What Size Light For 2X4 Grow Tent

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.

The Hydroplanet 150w HPS grow light is not my first choice, and I don’t recommend scrimping on lighting unless absolutely necessary.However, if you’re really tight on cash, 150 watts from this light will suffice.The one thing I’d recommend to buyers of this Hydroplanet 150w HPS grow light is to purchase a wing reflector separately rather than using the included hood style reflector. In addition, the wing-style reflector will distribute the light more evenly around your 2×4 foot grow tent. Aside from that, this grow light is simple to set up and use.

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

a 2x4ft area will enough for flowering; a larger space will suffice for seedlings It draws 200 watts of power. Includes a dimmable ballast; LEDs and drivers of excellent quality (Samsung and Mean Well); Excellent performance at a reasonable cost.

What height do I hang the SF-2000?

It is safe to hang this light at a height of 18 inches throughout vegetative and blooming stages, and at a height of 28 inches for seedlings. If you don’t have enough room to raise the light, you may always dim it; however, you’ll have to unscrew the driver from the board in order to get to the dimming screw, which is located on the bottom of the driver, which will need some effort.

For veg and blooming, it is safe to hang this light at 18 inches, and for seedlings, it is safe to hang it at 28 inches. Even if you don’t have enough room to raise the light, you may always dim it. To do so, you’ll need to detach the light driver from the circuit board in order to access the dimming screw, which is located on the bottom of the driver.

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.

  1. 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.
  2. 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.
  3. What you said piqued my interest immediately.
  4. 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.

Your cannabis plants will undoubtedly flourish under the illumination provided by this grow light!

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.

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.

It’s a little more expensive, but it’s another good option for a 2×4 foot grow tent. 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. If such is the case, you can choose one of those options.

What makes the best grow light?

Let’s look at some of the most significant factors to consider before making a purchase from the vast array of forms, sizes, wattages, pricing, and other characteristics that can be discovered on the Internet to assist you in making your decision.

  • The price will be determined mostly by the quality of the manufacturing, but it will also be determined by some alternatives that can provide a significant benefit to the user. For the panels, certain versions have fans that are connected to aluminum heatsinks, as well as the option of chaining many panels together in the same installation. In the case of lights, the number of heads, the number of switches, and the capacity to alter the illumination intensity are all factors that might impact the price. With regard to bulbs, the quality of the heatsinks is mostly responsible for the difference in performance. Make sure that the power of your installation corresponds to your requirements. Indeed, the situation will be extremely different for a little bonsai or a palm tree that is more than a meter tall. The length of the equipment’s warranty duration is also a significant consideration in the choosing process. The longer it is, the greater trust the manufacturer has in the origin of the parts, as well as in the production and testing processes
  • The shorter it is

What makes the best grow light is a matter of opinion.

1. The light flux supplied by LED

It’s important to understand that not all plants have the same requirements or tolerance levels when it comes to light flux. This is due to the fact that each species has a limit amount of light that it can absorb before suffering harm. Unfortunately, determining this value is challenging, and it will be essential to rely on studies and research conducted on a variety of plant kinds to arrive at a conclusion on this issue.

Visit the Conservation Nature website and, in particular, their plant encyclopedia to learn about the varied needs of plants (sun/partial shade/shade) in order to get an estimate of the amount of exposure required by each plant.

2. The light spectrum emitted by the lamp

When it comes to selecting horticulture LEDs, understanding the notion of the light spectrum is critical. Essentially, these are the set of wavelengths that are released by a source of light, whether it be the sun or an artificial light source. The portion of the electromagnetic spectrum that is visible to the human eye ranges from 400 nm to 700 nm. Ultraviolet is defined as wavelengths below 400 nm, and infrared is defined as wavelengths over 700 nm. When all of the wavelengths are combined in the same luminous flux, the light looks white to humans; but, when the wavelengths are separated, the light is interpreted by our eyes as having different hues.

3. Power supply

In terms of their operation on 230 volts, LEDs are unique in that they cannot be used directly on a residential electrical network. When purchasing horticultural LED panels, it is advisable to get a type with a distant power supply rather than an integrated power supply in order to avoid the heat created by the power supply accumulating with the heat generated by the LEDs.

4. The cooling system

In terms of their operation on 230 volts, LEDs are unique in that they cannot be used directly from a residential electrical network. Rather than opting for an integrated power supply for horticulture LED panels, it is recommended to go with a type that has a distant power supply, which prevents the heat created by the power source from accumulating with that generated by the LEDs. The active dissipation system is comprised of fans that take hot air from around the bulbs and replace it with cooler air to achieve the desired result.

The passive dissipation, as the name implies, is not dependent on the existence of any moving parts, but rather on the presence of a piece of metal that is in direct contact with the heat source (that is to say, the lamps).

5. Noise problems

An additional drawback of using a low-quality lighting equipment is that it might occasionally emit unwanted hissing or noise. In conclusion, it can be stated that the poorer the quality of the lighting device, its components, and the manufacturing process, the greater the likelihood of noise pollution occurring during operation.

6. Sealing of the lighting system

A certain amount of humidity and temperature are required by some species of plants (carnivorous plants for example). As a result, it is strongly advised that lighting equipment that is both functional and, more importantly, durable under these circumstances of operation be selected. *** More information may be found at: Growing Plants Under a Desk Lamp Is A Scientific And Effective Method of Growing

How can you rate the quality of Led grow light?

What criteria do you use to evaluate the quality of an LED grow light?

1. The Efficiency

Ideally, the illumination provided by an LED grow light should be comparable to the lighting provided by the Sun. These light sources not only allow plants to develop through photosynthesis, but they also stimulate fruiting and blooming in response to the length of time that the light is available. Plants will soon deteriorate (yellow leaves) and perish if they do not receive enough light. Carbon dioxide and water from the atmosphere are converted into carbs in this process (sugars).

Chlorophyll is a pigment that absorbs the red and blue components of light and is responsible for the green color of plants’ leaves. The success of your hydroponic system or soil depends on the availability of light.

2. The Intensity

Reflectors are an excellent choice for increasing the intensity of horticulture lighting. Some bulbs, such as high-pressure sodium and mercury-vapor lamps, will require a ballast. In this instance, Culture Indoor provides you with pre-designed interior luminaires that can be applied to any surface without the need for a custom design. Find CFL kits or HPS / MH kits on our website. What is the best way to measure LED grow light? The total wattage of LED grow lights may be used to determine the intensity of the light produced.

  • Another solution is to use lamps to illuminate the plants’ surroundings.
  • PAR is measured in PAR units.
  • The quantity of PAR light (photons) reaching the surface of the plant per second is measured by the photons per second (PPFD).
  • Plants grow more efficiently under G8LED grow lights because their PAR (photon absorption rate) is between 600 and 1700 mol / m2 / s.
  • Increase the number of trichomes on your plants to make them healthier and more strongly blossoming.

3. The Range

The type of LED garden lights you choose will be determined by the surface you wish to illuminate. The lens angle of LEDs, which can range from 20° to 160°, determines the amount of light that they emit and reflect. The greater the angle of attack of the lamp, the greater the area covered by the lamp. However, because the photon flux is dispersed across a wider surface area, the illumination intensity will drop as a result of the reduced illumination intensity. Wide lens lights may be quite beneficial for seedlings and early shoots since they can be put closer to them while still providing a little amount of additional heat to the plants.

As a result, if at all feasible, determine the precise size of your space and select the lights that will best meet your requirements.

4. The ratio of different wavelengths/colors of light

When it comes to choosing LED garden lights, understanding the notion of the light spectrum is critical. Light sources, whether natural or artificial, emit a spectrum of wavelengths that are known as their color spectrum.

The portion of the light spectrum that human eyes can perceive is between 400 and 700 nanometers in wavelength. We are talking about ultraviolet light when the wavelength is below 400 nm, and infrared when the wavelength is above 700 nm.

  • Use of “blue” light, with wavelengths ranging from 400 to 500 nm, to the greatest extent possible throughout the growth of our flora

If you provide enough green light to plants during this period, you may see that they have more leaves, stronger roots, and shorter internodes than plants that have not been exposed to enough light. This is due to the fact that the plant does not have to extend these stems in order to receive the maximum amount of light.

  • When the plants are in the blossoming stage, they mostly require red light. There are wavelengths ranging from 620 to 780 nanometers in the spectrum.
See also:  Where To Place Fans In Grow Tent

They mostly employ red light during the blooming period. There are frequencies ranging from 620 to 780 nanometers in the spectrum;

  • LED grow lights (mainly in the blue spectrum)
  • Flowered LEDs (primarily in the red spectrum)
  • LEDs in a mixed configuration (with specified blue and red distribution)
  • LEDs that can be customized (you may select from a variety of hues)

According to industry standards, the majority of commercial horticulture LED panels or lights feature a variety of hues with a red to blue ratio of around 80 to 20 percent. This is the finest balance since it will work in all instances while minimizing the need for excessive expenditures in some cases. It is feasible to select lamps that disperse the full light spectrum, so guaranteeing that plants always receive the wavelengths they require at the appropriate time of year. Increased consumption will be the chosen partner in this case.

Frequently Asked Question

It might be difficult to figure out what size grow light you need for your plants. A variety of elements come into play, like the sort of lighting you prefer, the plant(s) you are growing, the size of your grow space, and so on and so forth. In this essay, I break down the problem and attempt to make it as straightforward as possible. Before you begin, you must determine the light requirements of your plant(s), the sort of lighting you intend to employ, and the size of your grow space. 1. Requirements in terms of lighting When it comes to the light need, all you really need to know is whether it has a high or a low requirement for light.

  1. Herbs and lettuce, for example, are examples of plants with minimal light requirements since they do not blossom.
  2. The Kind of Lighting To be on the safe side, use fluorescent lights if you just have one (or maybe two) plants and LED or CMH lights otherwise if you are unclear which sort of illumination you will require.
  3. 3.
  4. Alternatively, you can measure the plant (s).
  5. It is time to get started once you have obtained those three pieces of information.
  6. In order to determine what size of light you require and how many lights you require, if you require more than one, follow the instructions.

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

It might be difficult to figure out what size grow light you need for your plant. A variety of elements come into play, like the sort of lighting you prefer, the plant(s) you are growing, the size of your grow space, and so on and so on. Throughout this paper, I attempt to simplify as much as possible the subject matter. There are three things you must know before you begin: the light requirements of your plant(s), the type of light you intend to use, and the size of your grow space. 1. Requirements in terms of light The only thing you really need to know about the light need is whether it has a high or low requirement.

  • Herbs and lettuce are examples of plants that require little light since they do not blossom.
  • The Lighting System To be on the safe side, use fluorescent lights if you just have one (or maybe two) plants and LED or CMH lights otherwise if you are unclear which sort of illumination you require.
  • 3.
  • Alternatively, the plant might be measured (s).

It is time to begin once you have obtained those three pieces of information. Below, you’ll discover information about the kind of lighting you want to utilize. In order to determine what size of light you require and how many lights you require if you require more than one, go to the instructions.

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).

  1. The eight 1000 watt bulb option is far superior.
  2. 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.
  3. One thing to keep in mind is that this is based on the maximum coverage regions available for each bulb power.
  4. 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.

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

In order to decide what size LED light(s) they require, most people use the watts per square foot method, however this is not the only one. Not only that, but it is also 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 lights. As a result of the wide range of lighting options available and the fact that the majority of lighting companies intentionally misrepresent their products’ specifications, this is the case.

There are three techniques that I would consider using in this situation.

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.
