sole source of light, you'll want to place them directly under your plants.

Do not place the LED lights too close to your plants. The last thing you want is to burn your plants with the heat from the LEDs. So start by placing the strip lights a few inches away from your plants and adjust as needed.

You can also buy special grow light hangers that will allow you to suspend your LED lights above your plants. It is a good option if you're using them as supplemental light, as it will allow the light to reach all parts of your plants evenly.

Choosing the Right LED Strip Lights for Plant Growth

When choosing LED strip lights for plant growth, there are a few things to consider.

Choose an LED Light that Emits the Right Color For Your Plants

Blue LED lights, just like natural light, are great for vegetative growth, while white LED lights are great for flowering and fruiting.

Different Led stripes lights

The Right Wattage

The higher the wattage, the brighter the light. The wattage determines how much power the light consumes. The higher the wattage, the more power the light consumes.

The Right Beam Angle

The beam angle is the width of the light beam emitted by the LED light. A wider beam angle will spread the light over a larger area, while a narrower beam angle will focus the light on a smaller area.

A High lm/W Ratio

It measures how much light the LED light emits per watt of power. A higher lm/W ratio means more light and less power consumption.


Lumens measure the amount of light that is emitted from the led grow light strips. The higher the lumens, the brighter the light.

Color Temperature

The color temperature of an LED is measured in Kelvin (K). The lower the Kelvin, the warmer the light. The higher the Kelvin, the cooler the light.

Benefits of Using LED Strip Lights for Plant Growth

There are a few benefits of using LED lights for plant growth.


Strip lights are more energy-efficient than traditional grow lights. They use less power and last longer, so you'll save money in the long run.

Long Lifespan

LED strip lights also have a longer lifespan since they last for 50,000 hours or more, so you won't have to replace them as often.

Low Heat Output

LED strip lights produce very little heat. It means you won't have to worry about burning your plants with the heat from the LEDs

Best LED Light Color For Seedlings & Clone Growth

There are different color lights available in the market, but which one is best for growth of your weed seeds? Will a blue light help your cannabis plants grow faster than white light? The answer to this question is not easy because it all depends on what stage of growth your plant is currently in.

If you start with cannabis seeds or clones, you will want to use a blue light. This light helps the plant to grow strong roots and stalks. It also suppresses the growth of algae.

Red blue LED light strips

The vegetative stage requires either blue light or white light. The light will help your plants grow faster, but it can also stunt their growth if left on for too long. White light is a better option for the vegetative stage because it allows the plant to grow steadily.

The flowering stage requires red light. Red light helps the plant to produce more flowers and fruit.

What is The Best LED Light Spectrum For Cannabis Plants?

The best-LED light spectrum for cannabis plants is full. Full-spectrum LEDs provide a wide range of colors, from red to blue to white. They mimic sunlight, which is ideal for the growth of the plant. The only downside is that they are more expensive than other LEDs.

Types of LED Strip Lights

There are two types of LED strip lights:

Single Color

As the name suggests, single-color LED lights to emit one color of light. They are the most basic and least expensive type of strip lights. Also, single-color LEDs are not as effective for plant growth as full-spectrum LEDs.

Full Spectrum

Full-spectrum LED lights to emit a wide range of colors, from red to blue to white. They mimic sunlight, which is ideal for plant growth. Full-spectrum LEDs are more expensive than single-color LEDs, but they are worth the investment.

LED Strip Lights For Hydroponics

Hydroponics is a method of growing plants in water. The roots of the plants are submerged in a nutrient-rich solution, and the plants are grown under an LED light strip.

Hydroponics is a great option for growing plants because it doesn't require soil, so there's less chance of pests and diseases. Also, hydroponics allows you to control the nutrients to tailor the nutrient solution to your plants' needs.

The best LED lights for hydroponics are full-spectrum LEDs. When growing plants in water, you need to provide them with a wide range of colors, from red to blue to white. Full-spectrum LED lights are the most effective type of LED light for plant growth.

How LED Strip Lights Work?

Strip lights work by emitting light in a specific color spectrum. The LEDs are arranged in a row, and each LED emits a different color of light.

The different colors of led grow lights help the plant to grow in different ways. For example, blue light helps the plant grow strong roots and stalks. Red light produces full-spectrum light for the plant to produce more flowers and fruit.

How Do I Know If a Led Light Is Suitable for Growing Plants?

When choosing an LED light for growing plants, looking for a few key features is important. First, the light should be labeled “full-spectrum” or “plant grow light.” It means that light produces a broad range of wavelengths, including visible and invisible light. Second, the light should be bright enough to support the growth of the plant.

A good rule of thumb is that the light should be at least 500 lumens per square foot of growing space. Finally, the light should have a high red and blue light ratio. Red and blue lights are essential for photosynthesis, so a high ratio of these colors will promote healthy plant growth.

When to Use LED Strip Lights?

You can use the LED spectrum light any day or night. However, they are most effective when used during the vegetative and flowering stages.

The vegetative stage is when the plant is growing leaves and stems. The flowering stage is when the plant produces flowers and fruit.

You also can use LED lights during the vegetative and flowering stages. However, they are most effective when used during the vegetative stage. During the vegetative stage, blue light helps the plant to grow faster. During the flowering stage, red light helps the plant produce more flowers and fruit.

You can use LED strips for as long as you want. However, they are most effective when used for 12-16 hours per day.

In conclusion, LED grow lights are the way of the future. They are more energy-efficient, last longer, and don't emit much heat. It's important for people growing their plants indoors. LEDs will help you save money on your electricity bill, and these savings will offset the additional cost you'll pay for your LED grow lights.

LEDs are also a great way to conserve energy as they use up to 75% less electricity than traditional grow lights like HPS lamps. The only downside of LEDs is that they're not as bright as other types of lighting, so you won't be able to see as well when working in your garden at night or during cloudy days with low light conditions (but this can easily get resolved by getting some additional high-intensity lamps).
