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.

Lighting for a 5×5 Grow Tent?
- Date of joining: March 5, 2019 Messages:25Likes Received:3 Hello, I’m going to make the decision to purchase my first grow setup. My research has led me to believe that there is a clear solution to how to light a 5×5 grow tent, but I have yet to come across one. My intention was to utilize two LEDs with a combined power of 1,000 watts. Thoughts? Thanks

Date of joining: June 8, 2016 Messages:15,873 Likes Received:11,262 Using qb’s, you can outfit a 5×5 with half as much power as a 4×4. The cost is significant, but depending on where you live and local power rates, you’ll save $50 to $100 per month on electricity use over 2000 watts. Not to mention the fact that the quality is, in my opinion, superior. I’m assuming you’re referring to rated watts. Having said that, I am not aware of a single LED grow lamp with a “1000w” rating that is worth purchasing.
- Their real watt total has been as low as 130 watts in my experience.
- For a 5×5, I’d want to run 9 qb96s and 3 meanwell HLG-320h-54a drivers for a total wall draw of around 1100 watts when the system is fully loaded.

- Date of joining: June 8, 2016 Messages:15,873 Likes Received:11,262 I believe that many individuals enter a 5×5 grow room without realizing that this is actually a very large place for a personal size flowering space. A 5×5 may produce 3-4 pounds of fruit or more, yet they require a lot of energy to be filled. Most will yield far more bud than is required for a regular home grow. A 4×4 is a better choice for a personal-sized area. It’s around 70% smaller, which means you can furnish it with significantly less power. They’re more effective than we are. In those, a power output of 500-650 watts is enough. I’ve gained 2 pounds in a 4×4 container. For me, a harvest suffices as a sufficient amount of food. As long as you have a 4×4 vegetable garden going at the same time, you may harvest every ten weeks and just shift the next veg plants into the flowering area every time you clean it out of the veg garden. There will be many more harvests every year, as well as the potential to have two lighting systems, one targeted toward flowers and another aimed toward vegetables. Vegetables use less than half the energy per square foot as do fruits and vegetables. 3×3 is actually a good size for most people, and you can fill one of those with just approximately 350 watts of electricity. Once you have some experience, you may earn more than a pound during harvest, which I absolutely agree with. I have a 3×4, and I was thinking today that a 3×3 might have been preferable for the situation

Date of joining: June 8, 2016 Messages:15,873 Likes Received:11,262 When you’ve never grown before, 5×5 seems like a little space, but it’s actually very large for a blooming area for a personal size grow. I drive 4x4s, which are a little huge, but I’m a big pothead, and my wife is as well, so we require double the amount of space as the average smoker. I prefer to have enough money to be able to give it away without having to think about it.
That is something you can accomplish in a 4×4. While I’m not trying to be derogatory, a 5×5 is actually only required if you want to have enough inventory to sell. It’s far too big for a pair or even a single person to comfortably fit in.

Each single square foot takes an additional $50 in power per month to fill with flowers and hundreds of dollars in additional lights for each additional square foot. Three-by-threes are extremely efficient. You can fill one with less than $300 worth of absolute top-of-the-line LED lights and be quite content with a power consumption of roughly 350 watts. Even in more expensive places, you’ll only pay $35 for your electricity. Date of joining: March 5, 2019 Messages:25Likes Received:3 Thank you for all of the information
- I think I’ll have to rethink my plan in light of this. I understand that 5×5 is a large size, but I would rather have too much merchandise than not enough. Prices around here are really high, such as 1,000 for a qp in my network of acquaintances, so I’m really hoping to avoid running out of money before the holidays. With the 5×5, I assumed that if I grew too much, I’d just have to wait a little longer before starting the next grow. In addition, I reasoned that the increased size would help protect me from myself while still ensuring a good harvest, given that I had never done this before. But it’s possible that I’m thinking backwards here? I’ll have to dig into the concept of eternal growth a little further. Is it possible to combine a 3×3 veg room with a 4×4 floral room, or do they both need to be the same size? Is it possible for the two independent tents to share the same ventilation system as well?

- Date of joining: June 8, 2016 Messages:15,873Likes Received:11,262 I had intended to use a smaller vegetable area, but I ended up utilizing the same size vegetable area, which I really like. It provides you with the option to train the plant canopy to fill the same amount of area before you relocate it to another location. You also have plenty of area in the corners for little plants that will be used for the following crop. The veg tent ends up being used for seedlings/clones as well as vegetable plants in the end. I believe you would be content with a 4×4. While I purchased a 4×8 and divided it in half, I believe you would be better off with two separate 4x4s. Four QB96s and two HLG-320h-54 A drivers for flower are my favorite initial setups on a 4×4 truck. QB120V2s in 4K for veg or whatever else you can get in 4K, such as 132 V1s, will suffice. There are four of these. QB96 Elite V2 Engine, one of a four-pack of these engines. Quantum Boards QB132 V1 (Quantum Board 132 V1) There are two of them for the bloom. One of these for the vegetables. Connect the flower lights in a parallel fashion to two boards on either side. The veg boards will be connected to the driver in a sequence of four boards.

- I want to purchase all of the items you recommended. Specifically, do they come with wiring or do I have to purchase it separately? Also, what is the most effective method of ventilating the two tents? Is it possible to connect them together and utilize a single exhaust fan to exit the house?

- Date of joining: March 2, 2013 Messages:4,047Likes 86263 pieces were received, which is sufficient for a 5×5 space. The overall draw power must be at least 750 watts, and as previously said, it has the potential to save more than 30% on energy costs. In conventional LED grow lights, plants require 30-50 watts per square foot of growing space, but under the SP-250, they may thrive with just 21-35 watts per square foot of growing space.

The excellent power handling capability of those boards, which would be severely constrained if not for the high-quality heatsink and thermal interface pads that come with them, is one of their most appealing features. I’ve simply been looking into where I might be able to find such kinds of products in some alternative types of stores. There is nothing perfect yet. Rapid leds have heatsinks that are spherical in shape. I’m not sure if these would be effective. Pin Heatsink with a 140mm diameter. Thermal interface pads are used in a variety of applications.
Best LED Grow Lights 2021
LED grow lights for big areas may be rather expensive, especially if they are custom made. Growing lights on the market today are either inefficient or do not adequately cover the specified coverage area. In addition, many of these lights are significantly expensive.

Choose the Right LED Grow Light Based on Your Grow Tent Size ?
For the first time, you’re learning how to put up a grow tent. Making the conversion from high-intensity discharge to LED grow lights? In either case, it’s critical to select the appropriate LED grow light for your tent size. LED lights provide a significant benefit for both you and your plants when you choose to utilize them. In fact, LEDs are the only lights that are capable of supplying plants with the precise light spectrum they require during the whole growth cycle. These lights, in addition to providing the finest quality of illumination, consume the least amount of energy to operate properly.
The full benefits of LED grow lights, on the other hand, are not available if the fixture you pick is not appropriate for your grow tent.
Step 1: Establish Whether Your Grow Tent is for Veg, Flowering, or Full Cycle Growing
Do you have a vision for how you want your grow operation to be set up? Do you intend to move plants between a specialized veg tent and a blooming tent during the growing season? Alternatively, do you want to keep your crop in the same enclosure during its whole harvest cycle? This is an essential question for a few of reasons. First and foremost, the response informs you of the sort of LED light you require. If your plants will be growing in this tent for the rest of their life, you may wish to invest in a variable spectrumLED that lets you to modify the light spectrum between each phase of growth and development.
Second, plants in the vegetative phase require approximately half the amount of light intensity that they require during the blooming phase.
Step 2: Decide How Many Plants You Plan to Grow In Grow Tent
It is not only about the size of the tent that you should consider when selecting the appropriate lighting for your grow tent. It’s also about the size of the canopy and how well it occupies the available area. Plan on providing at least one square foot of space for each plant if you aren’t sure how many you will be cultivating. Allow adequate room for your crops to spread out and become wide and bushy. When the plant begins to blossom, you will be in a great position to harvest large quantities of fruit.
Every LED grow light should include easy-to-find specifications on its product page, just like any other electronic device.
Step 3: Estimate How Much Wattage You Need for Your Square Footage
We’ve included this step since it’s one of many considerations to examine, but it’s not a hard-and-fast rule, and it should be treated as such. We’ll start by sharing a common rule of thumb, and then we’ll explain why you should use caution while using it. According to conventional wisdom, you should aim for 32-50 watts per square foot of growing space. If your grow place is a specialized veg tent, you’ll need something closer to 25 watts. Using this example, if you’re dealing with an area of three by three feet, you’d potentially require an LED light with a power demand of somewhere in the range of 225 watts (vegetative) and 450 watts (hi-intensity) (flowering).
The difficulty is that watts don’t tell you anything about the quality or intensity of light produced by a fixture, only its quantity.
Top-tier LED lights are incredibly energy-efficient and can generate an equal spread of high-intensity light while using only a little amount of electricity.
This lamp, on the other hand, has a PPFD rating of 800 and covers a coverage area of 3′ x 3′. And if none of it makes sense to you, don’t be concerned about it. We’ll go over it in more detail in Step 4.
Step 4: Compare PPFD Levels of LED Grow Lights
You may obtain more in-depth information about PPFD measurements by visiting this page. In the meanwhile, we’ll try to make things as simple as possible. The photosynthetically active radiation (PAR) transmission factor (PPFD) informs you how much photosynthetically active radiation (PAR) really reaches the canopy from a certain hanging distance. Here, we’re talking about the amount of useable light that makes its way from the bulb to the foliage. Follow these steps to grow plants that are healthy and flavorful:
- Seedings and clones require 200-400 PPFD
- Vegetation requires 400-600 PPFD
- Budding and blooming require 600-900 PPFD
- And fruiting requires 900-1000 PPFD.
Understandably, it is necessary to select whether you want to commit your grow tent to a certain stage or to the complete cycle before you begin. When reviewing the characteristics of an LED grow light, be certain that the light can deliver the following benefits:
- The PPFD level required by your plants
- It should have a broad enough covering area to guarantee that the entire canopy receives sufficient quality light.
It is also crucial to note that the PPFD of your lights is dependent on the height at which they are suspended. The quality of the light declines as one moves further away from the bulb. It is possible to measure the quantity of PAR that is available at a certain distance from the fixture using a PPFD measurement. When you look at the PPFD specifications, make a note of the distance at which the measurement was obtained. For example, the 200-watt SolarXtreme 250 has a 500 PPFD at 18″ and weighs only 18 pounds.
- When deciding on the best LED grow light for your tent size, remember to take into account more than simply square footage when making your decision.
- Don’t be fooled by low-cost lighting options.
- To note the fact that having some assistance while erecting a tent for the first time is quite beneficial.
- Please let us know if there is anything we at California Lightworks can do to assist you in getting started.
LED solution recommendation to suit 5×5 grow tent
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. Greetings, 420 magazine To get the most out of my plants that will be housed inside my 5×5 grow tent, I’m stumped on how many LEDs I should put inside the grow tent. Any suggestions? Growing is something I’m familiar with, but with the advent of LED lighting technology, I decided to give it a shot. There’s still a lot I’m learning, and I’ve reached a brick wall.
- I now have two viparspectra V600 leds that I purchased, but I believe I will require more to get the yield that I have specified above.
- My concern, which I’m hoping some growers would be nice enough to answer, is if 4 V600w viparspectra LEDs will be sufficient to achieve the yield targets I’ve set for myself, or whether I’ll need to invest in something more powerful.
- For the time being, however, I require the most appropriate lighting option to achieve my production objectives.
- With LEDs, if you’re aiming for optimal yield (as opposed to the bare minimum required), you should be looking for 50 Watts from the wall per square foot of your growing space for the purple LEDs.
- The maximum yield with blurple LED in a 5×5 will come from somewhere between 1000 and 1200 watts from the wall.
In fact, 4 of your 276w units would put you at 1104w from the wall, which would be perfect! Thank you so much, fanleaf, for your response. It appears that I was on the correct track at the time.
Best/energy efficient LED setup for a 5×5 grow tent
Since I’ve been singled out. So far, I’ve been quite pleased with the sp250s. I’ve had them for approximately six months at this point. Despite the fact that I use two xsp250 in a 5×5 tent, my canopy measures around 2.5′ x 4′. If I were to utilize the full tent, I’d need three or four sp250s, at the very least. It may be necessary to take this into consideration when evaluating pricing depending on your watts per square foot requirements. Because my tent is eight feet high, dimming is not an issue for me.
- This website has the PAR charts that you were looking for.
- I had intended to install the two bars together in a grid arrangement, with room for a third bar in the future, similar to the other two brands, but I changed my mind.
- Because I grow various strains together, I appreciate the ability to individually change the lights to accommodate an uneven canopy, which gives me more freedom.
- I hope this has been of assistance.
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.
Scroll down to the bottom of the page to identify the sort of lighting you intend to utilize. 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.
- 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).
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).

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.
That doesn’t rule out the possibility of figuring it out. In this case, there are three options to examine. I’ll list them in descending order of difficulty, starting with the easiest (and least accurate) and progressing to the most challenging (but also the most accurate).
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.

It can be used to grow a variety of plants in the vegetation stage and in the blooming stage. The advantages and disadvantages of this particular lighting system will be discussed in this evaluation.
Warm white light (3000K) is used to preserve and retain the color of the plants. In order to enhance plant development, use blue light (5000K). In order to encourage your plants to flower healthily, use RED light (660 nm). In order to assist your plants bloom and prosper, use IR light (760 nm).
2. Aluminum Hood to Optimize Heat Distribution and Light Reflection
The design of the aluminum hood serves a number of purposes. First and foremost, it contributes to the prevention of overheating of the grow light itself (though it will still be warm to the touch) by spreading the heat across the other layers of the lighting system. For the second reason, the layering and design themselves assist in concentrating and utilizing light so that it is not squandered, hence increasing usage for the plants themselves.
3. Easy to Set Up and Hang
In addition to the two hangers that come with the grow light, you can purchase an extra set for a low cost of $7.99. However, the grow light is also pretty adjustable, and it can be hung up just as simply with paracord or other hangers if that is your preferred method of hanging it.
In the end, it shouldn’t make that much of a difference to the outcome.

With LED lights for your grow tent, there are already a lot of considerations: how big do you want it to be? What kind of lighting do you want? Should I purchase one that includes a fan? In order for my plants to thrive, what sorts of lighting are required? And, finally, how many LED watts are suitable for the plants that I am now growing? The answer to that final question will be heavily influenced by a number of factors, the most important of which are as follows: What kinds of plants do you have in your garden?
This post will cover the essentials for a 5′ by 5′ grow tent and everything you’ll need to put up.
Flowering plants such as tomatoes, peppers, and even root crops are classified as High Light plants, which means that they require a large amount of additional sunshine (or sun-mimicking light) in order to survive and produce flowers. Unlike Low Light plants, these plants will require a greater wattage since they require significantly more energy than plants that remain in a green or non-flowering condition, and this energy is stored in the fruits of the plant. For a 5′ x 5′ area, high-light plants in the blooming stage can demand as much as 1800 watts of light during the flowering period.
Low Light Plants (i.e. Leafy Greens)
As a result of the fact that they will not develop fruit, leafy greens including spinach, lettuce, kale, and chard are classified Low Light plants. As a result, they use substantially less light energy than plants that do yield fruit. A grow tent of 5′ x 5′ should be used to treat low-light plants, which should get a maximum of 450 watts of light per square foot.
General Rule of Thumb
However, the aspect that will make the most difference in how much LED wattage you require is whether or not you are growing High Light or Low Light plants. There are a variety of other considerations to bear in mind as well. Other than that, the basic rule of thumb to follow when determining how many LED watts you require for your grow room is as follows: Low Light plants require around 50 watts per square foot of grow space (i.e. 1′ x 1′ = 50 watts, 2′ x 2′ = 200 watts, 5′ x 5′ = 1250 watts, and so on) to thrive.
If you require more information or have plants that are particularly specialized to your environment, we recommend that you conduct more study on your specific conditions.
