In this article, we talk about the best LED grow lights for your small cannabis grow.


Are you new to growing cannabis plants indoors? Or maybe you’re an experienced grower, but want to replace your traditional lights with LEDs? Either way, we got you covered.

LED (Light Emitting Diodes) lights are a more durable, eco-friendly way to mimic the sun for your indoor plants. These lights don’t use gas, contain zero lead & mercury, have a long life, and produce low amounts of heat. What’s not to love, right?

For these reasons, many people are swapping out their current grow lights with LEDs. As manufacturers become more innovative, LEDs are becoming less expensive and more energy efficient. If you feel drawn to exploring the LED options out there, then check out this article. We’ll go into detail about the best LED grow lights for a 2’ x 2’ tent.


Note: Looking a grow tent too? Here are a few to consider:
Plant House Indoor Grow Tent 2’x2’x67″
Gorilla Grow Tent Shorty 2’x2.5′
Gorilla Grow Tent LITE LINE 2’x2.5×5’7″
Gorilla Grow Tent 2’x2.5′


Can any LED light be used as a grow light?

Not quite. LED grow lights take into account the power supply needed for plants and have a full spectrum of lights. Also, they have built-in fans to cool down the lights, and some are dimmable, while others are easily adjustable. All these design specs make LED grow lights more suitable for a grow space than ordinary LED lights.

Top 7 LEDs for 2 x 2 grow tents

Quick look at top LED grow light models for 2’ x 2’ tent:

  1. Best overall: California Light Works SolarSystem 275 (200w)
  2. Best bang for your buck: HLG 225 Elite (225w)
  3. Best light for one plant: HLG 65 V2 (65w)

1. California Light Works SolarSystem 275 LED Grow Light


This lightweight LED grow light weighs a little over seven pounds and is 40% more energy efficient compared to its non-LED competition. Its ability to mimic natural sunlight makes it perfect for all stages of a plant’s life, including seedling, vegetation, and bloom.

The reason this guy takes the number one spot is not due to it’s price, because it’s the most expensive of all the lights, but it’s also engineered by a company based in Southern California with a long history of LED lighting technology. This isn’t your typical overseas import that will fail after 2 years. The California Light Works SolarSystem uses some of the most state of the art LEDs available with a great heat dissipation design giving it the best output (umol/Joule 400-700nm for the scientist out there) of 2.4. The next closest model is the HLG 225 at 2.2.

If you decide to add on the SolarSystem Controller, you have the ability to adjust the heat settings based on the growth phase. However, the controller isn’t mandatory, so if you don’t use it, be sure to switch the flip on the light to “manual mode.”

Another key feature of the SolarSystem 275 is that you’ll never have to change the bulb. It powers on for 50,000 hours or more. And if anything happens to the bulb, California Light Works has you covered under its 5-year warranty. Additionally, installing this light is simple and maintenance is a breeze.

2. Horticulture Lighting Group HLG Elite 225W LED Grow Light

The 225W Elite LED grow light by Horticulture Lighting Group (HLG) can replace a 315W light and still give the same output but with less overall heat. This light is custom designed, highly efficient, small and compact, yet can cover a lot of space, making it a perfect LED for a 2’ x 2’ grow tent.

It operates on a fixed spectrum at 4000k but has added 630 and 600 red and deep red LEDs to achieve the full spectrum. The HLG Elite is the type of light you can use during propagation, vegetation, and all the way through harvest.

The reason the HLG 225 takes our number two spot is the combination of great light output, high quality LED diodes and a great price at under $300 to your door. It looks like it has a funky haircut, but that’s its heat sink making the diodes run more efficiently.

    LED FAQs

    1. How many plants can I grow with a 200W LED light?

    When using a 200W cannabis LED light, you can grow between 1 to 3 plants. The actual number will depend on the size of your grow tent or space and the strains you want to grow. Indica strains grow wide and bushy, while Sativa strains grow lean and tall.

    However, autos (auto-flowering strains) stay very small and only reach a few feet in height. So, the number of plants you can grow with a 200W LED light depends on these factors.

    2. How high should I hang my LED grow light?

    If you buy a non-dimmable light you’ll need to adjust the height of your LED lights throughout the various phases of the plant’s growth cycle. Hanging a light too close to the plants can damage them and affect their health. So, always look at the manufacturer’s recommendation to learn how high to place the light above your plant. To get a general idea, here are the estimated heights at different stages of growth.

    3. How much does it cost to run a LED grow light?

    LED lights are much more efficient than traditional lights (i.e. HPS, T5, CFL, and incandescents), which means you save a lot of money on energy costs. The cost varies depending on the wattage of your grow light and the electricity costs of the state you live in.

    Let’s look at an example together using the following assumptions:

    • Power of your LED grow light: 200W = 0.20 kW/hour
    • State of residence: Arizona
    • Electricity rate in AZ: 12.78 cents per kilowatt-hour (or $0.1278/kWh)
    • Vegetative state = 18 hours of light/day for 70 days (10 weeks)
    • Flowering state = 12 hours of light/day for 56 days (8 weeks)

    Calculations:

    Cost to run light during veg = 0.20kW/hour x $0.1278 x 18 hours = $0.46/day
    Cost to run light during bloom = 0.20kW/hour x $0.1278 x 12 hours = $0.31/day

    $0.46 x 70 days = $32.20
    $0.31 x 56 days = $17.36

    The total electricity cost to run your lights during veg and bloom phases = $49.56

    As you can see, over a 126 day (18 week period), the electricity cost for the light in your grow tent is minimal. Go ahead and add in the extra cost of running your lights during propagation and seedling to arrive at your total light cost from seed to harvest.

    4. What size LED light for 2 x 2 grow tent?

    You have many options to choose from that range in size, power, voltage, and capabilities. Some lights are better suited for propagation, seedling, and vegetation, some are great for the bloom phase, while others are made for all phases of the plant’s life.

    So decide if you want one main light or a few supporting lights. Then read through the list of the best LED grow lights that we discussed in this article. At that point, you’ll be able to tell which one(s) fits your needs the most.
