Best LED Grow Lights For (3' X 3') Cannabis Grow Tent

Introduction

LEDs are the most reliable lights that provide the perfect amount of light to the plants required for active growth phases. The plants go through different stages, and they need natural and synthetic things such as air, light, and water. Here the only thing is sunlight which is not available in the indoor plantation. So, you can use LEDs to boost the photosynthesis process of plants. There are multiple types and sizes are available for the different sizes of grow tents for sufficient growth. Moreover, the plants also required blue, red, and multicolor light at the specific stage of development. So that we are recommending you the best LED grow light for 3×3 grow tent for better results.

What are the Benefits of LED Grow Lights?

Why use grow lights at all? Here are the benefits:

Low energy cost
LED light bulbs only use about 10% of the energy that regular light bulbs use, so they are very cost effective to run.

This means they are ideal for larger grow tent setups as well as cheap indoor grow setups for anyone concerned about costs.

Optimal growth
You can run LED grow lights all day and all night without running the risk of burning the plants or significantly increasing your energy bill.

Because of this, the harvest cycle is not only faster than it would be in an outdoor setting, but it also helps produce a higher, better quality yield due to the consistency of lighting.

Optimized light spectrum 

The energy that LED bulb output can be adjusted to specific frequency bands, which means that you won’t be wasting energy in producing light in the wrong area of the spectrum.

This allows you to fine tune the light you are supplying to your plants to best match their growth needs.

Long lifespan
LEDs typically last 50,000–100,000 hours, easily 50 times longer than an ordinary incandescent lightbulb. This translates to about 10 years of effective lighting, after which they tend to dim rather than going out.

They are also fully recyclable, which makes them the most environmentally-friendly light bulbs too.

Low heat
LEDs emit very little heat and are relatively cool to the touch even when running 24/7, so it is easier to control the temperature in your grow tent and there is no risk of the bulbs burning the plants.

Fluorescent lamps and incandescent lamps will interfere with the plant growth. In comparison, incandescent lamps typically produce about 80% more heat than LEDs, potentially harming the plants.

This also means that you save on HVAC costs and can water your plants less frequently.

More control
The best grow lights allow you to control the amount of light the bulb emits, the lighting schedule and even the color spectrum of the light.

This allows you to tailor your lighting to a specific plant type and harvest schedule with ease.

Compact
LEDs are compact grow lights, so you can easily set them up even in a smaller grow tent or room without creating clutter.

There are also LED lights that can be chained together, which will help in eliminating extra wiring.

After you’ve decided the right grow tent, you need to fill it up with the right equipment. And the grow light is the most important of them all.

How Many Watts Do I Need For A 3×3? The typical LED is going to draw approximately 32 watts to cover one-square-foot for flowering. For a 3×3 you’re it’s somewhere between 250 and 300 watts.

However the latest LED lights provide more light intensity (and spectrum quality) with less watts. And provide highest yield/square foot than any other kind of grow light. Here are the best three grow lights for a 3×3 grow tent:

Do LED Grow Lights Use a Lot of Electricity? 

LED grow lights are very energy efficient and they do not use a lot of electricity. Traditional HID grow lights consume a ton of electricity, in fact paying for the electricity used to be one of the major costs of homegrown weed. Each HID bulb can consume anywhere from 100 Watts to 1,000 Watts, so it depends on the size of your grow, but switching to LED grow lights can save you 50% to 70% in actual power consumption.

Many LED grow lights are still described in the wattage of their HID equivalent in terms of brightness. As you can see in the list above, though, many brands do not use the exact same wattage equivalent in their naming conventions — Make sure to check the manufacturer’s specifications on your grow light before purchasing.

It is a good idea to go by the recommended coverage area for a particular LED grow light as opposed to the HID equivalent, as this measurement is far less subjective.

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.

Size:
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.

Quality:
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.

Price:
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.

Warranty:
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.

How Far Should LED Lights Be From Plants? 

LED grow lights do not pose the same risk of burning plants as HID bulbs, but their light is extremely intense and can bleach the tips of your plants. It is best to mount them on easily adjustable lines so that you can raise them as your plants grow taller.

You may be surprised to learn that LED grow lights must be hung even farther away from the canopy than HID lights. Because LED grow lights offer such a powerful light spectrum, it can be too intense and overwhelming to the plants and it can cause them to look bleached. This will, of course, affect your yield and quality of your buds.

Small lights under 200W should be hung at least 15” above your plants, and around 20” for seedlings.
Medium-sized lights under 800W should be hung between 20” to 26” above, and large lights over 800W should be hung between 26” and 45” above your plants. 

The best way to know exactly how high to mount your LED lights is to check the manufacturer’s recommendation. They should list a height for both vegetative and flowering growth, because flowering plants require a bit more intensity.

Conclusion

The bottom line is that these are some best options for 3×3 tents currently in our opinion. We have tried to choose ones that are durable, have a long lifespan, are bright with lots of lumens and a good coverage area, and are full spectrum for complete growth for all stages. A decent LED grow light is perfect for a small grow tent such as the size we are talking about today.
