The Best Grow Lights For A 2×4 Grow Tent – Pictures, Specs, And More

What are the finest grow light options for a 2×4 grow tent and how do you choose them? Take a look at one of the following alternatives: A 150-watt high-pressure sodium (HPS) grow light, a Spider Farmer SF-2000, a Green Sunshine ES300, or the HLG 320-watt DIY quantum board LED grow light are all good options. When selecting a grow light for a 2×4 foot grow tent, the light intensity and consistent coverage area of the lamps are the most significant elements to consider, according to the manufacturer.

All of the alternatives I’ve listed below fulfill or surpass those standards.

Despite the fact that there are a plethora of perplexing lighting options available, either of these grow lights will function well in your 2×4 grow tent.

Many folks who are contemplating 2×4 foot grow tents are also considering 3×3 foot grow tents, according to my observations.

Budget Choice:Hydroplanet 150 watt HPS grow light

Why am I proposing an HPS grow lamp as one among your two-by-four-foot grow tent’s lighting options? I communicate to farmers on a regular basis, and some of them are on a tight budget. For a variety of reasons, this 150 watt high pressure sodium grow lamp from Hydroplanet is an excellent choice for a 2×4 grow tent:

• It is inexpensive. The light intensity is sufficient for two 4x4ft grow tents to be set up. Despite the fact that HPS grow lights have a bad reputation for being heat generators and electricity hogs, this little 150 watt type does not generate much heat and does not waste much electricity due to its modest size. Indeed, it consumes less energy than the LED lights that I’ll be describing later.

Using low-quality lighting is not my first option, and I strongly advise against doing so. In contrast, if you’re really short for cash, the 150 watts of power from this lamp will suffice. One thing I’d recommend to consumers of this Hydroplanet 150w HPS grow light is that they acquire a wing reflector separately rather than utilizing the hood type reflector that comes with the light. Using a wing-style reflector will allow you to distribute light more evenly across your 2×4 foot grow tent. The rest of the time, this grow light is a plug-and-play device.

Simply suspend this light between 18 and 24 inches above your canopy and you’ll be ready to go.

The Spider Farmer SF-2000 is a quantum board LED grow light that is both contemporary and efficient. This light has a coverage area of 2×4 feet and utilizes the same LEDs and driver as the HLG, although it’s priced a little less expensive than the latter. LM301B LEDs were used in this project, and the driver was provided by Mean Well, which is a high quality, industry standard driver. My 2×4 grow tent at home has one, and it looks and functions great. I highly recommend it. You can read the rest of my Spider Farmer review right here.

Take a look at the amount of light that the SF-2000 produces: The SF-2000 emits a spectrum that includes warm white (3000K), cool white (5000K), 660nm (red), and 760nm (blue) wavelengths (infrared).

See what people have produced under Spider Farmer grow lights in the following examples: These photos were taken from Instagram, and you can see the huge buds that the Spider Farmer proprietors have developed. These plants are nothing to be squeamished about.

SF-2000 Key Specifications:

• Will blossom in a 2x4ft area — a larger space is required for seedlings. It consumes 200 watts of electricity. An adjustable ballast is incorporated. LEDs and drivers of superior quality (Samsung and Mean Well)
• Price-performance ratio is the best available

Does the SF-2000 get hot?

It does generate some heat, as do all grow lights, but the amount is tolerable. Maintain proper air circulation and temperature control in the room where your 2×4 grow tent is positioned.

What height do I hang the SF-2000?

It generates considerable heat, as do all grow lights, but the amount is reasonable compared to other options. Maintain proper air circulation and temperature control in the room where your 2×4 grow tent is placed, and your tent will remain cool.

Designed specifically for use in 2×4 foot grow tents, the Green Sunshine Electric Sky ES300 is a high-end LED grow light. This is a high-intensity grow light with a spectrum that has been specially tailored. You’ll have to pay a premium in exchange for this. But it’s well worth the effort. Because the Green Sunshine Company feels that most grow light spectrums lack sufficient infrared, the ES300 generates greater amounts of infrared and red than is often seen in grow lights. The following is a breakdown of the colors: Blue makes up approximately 10% of the spectrum; green makes up 25% of the spectrum; red makes up 55% of the spectrum; and infrared makes up 10% of the spectrum.

• The University of Michigan conducted an experiment to see if the incorporation of green light is beneficial to plant development when compared to other typical spectrum makeups.
• According to the Green Sunshine Company, “With the unique high-dose of near-infrared light, huge blooms commence earlier, vegetation develops quicker, and the plant makes more effective use of light from what is known as the Emerson Effect.
• What you said piqued my interest immediately.
• Finally, take a look at the light intensity when it is suspended 18 inches over the canopy of a 2×4 foot grow tent: That is an astounding quantity of light spread throughout the whole 2×4 foot footprint of the grow tent.

ES300 Key Specifications:

• A 2×4 foot grow tent will produce flowers. Provides a broader area for seedlings to grow
• It consumes 300 watts of electricity and has dimming capabilities. Extremely high performance in a 2×4 configuration
• The heat sink frame effectively dissipates heat.

What Height to Hang The Green Sunshine ES300:

Because of the unique lenses on the ES 300, you can get the light extremely near to the plants without burning them.

The Green Sunshine Company specifically indicates that the light may be suspended as low as 12 to 15 inches above your canopy during the flowering phase, despite the fact that the intensity values above are from the normal 18-inch height. That’s quite an accomplishment.

Growers’ Opinions:

Green Sunshine grow lights have had consistently positive feedback, and I haven’t come across a grow light that has received more consistently favorable feedback as the Green Sunshine grow lights in my study. Please feel free to peruse the reviews on your own. Other than generally good remarks, gardeners have noted shorter vegetative development stages and higher-quality plants as advantages of using the product.

Growing in a 2×4 foot grow tent with the HLG 260 watt QB (quantum board) is a popular option for growers that don’t mind spending a few minutes putting it together. This is the XL variant, which means that the main board is longer than usual, allowing for greater space between the LED boards, which results in improved light uniformity. It is an excellent choice for a 2×4 space since you are receiving HLG quality and performance at a reasonable price with the HLG 260 watt quantum board. Assembling the light yourself enables them to sell the board at a lower cost than they otherwise would.

HLG 260 Watt QB XL Key Specifications:

• A 2×4 foot area is sufficient
• No soldering is required. Only a screwdriver and a wire remover are required. At 2.7 umol/Joule, it is extremely energy efficient
• It consumes 260 watts. Driver with dimming capability
• Included is a hanging kit. Color temperature of 3500K with red wavelength of 660nm (see below)

Here’s a look at the intensity when the light was tested in open air:

Keep in mind that this is an open-air test, and that when you install the HLG 260 watt QB into your grow tent, the reflecting walls will enhance the light intensity much higher than it already is. The temperature in the spectrum is 3500K, which is usually considered to be the optimal temperature for growing cannabis at all stages of growth. Additionally, the lamp has 660nm red LEDs, which guarantee that there is enough red light to support a vigorous blooming cycle.

After reading my lists, many growers contact me to seek for my advice. My personal preference for a 2×4 foot grow tent would be either the Spider Farmer SF-2000 or the Green Sunshine ES300, both of which are available on Amazon. Both of these lights are excellent choices, and I believe you will be pleased with any one. The HLG is also a very nice camera, but it faces stiff competition from the SF-2000, which is significantly less expensive. The Phlizon Linear Series PH-3000 received an honorable mention.

I don’t advocate the 150w high-pressure sodium lamp, although I do talk to folks who are on a limited budget from time to time.

Their power consumption is half that of high-pressure sodium or SMD LED lights, which is extremely beneficial to gardeners. Let’s take a look at the options that allow you to tailor your dimming. This series of SF has an improved dimming knobs switch that is designed to be user-friendly in design. Depending on the time of day, you may not require the same strength of light throughout the day, and so regulating it with the knob is a boon for both plants and gardeners alike. For industrial and commercial applications, the unified characteristics of multi-light are also particularly advantageous. All of the growth phases benefit from using lights, which are one of the most effective options for any situation. This product is highly recommended for those who are just starting off. This is because the lights include full-spectrum lighting, which include colors such as white, blue, red, and infrared, in addition to other colors. The white LED emits 3000K of light, while the blue, red, and infrared LEDs emit 5000K, 660nm, and 760nm of light. 660nm red and infrared light have a beneficial effect on the blooming stage. A greater yield in a shorter amount of time is what indoor gardeners strive for. As an added bonus, these LED lights are safe for the plant’s wellbeing because they are made from natural materials.

SPIDER FARMER or MARS HYDRO – Which one should you buy?

I discovered a statistically significant difference between SPIDER FARMER and MARS HYDRO. Both of the LED lights give natural lighting, which allows the plants to thrive on their own. The MARS HYDRO, on the other hand, only covers the white light spectrum, which may be insufficient for plant development. It may have an adverse effect on plant growth since full-spectrum light can support all phases of plant development. If the cost of SPIDER FARMER is not an issue for my readership, I would recommend that they acquire it.

Final words

Finding the finest LED light for a 42 grow tent proved to be a difficult task for me. However, gardening is my passion, and I like assisting gardeners by providing them with useful information. If you are here to acquire the LED light, I would recommend that you choose any of them since they will produce the maximum output, especially the SPIDER FARMER, when they are turned on. If, on the other hand, you are a complete newbie, you should not miss any topics from this section. I attempted to provide an answer to the most often asked question by gardeners.

What Size Grow Light Do I Need? (The Simplest Way To Figure It Out)

Trying to figure out which LED light would be the ideal for a 42 grow tent proved to be difficult. However, gardening is my passion, and I like assisting gardeners by providing them with helpful information. If you are here to acquire the LED light, I would recommend that you choose any of them since they will produce the maximum output, particularly the SPIDER FARMER, when they are turned on.

For those who are new to the subject, there is no need to skip any topics. Gardeners frequently ask me questions, so I attempted to provide a response to their most common one. You’ve done a great job going over this tutorial!

How To Determine The Size (And Number) Of Grow Light(s) You Need

I’ll start with high pressure sodium and metal halide lighting, then go on to compact fluorescent, then LED, and lastly fluorescent.

What Size HPS And MH Lights Do I Need?

High pressure sodium and metal halide lighting are the most straightforward types of lighting to understand (along with CMH below). There are two approaches that you can take.

By Coverage Area

It is simple to determine which light(s) will best cover your grow space if you know the size of your grow space (for example, the size of your grow tent). According to the most commonly used MH and HPS bulbs, the following approximate maximum coverage areas may be achieved with these wattages:

• 150 watts: 2 x 2 feet (or 4 square feet)
• 250 watts: 2.5 x 2.5 feet (or 6.25 square feet)
• 400 watts: 3 x 3 feet (or 95 square feet)
• 600 watts: 4 x 4 feet (or 16 square feet)
• 1000 watts: 5 x 5 feet (or 25 square feet)
• 1500 watts: 5 x 5 feet (or 25 square feet)
• 2000 watts: 5 x 5 feet (or 25 square feet)

You should be able to determine which size light is appropriate for you and how many lights you require based on this information. If all else is equal, 600 watt lights are the most efficient (meaning they produce more light per watt of power consumed) and 1000 watt bulbs are the second most efficient, so you should always check to see if they would work in your space first. Consider the following scenario: you have an area that measures 10 by 20 feet, or 200 square feet. That is completely divisible by 4 (the 150 watt bulb) or 25 (the total number of watts) (the 1000 watt bulb).

• The eight 1000 watt bulb option is far superior.
• Although the area is not exactly divisible, 200 divided by 16 gets you 12.5, which means you would only need to utilize 12 or 13 fixtures to make them all fit in the space.
• One thing to keep in mind is that this is based on the maximum coverage regions available for each bulb power.
• If you want to provide your plants enough of light in order to increase yields, the following approach makes it crystal apparent and provides greater outcomes than the previous one.

By Wattage

The alternative method for determining your MH and/or HPS lighting requirements is to look at the wattage requirements. Cannabis, for example, requires between 30 and 70 watts per square foot of canopy to thrive, making it an ideal plant for growing indoors. I would recommend a minimum of 50 watts per square foot of floor space. If money is not a problem and heat is not a concern, increase the power to 65 watts per square foot. Let’s have a look at the previous example once again. The one with a 200-square-foot floor space, to be precise.

In such case, ten 1000-watt lights (10,000 / 1000 = 10) or seventeen 600-watt bulbs (10,000 / 600 = 16.67, which we round up to 17) would be required.

By working backwards, we can see that the preceding technique would provide coverage of 40 watts per square foot (eight bulbs each at 1000 watts = 80,000 total watts divided by 200 sq ft area = 40 watts per square foot).

Despite the fact that there is still plenty of light, we would achieve better outcomes if there was more light. You may check my reviews of the best bargain HID kits if you’re not sure which brand is the best choice.

What Size CMH Grow Light Do I Need?

Because there are just two typical wattages available: 315 watts and 630 watts, ceramic metal halide is much simpler to figure out than incandescent (which is a fixture with two 315 watt bulbs in it). One way to think about them is to examine the 315w bulb, which is comparable to 600w of MH or HPS light, and the 630w twin bulb fixtures, which are equivalent to 1000 watts of MH or HPS light. This implies that a 315 watt light will cover up to 44% of the area, while a 630 watt fixture will cover up to 55% of the area.

Check out my reviews of the best-value ceramic metal halide lighting kits if you aren’t sure which type of light you want.

How Many Watts Per Square Foot For LED Grow Lights?

In order to decide what size LED light(s) they require, most people use the wattage per square foot method, however this is not the only one. In addition, it is not the most exact method, but it is an excellent balance between accuracy and simplicity. Simply put, selecting how strong an LED grow lamp to purchase and how many of them you require is the most difficult task of all when it comes to growing plants under artificial light. This is owing to the wide range of lights available, as well as the fact that most manufacturers flat out lie about the specifications of their products.

In this case, there are three options to examine.

Using The Coverage Area Provided By The Manufacturer

When purchasing lights, most manufacturers disclose the coverage area of their lights, which you may use to determine which light will be able to adequately cover your grow space. Isn’t it nice and straightforward? If only everything were that simple. Unfortunately, many manufacturers (mostly Chinese, but also a significant number of American companies) overstate the area that their lights will successfully cover. The coverage area for a low-light-requirement plant (and not one with a high requirement, such as marijuana) or the coverage area for vegging, which is always bigger than the coverage area for blooming, are examples of what they could tell you to do.

Unfortunately, I do not have a decent answer for this problem at the moment.

If you’re looking for information about lights that I haven’t examined, you’ll have to go online.

Using The Wattage

If you want to grow a plant that requires a lot of light, you should aim for 30 to 40 watts per square foot of canopy area. Once again, there is a major issue to contend with. The majority of LED manufacturers provide both an actual wattage and a theoretical wattage (what the light would consume if the chips were all driven at full power, which they never are). Important! It is preferable to use real wattage for this calculation. This need a little investigation in order to determine the real wattage of a light bulb.

• Many Chinese manufacturers do not even employ theoretical watts in their products.
• Roleadro’s 2000 watt light, for example, only consumes 230 watts in reality (Roleadro is one of the absolute worst offenders when it comes to blatantly making up numbers).
• They frequently bury it in the bottom of the page, but it is virtually always visible at the top.
• Consider the following illustration.
• 6000 watts total would be required to illuminate that area with LED grow lights if we were to go for the lowest possible wattage per square foot of 30 watts per square foot of light.
• This lamp has an actual power of 615w, therefore if we used 10 of these, we would have a total of 6150 watts.
• Consider the following scenario: you have a 3×3 grow tent.
• At 30 watts per square foot, you’d need a total of 270 watts to cover the area.
• As a result, to illuminate this space, you would want an LED grow lamp with an actual wattage of 270 to 360.
• As a result, the efficiency of the light is not taken into consideration with this technique.
• However, the actual output will vary widely from one manufacturer to the next, and wattage is regarded as a decent indication for the quantity of light a fixture would offer.

Phlizon lights are simply more energy efficient than traditional lights. As a result, we arrive at the most accurate method: relying on the original output.

Using The Output

While this approach is the most accurate, it is also the most difficult to utilize since many manufacturers do not publish a great deal (if any) of useful information on the output of their lighting fixtures. This is especially true when it comes to Chinese-made products. Even if they do offer output information, they frequently just take a reading dead center underneath the light, which is where the output is at its most powerful, rather than everywhere else. They do not provide readings for the remainder of the coverage area, which is frequently due to the fact that the light is quite feeble around the outside of the region.

I’m sure you’re curious in how output is assessed and what level of output is considered satisfactory.

It is measured in units of micromoles per square meter per second and informs you how much light is present in the wavelengths that plants employ for photosynthesis.

Plants should receive between 300 and 600 umol/m2/s during the vegetative stage and between 600 and 1000 umol/m2/s during the bloom stage in order to get best results.

You want to acquire at least 100 umol/m2/s, but preferably more.

A PPFD footprint will be provided by reputable manufacturers (also referred to as a PAR footprint or a PAR chart).

Most of the better lights will not have sky-high readings in the centre (and hence much lesser readings around the perimeter), but will instead have decent readings all across the place (even if the manufacturer just supplies the number for the middle).

What Size Fluorescent Grow Light Do I Need?

Fluorescent lights are only useful for a couple of plants at a time. They become inefficient if they are used for any longer than that. This article explains how to calculate the number of fluorescent bulbs you will require. Instead of reading that, just know that you’ll need between 60 and 100 real watts per square foot of growing space to have a good yield.
