If you are looking to make an educated decision on purchasing the best LED grow lights for your cannabis growing needs, you have come to the right spot. Check out the table below, or scroll down for more in-depth reviews on each grow light.
There are a variety of elements you must take into consideration when picking the most effective light for your grow room. First of all, you need a light with enough power to reach everything you want to grow. Lights will be different depending on whether your weed grows in one place, or if you have a specific area where you grow seedlings and clones.
If you want to use lights for growing veg, flowers, and weed, then you need to decide whether you want an all-purpose light.
Replacing bulbs is not something you need to be concerned about. You also don’t need to think about bulbs becoming too hot – HID and HPS lights had those issues. But they won’t be a problem with LEDs.
We’re about to take a look at the details involved in the best LED lights. This will help you decide which light would be best suited to the space where you grow weed.
Tips For Picking The Correct Grow Light
The following list gives you the 4 most crucial aspects you need to think about when choosing your LED grow light:
–Knowing the size of the area that needs to be covered is required to know the amount of LED lights you need. You’ll also know which ones suit your growing space to be the most effective.
– For full growth cycles, a full-spectrum LED light would be needed to help in all growing stages.
– Bigger angles mean greater coverage. Smaller angles lead to light being more direct.
– Determine what you NEED first. Then think about how much money you want to
Why Full-Spectrum LED Grow Lights Are The Best
Many people believe fluorescent lights are the best to grow indoor weed gardens, but full-spectrum LEDs are proving to be superior. They’re a fairly new product, so not all growers are familiar with how it works and why it’s the best option.
One of the main benefits is that they imitate real sunlight.
And there are a ton of other great reasons, including the following:
- Support high yields
- Cost effective
- Extra fans not required
- No ballast needed
- Don’t need to replace lamps
Any other systems on the market are simply outdated now. Full-spectrum LED grow lights are the way forward.
Useful Gadgets For Your Grow Room
Sunglasses – You usually wear them to protect your eyes from the sun’s UV rays. And you need to do the same indoors when using a full-spectrum LED light. It imitates real sunlight, so the same rules apply.
Nutrients – Plants need nutrients to grow better. It also affects the flavor, so think carefully about the nutrients you provide them.
Grow Tent – This makes controlling the climate for weed much easier. The plants can be shielded from light sources when they need complete darkness. It’s also a great way to keep yourself protected from the light.
Light Meter – They’re not just for advanced growers. Get ahead of the game and start using one, even if you don’t consider yourself advanced yet.

FAQ On LED Grow Lights
Worth a read if you’re new to growing or just want to ensure you’re doing things right!
What is an LED Grow Light?
- LED stands for light emitting diode.
- Grow refers to the light assisting plant growth indoors.
- Light is the mimicking of sunlight to provide energy for plants to grow.
LED grow lights offer a number of wavelengths, some of which you can see and other that you cannot. These include both UV and IR rays that have massive impacts of growth.
How LED Lights Grow Plants
It’s hard to imagine that these small lights can create so much growth among your plants without using any actual sunlight.
Did you know plants absorb more blue light than any other color? That’s why UV rays are always present in LED lights. They help plants grow incredibly well! The equally important infrared rays are used to stimulate the blooming of plants.
Depending on your model and growing area, the wavelengths can be adjusted. For those wanting to grow plants in the veg stage, UV rays are best by boosting cell division when rays are absorbed. This results in more yield and quicker growth!
When it comes to growing plants in the flowering stage, it is best to use LED lights that are which use IR (infrared) rays. This ensures that the buds can absorb the rays to cause faster blooming.
So those of you looking to pick an LED grow light, we recommend going for on that has a variety of wavelength options on offer. It ensures you can adjust the settings more precisely to the different stage of your plant growth.
Things that can affect the growth of plants include:
- Amount of light
- Type of light emitted
- Types of plants
- Lumen per area
- Height between plants
Why You Should Use LED Grow Lights
Prior to LED grow lights, people used fluorescent bulbs and high-pressure sodium lamps. However, these growing methods negatively affected growers who had small growing areas. These older lights required more space to set up. To make matters worse, there was a ton of heat being produced meaning that a ventilation system also needed to be equipped. Everything involved in this process made it way too difficult for new and small-scale growers to get started.
Some of the biggest benefits of using LED grow lights include the following:
- Easy Set Up And Small – LED lights are compact and you don’t need to be an expert to install them. All you need is a suitable place to hang the item above the plants at a certain distance.
- No Ventilation System Needed – These lights let off a minimal amount of heat and keep themselves cool with large fans.
- Better Coverage – LED lights are small meaning they can be set up adjacently which means a larger area can be covered.
- Easily Adjustable – You can alter wavelengths and modes depending on the specific stages of growth.
LED grow lights don’t require much space at all, their bulbs don’t need replacing, there are to ballasts to deal with, and they take just half of the power to run continuously.
All of these benefits combined have made us huge supporters of LED lights. You can get great results, for a cheaper price, and less work!
What’s The Ideal Amount Of Watts?
To know the amount of watts you need to effectively grow, measure the area and the quantity of plants you want in that space.
As a general guide, 1 square foot includes 1 plant in that area. In this instance, there should be 25 watts for each plant in each square foot. If you’re fitting two plants into one square foot, the wattage would simply double to 50 watts per square foot.
So if we go by these examples, and you have a 250 watt LED grow light, 8-10 plants can grow underneath it for optimal growth.
Whether you’re a new grower, or an advanced one, we hope this guide for the best LED grow lights has been helpful!
