As the world becomes increasingly urbanized, people are turning to indoor gardening as a way to bring some greenery into their lives. One of the most popular methods of indoor gardening is using LED grow lights, which provide plants with the light they need to photosynthesize and grow. But what plants will grow under LED lights? In this article, we’ll explore the world of LED grow lights and the plants that thrive under them.
Understanding LED Grow Lights
Before we dive into the plants that will grow under LED lights, it’s essential to understand how these lights work. LED grow lights are designed to mimic the spectrum of natural sunlight, providing plants with the light they need to grow. They are energy-efficient, produce minimal heat, and can be tailored to specific plant species.
LED grow lights typically consist of a combination of different colored LEDs, each emitting a specific wavelength of light. The most common colors used in LED grow lights are:
- Blue (400-500nm): promotes leaf growth and development
- Red (600-700nm): promotes root growth and flowering
- Green (500-600nm): provides a balanced spectrum for overall growth
Types of LED Grow Lights
There are several types of LED grow lights available, each with its own unique characteristics. Some of the most common types include:
- Panel-style LED grow lights: These lights consist of a flat panel of LEDs and are often used for small to medium-sized grows.
- Strip-style LED grow lights: These lights consist of a strip of LEDs and are often used for larger grows or for providing supplemental lighting.
- Cob-style LED grow lights: These lights use a single, high-powered LED and are often used for larger grows or for providing intense lighting.
Plants That Will Grow Under LED Lights
Now that we’ve covered the basics of LED grow lights, let’s take a look at some of the plants that will grow under them. Keep in mind that almost any plant can be grown under LED lights, but some plants are more suited to this type of lighting than others.

What are the benefits of using LED lights for indoor gardening?
Using LED lights for indoor gardening offers several benefits. One of the main advantages is that they produce minimal heat, which reduces the risk of burning plants and allows for closer placement to the plants. This also means that LED lights are energy-efficient and can help reduce electricity costs.
Additionally, LED lights can be tailored to specific wavelengths and spectrums, which can enhance plant growth and development. They are also long-lasting and can be used for up to 50,000 hours or more, making them a cost-effective option in the long run. This makes LED lights an ideal choice for indoor gardening, especially for those who want to create a sustainable and efficient growing environment.
What types of plants can grow under LED lights?
A wide variety of plants can grow under LED lights, including leafy greens, herbs, and flowering plants. Some popular options include lettuce, kale, spinach, basil, and tomatoes. These plants are ideal for indoor gardening because they are relatively easy to grow and can thrive in a controlled environment.
Other plants that can grow under LED lights include microgreens, which are young, nutrient-dense versions of leafy greens and other vegetables. These plants are perfect for indoor gardening because they require minimal space and can be harvested in as little as 7-10 days. With the right LED lighting, you can grow a wide range of plants indoors, from simple herbs to complex flowering plants.
How far should LED lights be placed from plants?
The distance between LED lights and plants depends on the type of plant and the intensity of the light. Generally, LED lights should be placed 6-12 inches above the plants to provide optimal light coverage. However, some plants may require more or less light, so it’s essential to research the specific needs of your plants.
It’s also important to note that LED lights can be adjusted to different heights and angles to provide the best light coverage for your plants. Some LED grow lights come with adjustable arms or hangers, which allow you to customize the light placement to meet the needs of your plants. By adjusting the distance and angle of the LED lights, you can create an optimal growing environment for your plants.
How long should LED lights be left on for indoor gardening?
The duration of LED light exposure for indoor gardening depends on the type of plant and its growth stage. Generally, plants require 12-14 hours of light per day, but some plants may require more or less light. For example, seedlings may require 18-20 hours of light per day, while mature plants may require 10-12 hours.
It’s also essential to provide plants with a period of darkness to simulate a natural day-night cycle. This allows plants to rest and recover from the light exposure, which can help promote healthy growth and development. By adjusting the duration and timing of LED light exposure, you can create a natural and optimal growing environment for your plants.
Can LED lights be used for seed starting?
Yes, LED lights can be used for seed starting. In fact, LED lights are an ideal choice for seed starting because they provide a gentle and consistent light that promotes healthy germination and growth. LED lights can be placed close to the seeds, usually 2-4 inches above, to provide optimal light coverage.
When using LED lights for seed starting, it’s essential to choose a light with a balanced spectrum that includes blue, red, and green wavelengths. This will provide the seeds with the necessary light for germination and growth. Additionally, make sure to keep the LED lights at a consistent temperature and humidity level to promote healthy seed growth.
Are LED lights more expensive than other types of grow lights?
While LED lights may be more expensive than other types of grow lights upfront, they can be more cost-effective in the long run. LED lights are energy-efficient and can last up to 50,000 hours or more, which means they require less maintenance and replacement.
Additionally, LED lights can be tailored to specific wavelengths and spectrums, which can enhance plant growth and development. This can lead to faster growth rates and higher yields, which can offset the initial cost of the LED lights. When considering the cost of LED lights, it’s essential to factor in the long-term benefits and savings they can provide.
Can LED lights be used in conjunction with other types of grow lights?
Yes, LED lights can be used in conjunction with other types of grow lights. In fact, combining LED lights with other types of grow lights can provide a more comprehensive and balanced light spectrum for plants. For example, combining LED lights with fluorescent lights can provide a broader spectrum of light that promotes healthy growth and development.
When using LED lights in conjunction with other types of grow lights, it’s essential to consider the specific needs of your plants and adjust the light placement and duration accordingly. By combining different types of grow lights, you can create a customized growing environment that meets the unique needs of your plants.
