The Best Full Spectrum LED Grow Lights for Indoor Plant Growth

Many growers might wonder what exactly are full spectrum LED grow lights?

Full spectrum grow lights have the unique ability to mimic the sun’s natural UV ray production. For indoor gardeners, these lights are a must-have item to ensure successful plant growth.

The lighting is an excellent long-term investment that pays for itself with reduced energy consumption, prolific plant growth, and a bountiful harvest.

In this article, you'll learn about three of the best full spectrum LED grow light for indoor plant growth and how to choose which one is best for your unique needs.


Best Overall Full Spectrum Grow Light: BESTVA DC Series 2000W

My first choice for the best full spectrum grow light is the BESTVA Newest Version Dual-Chip 2000W LED Grow Light which creates the perfect balance of UV rays for plants from vegetative to flowering. The high lumens output of this light guarantees perfect coverage.

What Exactly are Full Spectrum Grow Lights?

You are probably questioning what sets full spectrum grow lights apart from other forms of lighting. Well, there are two types of light in the world: visible and ultraviolet light.

The visible light you can see and is made up of red, orange, green, yellow, blue, indigo, and violet lights. Many bulb manufacturers focus on creating lights that bestow visible light to make their customers happy, but the sun naturally produces light that you cannot see, which is known as ultraviolet light.

Even though an ultraviolet light is invisible to the naked eye, plants require it to flourish and grow.

Full spectrum increases lights harness the power of ultraviolet rays. Although they are invisible to the naked eye, unlike conventional lights, full spectrum grow lights are a necessity for any indoor grow room.

Reasons to Use Full Spectrum Lighting 

Here are three things that you should know about full spectrum grow lights and why you should use them:

  • Plants grown using full spectrum lights reach much larger sizes and are ready to harvest faster.
  • The lights mimic the sun’s UV rays which not only reach plants easier but also are more readily absorbed by the foliage.
  • Unlike other types of grow lights, full spectrum lighting supplies the same power as the sun.

The Main Drawback of Full Spectrum Grow Lights

The only significant drawback to using full spectrum grow lights is the initial investment is expensive when compared with other lighting options. Although it might be costlier, the lights still are the preferred choice by most indoor gardeners.

Control of the Indoor Growing Environment

With an indoor grow system, you control your growing environment, so you are never tied to the seasons.

You can maintain a growth cycle throughout the year with lights. Lighting lets you obtain a more bountiful harvest that often has great colors and flavors than outdoor growing.

Understanding Full Spectrum Lighting

The words ‘full spectrum’ refers to the grow light’s wavelength which is the color of light that a plant needs to photosynthesize successfully. Photosynthesis is the process that a plant uses to convert light into fuel for growth.

Plants are all different, so full spectrum lighting supplies wavelengths that range between 390 to 700 nano-moles.

The Light Spectra

There are two light spectra that you should familiarize yourself with:

  • The Absorption Spectrum: A plant can easily absorb and use these light wavelengths.
  • The Action Spectrum: This spectrum is extremely effective for a plant’s ability to photosynthesis and helps to drive the plant’s abilities.

A full spectrum grow light covers all the light spectra that a plant needs for growth. The lights can cover the absorption spectrum and control the ratio of wavelengths in the action spectrum. The rays produced are all the light that your plant needs to flourish.

One of the critical benefits of full spectrum lighting is that it produces only the types of light that your plants will use to grow and wastes no energy-generating useless forms of view, so you'll conserve money on your energy bill.

The Perfect Spectrum

Many growers want to obtain the ‘perfect’ spectrum of light wavelengths for their plants, but this notion does not exist.

A full spectrum light offers all the main bands of color in the PAR (photosynthetically active radiation) spectrum. These are the wavelengths between 390 to 700nm. However, the exact wavelength does differ from manufacturer to manufacturer. Also, the type of LED’s has an impact. Even the way that you set the light in your grow room will matter.

Some manufacturers also add infrared and ultraviolet wavelengths to their lighting. Also, some lights have been tailored for a full growth cycle, and others offer only during a plant’s vegetative growth or flowering state.

Things to Consider When Purchasing a Full Spectrum Light

There a few things that you should take into consideration before choosing full spectrum lighting.

Cost: Undoubtedly, full spectrum LED grow lights are an expensive investment. The setup cost is typically far higher than standard HPS or HID setups. However, over time, you'll save money because the efficiency of LEDs far exceeds HID lighting.

Also, the average lifespan of an HPS bulb is only about 10,000 hours, but the lifespan of an LED is about 50,000 hours. You'll be able to run LED lights for at least 15 years before you must change lights.

Size: HID and CFL lighting systems are bulky. However, full spectrum pictures are small and modular. They do not need reflectors or large ballasts which makes them a perfect choice for a small grow room or tent.

Heat: Grow lights increase the temperature in your grow room but full spectrum LED lights do not produce excessive heat. The lack of heat emitted by the lighting is ideal if you're growing in a warmer climate
