When a marijuana plant grows wild in the nature, it survives because everything that it needs for basic growth is right there. The sunlight, air, rain/groundwater is all that it needs along with the natural cycle of the sun and the changing environment. However, when it comes to professionally growing the marijuana plant indoors, growers need to take care of a lot of things and setting the right kind of lighting is perhaps the most important of all that. The right kind of lighting can be set using the best LED grow lights. Over the course of this article, we shall focus on the top 7 best LED grow lights for vegetative growth which will help your plant get greener and leafier and make sure it is getting optimum levels of growth.
Here, we shall first take a closer look at what an LED grow light is and why is it so useful for the growth of the plants. Followed by this, we shall be taking a closer look at what the vegetative phase of growth is. Then, we shall look at the 4 best LED grow lights for vegetative growth in detail, along with the pros and cons of each of them. Post that, we take a quick look at a buyer’s guide where you will know what to look for in a grow light before you buy it. Lastly, before we conclude, we look at some frequently asked questions about LED grow lights. Let us now begin by addressing some basic questions first:
What is an LED grow light and why is it useful?
There are a number of different kinds of grow lights but all of them serve the same purpose. They ensure that the plant that you are growing indoors gets enough lighting in the absence of sunlight. These grow lights have lights of different wavelengths which make sure they recreate the natural sunlight inside a controlled environment. Unlike the natural cycle of the sun, however, you can control exactly how much light you are giving to the plants and for how long. This helps the growers create what they call an ‘optimal’ plant which offers high volumes of yield in the end.
There are a number of different types of grow lights but LED grow lights are usually considered to be the best option for growers. Other types of grow lights include High-Pressure Sodium grow lights, metal halides, CFL grow lights, etc. However, LED grow lights are better because of many reasons – first off, they are long-lasting and 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 off. Then there’s the biggest benefit of it all – LED grow lights have a much cheaper operating cost when you compare it with other traditional grow lights.
It is because of all these reasons put together that LED grow lights are considered to be the best and the most useful of them all, especially when you get hold of a full-spectrum LED grow light which helps you grow your plants through both, the vegetative as well as the flowering stage. While our article is on the best LED grow lights for vegetative growth, we shall only be considering the full-spectrum grow lights so that you don’t need to buy another grow light for the bloom phase later on. .
Understanding the Vegetative Phase of Growth
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 stage and is followed by the pre-flowering, flowering and harvest stages. This is the stage of the growth where the seedling becomes to mature into actually becoming a proper plant and a large number of branches and leaves start to appear. Here, the plant gets sturdier as the stem gets thicker and the height of the plant gets a major boost from being a tiny seedling to quite a tall plant. This is the phase of growth where you would need to provide a lot of light to the plant to ensure that they are getting enough light for photosynthesis. This is quite important given that the green portions of the plants are still growing. A plant is fully matured by the next stage. In this stage, you need high humidity as well as the leaves can directly absorb the moisture from the environment instead of using the roots.

How to Choose the Best LED grow lights for growing marijuana?
With the knowledge of the four best LED grow lights for growing marijuana now with you, you must also know some crucial factors that you must consider before you buy these grow lights. You need to consider the following things:
- Spectrum: You must get a grow light which offers a full-spectrum lighting. This means you are getting the reds as well as the blues. The red end of the spectrum is important for the growth of the plants in the flowering stages while the blue end is good for the growth and vegetative stages of the plant’s life cycle.
- Coverage: You must 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 or are not less than the size of the tent otherwise it might not be optimal!
- Power Consumption: You need to see how much power the grow light consumes off the power socket. Don’t go by the wattage reading that the light provides you. A 2000W grow light might consume only about 800 to 1300W of power. This is something you need to check to make sure you’re getting a device which is easy on the power consumption front.
- Cooling: Cooling is pretty important for a grow light because lights emit a certain amount of heat. While LED grow lights heat up lesser compared to other grow lights, there’s still quite a bit of heat which might end up damaging either the plants or the equipment itself. Hence you need to make sure there’s enough cooling arrangements to dissipate the heat that the light generates.
- Cost, Warranty: Last but not the least, cost matters too. Grow lights are one of the most expensive parts of the indoor growth setup and they cost you anywhere between $50 to $1000 depending on what kind of a grow light you’re getting. Invest smartly. Furthermore, most grow lights offer at least 2 years of warranty so make sure that’s the minimum you’re getting.

Frequently Asked Questions (FAQs) about Grow Lights for Vegetative Growth
Here are some frequently asked questions about grow lights for vegetative growth which we have tried to answer to the best of our capabilities:
1. How much light do plants need in the vegetative stage?
The vegetative stage is a stage in the growth of the plant where it needs a LOT of light. Exactly how much should the photoperiod be? You can start off by giving as much as 20 to 22 hours of light for a few days then eventually ease it down to about 18 hours of light and 6 hours of darkness when the plant begins to grow. Eventually, as you enter the pre-flowering phase, you can reduce it to 16 hours and down to 12 hours when you want to trigger your plants into the flowering stage.
2. Can I grow a plant without using an LED 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 due to multiple reasons such as being non-toxic, being cheaper to operate and for being long-lasting. In fact, you can totally eliminate the need for using grow lights and even choose to grow your plant outdoors or in an area where you get a lot of sunlight. However, using grow lights gives you a greater advantage as 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 the term which is used to describe the amount of time that the light should be provided to plants. Photoperiod determines many things such as the growth of the plant, as well as helps change the phase of growth too. When you reduce the photoperiod from 18-16 hours to 12 hours after the pre-flowering phase is nearing its completion, this is when flowering begins.
4. How many hours of darkness (non-light hours) do plants need?
The amount of non-light hours or hours of darkness that you are providing to your marijuana plants depends a lot upon the phase of growth these plants are in. During the early stages, you can provide up to 2-3 hours of darkness, during peak vegetative phase, you can provide about 6 hours of darkness, pre-flowering would require 8 to 10 hours of darkness while flowering phase needs 12 to 14 hours of darkness.
5. Is it legal to use LED grow lights?
Yes, it is completely legal to use LED grow lights. Growers use these grow lights to grow not only marijuana, but also many other plants. However, if you are planning to grow marijuana using LED grow lights, 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 watch out for that.
