When a marijuana plant grows wild in nature, it survives because it has everything that it needs. Sunlight, air, and rain/groundwater is essential, and so is the natural cycle of the sun and the changes that happen to the surrounding environment. However, when it comes to professionally growing a marijuana plant indoors, growers need to pay attention to a lot of factors, which includes finding the right kind of lighting. The right kind of lighting can be achieved by using the best veg lights for growing marijuana. Over the course of this article, we will focus on the 7 best LED veg lights for vegetative growth that will help your marijuana plant stay healthy.

We will also discuss what an LED vegetative grow light is and why it is so useful for growing marijuana. Afterwards, we’ll take a closer look at what the vegetative phase of growth is. Then we’ll examine the 7 best lights for vegging cannabis in detail, along with the pros and cons of each of them. We’ll also take a quick look at our buyer’s guide where you can discover what you need to look for in a grow light before you buy it. Lastly, we’ll answer some of the most frequently asked questions about LED grow lights for vegetative growth. Let us now begin by addressing some basic questions:

WHAT IS A VEGETATIVE LED GROW LIGHT AND WHY IS IT USEFUL?

There are many different kinds of veg lights for weed, but all of them serve the same purpose. They ensure that the marijuana plant that you are growing indoors gets enough light. These grow lights have lights of different wavelengths, which helps them recreate natural sunlight inside a controlled environment. Unlike the natural cycle of the sun, however, you can control exactly how much light you give to your plants and for how long. This is a great feature that allows growers to grow the ‘optimal’ plant that provides high yields at the end of the growing cycle.  

There are a number of different types of grow lights, but LED lights for vegetative growth are usually considered the best option for growers. Other types of LED grow lights for vegetative growth include High-Pressure Sodium grow lights, metal halides, CFL grow lights, and more. However, veg lights for weed are better for a number of reasons. First off, they can last you for close to 100,000 hours or even more. Another great thing about these lights is that they are totally non-toxic and do not carry any chemicals inside them, making them safer to operate and easier to dispose of. However, the biggest benefit of using LED grow lights for vegetative growth is that they have a much cheaper operating cost when you compare them to other traditional grow lights. 

All of these reasons are why a good vegetative LED grow light is considered to be an essential part of any marijuana garden, especially if you get a hold of a full-spectrum LED vegetative grow light. This type of light can help you grow your marijuana plants through both the vegetative stage and the flowering stage. While our article is centered on finding the best LED grow lights for vegetative growth, we will mainly be focusing on the best lights for weed that use the full-spectrum of light. That way, you won’t have to buy another grow light for the bloom phase later on. 

UNDERSTANDING THE VEGETATIVE PHASE OF GROWTH AND WHY YOU NEED VEG LIGHTS FOR WEED

The vegetative stage of the growth is the fourth stage in the marijuana plant’s seven-stage growth cycle. It comes after the seed, germination, and seedling stages and is followed by the pre-flowering, flowering and harvest stages. The vegetative stage is the stage of growth where the seedling begins to mature into a proper plant. During this time, a large number of branches and leaves will start to appear. Here, the plant gets sturdier as the stem gets thicker and the height of the plant increases tenfold. This is the phase of growth where you will need to provide a lot of light to the plant, especially with one of the best lights for weed, to ensure that it is getting enough light for photosynthesis. This is quite important because the green portions of the plants will still be growing at this stage. A plant is only considered fully matured at the next stage. When you reach this stage, you will need high humidity levels so the leaves can directly absorb the moisture from their environment instead of from the roots.

7 Best LED Veg Lights for Vegetative Growth

Now that you know what LED lights for vegetative growth are and what the vegetative stage of growth is, here’s a look at the 7 best LED lights for vegetative growth.

How to Choose the Best Veg Light for Growing Marijuana

Now that you know what to look for in the best LED veg light, you should also know some crucial factors that need to be considered before you buy a grow light

  • Spectrum: When looking for the best LED light for vegetative growth, you’ll want to find a grow light that offers a full-spectrum of light. This means you are getting the reds as well as the blues. The red end of the spectrum is important for the growth of marijuana in the flowering stage, while the blue end is good for the growth and vegetative stages of the marijuana plant’s life cycle.
  • Coverage: You should know how wide the coverage of the grow light is. Will it be enough to cover your grow tent? Make sure that the grow light(s) you are getting are enough to cover the entire grow tent but do not exceed it.
  • Power Consumption: You need to see how much power your grow light consumes before you buy it. It’s best not to go by the wattage reading that the light provides you, though. A 2000W grow light might consume only about 800 to 1300W of power. This is something you need to double check to make sure you’re getting a device that doesn’t consume too much power.
  • Cooling: Cooling is pretty important for a grow light because light emits heat. While the best veg lights heat up less than other grow lights, they still emit quite a bit of heat that can damage either the plants or the equipment itself. Hence, you need to make sure the light has proper cooling arrangements to dissipate the heat that the light generates.
  • Cost/Warranty: Last but not the least is the cost and the warranty. Grow lights are one of the most expensive parts of an indoor growth setup, and they can cost you anywhere between $50 to $1000 depending on what kind of a grow light you’re getting. Make sure to invest in only the best LED for veg. Most grow lights also offer at least a 2 years of warranty.

Frequently Asked Questions (FAQs) About the Best Light for Vegetative Growth

Here are some frequently asked questions about the best LED lights for weed:

1. HOW MUCH LIGHT DO PLANTS NEED IN THE VEGETATIVE STAGE?

The vegetative stage is a stage in the plant’s growth where it needs a LOT of light. You may be wondering: exactly how much should the photoperiod be? You can start off by giving your plant as much as 20 to 22 hours of light for a few days before eventually easing it down to about 18 hours of light and 6 hours of darkness a day as the plant begins to grow. Eventually, as you enter the pre-flowering phase, you can reduce it to 16 hours of light and then down to 12 hours of light when you want to trigger your plants into the flowering stage.  

2. CAN I GROW A PLANT WITHOUT USING AN LED VEGETATIVE GROW LIGHT?

Yes, you can make use of other types of grow lights to grow your marijuana plants. These include HPS lights, Metal Halides, CFL lights and other similar options of lighting. However, LED grow lights are generally considered the best out of all these because they are non-toxic, cheaper to operate, and last longer. While you could eliminate the need for a grow light and choose to grow your marijuana outdoors or in an area where you get a lot of sunlight, using grow lights gives you a greater advantage. You can control the intensity of the light as well as the amount of hours that the light is provided to the plant. 

3. HOW DOES LIGHT DETERMINE THE SHIFT FROM VEGETATIVE STAGE TO FLOWERING STAGE?

The “photoperiod” is a term used to describe the amount of time that light should be provided to plants. The photoperiod determines many things, such as the growth of the plant and phase of growth. When you reduce the photoperiod from 18-16 hours a day to 12 hours a day as the pre-flowering phase comes to an end, flowering will begin. 

4. HOW MANY HOURS OF DARKNESS (NON-LIGHT HOURS) DO PLANTS NEED?

The amount of non-light hours or hours of darkness that you provide to your marijuana plants depends a lot on the phase of growth your plants are in. During the early stages, you can provide up to 2-3 hours of darkness. During the peak vegetative phase, you can provide about 6 hours of darkness. The pre-flowering stage requires about 8 to 10 hours of darkness. Finally, the flowering phase needs 12 to 14 hours of darkness. 

5. IS IT LEGAL TO USE AN LED VEGETATIVE GROW LIGHT?

Yes, it is completely legal to use a vegetative LED grow light. Growers use these grow lights to grow not only marijuana but also many other plants. However, if you are planning to grow marijuana using a vegetative grow light, you need to check with your local law enforcement if it is legal to do so. Grow lights are legal, but growing weed might be illegal, so it’s best to watch out for that.
