r/microgrowery – How many Watts for 2×2.5 grow tent?
Hello, I recently finished my first grow using a 300W LED light that I purchased from Amazon, and I only harvested 2 oz from the three plants that I produced. When I blogged about it on this site, practically everyone assumed that the light was the source of the problem. I’m currently looking into purchasing a new one and am considering this 1000 Watt model. What are your thoughts, everyone? A 2×2.5-ten would require about how many watts would you recommend? Is 1000 watts of power excessive? In addition, I will most likely be doing 1-2 plants this time.
To make a comment, you must first log in or create an account.
Even at 1000 true watts, that tent would be overpowered, but 300 true watts would be excellent.
This is at the second level.
- In level 1, pay close attention to the real power consumption of LEDs.
- In order to grow successfully with LEDs, you need at least 50 true watts per square foot of growing space, and preferably more for blooming.
- Cobs/quantum is something you can handle at 30.
- You Americans need to learn to be kinder to the Chinese, since they are ridiculously low costs.
- The day before, I went for a run in the same size tent and drew 8 oz.
LED wattage for 2x2x4′ & a few more questions
You are currently using an out-of-date web browser. It is possible that this or other websites will not show correctly. You need either upgrade your browser or switch to another one. My first hydroponics grow is now in progress. Is a 1000-watt grow lamp sufficient for two self-flowering plants in a 2x2x4-foot greenhouse? The off brand is being replaced by a Mars 1k Watt, and the off brand will be kept as a back-up power source. The plan is to have one tent and one grow box, with a couple of tents in flower and a couple of grow boxes in vegetables.
- Are there any restrictions on how long I can take a one-week hit and still use the tent to dry the harvest?
- With a 400 CFM exhaust and a carbon filter, it’s a powerful machine (not using yet).
- If I require a fan controller, could you kindly provide a link to a reasonably priced model?
- Is it possible to dim it?
- That doesn’t seem worth it to me; instead, I’d use a lower wattage to produce larger plants.
- Make certain that the room is completely dark and that the temperature and humidity are maintained.
- With only 4′ in height, this is a little space.
- Wishing you the best of luck I’m only getting started, but I’ll be able to upgrade to a Mars LED and a larger tent later.
The first 4 feet are for Veg, and the autoflowers I chose are high yielding, highly potent, and short in height. Perhaps with this proof of concept arrangement, I will be able to top the first run and keep it short. A sea of green with indica might be possible if you wanted to go that route.
Air speed controller that is active. It may be a little more expensive, but it will not cause your extractor fan to make strange noises as the cheaper/knockoff brands do. I’m getting a Mars 300 designed for a 2×2 in the mail. How far away is this one from being a seedling? I’ll take measurements of the ceiling and, when the time comes, I’ll get a 4’x4’x80″ sheet of plywood. I know that after I have everything planned up, I’m going to want the maximum legal (6 blooming and 6 veg) haha Thank you, and please accept my apologies for the basic inquiries!
- How far away is this one from being a seedling?
- 15-22 inches for a 300-watt LED light source Please feel free to ask as many questions as you need, brother, that is exactly what this forum is for!
- I need a lower wattage than the 1000w I now have so that I can go closer to the seedlings.
- My first hydroponics grow is now in progress.
- The off brand is being replaced by a Mars 1k Watt, and the off brand will be kept as a back-up power source.
- When I harvest the vegetables, I transplant the seedlings or clones into a grow box.
- (This product has been carbon filtered.) At the bottom of the tent, I’ve installed a 200 CFM intake inline fan, which seems to be running very hard.
Is that a lot of airflow for seedlings to handle?
Thank you for this wonderful forum!
Generally speaking, you’ll need around 30-40 watts per square foot.
The true amperage draw, or the real line wattage, of your 1000-watt light should be labeled somewhere on the fixture.
While it may be using 1000 watts, it would equate to around 8 amps, which is far too much power for a 2×2 tent to handle!
Also, that fan is probably running at too high of a speed, and you may slow it down by using a variable speed line control like The Speedster.
I am running 450 watts of genuine COBs and a blurple in a 10 square foot tent, which equates to 45 watts per square foot, just for the purpose of comparison.
I’m using a 4 inch “duct booster” style fan to exhaust the tent, and it appears to be working just well so far.
It is around 62 degrees outside, 72 degrees indoors, and 55 percent relative humidity when the lights are turned on.
If you’re wondering how I got to 450 watts, I just added one additional 100 watt cob after this picture was shot.
52 Amp.52 Amp x 120 Equals 62.4 Watts in actuality.
If I were you, I’d be calling BS on the light requirements, but what do I know?
In addition, I have a forthcoming 3x3x6′ tent as well as two decent fan speed controllers on the way.
This is the light that is now on.
The MARS HYDRO TS 600W LED Grow Light is a 2×2 ft Sunlike Full Spectrum Led Grow Lamp that is ideal for growing plants.
Given that it is described as a switchable 100-200-watt light at the bottom of the advertisement, it should be the perfect size for your tent.
A large number of individuals who run the bloom and veg switch both on to blossom, thereby doubling the power use.
I’m currently consuming 2 Critical Kush Auto, which are just stunning.
You can either use a clamp on style amp reader, which surrounds only the hot lead and reads using induction, or you may disrupt the hot circuit with the leads (which is slightly risky and generally breaks the multimeter fuse at these amps).
Or perhaps it has a dimmer, and you caught on to what I was saying.
You just need to plug in the KillAWatt and connect your device to it, and you’ll have access to a variety of amp/watt/kilowatt information at the click of a button.
Working with computers and writing about them for more than 30 years came in helpful when calculating total pull from the wall and making sure not to underpower rigs by utilizing a modest power supply.
It’s strange that it’s so low.
My Mars light is rated at 300 watts, yet it consumes 306 watts.
9 amps, 200 watts, about 1.8 amps And, depending on the setting, yours should consume between 100 and 200 actual watts of power.
A 300-watt equivalent lamp from China, perhaps 12×12″, would be my best guess for the shaky light.
They just legalized medicinal marijuana here, and you may grow up to 6 blooming plants and 6 clones per grow license, so I’m getting ready for temperatures in the 60s and 70s.
Tents are available in two sizes: 4 square feet and 9 square feet.
Advanced hydro nutes, a pH meter, a ppm tester, and all the other accoutrements are included.
Growing marijuana became economically viable when the price of a gram dropped to 10 dollars.
It’s not a problem.
I was able to get beautiful pink Blueberries from it, but the same buds with 3.1 K cobs remained green.
Keep the blurple and put it on in addition during blossom, as it will bring a lot of red for the flowering cycle.
Fortunately, I can show up at a friend’s house and extract 4 clones and move them, so it is not too hard.
In that case, Buzz62, are you cloning the photoperiod blueberry?
I have photoperiod seed, but I’m trying to dial it in with auto.
Is it possible to clone generations indefinitely, or is it possible to clone generations indefinitely? I’m thinking about planting half hydro and half soil out of the gate, so that if I have to increase the amount of hydro, there will still be produce.
How Many LED Watts Are Required Per Square Foot of Grow Space?
*This article was last updated in May 2018. Are you a newcomer to the world of LED cultivation? If this is the case, the charts below will assist you in determining how much energy (measured in watts) your plants require to blossom. Disclaimer: Wattage is a legacy of the days of high-intensity discharge (HID) lamps (MH and HPS). The coverage area of a fixture or the utility of an LED grow light should not be determined by the wattage of the fixture or the LED grow light. Using wattage as a simple technique of estimating the optimal fixture size for your grow should be limited to the most basic of situations.
PPFD (and spectrum) are essential components of a good grow when used in conjunction with the appropriate spectrum for your plant type and development phase.
The term “wattage” in this article refers to the amount of electricity that is pulled from the wall, not to the amount of electricity that is drawn from the LEDs, which is normally the product of the maximum LED wattage multiplied by the number of LEDs specified by the manufacturer.
The LED grow light, on the other hand, may only consume 500 watts when connected to the wall.
It is critical to note that the amount of actual watts that you will use for your grow will vary based on the following factors:
- Plants that require a lot of light, such as tomatoes, peppers, and other vegetables
- Plants that require little light, such as herbs and leafy greens (such as basil lettuce)
- There is a significant difference in the quantity of light required by seedlings, vegetative, and blooming plants.
Watts per square foot
For blooming, the typical LED grow lamp consumes around 32 watts to cover 1 square foot. This is in stark contrast to a conventional HID lamp, which consumes 40 watts per square foot (assuming a 5′ x 5′ space or a coverage area of 25 square feet). The use of a HID in a 4′ x 4′ area will increase the power coverage to 62.5 watts per square foot (psf). (The energy savings that growers may expect from employing LED grow lights instead of high-intensity discharge lights is around 38 percent.) This energy savings figure solely includes the savings that farmers realize as a result of utilizing LED lighting fixtures.
For example, depending on the size of the setup and the temperature of the surrounding environment, less ventilation and air conditioning may be employed, or it may be altogether avoided.
More energy-efficient LED grow lights will consume fewer watts to produce the same amount of light that a less energy-efficient LED grow light would provide.
As a result, as previously said, wattage is not the most accurate tool for determining how strong of a grow light you require for a specific coverage area under consideration.
LED Wattage Chart Explanation
The wattages indicated below are based on the assumption that you are blooming your plants. If you’re growing vegetables, you might want to consider reducing your wattage by 50% because vegging plants only require roughly half the amount of light that flowering plants do. As is always the case, following the manufacturer’s advice is the best course of action.
Using the charts
The following columns will be included in each of the charts:
- Plants to be cultivated in a certain area The area covered by a certain number of plants in terms of square footage
- The recommended LED wattage is based on the quantity of plants being grown in the given space.
For blooming, assume a wattage of around 32 watts per square foot (real LED wattage). Smaller yields may be associated with lower wattage, whereas bigger yields may be associated with higher wattage.

How many watts for 2×2 grow tent?
The size varies since it might be determined by the number of plants that you need to cultivate. Small grow tents are commonly available in sizes of 2×2, 2×4, 3×3, and 4×4. The amount of space available in your growing area might also be a consideration. For example, it is preferable to cultivate one plant every square foot of available space. Indoor gardeners often leave at least 2 inches between pots or containers in order to avoid the plants from becoming suffocated. Keep in mind that the size of your grow tent should be modest enough to fit anyplace in your grow space without overwhelming the space.
What Is The Purpose Of A Small Grow Tent?
Essentially, a tiny grow tent is an enclosed, self-sustaining structure that allows gardeners to grow plants within their homes. Using a micro grow tent, an indoor gardener may maintain complete control over environmental elements like as light intensity, humidity, and temperature, all of which are critical to the growth and productivity of their plants. In general, a grow tent should be reflective, waterproof, light-proof, strong, and non-toxic to ensure that it is effective. Aside from that, it must be constructed with observation windows and several vents.
The capacity to manage growth conditions also contributes to its ability to generate high germination rates.
Cloning– Cloning a mother plant is more easier than growing seeds, which is why it is often used.
However, a 2×2 or a 4×4 grow tent is still required for this strategy.
Blooming– A 3×3 or 4×4 grow tent allows gardeners to control the amount of light they get in order to commence flowering. If you have 400-watt to 600-watt grow lights, you can even accommodate 4-6 full-sized plants in your growing space.
Watts per square foot
For blooming, the typical LED grow lamp consumes around 32 watts to cover 1 square foot. This is in stark contrast to a conventional HID lamp, which consumes 40 watts per square foot (assuming a 5′ x 5′ space or a coverage area of 25 square feet). The use of an LED grow lamp in a 4′ by 4′ space will increase the power coverage to 62.5 watts per square foot. (The energy savings that growers may expect from employing LED grow lights instead of high-intensity discharge lights is around 38 percent.) This energy savings figure solely includes the savings that farmers realize as a result of utilizing LED lighting fixtures.
- For example, depending on the size of the setup and the temperature of the surrounding environment, less ventilation and air conditioning may be employed, or it may be altogether avoided.
- More energy-efficient LED grow lights will consume fewer watts to produce the same amount of light that a less energy-efficient LED grow light would provide.
- For 2’x2′ or 3’x3′ grow tents, the ECO Farm 240W QUANTUM BOARD LED GROW LIGHT is ideal.
- THE MOST IMPORTANT FEATURES

What Size Grow Light Do I Need? (The Simplest Way To Figure It Out)
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.
- Herbs and lettuce, for example, are examples of plants with minimal light requirements since they do not blossom.
- 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.
- Alternatively, you can measure the plant (s).
- It is time to get started once you have obtained those three pieces of information.
- 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.
- 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.

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.
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
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?
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 products. In particular, this is true for Chinese-made products. They seldom offer output information, and even if they do, they frequently only take a reading in the center of the light, which is where the output is the strongest. Because the light is so feeble outside of the coverage area, they are unable to provide you with readings for the remainder of the area covered by the device.
- If you’re like most people, you’re curious in how production is assessed and what level of output is considered satisfactory.
- Photosynthesis is measured in units of moles of light per square meter per second, and it informs you how much light is present at 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 the best possible outcomes.
- You want to acquire at least 100 umol/m2/s, but ideally more.
- A PPFD footprint will be provided by a reputable manufacturer in most cases (also referred to as a PAR footprint or a PAR chart).
- The best lights will not have sky-high readings in the centre (and, as a result, considerably lesser values around the outside, even if the manufacturer just supplies the figure for the middle), but will have decent readings all across the spectrum.
In an ideal world, the concentration of umol/m2/s will reach or exceed 100 umol/m2/s even in the most remote corners of the coverage region.
