More and more people are interested in indoor gardening.

Due to the increasing number of people coming to the big cities to find work, green and vegetative spaces have slowly become smaller in number.

This greatly affects the production of crops and food as open room cultivation can no longer be relied on. This is when indoor gardening fits in.

Indoor gardening makes use of a grow tent and LED light, which serve as the optimal growing environment conducive for the blooming and fruiting stage of plants and fruits. 

Today’s article will specifically discuss the best LED light for 4×4 grow tent.

A lot of growers use 1000 watts to 1500 watts of LED light to heat a 4×4 grow tent. Some would resort to 4 pieces of 300 watts while others would go for two 600watts lights.

LED Grow Lights Vs Fluorescent Lights: Which Is Best For Indoor Gardening?

The use of LED lights to yield fruits and vegetables indoors is not something that is unheard of. In fact, indoor gardening has been a trend for a few years now.

But those who have just started this gardening technique are quite confused as to which is the best LED light for a 4×4 grow tent.

Below is a short yet comprehensive comparison between the two types of light:

Fluorescent Light

This type of light is also known as CFL bulbs. It has been deemed as an effective growing light for indoor plants for years. This also comes in various types but one that is most popular is the T5 tubes fluorescent light.

Why do people love it?

There are two reasons actually, namely wide availability and affordability. Most home hardware and light shops sell the T5 tubes at a very reasonable price. Therefore, first-time growers would most likely buy this one just to test the water first.

What to bear in mind?

One has to know that fluorescent bulbs are much less efficient and actually diffuse light. So, your indoor plants will still bloom and produce fruit but not that abundant.

LED Light

LED grow lights are quite new as compared to the CFL kinds, but this doesn’t mean that not many people are using this light. This light appears around 10 to 15 years ago and has been the preferred grow light of serious growers.

Why do people love it?

Personally, we would recommend LED lights for those who are seeking to build a large indoor garden. Why? Because this is much more efficient and encourages fast growth among plants. Most of the heat from the bulb will be directed to the plants, thus they grow much quickly and healthily.

But don’t get confused its high heat performance with overheating as LED emits heat at a controlled level, enough to be absorbed by plants and fruits.

What to bear in mind?

This kind is more expensive than fluorescent light. The cheapest would still be twice or thrice the price of CFL bulbs and the most advanced version could go as high as 10 times more.

The Verdict?

Clearly, the best grow light is the LED light as this is much more efficient and the heat coming from the bulb is concentrated directly to the plant. This means that no light is wasted and plants get all the heat they need for the blooming and fruiting phase.

How To Choose The Best LED Grow Light For A 4×4 Grow Tent

Now that we have established why an LED light is a better choice, we will share with you some tips on how to choose the best LED grow light for your tent.

Check out the tips below:

Efficiency Rating

The efficiency rating refers to how much heat can the light generate and how much of these heat is actually directed to the plants.

The higher the efficiency rating is the more heat the light can generate. This also means that less electricity is being wasted.

Burning Time

LED lights generally have longer burning time as compared to other grow lights. However, some LED grow light brands have successfully created bulbs that can last up to 100,000 hours.

Most standard and smaller LEDs can last 10,000 to 20,000 hours, and these can still give value to your money.

Shape And Size

The shape also matters since this could affect how the light is directed inside the grow tent. You can purchase rectangular, round, or square LED lights. This is usually composed of smaller bulbs with smaller watts that when used together can generate high heat which is enough to stimulate growth in plants.

In addition, you must match the size of your LED light to the area of your 4×4 grow tent. This is to ensure that the heat is balanced and that the plants receive heat evenly.

What’s more is that too hot grow tent will drain off the leaves of the plants from the green coloring, which is basically an important factor in the plant’s food production.


You do not need to be a professional in order to set up LED lights in your grow tent. The best LED light for 4×4 grow tent can be installed easily and without additional cost.


Of course, setting a budget range will help you avoid spending too much. This will also help you narrow down your choices to the available lights within your budget. You can get LED lights under $200.

Meanwhile, a price range of $800 to $1,000 is the most expensive LED grow lights you can purchase. These types are usually used in large commercial indoor gardens.
