Top 5 Best LED Grow Light For 4X4 Grow Tents (2024)

Last Updated on December, 2023 by Rob Wilson

Marijuana can be grown in several different ways based on the interest and the comfort of the grower. You can grow it outdoors, as it has always been grown for thousands of years – or you can choose to grow it indoors, which is the latest direction towards which the trend has been shifting. Nonetheless, the end product is pretty much the same in both the cases. Growers, however, have been shifting towards growing their weed indoor at quite an increasing pace because when you grow your weed indoors, you get to control several factors which you just can’t while growing it outdoors – the most important of them all being lighting. In this article, we take a detailed look at the best LED Grow lights for 4×4 grow tents in 2022.

4×4 grow tents are among the most popular and preferred size of grow tents for small-scale growers as they are neither too large nor too small and can easily fit in the room. They also have a lot of space inside it which makes sure that plants get adequate ‘social distancing’ as well as there’s sufficient space to hang equipment, etc. These grow tents require an artificial source of lighting which can replace the sun. This is where these LED grow lights fit into the picture.

As we proceed with this article, we shall be taking a closer and detailed look at what LED grow lights are, why they are needed – and why are they considered the best kind of lighting available for growing marijuana indoors at the moment. We shall also be providing a detailed and in-depth review of the 5 best LED grow lights for 4×4 grow tents in 2022. These are reviews which cover all the aspects of the grow light that you need to know and provide you with detailed pros and cons about these lights. The thing with LED lights is that there are just too many brands in the markets and you might get confused as to which are the best ones that you should be buying. Hence, in this article, we shall help you clear up that confusion by reviewing all the top names in the markets. 

What are Grow Lights? Why Do Plants Need Them?

When you grow a marijuana plant outdoors, you do not need to provide it any special treatment (especially when it grows in nature unmonitored). However, based on years of research we know that plants need a specific kind of light, a specific kind of soil and a specific kind of temperature, humidity, nutrition, etc. to grow properly. While marijuana plants grow outdoors, they grow in uncontrolled situations. An excess of rain or snow might damage the plants. The lack of light might also be counterproductive. Hence, grow lights are used when growing weed indoors so that you can provide your plants with the best and ideal lighting conditions. 

For those wondering what these ideal conditions are, when you are using a full-spectrum LED grow light to grow weed in a grow tent, you are providing the plant with lighting similar to the natural light of the sun in terms of the wavelengths of different lights. Moreover, with grow lights, you also make sure that you can provide lighting for extended (or reduced) hours based on the needs of the plants. You can increase and decrease the warmth, intensity and even the total lighting hours which is not possible when the plant is growing out in nature.  

Types of Grow Lights

There are a number of different kinds of grow lights such as fluorescent lights, high-intensity discharge lights (which include metal halides and high-pressure sodium lamps), etc. Not all of these grow lights offer you a complete spectrum and in both these cases, you need to change bulbs from time to time to switch between the warm and the cool spectrum of lighting. Metal Halides offer the cool blue shade while the HPS lamps offer a warm/red shade. On the other hand with fluorescent lighting, you will need to change between the cool daylight bulbs and warm white bulbs which offer different spectrums of lighting. 

Why Should You Use LED Grow Lights?

That knowledge of spectrum now brings us to LED grow lights. LED lights are the latest and the most popular form of lighting these days as you can use one panel of light which provides both kinds of lights. Moreover, it consumes far lesser electricity in comparison to the older forms of lighting. LED lights also tend to last for much longer and are easier to dispose of as they do not carry any chemicals in them! These grow lights are also easy to operate and beginner-friendly as there’s no such things like ballasts or changing of bulbs involved in LED lighting.

Buyer’s Guide to LED Grow Lights: How to Choose the Best Lights for Your 4×4 Grow Tent?

There are a number of different factors that you need to keep in mind when you are looking forward to buying an LED grow light for your marijuana plant. First off, you need to know if the light you are buying will be providing you with sufficient coverage as to cover the 4×4 grow tent properly. In addition to that, you need to know exactly how much area does it cover during the vegetative phase and how much does it cover during the flowering phase when the light is lowered. Always make sure the flowering area is sufficient to cover your tent before you finalize on the light. 

Post the coverage, you need to check for power consumption which is another important factor for growers. The wattage written on the product’s name is usually the output that you get and not the power draw (which is generally lesser). Hence, always check the product details for the exact power draw, which will tell you about the amount of power that is being drawn from the wall socket. In addition to that, do check the durability of the product – as well as the total lifespan. Most good LED grow lights will last anywhere 75,000 to 100,000 hours! 

Lastly, also check if the company that is making it has service centers in your country. Most major players are based in China (or other nearby Asian regions) and have warehouses and service centers in US, UK, Australia, EU, etc. Do check the warranty period that they are offering (a minimum of three years is recommended) as well. Lastly, the price and your budget should also be kept in mind before you make a final purchase.


Frequently Asked Questions (FAQs) About LED Grow Lights

There are many questions that we get asked repeatedly. We’ve compiled some of them here so that in case you too might be having a similar doubt, it will help you clear it up!

1. How much do these grow lights cost?

Every grow light costs a different amount and while some are as cheap as $60 to $75, there are other more expensive ones which come with better quality parts and longer warranties which might cost you three to four times more than these cheap lights. On an average, however, $150-$250 should be the range you should eye for. 

2. Instead of using one big light can I use multiple small grow lights for my 4×4 grow tent?

Yes, that can be done too. Many growers do that instead of using one grow light but most growers prefer using one grow light since it offers a more uniform lighting experience. 

3. Is there any harm in buying a grow light which covers greater than a 4×4 area for my 4×4 grow tent?

Absolutely no problem in doing that! That can be useful for you if you ever decide to upgrade your lighting setup or your tent size. 

4. Is it legal to use these lights to grow weed? 

That honestly depends upon your local laws and regulations. Growing weed for recreational or medicinal purposes might be legal in some areas while others might have some restrictions. Even the areas which permit you to grow your own weed are likely to have a fixed number of plants that you are allowed to grow so make sure you’re well versed with these legal issues before you start your own growing operations!
