LED grow light reviews

When you realize that your plants aren’t getting all the natural light they need, considering the various grow light options that are out there is a good first step. From there, it probably won’t take long until you find out about the existence of LED grow lights, as there’s a reason they’re the most popular type of grow light. But surely they’re the same as the LED lights you already have at home, just more expensive?

After all, what is the difference between LED lights and LED grow lights? Can’t any LED light be used as a grow light?

Well, not quite. When your goal is to ensure your houseplants grow thicker or start to bloom, it’s important to be aware of not only the different types of grow lights out there, but how they differ to their more standard variations. And as you’ll see, while it’s true that an LED grow light may cost slightly more than a regular light bulb, the benefits more than make it worthwhile.

Advantages of LED Grow Lights

In the early days, technology was impractical and cost-inefficient. But in recent times, the newest technology has increased production, due to which it has become cost-effective. These are energy-efficient plant growth lamps and come with a shorter life span. However, as a result, it makes them costlier in the long run. Sometimes, the heat emitted by HPS lamps is lucrative in greenhouse settings, but these can make them useless for vertical farms or growth chambers.

On the other hand, these are more compact and faster switching, making them ideal for the environment. Moreover, these release less incandescent heat, affecting plants’ moisture and nutrition requirements. Compared to the conventional HPS models, the benefits of the revolutionary models are as follows:

Economic Electricity Consumption:
The LED grow lights for indoor plants use up 50% of the energy used by HPS systems. According to a few experts, they anticipate higher LEDs efficiency shortly.

More Extended Lifespan/Lamp Durability:
They are more long-lasting than the HPS ones. When it comes to HPS lamps, the lifespan is usually one year, whereas, for LEDs, the lifespan is up to 8 years or about 50 000 hours of use.

Smaller Spaces Convenience:
You can set them closer to the plants. However, the growing space should not be extremely high or wide.

Energy Efficiency:
Using them, you can optimize the spectrum while concentrating energy on the wavelengths. These are lucrative for every application and plant. Moreover, the decreased heat production lets you put LED fixtures near plants, ensuring that you have lost less light elsewhere.

Fire Safety:
You can use them safely as these don’t become warm as the conventional HPS lamps.

Dimming:
Mostly, HPS lamps use the full light intensity, whereas these dim. It is possible with a remote control or via an app. As a result, you can handle it easily apart from consuming less power.

Better Crops:
LED grow lights for seedlings can generate better crops to get bigger plants and allow them to grow fast than the HPS ones. In addition, these consist of a spectrum aimed at a specific goal, including anthocyanin accumulation, flowering inhibition, enhanced rooting, etc.

More Environment Safety:
These emit less heat. Besides, you can add UV light to these lamps, reducing bacteria and mold formation probability. It indicates that you will have fewer pesticides and less environmental pollution.

How to Choose the Best Full-Spectrum Grow Lights?

Purchasing grow lights is not always a walk in the park. If you want more information on growth light specifications, you’ve come to the right place. The following buying guide covers everything you need to know before you set out to find grow lights for your operation.

Light Strength
Before you can begin shopping, you will need to know your target growth light intensity.

Consider the Light’s PPF Rating
The PPF, or photosynthetic photon flux, is the number of light photons that are produced by a light fixture each second. PPF is measured using a PAR, or photosynthetic active radiation, meter. The measurement is then expressed in umols per square meter per second. An ideal PPF rating ranges from 400 to 700 nanometers.

Check the PAR Findings
PAR, or photosynthetic active radiation, is the wavelength of light within the visible range. This figure starts at 400 nanometers and ends at 700 nanometers. Your target PAR depends on the type of plants you are growing as well as the distance of your lights from your plants.

Common vegetables, including tomatoes and lettuce, require 400 to 500 umols/m2/sec. Meanwhile, the recommended PAR level for indoor plants is 300 to 400 umols/m2/sec.

Few plants require more than 1,000 µmols/m2/sec of PAR. In most cases, a light that offers 500 to 1,000 umols should be sufficient. You can usually get away with lower PAR ranges during early growth stages. Meanwhile, more powerful PAR ranges are needed during flower and fruiting.

Analyze the PPFD
PPFD, or photosynthetic photon flux, is a unit of measurement used to describe light intensity in a specific area. Or, in other words, it is the amount of light that falls on the PAR region of your growing area every second. As we already know, plants need 500 to 1,000 umols of PAR per square foot per second.

PPFD is sometimes confused with PPF. However, PPFD is the amount of light that actually impacts plants. Whereas, PPF is the amount of light produced by a fixture.

Spectrum
Light spectrum is yet another key factor concept that you need to understand before you select the right grow light. A qualifying light needs to offer a full spectrum of light colors to promote photosynthesis (chlorophyll absorption). Most growing experts recommend a full-spectrum fixture that offers a ratio of blue and red light as well as some UB and far-right radiation (photomorphogenesis. This spectrum usually covers the full photosynthetically active radiation range (PAR) or 400 to 700 nanometers.

Virtually every stage of the plant life cycle is dependent on targeted light wavelengths. This includes fruiting potential, flowering yield, vegetation growth, root growth, harvest characteristics, and harvest yield.

Blue light, which also falls within the 100 to 400-nanometer range, can determine the vegetation development, root development, and flower development of plants grown indoors. Meanwhile, red light (600 to 700 nanometers) improves plants’ photosynthesis and biomass. The UV wavelength, which ranges from 100 to 400 nanometers, is responsible for flavor and photosynthesis.

Most plants come with a recommended blue to red ratio. For example, lettuce fairs best with a 35:65 blue to red ratio. Meanwhile, tomatoes turn out best when they are exposed to a 5:1 ratio of red and blue.

Some growers think of light spectrum ratios as an element of plant design. When you understand the impact of light spectrum ratios on your plants, you can easily make changes to determine the outcome of your harvests.

Wattage
One of a grow light’s most important performance specs happens to be power consumption. This is the amount of wattage that your fixture draws from the outlet. The diodes that are built into LED lights are capable of producing intense light with small amounts of electricity.

Of course, wattage is also used to measure the amount of power that a fixture produces. Oftentimes, a manufacturer’s reported light output is higher than its reported wattage draw. When it comes to LEDs, there is often an exaggerated difference between these numbers. For example, the KingLED Reflector Series LED Grow Light mentioned above is described as having a 3,000-watt output and a 615-watt draw.

While you might be eager to save a buck on your electricity bill, LED lights with low electricity consumption are not always as promising as they appear. Oftentimes the lower power equates to lower production. If your fixture isn’t capable of producing enough PPFD, then it’s not going to help grow plants efficiently.

Most growers like to have a good idea of how many watts of electricity they’re using per square foot of grow space. This helps them to calculate their overall electricity expenditure. A draw of 20 to 50 watts per square foot is standard. You can use this calculator to determine how many watts of power your lights will use per square foot.

Understand Driver/Chip Compatibility
LED grow lights consist of corresponding chips and light-emitting diodes (LEDs). The chips transmit messages, such as light settings and timer settings. When these elements synchronously, growers can alter their lights’ PAR spectrum to better suit each plant growth stage.

Coverage
Another essential consideration is growing space coverage. You need to be able to calculate the amount of growing space that your fixture can support. This number varies from grower to grower. After all, some people are managing large warehouses, while others boast 4-by-4 grow tents.

Generally speaking, lights with higher wattages are capable of covering larger areas. You will need to consider a light’s wattage, coverage area, and distance from plants before you can determine how many lights you need for your growing space.

Take into account that you may need to raise or lower your lights during different growing spaces. Raising and lowering plants alters a light’s overall PAR per square foot.

Cooling
While LED grows lights do not get nearly as hot as traditional light fixtures, they still produce excess heat. Most lights have a combination of onboard heat sinks, radiators, and fans that help them to maintain a reasonable temperature.

Without a reliable grow system, you risk exposing your plants to excess heat and dryness. The heat that is produced by LEDs has nowhere to go inside a grow room or tent. As such, it is automatically absorbed by the plants and other objects in a growing area. Grow rooms should be well ventilated. The temperature inside the room should fall somewhere between 70 and 85 degrees Fahrenheit when the lights are on.

You can calculate a grow light’s estimated heat production by multiplying the number of watts used by 3.41. This gives you the fixture’s heat production in BTUs (British thermal units.) You can also check out this online calculator to determine the total BTUs of cooling needed for an LED light.

Controls
Lights with built-in or remote controls give you the freedom of programming. You may be able to set a timer, adjust the red, blue ratio of your light, or alter a light’s intensity to better suit your growing needs at any given time.

Included Accessories
If you’re setting up a grow room for the first time, you’re going to need a good amount of accessories to complete your installation. Consider it a bonus if a manufacturer includes ratchets, hooks, and/or other hardware with their grow lights.

Warranty
Most LEDs have promising lifespans, with many ranging between 20,000 and 100,000 hours of estimated runtime. While most LEDs live up to their promises, we still like to see companies stand behind their claims. Three-year warranties are commonplace for LED grow lights. A lengthy protection plan guarantees that you are covered even in the rare chance something goes from with your fixture.

Price
The cost of LED lights is yet another essential consideration. Most fixtures average in the hundreds, but professional models can cost much as $2,000 per unit. When you purchase an LED light, you’re making an upfront investment. You’ll reap the benefits of your investment so long as the fixture’s lifespan and light intensity live up to the manufacturer’s promise. Hopefully, you’ll opt for a model that also boasts a lengthy and worry-free warranty.

If you’re shopping with a limited budget, you’ll want to pay careful attention to the light intensity, spectrum, and coverage offered by your chosen light. The right light should present energy savings alongside healthy plant growth.

Conclusion

After reviewing all the best LED grow lights for indoor plants, we cannot declare a clear winner because every grow light has its distinctive features. Now it all boils down to your personal preference. If you’re running low on budget you can choose a budget-friendly option otherwise you can go for a premium model. Look for a light system that is best for a range of different plants and boasts blue and red spectrum. You also need to go for an adjustable timer ranging.

Grow lights are perhaps the most important part of any indoor grower’s setup, especially when it comes to growing plants. They may also play a role in outdoor growth, but when it comes to growing plants indoors, you just can’t ignore their importance. Grow lights are essentially replacing the sun — which is a big deal. Over the course of this article, we shall be taking a closer look at the best LED grow lights.

There are many different kinds of grow lights out there — HPS lights, Metal Halides, fluorescent lighting, etc. However, when it comes to getting something that lasts for really long, saves you a lot of electricity expenses, and operates at cool temperatures — there’s practically nothing that beats LED grow lights. These lights range from $50 to $2000 or more.

However, most growers prefer not to spend too much on grow lights, especially if they are just starting off with their growth or want to grow in a small area. There are some people who are also looking for backup grow lights or temporary lighting solutions and might not want to spend too much on them. Hence, these grow lights are actually very well suited for their needs.

As you go through this article, you will see that there are actually some very good quality grow lights in this price point — and from some of the leading brands too! Let us take a detailed look at the best options:

How to Use Your LED Grow Light for Plants

You want your indoor plant to get the most out of growing light when you use it because this gives you the best chance of having a successful indoor crop all year round. If you have an HID light, you want to keep it at least 12 inches away, fluorescent lights should be as close as possible without burning them up to 12 inches, and an LED grow light can be six inches or more from your plant.

You typically put your grow light above your plants to encourage photosynthesis. As they start to sprout and grow, you’ll raise your light. Keep your light at the optimal distance depending on the style, strength, and whatever you want to grow.

Your plants need as close to the full light spectrum as possible because this mimics natural sunlight. You measure the different colors of the light spectrum by the temperatures they emit. High-quality LED grow lights and products emit more than one color, and they can cost more to do so.

Understanding what light spectrum your plants need will allow you to tailor your light choice to encourage the maximum growth throughout the year.

If you’re not sure what color your plants need to thrive, take a look at their specific needs. Tomatoes and other producing plants have more than one growth phase they cycle through. During the first stage, they leaf out and turn into more than a single plant. During this stage, they need more blue spectrum lighting because it’s warmer.

The second phase of the plant growth cycle starts when they begin to sprout flowers and reproduce. In order to help your plant reach this phase and cycle through it, your plant will need cooler temperatures like the yellow and red growth lights give. You want red lights for the growth stage as well

Conclusion

These LED grow lights are the perfect choice for any indoor grower looking to upgrade their indoor plant lighting. Grow lights are not only lightweight and easy to set up, but they also operate quietly. They are exceptionally bright and will flood your tent with effective PAR values for superior plant growth and higher yields.

Best LED Grow Lights Buying Guide

Before buying the suitable LED grow light for your indoor garden, you must consider the following factors to get the ideal one:

1. Spectrum Type:
As we have mentioned above, different wavelengths of lights are responsible for the various growth stages of the plant. Depending upon the type of harvest you want to cultivate in your indoor garden, you should opt for specific grow light with a suitable wavelength.

Suppose you have multiple plants at different growth stages. In that case, it is advisable to go for an adjustable LED grow light that can tune to different wavelengths depending upon the plant requirement. So, always check the light spectrum and its wavelength range before buying the one for your plants.

2. Heat Output:
It is a crucial factor to consider while buying the top LED grow light for your indoor garden. Grow lights are generally mounted close to the plants, and thus, these LEDs mustn’t produce overheat as they can damage the plant’s growth.

LED with heat sinks or cooling fans are suitable for vertical gardens or indoor plants as they have no adverse effects on plants and can be placed even closer to them. An ideal Grow light must produce low heat to be the last longer, and you don’t have to replace it soon.

3. Grow Space Size vs. Light Coverage Area:
Depending upon the grow space size, you decide how many lights of how many watts will be sufficient enough for various plants’ growth. First, you should determine the size of the garden and then consider the area each light needs to illuminate.

Different plants require different voltage for their proper growth. For example, if you want to grow tomatoes, 32 watts of LED light per square foot will be suitable for it. But if you’re going to produce light harvests like Lettuce or anything, 11–18 watt per square foot is sufficient for that.

4. Efficiency:
The efficiency of the Grow Lights is one of the critical aspects you must check. An ideal grow light must be operated at a high level to produce high energy with a low maintenance cost.

So, before jumping to the suggestions of the best LED grow lights, you must consider all these aspects, make your calculation and then choose which one is ideal for you according to your requirements.

5. Real Wattage vs. Theoretical Wattage
Most of the LED lights have two wattages: Real Wattage and Theoretical Wattage displayed on their packaging. Theoretical Wattage is the potential wattage on which an LED light could run when LED chips run at full power. For example, A 1000W LED light can have theoretical wattage of around 600Watt. But LED lights never run on full power as it will shorten their life.

So, LED lights always run at 50–60% of their theoretical wattage, known as their real wattage. It is the amount of light LEDs actually consume to perform. So, a 1000W LED light generally has real wattage of around 300–400 Watt, and you must consider both these wattages before buying a grow light.

6. Cooling System
Large LED lights emit more heat while providing intense light to your plants for their growth, and thus they must be equipped with a proper heat sinking system and cooling fans for heat dissipation.

In the absence of both these things, the life span of LED light will shorten, and performance will decline. Also, the overheating won’t be good for your plants as well. So always give attention to the cooling system of LED grow light before buying one.

Why is the flowering coverage important while choosing a grow light?

When you are looking for a grow light, the only coverage number you need to consider is the flowering coverage. This is because vegetative coverage is usually larger than flowering because the height of the light is a little higher at that time. Basically, if you’re growing in a 4×4 area, and if your vegetative coverage is 4×4, then the flowering coverage is going to be 3×3 and some of your plants will be left out. This happens because the light is generally lowered and brought closer to the plants during the flowering phase. Hence, always make sure you’re buying the grow lights based on the flowering coverage and not the other number.

Conclusion

When it comes to LED grow lights, there are just way too many options in markets out there. With 4×4 grow tents being among the most popular size of grow tents, we thought it was important to put out a best-of list out there. We have tried to provide a review that is as detailed as possible, along with all the pros and cons of the products. However, if you think there’s a specific aspect that you want to know more about, or want us to review a grow light of your choice, do reach out to us over comments or on mail and we shall get it done as soon as we possibly can!

When it comes to growing a productive indoor crop — the grow light of your choice will play a significant role. From lush, green foliar growth, rapid rooting, and a bountiful yield — grow lights play a key role during the entire indoor cultivation process.

What Type of Lighting Do Plants Need?

The first rule of indoor plant cultivation is that not all lighting is created equal. This means that, in the world of plants, they do prefer a specific range of light.

This range is known as photosynthetic active radiation (PAR) and describes wavelengths of light between 400–700 nanometers. For humans, the majority of light looks the same; however, plants experience PAR lighting in a very different way.

When exposed to usable light, such as the light in between 400–700nm, plants undergo photosynthesis, phototropism, and photoperiodism. These three functions are the reason why plants can grow leaves, turn towards the light, and eventually flower.

Therefore, when choosing the right grow light for your indoor grow — you’ll need to find a grow light with an optimized PAR range that caters to your plant’s needs. Let’s take a look at the two dominant color spectrums of light that are commonly used for growing plants indoors.

The White and Blue Spectrum of Light
As the spring comes to a close and summer begins, the sun reaches its apex in the sky. Not only are summer days long, but the light produced by the sun is also incredibly bright. When measured, this light falls under the white and blue spectrum of the PAR range.

Research shows that the bright light associated with the 400–470nm range (bluish-white) promotes strong vegetative growth and increased rooting. It’s for this reason that many indoor cultivators choose to use grow lights that produce light within the 400–470nm range while vegetating their indoor crop.

The Red and Orange Spectrum of Light
As the summer months wane and autumn sets in, the sun no longer reaches its apex in the sky. Instead, the sun begins to skirt across the horizon as the days become shorter — and colder.

The light that’s associated with the angle of the sun during this transition to shorter days is 620–700nm (orange-red). Research indicates that the red-orange color spectrum is a prime influencer for plants to begin the flowering process.

In regards to indoor plants, cultivators use this natural mechanism to their advantage. By harnessing photoperiodism, indoor growers use grow lights that produce light in the 620–700nm range to promote robust flowering.

That’s why the plant light you choose should be as flexible as possible so you can use it easily, even if you decide to change the place of your plants. Choose either those with the expandable design or LED strips that have gooseneck since those will be the easiest to adjust.

Installation
As you probably noticed in previous reviews, the majority of these models provide you with all the required parts for the installation.

This is very helpful since you’ll be able to install and use the strip grow lights as soon as they arrive. What’s also interesting to notice is that the smartest option when picking your grow lights is to buy those that can be installed in more than just one way.

Why is that important? Because in that way, you’ll be able to place the lights on various surfaces and change the place of installation multiple times if necessary.

No matter on which surface you need to install the lights, you’ll do it in quickly and effortlessly if you buy LED strips that come with double-sided adhesive tape, zip ties, and mounting screws, maybe even magnets — everything you need for an effortless installation.

Pick the right dimming levels
This is an important aspect for both regular and strip grow lights. The most desirable model will be the one that enables you to choose the brightness intensity and adjust it to your plants’ requirements during plant growth.

Many models offer five dimming modes that will make a perfect purchase for various kinds of plants as well as stages of germination. You’ll get to use the strip lights on multiple occasions and not solely for one plant.

Weight & support
Since full spectrum grow light strips are meant to be practical and useful, they should be light in order to be properly installed. You surely don’t want the danger of having the lights drop on your plants — choose the model that’s lightweight and be worry-free.

Timer is a great feature
If you’re away from home often, you’ll appreciate the practicality of having a full spectrum LED strip grow light that has the timer function included.

That will give you peace of mind when you’re not home because you’ll know that the timer will switch the grow light on and off automatically, depending on how you pre-set it.

Consider color spectrum
It’s always the best decision to choose strip grow lights that produce both blue and red light for your plants’ germination. Do your research and choose the best combo of red and blue light according to your plants’ requirements.

If you have more plants that demand different blue-red light ratio, buy full spectrum plant light that enables you to turn both colors on and off individually and create the combo you need. This way, you can provide both blue and red light.

Conclusion

LED Grow lights have come a long way in the last 5 years and there are some great new designs and changes that make these lights even more attractive to home gardeners. In this review, I believe that you have a look at some very important innovations and price changes of LED grow lights that make LED grow lights an even better choice. I wish this article will help you. Happy growing!

Many peoples want to know about “what size led light for 2×4 grow tent”. If you have the same question so you are on the right way. We will tell you about it soon. But first, let’s say something about light for growing plants in general.

What Size Quantum Board Led Grow Light For 2×4 Grow Tent?

The size of the Led grow light depends upon the size of your grow tent. Also, the height of your plants and the number of reflective materials in the setup also matter. For example, with 6 plants in a grow tent, I would recommend a 400w Led light with a 50x50x6 inch reflective hood. 400w Led light can cover 6x2x4 feet grow tent. So the 2×4 grow tent is the minimum size grow tent that can be covered by 400w Led grow light.

How many plants grow in a 2×4 tent?

There are two ways to counter this. In the first calculation, we will use the standard industry definition “plant”. A plant is any mature vegetative organism that can be cloned from a single parent. Thus we need to figure out how many of these grow in a 2×4 tent. A 2×4 tent is a standard size for a small indoor grow operation. The term “2×4” refers to the size of the tent. 2 feet by 4 feet.

The width is 2 feet and the length is 4 feet. A “2×4” tent is a 1x3x3 grow tent. A 1x3x3 is a regular octagon shape. There are 8 sides so you can grow 8 plants in it. The second way of figuring this is to just consider it a standard 1x3x3 grow tent. In that case, you can grow 1 plant in it.

How much can you yield in a 2×4 tent?

If you plant your plants in pots and stake them up, you can yield 1.5 ounces per plant. If you plant them directly in the ground, you can yield 1.2 pounds per plant. The difference is that by planting the plants in pots, you have to harvest the buds and remove all the branches. But this method allows you to pick individual buds without damaging the plant. When you plant them directly on the ground, you can remove the whole plant and hang it upside down to dry.

Buyers Guide

As more States have moved towards the legalization of plants led to increased indoor growing of plants. And in a bid to maximize yields, growers of plants have resorted to using kits as they consume less electricity, produce minimal heat and produce high plants yields.

In this regard, modern kits are years ahead of their predecessors that were rarely used in the indoor growing of plants. When buying led grow lights for your plants growing needs, there are a number of things you need to consider. Below are the main factors to consider in your search for the best LED grow lights for plants.

Price
As with any other appliance, price is an important factor to consider when choosing a panel for growing plants. However, it should never be the main factor that influences your decisions when selecting led grow light kits. The main reason why LED lights are in so much demand is they save on electricity costs and bulb replacement costs.

Contrastingly, if you have more plants to grow a $1000 led grow light will do a better job. A cheaper light will be incapable of providing light efficiently. To get a balance between price and performance go for a mid-range led grow light. These are lights that cost between $200 and $500. These lights offer more power compared to $100 grow lights but are less expensive than $1000 kits.

Warranty
Similar to any other product, the best led grow lights come with warranties. Some manufacturers offer a warranty of up to 3 years while others offer a limited warranty of 1 year.

When purchasing a led grow light be sure to check the warranty vis-a-vis what you are paying for it.

Construction
In every market, there are bound to be cheap knock offs and the led grow light market is no exception. Ordinarily, they are made using metallic components; however, there are a few cheap knockoffs that are constructed using plastic. Plastic is less durable compared to metal and thus plastic lights will have a shorter lifespan.

The most common metal used in the manufacture of best led grow lights are aluminum. The latter metallic material is a good conductor of heat and thus helps transfer any excess heat produced by the panel. This helps you minimize the amount of water you use on your plants.

The biggest problem with conventional HPS bulbs is that they emit up to 80% of their energy in form of heat. Therefore, when you are using these bulbs you will have to water your plants regularly. LEDs, on the other hand, convert a meager 15% of their energy to heat. Thus, the aluminum housing goes a long way in reducing the amount of heat produced by the light emitting diodes. If you stumble on a plastic panel do not buy it regardless of how cheap it is as it will be expensive in the long run.

One of the most important components of the best led grow lights are the drivers. There are two types of driver systems constant current and constant voltage. To ensure that your grow light is long lasting go with one that has the constant current driver.

The benefit of this driver system over the constant voltage system is that constant current keeps the current of the LED steady as temperature increases. The voltage tends to drop as temperatures increase. To counter this problem, it is wise to go for a constant current driver that maintains the LED’s steady voltage at all times.

Adjustable Spectrum
A full spectrum light will be ideal for all stages of a plant’s growth. Many of the mid to high-end panels reviewed have the ability to switch between vegetative and flowering stages with a flip of the switch.

This has two benefits, one being able to use less energy during the vegetative stage as plants doesn’t need as much light during this phase of growth. Second you will have the correct spectrum of light during the flowering stage to grow huge buds. Ideally, do some research into the different full spectrum led grow light brands available and choose the one you prefer.

Conclusion

There is no doubt that great satisfaction can be achieved by growing your own plants. For some people, indoor gardening is a fulfilling hobby, but for others, it is a serious enterprise that can significantly add to their income. No matter what is your motivation, there is a LED grow light setup that is perfect for your situation and budget.

By acquiring the best LED grow light for 4×4 grow tents, any crop will be much more efficient and productive. To this end, we analyzed the best tools for all the people interested.

This means that growing plants and flowers is now much easier. Even a grow light allows for great versatility in the location of a crop. Many plants and flowers will be able to be grown indoors in a home or commercial store.

What size LED light does a 4×4 cultivation require?

On the one hand, heat dissipation is one of the fundamental aspects depending on the number of plants or flowers in a given crop. Here it is necessary to take this aspect into account since an excessive amount of lighting could damage the plants considerably.

In turn, a grow cabinet with dimensions of 4 x 4 can offer between 500 and 1200 watts. Here it is also important to consider the type of plants or flowers. Different flowers and vegetables have varying requirements.

So the requirements of the different plants and flowers in a crop vary. This can certainly be very decisive when choosing the best LED light for 4×4 grow tent. Also, the most important thing is to avoid too little or too much lighting for the correct growth of the crop.

How to select the right LED for cultivating light?

Some factors are important in choosing the grow light that the plants need. In this case, it is a matter of taking into account the type of plants and flowers that are needed in a given crop. Some plants may need moderate lighting, while some flowers need a lot of light.

In particular, these aspects are critical because too much light can burn some plants, and too little light diminishes flower growth. So the spectrum and the amount of light produced by a grow lamp are critical aspects to consider.

Even the spectrum is the ability of a grow light to cover all stages of flowers and plants. Also, there are other basic aspects to consider, such as the installation procedure, a waterproof structure, and heat dissipation.

Although all these aspects are secondary, they are also important enough to develop cultivation with a good level of comfort. If energy efficiency is added to the above aspects, the user will be able to choose the best LED to grow light.

Features and Benefits of LED Grow Lights

From professional gardeners to beginners, you can get huge benefits from grow lights.

You can use grow lights at all stages of your plantation (seeding, vegetables, flowers and fruits). Therefore, gardeners can use it for single or multiple purposes in the plantation.

If you see yellowish leaves and long branches, there may be a lack of light. You can use individual grow lights on that pot or throughout the garden.

In winter, grow lights can help keep your entire garden alive.

Grow lights allow you to start a garden in remote areas where sunlight is very scarce. You can even use these lights to grow a plant in your basement.

It helps keep plants healthy and free from disease. All fertilizers, water, and temperature are also important to having a disease-free garden.

Grow lights can increase the production of flowers, fruits and seeds in your garden. So, every time you harvest, you will reap the biggest harvest.

Grow lights or led grow lights are flexible in design and technology. You can use them as multi-level vertical systems, ceiling lights or lighting designs between plants. This type of lighting system is used in greenhouses and large indoor gardening. LED lights are best suited for this typical lighting system.

Another benefit of LED lights is that they produce less heat and provide better lighting performance. LED grow lights emit less heat than other lighting methods. Too much heat can damage plants, reducing growth and possibly causing plant death. LED lamps are more efficient in terms of low heat generation and bright lighting.

Unlike sunlight, it does not evaporate moisture from the soil. So you don’t need to water the plants much in one day.

4x4 Grow Tent LED Light Buyer’s Guide

When you are about to purchase a product what do you notice? price? I know the answer.

You set some criteria to define the quality of the product and after that, you check the price. However, here we are mentioning some criteria thus you can select the perfect one for yourself.

Check the Weight of the Product
Weight is a very crucial factor in this case. If you ignore it then your grow tent may fall for a small breeze. However, weight varies on the size of the grow tent. It’s better if you do not cross the limit of 30 pounds in the case of a 4×4 grow tent.

Check the Power Capacity
The wattage capacity is a vital factor here. If it’s not appropriate then you may not get the required spectrums for your plant.

Consider that plant you’re growing:
This is very crucial. Different plants have different requirements of the resources — heat, amount of light (lumen), the wavelength of light, etc. Thus, the first thing you need to consider when buying LED grow lights is what you want to grow under that.

Freedom of Adjustability:
I just told you that you should choose LED grow lights according to the plant you desire to grow. But is it going to be only one plant that you want to grow throughout your life?

No. Also, one particular plant might require a different set of mentioned resources throughout its life cycle.

That is why LED grow lights need to offer the freedom of adjustability. To which extent you can tweak the settings to meet the requirement of a wide range of plants — is something you should consider.

Consider the Heat:
LED grow lights produce good heat when they’re turned on. If you’re growing delicate plants, you should be aware of that. Excessive heat can cause the plants to be burned or scorched. When you’re growing delicate plants, it’s ideal to look for LEDs that produce less heat.

Electricity Consumption vs. Power Output:
Depending on the plants you’re growing, you may need to keep the LEDs turned on for about 10 to 11 hours per day, or even more in some cases. This will add up quite a number to your electricity bill, keep that in mind.

If you’ve got a reason to be worried about that, consider those LED grow lights that give good wattage output consuming less power. There are models that can do that.

How Many LED Watts Are Required Per Square Foot of Grow Space?
It could sometimes depend on the plant you’re growing in that space. But as a simple rule, you need to provide 30 to 40 watts per square foot of grow space.

What Features To Look For In LED Grow Lights?
Low Heat Output: Some cheap LED grow light tends to get overheat and make the environment hot. This could burn plants out. Also, LED grow lights that tend to overheat seem to have a shorter lifespan than the ones that don’t produce excessive heat.

Thus you save some money not having to buy LEDs again and installing them.

LED Grow Light With Cooler: Few LED lights have high-quality cooling fans included in them which internally cools the LEDs. This is great for lengthening the lifespan of the LEDs. Thus, you should look for LED grow lights with a high-quality internal cooling fan.

Quality of the Semiconductor Chip: It is like the heart of a LED grow light, and the heart needs to be of great quality, right? This chip is responsible for converting electricity into light and also determines the wavelength of light.

Make sure you buy a LED grow light with a good quality semiconductor chip that has a minimum wattage of 3.

Best LED Grow Lights — Buyer’s Guide

If you have decided on your LED grow light, here are a few pointers that you should not miss before making the final purchase:

Spacing
This is the first step. Take out your measuring tape as it is better to know accurate measurements than to buy a grow light on an estimated guess. As each light has a specific coverage area it can offer, hence, you need to know what can you fit within the space you have at home. Knowing your space measurements will also help you out in knowing the feedback from reviewers who had the same growth space as you.

Brand / Price
This will be critical as the grow lights offering better quality will generate maximum benefits. If you’re a learner, you’ll probably want to get your feet wet with a low-priced solution. If you’re skilled, you will know that with LED grow lights — good quality means more price. Knowing the product brand and their reliability is equally important. A popular brand with raving reviews is almost always — a safe bet.

Spectrum
A full spectrum LED grow light will help your plants grow to their maximum nutritional value. Depending on the stage of growth, you will need a red and blue spectrum, as well as infrared and ultraviolet lights. To ensure maximum growth, it is important to have a powerful light with different wavelengths.

The industry’s full spectrum yields are slightly newer, but they are quick to take their place in a grower’s catalogue. Full spectrum grow lights run cool and need no extra fans. They save on energy and cost less overtime. Most LED lights have a variety of colors emitted — including the best LED grow lights that have a full range of IV/UR rays.

Electrical Usage
As they use a lot of electricity, it is wise to get a grow light that cuts down on the electricity bills. An average LED grow light operates for around 10 to 12 hours a day. The higher light intensity you choose (1000w, 400w, 300w etc), the lesser electrical usage takes place in the most cost-effective ways.

Light Control
Depending on the stage, you’ll want to ensure that your plants receive the proper amount of lighting (down to the exact hour). It’s extremely important that light cycles are followed to a tee as it can severely alter the growth and potency of your plants.

Conclusion

To sum things up, the best-LED light doesn’t come easy. You will have to go through quite a lot of considerations to make sure you are getting the best thing for your setup. Not every option will be suitable for everyone, so you must choose based on your preferences.

Commercial Greenhouse Grow Lights

Horticultural lighting poses unique problems. Many commercial greenhouse grow lights are installed using LED lighting or Sodium Lights (High Pressure Sodium Grow Lights — HPS). Which one is a better solution is a common question. LED grow lights are rather new to the horticultural lighting world, where HPS grow lights have been around for quite some time. There are grow forums around the world who can debate a pro and con list that will equal at any length. So often times, commercial greenhouse grow lights are chosen based on past experience. The horticultural lighting migration from incandescent to fluorescent to high intensity discharge (HID) halogen, to high-pressure sodium (HPS) to LED has taken time; however, renewed interest in energy conservation and novel production is fueling a rapid growth in LED technology.

Commercial Greenhouse HID Grow Lights

HPS grow lights produce a massive amount of raw light output. That is the key to their popularity. This intensity can produce great crop yields which is ideal when working with very large plants. But this lighting intensity also has the downside of using more electricity, generates more heat which increases costs for maintaining grow room temperatures with the necessity for added ventilation, and HPS grow bulbs often need replacement every 12–18 months. All of this adds to higher operation costs using HPS as your horticultural lighting solution.

HPS (High Pressure Sodium) lighting is the most popularly used light source with a proven track record for cannabis growers, providing bright, intense light with a reasonably long lifespan.

• Provides a wide spectrum of light colors
• Fairly efficient and less costly when comparing output per wattage
• Smaller in size than LPS or fluorescent lights
• Cheaper alternative to other options on the market
• Provides extra heat which is very beneficial to the marijuana plants in the winter
• GGS can help with supplemental cannabis greenhouse lighting and with primary lighting for indoor marijuana grows

Commercial Greenhouse LED Grow Lights

LED grow lights are without question the most efficient lighting type available resulting in huge savings on your power bill. LED grow lights emit very little heat which makes them ideal for indoor growers especially those using vertical farming methods. LED fixtures are manufactured as a single encased fixture which makes them easy to handle and reduces their size making them ideal for tight spaces. LED fixtures run higher in price than HPS grow lights, but their reduced operating costs pay back in dividends. Colder climate greenhouses and grow rooms using LED horticultural lighting may need to supplement the heat source of your indoor area to help maintain desired growing temperatures.

Cannabis growers are taking advantage of the energy savings that LED marijuana grow lights can provide.

• Can cut energy use in your cannabis grow facility by up to 75%
• Yield benefits can offer far beyond kWh savings
• Provides the wavelengths and intensity you need with adjustable-spectra LEDs
• Lower maintenance and reduced maintenance costs as diodes last much longer than conventional bulbs
• Flexible light adjustment; they can be dimmable or can be turned onto full instantly
• Available in a variety of temperatures for color accuracy
• Fixtures can be placed closer to marijuana plants for greater efficiency
• Multiple level cannabis growing is possible
• Reduced wire size and associated wire costs

FLUENCE SPYDR 2P LED GROW LIGHT SYSTEM

The Fluence SPYDR 2p is an improved, more powerful version of the SPYDR Plus. Just like the 2i, the SPYDR 2p is developed for High PPFD Cultivation, which makes the grow light in principle suited for growrooms in which extra CO2 is added to the air. A boosted quantity of CO2 of 800 to 1,400 PPM (normally this is 400 PPM, 0.04%), in other words, a percentage of 0.08 to 0.14%, will enable a plant to safely transform that huge light intensity into carbohydrates and energy. The beneficial effect for the grower is that, due to this, the life cycle of his plants is significantly accelerated and, additionally the yield is increased up to 20%. I.e.: High PPFD Cultivation will generate more crop in less time.

The SPYDR 2p resembles the 2i in many aspects, but the most important difference is the light intensity. The 2p is less powerful which makes this LED nursery lamp in principle also suited for growers that work without CO2. It is important however, to keep a minimum of 40 centimetres between lamp and plant. At a shorter distance, the light intensity will damage the plants.

The Fluence SPYDR 2p is fitted with a PhysioSpec Indoor spectrum, developed by Fluence themselves. This is a tailor-made spectrum for the indoor grower and intended for the entire life cycle of your plants. So, also seedlings, shoots and clones will feel very comfortable in the light of this lamp. The PhysioSpec Indoor spectrum scores 85 on the CRI-scale, meaning that the radiated light is excellently suitable for the work and research conditions in which natural, lively colours and proper contrast are essential. The Fluence SPYDR 2i does not include a built-in dimmer. This can be obtained separately only. One dimmer can be connected up to 50 SPYDR 2s.

The Fluence SPYDR 2p is a professional LED grow light, highly efficient in energy consumption. Thanks to the large light surface, the light is distributed quite evenly across the growth surface and will have no trouble penetrating the foliage. The materials used by Fluence, the straightforward design and the lack of fans make the Fluence SPYDR 2i a soundless, solid grow light that will last for many years, hassle-free. The Fluence SPYDR 2p can be connected to the mains electricity as stand-alone or in daisy-chain. This LED grow light is suitable for use in racking (vertical farming), cultivation tables and in grow tents. A hanging fixture is included.

High PPDF-growing with CO2 requires knowledge of photosynthesis and the effect of CO2 on your plants. It is important to realise that in case of too little CO2 in the air, the bright light cannot be transformed into energy and carbohydrates, as a result of which your plants may get damaged. On the other hand, the additional CO2 in the growing area will only be transformed in case there is sufficient light intensity. Using the powerful Fluence SPYDR 2p that is one thing you needn’t worry about.

How much area are you looking to light?

The best place to start is to figure out the square footage of the area you are trying to light. For high-light plants like tomatoes you will want to achieve around 40 watts per square foot for optimal growth and fruit production. For low light plants, and small leafy plants like herbs and lettuce, you will only need to achieve about 25 to 30 watts per square foot. When figuring your area don't necessarily go by the actual size of the room. You will want to measure only the plant area that you will be growing in. In other words, if the grow room is 5 x 5, but you will only be growing in a 3 x 3 area there is no reason to get a light big enough for the whole room. Using that as an example, you have a 5x 5 growing area so you must figure out how many watts you will require to light that area. We will be growing tomatoes so we will want to achieve 40 watts per square foot.

Width x Depth = Square Feet, e.g. 5 x5= 25 sq. ft.

Watts x Square Feet = Desired Wattage, e.g. 40 x25 = 1000 watts

We will just round the 900 watts up to 10000 watts. So, we know that we will be in the market for a 1000 watt LED grow light...

Factors to Consider When Buying a 1000 Watt LED Plant Light

Actual Wattage
This is the actual amount of electricity the fixture will use. Three of the lights featured here always use the same wattage, while the other one has a range. That's because it gives you some control over the spectrum.

During the vegetative stage of growth, for example, plants don't need as much light as they do during flowering. A fixture that lets you turn off LEDs (or dial back their intensity) when they are not needed will save you money in electricity costs.

Light Output
1000w LED grow lights generally have an output equal to 900 watts of HPS light, despite what many manufacturers claim.
For our ratings, we gave 4 stars to the fixtures whose intensity is about equal to 900 HPS watts and 5 stars for an intensity better than a 1000 watt HPS bulb.

Coverage Area
This is the area in feet that the light will cover during flowering. During vegging, they can cover an additional foot or two in length and width. So a light that covers 4 by 4 feet during flowering will cover 5 by 5 or 6 by 6 feet during vegging.
