<\/span>Growing plants indoors\u2014especially cannabis\u2014isn\u2019t always easy. Although LED grow lights have been around for over 50 years, they\u2019re still considered a relatively new technology.<\/p>\n\n\n\n

LED marijuana grow lights are making the lives of hobbyists and professionals much easier. Thanks to technological advancements, LED lights are increasing in power while becoming more affordable.<\/p>\n\n\n\n

The best LED grow lights don\u2019t just encourage growth and produce higher-quality yields. They\u2019re also durable and will help you save on electricity. They do this by replicating the wavelengths and spectrum of the sunlight.<\/p>\n\n\n\n

With many options available and a lot of misleading information out there, choosing the best LED grow light can quickly become overwhelming. I\u2019m here to help\u2014by sharing some general information and things you should consider. And of course, to give you my top recommendations.<\/p>\n\n\n\n

Do LED Lights Make Good Grow Lights?<\/h2>\n\n\n\n

LED lights are the most popular choice of grow lights for weed. Before selecting your specific set of LED grow lights, let\u2019s take a look at what makes them so popular to growers.<\/p>\n\n\n\n

Benefits of LED Grow Lights<\/h3>\n\n\n\n

What are the benefits of adding LED lights to your growing room? There are actually quite a few\u2014for your plants, for your wallet and for the environment.<\/p>\n\n\n\n

Energy Saver<\/h4>\n\n\n\n

Fluorescent and incandescent lighting emit light in a 360-degree direction. LED lights, however, emit light in only one specific direction. As a result, LED lights use 90 and 60 percent less energy<\/a> (respectively) than their counterparts.<\/p>\n\n\n\n

Durability<\/h4>\n\n\n\n

Compared to incandescent or fluorescent lights, LED lights are also able to withstand higher levels of shock and vibrations.<\/p>\n\n\n\n

A typical LED light should last about 50,000 hours. This is two to three times longer than fluorescent lights, and 50 times longer than incandescent light bulbs. Some of the best LED lights for growing cannabis<\/a> can even have a lifespan of up to 100,000 hours.<\/p>\n\n\n\n

Instant Lighting<\/h4>\n\n\n\n

Fluorescent lights can take some time to reach their full brightness, which could result in wasted time. LED lights, on the other hand, light up fully as soon as they are turned on.<\/p>\n\n\n\n

Environmentally Friendly<\/h4>\n\n\n\n

Most LED grow lights for cannabis don\u2019t contain mercury or any toxic materials. This makes them easier to dispose of, as well as causing less of an environmental risk.<\/p>\n\n\n\n

Don\u2019t forget that they last longer and are more energy efficient. This makes them less wasteful, and of course they don\u2019t have to be replaced as often. In an age where we are trying to minimize waste, this is a big plus.<\/p>\n\n\n\n

Less Heat<\/h4>\n\n\n\n

LED lights typically come with one to four fans to keep your lamp\u2014and therefore your plants\u2014from overheating. By reducing the risk of fire, it also makes them safer. Cool lights mean a longer lifespan and improved plant health.<\/p>\n\n\n\n

\u201cDo It Yourself\u201d LED<\/h4>\n\n\n\n

If you\u2019re keen on DIY and wish to have a go at building your own LED light, this video might be helpful.<\/p>\n\n\n\n

Worth the Higher Price<\/h3>\n\n\n\n

While LED lights are the number one choice for growing marijuana, they are not without their limitations. The best LED grow lights, unfortunately, represent a significant initial investment. Most growers find that the results are well worth it in the end, though.<\/p>\n\n\n\n

Are LED Grow Lights Better Than HPS?<\/h2>\n\n\n\n
\"closeup<\/figure>\n\n\n\n

<\/span><\/p>\n\n\n\n

You might speak to some growers who have a preference for HPS (high pressure sodium) lights. Since I prefer LED lights for growing cannabis, I thought it would be helpful to share some of the reasons why.<\/p>\n\n\n\n

Less Heat Output<\/h3>\n\n\n\n

LED lamps produce 90 percent less heat than HPS lights. The decreased heat will contribute to healthier plants. In the summer or in warmer climates, this also means savings on air conditioning or other cooling costs.<\/p>\n\n\n\n

Energy and Cost Saving<\/h3>\n\n\n\n

The best LED grow lights also consume less energy than HPS lights. Most users who switch see a noticeable difference in their electric bills.<\/p>\n\n\n\n

Some people argue that you need to use more LED lights in order to match the output of HPS lights. Even so, the energy savings means that LED lights, even if you use more of them, still save you money.<\/p>\n\n\n\n

LED lights last longer and often have warranties, which means additional savings. HPS lights usually need to be replaced every year. They also don\u2019t come with built-in fans, so you\u2019d need to purchase an exhaust system.<\/p>\n\n\n\n

Easier Installation<\/h3>\n\n\n\n

LED lamps are easier to install and can simply be hooked to a wall, without heavy duty equipment.<\/p>\n\n\n\n

Yield Quality<\/h3>\n\n\n\n

When using LED lights, growers report higher quality buds, with better taste and brighter colors. HPS lights seem to grow bigger yields, but not at the same level of quality.<\/p>\n\n\n\n

If you\u2019re transitioning from HPS to LED, both types of lamps can be used in a single grow room\u2014HPS lights are mostly used during the flowering stage.<\/p>\n\n\n\n

What Size LED Grow Light Do I Need?<\/h2>\n\n\n\n

Spacing will be key when it comes to choosing the best LED grow lights. Because each light is only able to cover a specific surface, it\u2019s important to know the precise measurements of the area you plan to grow. To grow properly, each cannabis plant usually needs one square foot.<\/p>\n\n\n\n

If you\u2019re unsure of exactly how much space you have, take measurements. Your available growing space will determine the number and the size of LED lights you\u2019ll need.<\/p>\n\n\n\n

During the vegetative state of growth, most growers use 32 watts of power for each square foot. During the flowering stage, however, your plant needs additional lighting and 50 watts of energy per square foot will be required.<\/p>\n\n\n\n

Let\u2019s take an example. If your canopy measures 3 feet wide and 4 feet long, your growing space equals 12 square feet. Multiply this number by 32 and you find that 384 watts are required during the vegetative growth. Once the plant is about to bloom, increase the lighting to 600 watts minimum (12 square feet x 50).<\/p>\n\n\n\n

Here is a table for of energy requirements for the flowering cycle that I think is very helpful.<\/p>\n\n\n\n

Should My LED Light Contain UV Wavelengths?<\/h2>\n\n\n\n

Some of the best grow lights for weed also provide infrared and ultraviolet wavelengths. UV lights are known to damage the plant\u2019s DNA. As a way of defending itself against this, the cannabis plant raises its production of THC<\/a> (tetrahydrocannabinol) by 20 percent.<\/p>\n\n\n\n

This defense mechanism actually increases the potency of the yield.<\/p>\n\n\n\n

To avoid harming the plant, the key is to find the right balance. When UV lights are used frequently, they bring smaller but more potent yields. Used from the seedling growth stage, UV light will grow your plants into strong and resistant yields as they mature.<\/p>\n\n\n\n

It\u2019s important to know that UV lights lower CBD<\/a> (cannabidiol) levels, and are therefore not for every grower. If you\u2019re trying to grow a crop with that\u2019s stronger in CBD, you should probably avoid ultraviolet lights.<\/p>\n\n\n\n

Finally, UV lights can keep your crop strong and healthy by reducing the development of fungal bacterias.<\/p>\n\n\n\n

Best LED Grow Lights: Key Points to Consider<\/h2>\n\n\n\n

I hope you now have a better understanding of the comparative advantages of using LED grow lights for cannabis. Before I give you my product recommendations, here are some key points you should be taking into consideration.<\/p>\n\n\n\n

What Are You Growing?<\/h3>\n\n\n\n
\"led<\/figure>\n\n\n\n

<\/span><\/p>\n\n\n\n

Before purchasing any grow light, you\u2019ll need to consider the type of cannabis you\u2019re planting. Some of the most popular weed varieties are ruderalis, hybrid sativa dominant, pure sativa, pure indica, and hybrid indica dominant.<\/p>\n\n\n\n

Depending on the species, you may have to adapt your lighting. For instance, the indica species only require eight hours of light per day, while sativa species require almost 13 hours of daily light.<\/p>\n\n\n\n

Will you be planting seeds or already matured crops? Your cannabis plant needs different types of wavelengths depending on their maturity level\u2014seeds, young plants, or a fully grown crop.<\/p>\n\n\n\n

Choose Quality Materials<\/h3>\n\n\n\n

The wrong lighting has the power to destroy your crop in only a few days. Investing in high-quality indoor grow lights might be an investment, however, it will ensure the optimum health and growth of your cannabis in the long run.<\/p>\n\n\n\n

Each bulb should contain at least 3 watts of power, therefore the chip needs to be durable and well built. In most cases, manufacturers state the light\u2019s lifespan on the packaging. The best LED grow lights will last from 50,000 to 100,000 hours, so you won\u2019t have to worry about replacing them for quite some time.<\/p>\n\n\n\n

Many of the best LED lights for growing cannabis are manufactured in the United States, meeting stringent quality standards. They\u2019re mainly made of steel, aluminum or other sturdy materials. To improve nutrient penetration by 25 percent, an optical lens is sometimes added.<\/p>\n\n\n\n

Are you looking at two lights, with a similar look but vastly different costs? The quality of materials is usually the reason why.<\/p>\n\n\n\n

What Kind of LED Light?<\/h3>\n\n\n\n

As the industry is moving towards fully automated lighting systems, the best LED grow lights come with the ability to customize spectrums and intensities. Marijuana grow lights can also come in several shapes, each fitting different types of crops.<\/p>\n\n\n\n

Quantum board<\/strong> lighting is a term used when lights are set up on a large board spread out over your canopy. They seem to have a fairly low wattage power, while still providing good results for the number of watts used.<\/p>\n\n\n\n

Spider style<\/strong> lights are similar to quantum boards, and the small diodes are positioned in a large flat surface. The panel, however, is spider-shaped, expanding in different directions. These tend to have a slightly higher price tag.<\/p>\n\n\n\n

COB Style<\/strong> LEDs have larger diodes. Instead of using many small diodes, this lighting system uses fewer but stronger lights with lenses. These lenses allow a deeper light penetration within your growing space.<\/p>\n\n\n\n

The traditional panel<\/strong> contains slightly larger diodes than quantum, and benefits from features of both quantum board and COB style lighting systems.<\/p>\n\n\n\n

While saving electricity is important, you also want to make sure you get the right amount of power to grow your cannabis. Panels help spread the light over your grow area. If you have a substantial growing surface, a minimum of two panels is recommended.<\/p>\n\n\n\n

Electricity Consumption & Output<\/h3>\n\n\n\n
\"power<\/figure>\n\n\n\n

<\/span><\/p>\n\n\n\n

Your marijuana grow lights will be running for 10 to 18 hours per day. Too much light and you run the risk of burning your plant; not enough light and your cannabis won\u2019t grow as expected. A good balance is crucial to obtain the best quality yield.<\/p>\n\n\n\n

You\u2019ll find grow lights for weed available from 12 watts of power, all the way up to 3000 watts. It\u2019s best to have a close look at the labels before making a decision. To compare different full spectrum LED grow lights, look for the \u201cactual power consumption\u201d or \u201cactual power draw\u201d on the product description.<\/p>\n\n\n\n

Unless you\u2019re growing a single plant, your light\u2019s electrical output shouldn\u2019t be less than 300 watts. The higher the output, the more light your plants will receive.<\/p>\n\n\n\n

It\u2019s best to spread the light throughout your canopy. You will likely have better results with several smaller LEDs rather than a single larger one. For instance, it might be best to purchase two 200-watt LED lights than one 400-watt light.<\/p>\n\n\n\n

Always keep in mind that a fraction of the power might get lost before it reaches your plant. This means that your cannabis won\u2019t receive 100 percent of the power announced on the label.<\/p>\n\n\n\n

What Is PAR?<\/h3>\n\n\n\n

Manufacturers often use the term PAR, or photosynthetically active radiation. PAR represents the actual amount of light available for the photosynthesis process. This is a very import measure when growing your cannabis.<\/p>\n\n\n\n

Here are some guidelines to keep in mind for each stage of the plant\u2019s growth:<\/p>\n\n\n\n

\n

Using a grow light with a lower PAR than indicated above won\u2019t kill your crop, but will slow down its growth. The best LED grow lights will have the highest PAR.<\/p>\n\n\n\n

Lumen, on the other hand, measures the amount of light\u2014or brightness\u2014that the LED generates. This isn\u2019t always relevant for us because the plant won\u2019t be necessarily using the full amount of light for photosynthesis.<\/p>\n\n\n\n

Which Beam Angle Do I Need?<\/h3>\n\n\n\n

When looking at the product description, you\u2019ll see information such as 60, 90 or 120-degree beam angle. What does it mean and which one should you choose?<\/p>\n\n\n\n

If you\u2019ve owned HPS lights, you\u2019ll know that they\u2019re all made with a 360-degree beam angle. With no control over the angle width, they\u2019re wasting a lot of unnecessary energy\u2014which is why reflectors are needed.<\/p>\n\n\n\n

With the best LED grow lights, each diode\u2019s beam angle can be controlled. Note that the beam angles don\u2019t represent the angle from the light fixture, but the angle from each LED diode.<\/p>\n\n\n\n

A 120-degree beam angle\u2014the largest width\u2014will cover a larger surface yet with the less intensity. A 60-degree beam angle is more focused and concentrated in one particular area, allowing the light to penetrate deeper in the canopy. Most growers prefer a narrow beam angle with higher intensity.<\/p>\n\n\n\n

What Are Primary and Secondary Lenses?<\/h3>\n\n\n\n

Primary lenses are located right where the light is emitted by the diode, enabling the light to leave the silicone efficiently. Without this primary lens, the light would never reach your plants.<\/p>\n\n\n\n

Placing a secondary lens just underneath the primary lens will change the direction of the light stream, creating a narrower\u2014or wider\u2014angle. Secondary lenses are also sometimes called \u201coptics\u201d by manufacturers.<\/p>\n\n\n\n

A lot of incorrect information circulates about secondary lenses. It\u2019s important to understand that they don\u2019t increase the overall intensity of the light, they simply redirect the energy into a specific direction. In fact, you could actually lose eight to 15 percent of the total energy in the process.<\/p>\n\n\n\n

If you\u2019ve chosen the right LED light with the appropriate brightness, secondary lenses might not be necessary.<\/p>\n\n\n\n

Quality Semiconductor Chip<\/h3>\n\n\n\n

Would you consider purchasing a car with a weak engine? Not very likely. The same concept applies to your LED light.<\/p>\n\n\n\n

The semiconductor chip is considered your light\u2019s engine. It transforms electricity into light, affecting the wavelength. Each chip should use at least three and up to 10 watts, to provide the necessary lighting.<\/p>\n\n\n\n

Full Spectrum Lights<\/h3>\n\n\n\n

While most cannabis plants grow under all spectrums of lights, they grow best under full spectrum lights.<\/p>\n\n\n\n

These full spectrum lights are fairly new to the market but are quickly gaining in popularity. They\u2019re able to emit different wavelengths necessary throughout the different growth stages<\/a>. The best LED grow lights will provide both red and blue lights.<\/p>\n\n\n\n

Blue lights<\/a> imitate the sunlight typically found in summer and help the plant spread its leaves for optimum photosynthesis and growth. Cannabis plants need this wavelength\u2014400nm to 500nm\u2014throughout the vegetative state. When used through the whole growing period, your crop might develop short stems and large leaves.<\/p>\n\n\n\n

Fall sunlight is imitated by red or yellow lights\u2014640nm to 660nm\u2014which are needed during the flowering cycle. These wavelengths encourage your crop to grow high and produce the flowers and buds you\u2019re longing for.<\/p>\n\n\n\n

One of the main advantages of full spectrum LED grow lights is the ability to customize the wavelength and amount of light needed just at the push of a button.<\/p>\n\n\n\n

They also tend to emit less heat, not only saving you the cost of buying extra fans, but also on electricity.<\/p>\n\n\n\n

Heat Levels<\/h3>\n\n\n\n

For optimum growth, LED grow lights are hung just above the plant. Lights generating high heat can burn the leaves or make them turn into a yellow-brownish color. Low emission grow lights<\/a> can be placed in closer proximity to the plant without the risk of burning it.<\/p>\n\n\n\n

High heat LED lights also tend to dry up the air. Cannabis grows best in tropical climates and environments, and low heat lights help you maintain a good humidity level throughout your growing area.<\/p>\n\n\n\n

Low heat lights give you an extra hand keeping the room temperature under control, which will help you save on electricity. They also tend to have a longer lifespan, since high heat outputs burn out the lights faster.<\/p>\n\n\n\n

Internal fans should be built into your LED light. In addition, to allow good ventilation, an aluminum heat sink<\/a> should be attached to that back area, preventing the chip from overheating.<\/p>\n\n\n\n

Usability and Flexibility<\/h3>\n\n\n\n

Time is money, and the last thing you probably want is to spend hours installing your brand new lights. The best indoor grow lights can be installed without effort, and allow easy height adjustments. Many grow lights for weed even come with a power cord and a hanging hook, and can be used straight out of the box.<\/p>\n\n\n\n

This isn\u2019t relevant only for the initial installation. You might find that you want to adjust your LED lights\u2019 positioning according to the growth stage.<\/p>\n\n\n\n

LED Grow Lights for Grow Tents<\/h3>\n\n\n\n
\"lighting<\/figure>\n\n\n\n

<\/span><\/p>\n\n\n\n

Grow tents are great for growers with limited space, and for beginners new to growing cannabis indoors<\/a>.<\/p>\n\n\n\n

Many grow tents<\/a> only come with a growing room, and it will be up to you to choose the ventilation, lighting system, and everything else.<\/p>\n\n\n\n

Keep in mind, however, that if you\u2019re growing your crop in a 4-foot by 4-foot tent, you\u2019ll end up with a real growing space of 3 feet by 3 feet. This will be the volume to consider while choosing your LED light.<\/p>\n\n\n\n

For beginners, I recommend grow tent kits. They come with everything you need for your plants\u2019 optimum growth, including the proper LED lights.<\/p>\n\n\n\n

\u200bReturn Policy and Warranty<\/h3>\n\n\n\n

The best LED grow lights should last for about 10 years. Manufacturers who guarantee a shorter period of time should be treated with caution. You should be especially wary of LED grow lights that that only have a one-year warranty.<\/p>\n\n\n\n

The good news is that the best LED lights for growing cannabis are composed of several parts which can function independently. You should still be able to use your light while waiting for your spare part replacement.<\/p>\n\n\n\n

Safety & Certifications<\/h3>\n\n\n\n
\"electrical<\/figure>\n\n\n\n

<\/span><\/p>\n\n\n\n

There are a few different safety certificates you should be aware of. Restriction of hazardous substances, or RoHS, is a good indicator of the LED safety and quality, yet not always the most relevant.<\/p>\n\n\n\n

It only restricts the use of specific materials used in electronic products. These include cadmium, lead, chromium, mercury, polybrominated biphenyls, hexavalent, and polybrominated diphenyl ethers.<\/p>\n\n\n\n

ETL or UL safety certificates are from third-party organizations. They provide independent quality and safety certifications, both under the name of nationally recognized testing laboratories (NRTL).<\/p>\n\n\n\n

Avoiding Common Mistakes With LED Lights<\/h2>\n\n\n\n

Once you\u2019ve selected your LED grow lights, it will still take time and experience to obtain the best yield. Here are tips I wish I had been given when I acquired my first LED lamp.<\/p>\n\n\n\n

Burning Your Cannabis Plant<\/h3>\n\n\n\n

If the leaves are turning yellow or brown, or if they\u2019re curling up, this is a sign that your plant is getting too much light.<\/p>\n\n\n\n

It usually starts from the outer side of the leaf, making its way to the center. If immediate action is taken-\u2014less light and good ventilation-\u2014it can be reversible.<\/p>\n\n\n\n

Insufficient Lighting<\/h3>\n\n\n\n

Because plants feed on the light source to produce photosynthesis, providing insufficient lighting will slow the growth of your crops.<\/p>\n\n\n\n

Calculate your growth area and make sure that you have enough LED lamps to cover the entire surface.<\/p>\n\n\n\n

Proper Light-to-Plant Distance<\/h3>\n\n\n\n

To ensure the right lighting, LED lights shouldn\u2019t be placed too close or too far from your crop. This can lead to overheating or insufficient lighting.<\/p>\n\n\n\n

It\u2019s recommended to position them 12 inches (for 1-watt chips) to 18 inches (for 3-watt chips) away from the plant. If you\u2019re unsure, it might be best to contact the manufacturer.<\/p>\n\n\n\n

Improper Light Schedule<\/h3>\n\n\n\n

During the vegetative state, cannabis plants need about 18 to 24 hours of direct light. They require around 12 hours during the flowering cycle. Even a slight change in this schedule can have a major impact on your plant\u2019s health.<\/p>\n\n\n\n

On a similar note, a lighting regimen excluding a dark period decreases the ability of the plant to undergo photosynthesis. Weak development and lack of strength will result. Don\u2019t forget to turn the lights off at the end of the day!<\/p>\n\n\n\n

Light Adjustments<\/h3>\n\n\n\n

As your plant grows, the light should be adjusted with the proper wavelength. Pots should also be moved around to avoid the plant leaning toward one side or another, trying to reach for the light.<\/p>\n\n\n\n

Proper Maintenance<\/h3>\n\n\n\n

The best LED grow lights represent a certain investment, yet requiring minimal maintenance. I\u2019d recommended setting up a power stabilizer. This will help to ensure that all the lights receive the same amount of power, protecting the chip.<\/p>\n\n\n\n

Try keeping your lights away from bugs, smoke, or even dust. Their accumulation inside the lamp will make the light heat up more than it should, potentially burning the diode.<\/p>\n\n\n\n

Overwatering<\/h3>\n\n\n\n

The best LED grow lights won\u2019t generate a lot of heat. Not much water is lost through evaporation and irrigation should be kept to a minimum. Many growers going from HPS to LED lights have accidentally harmed their crops initially, due to overwatering.<\/p>\n\n\n\n

When the plant is over saturated with water, oxygen isn\u2019t able to enter through the root system. Bacteria can also develop, eating up not only the roots of your crops but also the nutrients found in the soil. I\u2019d recommend allowing the soil to dry before watering again.<\/p>\n\n\n\n

If you notice the leaves wilting, you\u2019re probably over-watering your plant.<\/p>\n\n\n\n

Plant Chemistry: Nutrients, pH and Carbon Dioxide<\/h3>\n\n\n\n

While LED lights are a great help when it comes to growing indoor plants, other factors will make or break a successful yield. It\u2019s important to understand the full picture and complete cycle to reach optimum growth.<\/p>\n\n\n\n

Without the proper nutrients, your plants won\u2019t reach their full potential. Nitrogen, phosphorus, and potassium are considered the main food source for cannabis. Sulfur, calcium, and magnesium are also important, and fertilizers can be added if needed.<\/p>\n\n\n\n

An optimum growth can be reached, with a pH ranging from 5.8 to 6.5 and a temperature between 75 and 86 degrees Fahrenheit. When temperatures drop below 60 degrees or reach 88 degrees Fahrenheit, this can impact the THC potency.<\/p>\n\n\n\n

For the plants to grow efficiently, the levels of carbon dioxide should be sufficient and maintained. CO2 can be made at home<\/a> using dry ice, a milk jug and a yeast solution mixture, carbon dioxide generators, vinegar and baking soda mixture, or even by using a bottled carbon dioxide.<\/p>\n\n\n\n

LED Grow Lights Yield and Production<\/h2>\n\n\n\n

Many new growers ask how much cannabis they will yield using LED grow lights. Unfortunately, there isn\u2019t a definitive answer to this question; many factors need to be considered.<\/p>\n\n\n\n

The yield will largely depend on your experience growing cannabis, the strain of weed you\u2019re growing and the quality of the lighting provided. Many hobbyist growers generalize that obtaining 0.5 grams per watt is a good yield, while 1 gram per watt is an excellent yield.<\/p>\n\n\n\n
