As you might know by now, there’s a huge difference between normal LED lights and these LED lights that are used in grow tents. Both of them have different purposes, and the main purpose for these LED lights used in a grow tent is to help the plants to grow. Well, if you’re purchasing a 4×4 grow light, there are certain factors that you need to consider, and these factors are listed below:

1. Heat Generated by light

Well, the first thing that you need to determine is the type of plants that you’ll be growing because there are plants that will require both light and heat to grow at a good pace. For such plants, you need to buy a LED light which can generate a good amount of heat as well along with good quality light. 

2. Burning Time 

In terms of LED lights, durability is the burning time of it. No one would like to change the lights of the grow tent frequently, as it can disturb the growth of the plant as well. So, it’s better to get an LED light that has a good burning time. You can check this thing on the label of the light, as the expected lifespan of all the lights is printed on their labels. 

3. Size And Shape Of The Light

As you are using a 4×4 grow tent, which isn’t too big or small, but you still have a limited area to fit the light. So, while purchasing the light, you need to take care of the size of the light as well, because if the size is too big for the tent, then it’ll be a waste.

Also, the shape of the light does matter a lot because if the plants do not receive enough light, then they’ll not grow properly. So, always go for the one which has a shape that can distribute the light evenly on all the areas of the tent so that no plant would get more light and no plant will receive little light. 

4. Easy to install

Well, to save your time, you need a light which can be installed easily. However, it’s just a matter of time to install LED grow lights, but still, there are many models present in the market, which may make the installation process more challenging. So, try to avoid such models and go for the ones which are easy to install. 

5. Spectrum

It’s always recommended to buy the LED grow light which has different wavelengths. This is so because a different light spectrum, including red, white, blue, makes the plants grow much better.

6. Intensity of Light

Another important factor to consider is the intensity of the light that the LED grow light offers. Purchasing the one which gives a very high or very low intensity can ruin your plants. So getting an ideal light intensity is very important. Well, for determining the intensity you need, the growth stage and size of the space matter. For each square foot, 300 to 800 lumens of light intensity are considered to be the most ideal. 

7. Photosynthetically Active Radiation (PAR) 

PAR refers to the range of wavelengths of light that is used by plants for photosynthesis.

You need to provide different light in the different stages of plant life, like when the plant is in the vegetative phase, it’s important to provide blue wavelength to the plant, and if it is in the flowering stage, the orange or red wavelength of light is required.

So, you must either look for the one which can give you both the types of wavelengths, or else you can change the light depending on the phase of the plants. 

Well, it’s evident that the plants that are directly under the light receive the most PAR value, but it gets lesser towards the sides. However, providing a high PAR value is not always better, but providing good quality LED light is necessary.

8. Consumes Less Energy

Another important thing to consider is the amount of energy that the LED grow light will consume. It’s quite obvious that you will be using the light for a long time in a day, which can be around 8 hours. This means that it can easily make your electricity bill rise like anything.

So, if you’ll purchase the one which consumes less energy, it will definitely help you in saving more money. However, if you will buy an energy-saving LED, there are chances that it will not be of good quality. So, you need to look for the light, which has both the things in it, because lack of one thing can make you pay the price. 

9. Cost

The last factor that you need to keep in mind is money. You can find poor quality LED grow lights in an expensive range, and you can also find good quality LED grow lights in an affordable range. So, here you need to pay more attention to the quality and to the price simultaneously.

It’s always better to decide your price range first and then look for the good options that fall within the range. By doing so, you’ll end up having the one which will give you everything you need.

When it comes to growing plants, we have to be very careful and provide all the things that a plant needs to grow properly.

However, the caring of the plants increases when you decide to grow them indoors, like in a grow tent. The first thing that you need to make sure of is the distance between the plants and the light that you will hand upon them.

If you will keep it too close, the plants will burn or may not grow properly. Well, initially, it’s said to place the lights 30 to 32 inches above the plants. When your whole setup is done, you can observe your plants and make sure that they are not burning and have enough area to grow.

Well, to wrap this article up, we would say that having a good quality LED grow light for your 4×4 grow tent is an essential thing. With time new technologies will definitely come, and you can easily get what you exactly want. This is only possible when you know all the things and keep those things in mind while purchasing. 

Well, when it comes to purchasing the best LED light for 4×4 grow tent, all the things that are mentioned above are quite important for your indoor plants to grow at a good rate and make you satisfied at the end. So, choose the light wisely to make your plants healthy.
