Buying Guide for 3×3 Tent Grow Light

Whenever you need help deciding on the best led grow light for 3×3 grow tent, you need to consider specific points. We plan to give you reliable information and expertise on how to choose LED light to grow. Many other variables need to be recognized.


To know the size of led light, what size of led light do you need, and for what purpose. First, you have to determine where you will set it, such as your grow space, to guide the tent size. Per square foot of grow room, you have to use a minimum of 50 watts of the led light. 

If you want a flood of light on your plants or doing professional farming, then, of course, you need a big grow space and more sunshine. Let me explain the calculation, length, and multiply the width of the grow space. Then multiply the number by 50W, giving the required wattage you need for your growing area.


The quality of led light is essential because plants have different relationships with light. All plants gain nutrition and growth from natural sunlight. Your crops need to spread the light across evenly distributed the dark and hot spots under-exposed or overexposed which PAR is available to plants. It also can negatively impact the overall quality of the harvest.

Light intensity:

For growing space, you need the right amount of light intensity for the plant’s growth stage. Sometimes on your plants, there is too much light or too low light intensity. Both are dangerous to your plant’s growth. For a 3×3 foot grow tent, you have to consider a 250-watt HPS grow light.

Tent Type:

The tent type matters a lot while setting the led lights for grow space. The tent type depends on your farming type, which you are going to carry out. There are two kinds of tents. one is a multi-chamber tent, and the other is a single chamber tent. If you want it for professional work, such as using it for different kinds of crops, go for a multi-chamber tent. Or, if you want one type of crop, then a single chamber tent is perfect.


The led light price is high; that’s why the growth through led light is expensive. The light cost is coming down, and the quality of light is going up. The light pricing range is $500 to $2000. The traditional HID setup is less expensive than the led light setup. For those who want to produce high quality with large amounts of yield doesn’t matter.


Most of the LED lights work without having any problem. But sometimes people complain that the fans got broken, LEDs go out, or the driver fails. Before investing money, check their warranty to not worry about LED lights’ upcoming problems. The manufacturer will take care of all of the issues. The range of LEDs warranty between 1 to 10 years, but most companies offer 3 and 5 years of warranty. Before buying, read all the warranty instructions of the manufacturer on their website.
