How to build?

Before we move onward to a DIY assemblage of the grow light systems, prerequisite knowledge of some terms associated with the lighting system, plant response to the types of light arrangements, and the equipment in use is necessary. Let’s have a brief about them.
Light possesses several features that affect the growth and development of plants including the intensity and the quality of light, uniformity and angle, brightness and direction that determine the process of photosynthesis and physiological processes. Chlorophyll is the driving force in photosynthesis that absorbs the wavelength of varying intensities from 400 nanometers to 700 nanometers often called PAR or PPFD with its peak absorption from 600-700 nm in the red and 400-500 nm in blue wavelength of light. PPFD is measured in μmol m-2 s-1 that is an outcome of the DLI-Daily Light integral and period of light by the source in 24 hours and is directly connected with the production of biomass by absorption of nutrients and water by the plants in that time.
The quality of light is the combination of the spectrum that enables different processes of growth and development in plants along with controlling the plant’s metabolic activities that concentrate on the quality of the product like color, taste, and maturity by maintaining it genetic and phenotypic characteristics.
Ultra Violet Spectrum (200-400 nm): It reduces the growth of fungus and is responsible for inducing resistance in the plants against diseases and pests along with stimulating pigmentation in leaves for further vegetative growth.
Blue Spectrum (400–500 nm): It controls stomatal opening in the leaves, helps in the vegetative growth stimulation and foliage development.
Green Spectrum (500–600 nm): It controls stomatal closing and maintains a balance of the moisture in the plant tissues while initiates photosynthesis in the deep tissue of leaves.
Red Spectrum (600–700 nm): It controls stem elongation, internodal distances, and hormones that control pollination and fertility of the plants.
Far-red Spectrum (700– 800 nm): It controls stem elongation, induces flowering, and the maturity processes.

#1 LED Drivers

LEDs perform better under low voltage so AC needs to be converted to a stable DC for their smooth functioning. DC to DC converters is best to drive them with the step-down options and regulators that make them efficient and energy saving. The drivers with the low DC input are preferred over AC drivers with a minimum output of 5 Volts and 5 Amperes.

#2 Heat Dissipation

The LEDs are generally associated with producing low heat that is controlled through active and passive heat sink methods. Heat dissipation is generally controlled through aluminum sinks in the passive cooling system while in the active heat sinks additional airflow is maintained using extra exhaust fans to keep the system cool and to avoid high temperatures.

#3 Dimmable options

LED light dimmers are an effective technique to control the brightness options at the different stages of the plant’s need. Another option is to install pulse-width modulation switch to the source and program it to switch up and down for the brightness control using a sensor or an analog dimmer can also be used instead of PWM switch that needs constant attention of the growers for brightness control.

DIY Installation for Panel

The first step is to ensure that each LED is connected in series with the MOSFET. All the power that comes to these LEDs will be controlled by utilizing Arduino PWM (Pulse width modulation) pin. The Arduino helps in complete separate control for all the different LED colors and thus helps in maintaining the required lighting. All the LEDs of a single color should be connected in series in the form of an array. Different LEDs’ types should be joined in separate PWM pins of Arduino.
This separate Arduino connection comes handy when you want to leave room for further adjustment or want to add more LED depending upon the requirement. The LEDs produces heat with light too, to overcome this issue, all the LEDs are held in place with the thermal tape in an Aluminum heat sink. This helps in even heat distribution and helps to avoid overheating.
The LEDs are further connected with a power supply with the help of a voltage regulator. The voltage regulator, here, helps in supplying a smooth and thorough voltage to the LEDs, ensuring the smooth and uniform running of the LEDs.
For the best quality of light, all the LEDs should be placed evenly over the surface. It is better to draw a diagram before going for the physical installation so that all the steps are carried out proficiently without hassle. The successful completion of a diagram will help you to connect all accessories and drivers more precisely.

Best Bulbs for Growing Plants: Different Types Available

As you try to make the right decision, one of the first things that you have to be familiar with would be the different types of grow bulbs that are available. That being said, here are some of the choices that are available:

• Single-Ended Light Bulbs: As the name implies, it comes with a single end, which attaches directly to the socket, often connected to a reflector or hood that maximizes the light that is reflected.
• Double-Ended Light Bulbs: Contrary to the light bulb that has been mentioned above, there are two ends that connect to two different sockets. It usually has a more powerful light output, which makes it a great choice if you have a big grow room. It is also more expensive compared to its counterpart.

LED vs CFL vs HID Grow Light Bulbs

When searching for the best grow light bulb, LED, CFL, and HID are three of the words that you will often encounter. They actually refer to different kinds of light bulbs. This section will quickly explore the similarities and the differences between the three.

• LED Grow Bulbs: If there is one thing that many people love about LED, it would be the fact that it is the most energy-efficient from the three types that are available. They also remain cool even when left turned on for an extended period. The initial cost of acquiring LED, on the other hand, can be quite steep for some users.
• CFL Grow Bulbs: Compact Fluorescent Lighting are cheaper, but they are also less powerful when compared to the two types. It is known for generating a minimal amount of heat, which makes it a great choice when starting the plant. If you are looking for the best light bulb for clones, CFL will be an unmatched choice.
• HID grow Bulbs: This can be further divided into two: High-Pressure Sodium and Metal Halide Bulbs. They are a favorite amongst weed cultivators because of the amount of the usable light that they are able to produce. The growth rate is also the fastest with this light bulb. However, you will need a special type of ballast and hood for this type.

Types of Grow Light Bulb Sockets

It is also important to be familiar with the different sockets or bases that are available. The end of the light bulb must perfectly fit on the base when it is screwed. In this case, these are the options that are available:

• E12: Also known as the candelabra, this is the smallest screw base for a grow light bulb. This also tends to be weak, making it great only for clones or for seedlings.
• E17: This is a size that is popular in Europe and in China. As with the other bulbs that are mentioned in this guide, E stands for Edison while the number stars for the millimeter of the base of the light.
• E26: This is the standard size of the light bulb socket, which makes it the most popular in North America. In Europe, its equivalent is the E27. Aside from grow rooms, it has a wide array of applications, such as general lighting fixture at home.
• E39: The E39 is used in North America and the E40 is in Europe. They can be used interchangeably as there is only 1mm difference. If you need grow light bulbs with a powerful output, this is what you should choose.

Factors to Consider When Choosing the Best Bulbs for Growing Weed

When choosing from the products that are available on the market, here are some of the most important things that you need to take into consideration:

Wattage: How many led watts per weed plant?

You need to consider the size of the grow room and the plants that are inside to determine the right wattage of the light bulb to buy. For a small grow room with only one or a few plants, you will already be good with a light that has a minimal wattage. If the grow tent is large, you need a more powerful light or use several light bulbs.

Spectrum: What is the best color spectrum for weed plant?

More often than not, the light can be red, blue, or a combination of both. Consider the stage of the plant to determine the spectrum that is best. If it is solely for flowering, red is the most important.

Ease of Use: How to build a grow room?

For the light bulb to be user-friendly, one of the most important is to have the right socket. The standard socket is E27, which means that compatibility will not be a problem. In some cases, you need to install a new socket that will fit the light that you will be using.

Heat: How to prevent heat stress in weed?

When choosing the best bulbs for growing plants indoors, you also need to think about the amount of heat that it can generate. Choose a light bulb that stays cool even when used for a long time, which means that it will not cause stress to the plant. Also, pay attention to the height of the light when it is installed.

Energy-Efficiency: What type of light is best for growing weed indoors?

This is important if you have a large grow room, especially if you are a commercial cultivator. Look for grow light bulbs with Energy-Star certification, which means that it uses less electricity in the absence of compromising performance.

Warranty: What makes a good grow light?

This is important if you want to have peace of mind. The longer the warranty is, the better. This means that if it becomes defective, in accordance with the terms and conditions from the manufacturer, they can have it repaired or replaced.

Wrap Up

The best grow light bulb is a must-have when growing marijuana in an indoor environment. The plants will be deprived of the natural sunlight that the sun can provide, which is why there should be a bulb that can supplement such. Not all bulbs, however, are created the same. Pay attention to the products that have been discussed above to choose the right bulb for your grow room.

Horticulture Lighting Group devised the word “Quantum Board”, and this concept spreads the diodes on a board in LED grow lights manufacturing. With this innovation, the blurple light changes to a form that contains a full spectrum consisting of a higher amount of light which, promotes vegetative growth and flowering in plants under them. Quantum board LED grow light got an overwhelming response from the growers soon after its release in the market due to the splendid yields growers got in cannabis farming.

There is no doubt about their performance of Quantum LED lights since a significant number of growers are convinced of their smart spectrum string that adds too much to the growth and yield of plants compared to the ordinary LED grow lights. HLG is still an authority in the manufacturing of quality Quantum LED grow lights in this industry across the world, and they are consistently working to improve the quality of their quantum board LED grow lights. HLG\’s Research & Development wing is one of the most vigilant and zealous departments in the LED grow lights industry.

The Quantum Grow lights mount on a circuit of several diodes in a series containing average-powered LEDs that make a string. The strings then use a parallel configuration and are made companionable with drivers that contain a high power.

The growers could enjoy more advantages and a few cons if they compare Quantum Board LED grow lights with any other existing lights such as COB or ordinary LED grow lights.

Advantages of Quantum Board Lights

For the time being, only COB lights appear a small competitor for the Quantum Board grow lights. Both Quantum Board and COB lights use the same principle for yielding a full spectrum light, while the characteristic difference is mounting several diodes in close proximately to each other in a smaller and tight space when making COB lights whereas spreading them over a huge area in Quantum Boards. This increases the Quantum Board grow light ability to disperse the light in larger space compared to COB light that throws light in concentrated areas. Moreover, scattering a light source saves the plant surfaces in contracting less heat compared to other lights that keep the growing environment cooler. General advantages are;

#1 Heat Management

Heat management in Quantum Board lights is much easy and simpler. Usually, a board mounts on a thin Aluminum plate that doesn\’t need active cooling, such as installing fans or vents. These Aluminum plates stay cool for longer and are sometimes used as reflectors to increase the spreading area of lights.

#2 Uniform Light Spreading

Quantum Board lights spread light over more area as the surface area of the strings is often 12 inches or more, whereas COB throw lights from a single source that measures hardly 1 inch in diameter. The emitted from the Quantum Board is also uniform in wavelength and spectrum.

#3 More Lumens Per Watt

Quantum Board lights are more efficient. Comparing 50 watts\’ efficiency for getting more lumens per watt shows that Quantum Series produce 180 Lumens whereas, a COB may be limited to 160 Lumens per watt only.

Disadvantages of Quantum Board Lights

There could be disadvantages when comparing with ordinary lights;

• Horticulture Lighting Group has a monopoly over Quantum Board Lights, and they often get out of stock.

• Quantum Board is different to manufacture if you do it yourself.

• You could manage more lights at the price you need to buy a single Quantum Board light. Usually, 3 COB lights make the price of one Quantum Board light.

How to Handle and Care Quantum Board Lights?

Do follow these instructions while handling, clearing, and storing Quantum Board Lights;

• Avoid shocks and jerks, and don\’t drop Quantum board.

• Avoid touching LED resin and bending PCB.
• Avoid storage in a dusty environment.
• Avoid disassembling for the fear of VOC’s leakage.
• Avoid relocating Quantum Board lights when they are working.
• Also, avoid touching the circuit when in operation.

Cleaning Quantum Board

Isopropyl Alcohol is the best agent for cleaning LED modules. Non-recommended cleaners could temper the shape and cause trouble to the circuits. However, if it is necessary to clean using other cleaning agents, be sure that the cleaner doesn\’t dissolve the resin or VOC\’s used while cleaning a module. It is advisable to try other solvents or cleaners on a small scale before cleaning the entire board. Avoid using Freon and Ultrasonic techniques for cleaning your product since they have some impositions by regulations worldwide.

Quantum Boards need anti-static electricity, voltage regulator, and well grounding for smooth and stabilized function. Wearing shockproof gloves is also mandatory while handling Quantum Boards.

Why Choose LED Grow Lights?

There are many types of grow lights, but LED is the preferred choice for many people. To be specific, this post talks about 1,000W grow lights with LEDs. They provide higher intensity while being energy-efficient. LED is also known to be long-lasting, unlike others that will quickly ask for a replacement.

How Far Should You Position 1000W Grow Lights from the Plant?

One thing that should not be ignored when it comes to the installation of LED grow lights would be its distance from the plant. If it is too near, it can lead to a variety of problems, one of the most serious would be light bleaching. This will limit the growth of the plant, doing more harm than good.
Although LEDs do not generate as much heat as the other types of grow lights, such as HIDs, this does not mean that you can position it too close to the plant. Ideally, it should be 26 to 42 inches away from the top part of the plant.

How to Take Care of Your LED Grow Lights?

Even if you have the best grow lights, you still need to pay attention to proper care and maintenance, which will be vital in maximizing its performance and prolonging its lifespan. Here are some of the most important things to keep in mind:

• Use a glass cleaner to keep it in perfect condition. Before doing this, however, make sure that the light is turned off and unplugged.
• Make it a habit to wipe the lights or dust it off. When dust accumulates on the surface, the intensity of the light emitted can be affected.
• The right position and location of the grow lights will also be a critical concern. Place it in a room where there is not too much moisture.
• Make sure that the lights are properly connected. Pay attention to all the wirings and provide the right electrical requirements.

How to Choose the Best 1,000W LED Grow Light?

As you try to narrow down your list of possibilities, here are some of the most important factors that you need to take into consideration:

• Energy-Efficiency: This will be determined by the wattage of the light that you will choose. The lower the wattage, the lower is the amount of energy that it consumes. A light with low wattage is ideal for large indoor gardens as it can lead to huge long-term savings.
• Color: If you think that the color of the LED light is just all about the looks, you have to think again. It actually serves a deeper purpose. The color of the light dictates the wavelength that it produces, measured in nanometers. This defines the spectrum of the light. During the vegetative phase, blue light is more beneficial. Meanwhile, red light is needed during the flowering stage.
• Coverage: This is another important consideration, especially for large indoor gardens. You need to make sure that the light generated can cover the entire area. Otherwise, when some plants are not reached, they won’t be able to maximize the benefits of having LED grow lights.
• Cooling System: LED grow lights can be prone to overheating especially when used for an extended period. This makes it important to have cooling fans, providing ventilation that is necessary to prevent the production of too much heat. This prolongs the useful life of the light while also ensuring the health of the plant.

Conclusion

In sum, the best 1000w LED grow light is an indoor gardener’s best friend! It mimics the energy of the sun in an enclosed environment, providing an assurance that your plants will be healthy. Nonetheless, not all lights are the same, so better limit your choices to the five products that we have briefly discussed in this guide.

Cannabis is like humans – it has different needs in the different stages of growth. For instance, while a light is an essential element for growing weed in a grow room, it does not mean that it needs the same type and amount of light from the time it is planted up to the point that it will be harvested.

At different phases, the light needs will differ. Are you looking for the best light for flowering? Let me start by saying that the light that the cannabis needs at such stage is different from what it needs when it is vegetating.

That being said, if you want to find the best light that could trigger the growth of healthy flowers that will positively impact yield, read on and learn from the insights we will be sharing below.

Best T5 Bulbs for Flowering

Lighting Needs of Marijuana During the Flowering Stage

Now that we have briefly discussed some of the models that are worth taking into account, let us have a look at the lighting requirements of marijuana once it reaches the flowering phase.
According to experts in cannabis cultivation, the best light spectrum for flowering of marijuana is red, which explains the products that we have listed above.
More than the spectrum of the light that you are using, the lighting duration is also important. If the light used to be turned on about 18 hours during the vegetative phase, when the plant reaches the flowering stage, you need the light only for 12 hours a day. After about two weeks of having a cycle of 12 hours on and 12 hours off, the buds will start appearing on the marijuana.
The light intensity is also important, which will be all about the power of the lights that you will be using. On average, you should use a 40-watt light for every square foot.

Care for Marijuana During the Flowering Stage

While it is indeed helpful to have the best light for flowering, this is not enough to take care of your plant during such stage. With this, here are other important things that you should do to increase the likelihood of having healthy flowers:

• Watch out for any signs of dead leaves and branches. If you can see any, remove them as soon as possible. This will also prevent the problem from spreading to the healthy parts of the plant. However, if there seems to be no problem, do not cut it.
• The humidity level should be at around 50%. It is important to pay attention to humidity to prevent the presence of mold. Mold will form when the humidity is too high since the plant will absorb the excess moisture.
• Installing a carbon-filtered airflow system will be beneficial for the grow room. This will maintain proper air circulation in the grow room, which is also important when it comes to the prevention of odor.
• Introduce the right nutrients at the right time. Within the fourth to sixth week of flowering, the weed will benefit from being fed with potassium and phosphor. They will support flowering. Nonetheless, make sure that you avoid overfeeding as this could cause stress to the plant.
• If you have a hydroponic system, the management of the pH level will be critical for the health of the plant. Even in the soil, pH has a big role to play. The wrong pH level can cause curled leaves. For marijuana grown in soil, the right pH level at this point should be 6.0 to 7.0. On the other hand, with hydroponics, the pH level should be from 5.5 to 6.5. There are portable pH testing kits that can be used.

Wrap Up

The best light for flowering is indeed an important component of your grow room setup. The plant needs more than enough red spectrum to trigger the growth of healthy flowers. Without the right light, the external environment will fail to provide what the marijuana needs to be able to survive in an enclosed setting.

The vegetative stage is crucial for the growth of marijuana because it determines how healthy and robust it will be once it enters the flowering stage. This is the point when the structural integrity is built, which is why it is important to provide an external environment that will be conducive for its growth. While there are several requirements, one of the most important would be the best light for vegetative growth.
It is important to have the right lighting because it is considered as the driving force for the growth of cannabis. Without the right light, it won’t make it to the next stage. With the abundance of the options that are available, which one should you choose? Be a responsible buyer and read the rest of this guide and we will help you make the right decision.

The coverage area of this LED will reach the largest area when you install it properly. It can cover 3’x3’ vegetative coverage at 20” and 2.5’x2.5’ flowering coverage at 16” height.

What is the Vegetative Stage?

It is critical to have an understanding of the vegetative stage of marijuana to know how important it is to have the right light for the correct external environment.
The vegetative stage is the point in the life of the plant after germination and before flowering. This is when the plant grows its foliage and its root structure. This is also when it becomes stronger, which is in preparation for the flowering phase.
The length of the vegetative stage can depend on the cannabis that you are growing. It could be one week. It could be six months. In most cases, however, especially if the marijuana is grown indoors, it will last for four to eight weeks. It is important that you stay patient throughout and make sure to provide tender loving care to ensure the healthy growth of the plant.

Light Requirements of Marijuana During the Vegetative Stage

More light is equal to more growth – this is perhaps the most important thing that you have to remember when it comes to the lighting needs of the marijuana when it is vegetating.
Take note that the plants should be slowly introduced to light. If it is too sudden, this could cause stress to the plant. During the seedling or clone phase of the plant, it receives minimal light, which makes it important to take things slowly so as not to cause shock.
To be safe, you should position the lighting system at a height of about three to four feet during the initial phase of vegetation. You can move the lights closer as days or weeks pass by. After each day, move the light about three inches lower.

High-Intensity Discharge Grow Lights

There are two types of lights that fall directly under this category – metal halide and high-pressure sodium. HID lights used to be the norm, but with the introduction of their more modern counterparts, it is losing its appeal to some marijuana cultivators.
It produces light with enough intensity to penetrate the plant and to encourage the development of a robust canopy. The light dispersion, however, can be a significant problem. The light is directed only to a single point. For some growers, they solve this problem by using a reflector wing or hood.

Light Emitting Diodes Grow Lights

A lot of the modern lights used for the vegetative growth of marijuana fall under this category. They are great because of their energy-efficiency. The latter is also the reason why it is considered by many to be an eco-friendly option. It also has an extended lifespan.
If you are going to use LED light, it is important that you choose one that comes with a higher blue spectrum compared to red spectrum. This is basically because the blue light is the one that influences the vegetation while the red light is the one that is responsible for flowering.

Compact Fluorescent Light Grow Lights

A CFL grow lamp is not as intense when compared to the other grow lamps. With this, it would be safe to have it positioned about one inch away from the top of the cannabis. The further the CFL is away from the plant, the more light it loses. Therefore, if you position it about five to six inches away, it will already be useless.
When using CFL, look for one that has 6500k, which means that it is giving off a light that is comparable to daylight. 2700k CFLs, or those that give off soft white light, on the other hand, are the ones that are recommended during the flowering stage of the plant.

T5 Fluorescent

This is considered one of the latest innovations when it comes to marijuana lighting during the vegetative phase. It is a replacement to the obsolete T8 and T12 fluorescent lights. It has high output and excellent dispersion, which are two of its best assets. They are usually two to four feet in length, which will be great for a big grow room.
The low heat output of T5s is also one thing that makes it great for the vegetative phase. This means that it won’t lead to plant stress.

Maintaining Marijuana During the Vegetative Stage

The use of the best light for vegetative growth is just one piece of the puzzle. Light is important, but this is not the sole factor that prepares the plant for the flowering stage. That being said, this section will provide you with a quick look at other important things that you need to do during this stage.

• It is important to feed the plant with the nutrients that are essential for growth. To be specific, they will need nitrogen and potassium. Go easy on the fertilizer as feeding the cannabis with too much can add stress to the plant.
• The right temperature is also a paramount concern. There are some marijuana strains that can grow in an indoor environment with a temperature of 15 degrees Celsius. However, in the case of most strains, the ideal temperature range would be from 21 to 30 degrees Celsius.
• Meanwhile, for the humidity, you need to maintain it at 45 to 65%. There should also be fresh air moving. With proper ventilation, it becomes easier to maintain the right level of the humidity for the grow room.
• Water is also critical but give it to the plant when only when it is needed. One of the obvious indications would be when the medium appears dry or when the leaves start to wilt or droop. Too much water, however, can lead to the death of the plant.
• Training techniques should also be given attention during the vegetative phase. Pinching is necessary to trigger the growth of branches. Super cropping is also necessary to be able to dictate the shape of the plant as it grows larger.

Wrap Up

Choosing the best light for vegetative growth is a task that requires careful thought. You can choose HID, LED, or CFL, but it does not mean that all of them are great picks. You need to consider a variety of factors, such as spectrum and wattage to be sure that it will not ruin the vegetative phase and that it will prepare the marijuana to be stronger as it enters the flowering stage.

I Welcome Cannabis Growers to the Best Kelvin for Flowering Growth 2022
I understand how hard it becomes for cannabis growers when they need to select the best light out of many dozens of products that are currently available on the marketplace. Every manufacturer claims the supremacy of their product. But it is real-time testing that evaluates which one to trust. I also kept myself busy with the trialing of a few dozen lights in my grow room where I often test the performance of different cannabis and vegetable varieties.

This time, I had several advantages for having a few short stature cannabis strains in the flowering stage that took me two weeks to evaluate the performance of several lights and determine which Kelvin scale is best during that stage. Besides some difficulties that every grower faces, I am glad to share which lights contributed the most to achieving higher productions. Trust me since I evaluated light performance under the guidance of many scientific articles that could help you find the right lights match for growing cannabis.

Grow Lights Kelvin

Since cannabis growers are well informed that Kelvin is the warmth of light. The higher the Kelvin scale, the more cool light is. Grow lights Kelvin which, is above 5000 is the product of blue light. In other words, the bluer light will possess more kelvins. Similarly, when the Kelvin scale drops below 5000, the warmness starts increasing. It is the product of red light. The redder a light is, the greater is the warmness. Besides, the Kelvin scale could drop eventually, from 5000 to below 2000 kelvin.

That\’s the reason the cannabis growers need lights having a color temperature between 2700K to 3000K for flowering their plants, and it continues to perform well up to 3500K. It never means that role of blue wavelength finishes while flowering as it keeps on complementing plants\’ growth processes such as food assimilation, stem elongation, adding more nodes to the stem, and splitting up branches to form denser canopies. Therefore, a combined effect of cool and warm light could better promote flowering and subsequent growth of cannabis plants in any sort of indoor growing.

Depending on the types and make, the grow lights may scale between 2000K to 7000K. Don’t mix Grow Light Kelvin and Lumens at all since Lumens are entirely a different thing. Lumens only deal with the brightness of a light and the majority of plants need different Lumens throughout their lifecycle. For instance, Cannabis plants demand 10000 Lumens per square foot of grow space. But, it could help cannabis plants grow successfully, even if they drop to 2500.

Otherwise, the optimum growth could observe Lumens between 7500-10000 per square foot, average being 5000, and minimum level that Cannabis plants could continue the entire growth process are 2500-3000 Lumens per square foot. Usually, every watt consumed for running an LED light could produce between 80-90 Lumens. But, it entirely depends on the performance and efficacy of any light. Some LED grow lights are even 40% efficient. Besides, the best lights are up to 60% efficient. Additionally, the LED grow lights that use 3W, or 5W chips are highly efficient.

HPS Kelvin

High-pressure sodium bulbs produce red light, and the cannabis growers are fully aware that they are associated with low Kelvin scales that vary between 2100 to 2700K. It is the scale that suits well when the cannabis plants move into the flowering stage. The growers can compare HPS light with the sunset in autumn, and this is the time when cannabis steps into maturity if it grows in the outdoors. The cannabis plants maybe wanting redder than the blue to promote a high floral index at this stage. Any grow light that provides a dimming option could induce flowering in cannabis plants by proving them with a more red and less blue spectrum during the flowering stage.

Moreover, combining two different kelvin scales from light different sources could also improve flowering in cannabis plants. It\’s always necessary to note the flowering starts with age, and there is a huge variation between different cannabis strains when we talk about flowering. You can\’t induce flowering in cannabis plants before time because it could stress plants\’ growth resulting in lower yields. However, the cannabis plants growing in the unattended environment could behave differently depending on the climatic condition. They could either produce early flowering or delay, as far as indoor growing is concerned, the primitive focus is to get higher yield along with superior taste and aroma. So, let the cannabis strains grow to their set potential to get the desired results for higher THCs.

Best Kelvin Lights for Flowering Growth Reviews

#1 MARS HYDRO TS 1000W Led Grow Light (Premium Brand)

I found it an exceptional performing light and got nearly 500 micromoles per square meter per second by hanging them 18 inches above the cannabis canopy. Its coverage could extend up to 9 square feet with a consistent Kelvin scale of about 2700 micromoles per square foot per second. The dimmable options also allow cannabis growers to regulate light needs during different growth processes. Overall, 342 LEDs burn about 150 Watts of energy while running at a full capacity. Moreover, you could check the temperature and humidity in the grow room with a free and precise Thermometer and Hygrometer that come free with the package. It can potentially give you a harvest that reaches up to 1.5 gram per watt that it draws from the power source. Besides the flowering stage, it could complement the light need for seedlings and vegetative growth as well. here is a link to see customers’ ratings and reviews;

#2 King Plus 1000w LED Grow Light (Runner Up)

Runner up in the yield competition and economical. Switching over to the bloom modes gives cannabis plants an additional boost for inducing flowering and getting quality buds. Though it\’s helpful throughout the cropping cycle of cannabis plants, its response during the flowering stage was exceptional. King Plus Incorporate Bloom Kelvin with white light, and there is no harm in switching to this mode for increased flowering. The temperature of the cannabis grow room also remains ideal in the ranges between 50 to 60°F, and there remains a little need to dehumidify grow room. They use 10W chips instead of 3W or 5W. That\’s why it could effectively replace a 600W High-Pressure Sodium light. Moreover, it runs cool and saves energy, and could buy one unit under $110 from any marketplace. The growers could check detailed specs through this link;

#3 SPIDER FARMER SF-4000 LED Grow Light (Economical Choice)

SF-4000 presents an extended flowering output to a 25 square feet area and suits the commercial cannabis growing facilities. Its bright light and Kelvin scale ranges between 3000 to 5000K which, means it could add more to the flowering induction than vegetative growth. Moreover, SPIDER FARMER uses Samsung Diode series-LM301B that considerably enhances both canopy light penetration and active footprint. Along with an enhanced footprint, it could effectively deliver up to 2.7 micromoles per square meter per second, much higher than any other light of the same capacity. Additionally, it\’s a power-efficient light that could run between 350-450 Watts Samsung LM301B diodes, high Energy Efficiency with 2.7 micromoles per square meter per second that optimize yield. The 3000 Kelvin scale diodes specially design to boost flowering and turn most of the vegetative growth into productive buds. Commercial cannabis growers would love it.

#4 Advanced Platinum Series P300 300w 12-band LED Grow Light

P300 is essentially more powerful than the majority of the LED grow lights of the same capacity and their coverage is also way bigger than traditional lights that intensify by integrating 90-degree focusing lenses. The footprint extends to 16 square feet while hanging them 18 inches above the cannabis plant\’s canopy. The Kelvin scales lies between 2700-3200K that greatly impacts flowering at the later stages of growth. Moreover, there is minimum lights waste for the technology adopted in the making of P300. Power consumption varies between 93W for the vegetative cycle and 180W for flowering. Moreover, vegetative and bloom switches allow the cannabis growers to select the desired switch according to the changing state of the plants. One advantage is a prolonged warranty. It is a bit pricy But, it\’s hard to find its close match.

Here is a link to see its performance and detailed specs on Amazon;

#5 HLG 550 V2 Rspec 500w 120 Volt- Horticulture Lighting Group Quantum Board LED Grow Light

Another super performing US brand But, a costly option that could deliver 3000 Kelvin you\’re your cannabis plants need at the flowering stage.

The light cycle for cannabis seedlings is a pretty debatable topic, and several researchers present their personnel point of view based on their findings. But, the actual growers are of different opinion when it comes to the seedling light schedule.

Generally, Cannabis plants grow in three ways: The first method deals with germinating seed indoors and allowing the Cannabis plants to complete the entire lifecycle within a controlled environment. In such an environment, the Light schedule for seedlings varies in different cannabis strains across the processes that plants complete within such an environment.

The second methods deal with completing the first two processes of the cannabis plant cycle, like seed germination and the preliminary seedling stage, indoors and then transplanting them to the garden beds. Here the transplanted cannabis seedling light cycle is at the mercy of the sun.

The growers can’t delay or shorten the seedling stage light cycle unless the cloud cover interrupts to shorten a day’s length, or a bright sunny day could add a few more minutes in marijuana seedling light. The growers don’t have control over the light cycle for seedlings in the third method.

It involves allowing the cannabis plants to complete all growing stages in the outer garden beds. However, the growers could regulate the light schedule for weed seedlings if they grow them in small nursery trays instead of seeding them directly to the garden beds.

Besides, updating cannabis growers about light schedules during variable growth stages such as seedlings, initial vegetative, Secondary vegetative, and flowering stages, etc., We will also highlight some ideal grow lights which are essential for the seedlings. But perform exceptionally well for the higher production that cannabis growers often dream of.

How Important is Light for Cannabis Seedlings?

While growing cannabis plants in a natural environment, it utilizes water and CO2 in the presence of sunlight and converts them into oxygen and glucose. Otherwise said that it is the process that converts light energy into chemical energy that cannabis plants utilize for the growth and development processes.

Several physiological processes also take place only in the presence of light. When we grow Cannabis indoors, we have control over all factors But, the light is the limiting factor that is supplemented with the help of an artificial source. As the efficacy of any light determines the THC level in cannabis plants, it becomes necessary to provide cannabis plants with the light source that excels.

We see several types of LED Grow lights on the marketplace for this purpose. We would better discuss them later. Let’s first determine: why the growth of seedlings, their development, and care are more important than all other growth stages of cannabis plants?

The cannabis seed contains both the “code” and “coat”. A seed coat encloses the food that seedlings depend on for the initial few days after germination. A code contains the inherited characteristics: that how cannabis plant would look like, it’s degree days to mature, flowering pattern, and THC level. etc.

It is important to note that only female plants’ seed reaches the buds formation stage. Male plants are not viable. But, they could achieve a similar height and shape since they belong to the same genetic code. Once the sprouts emerge from the seed and utilize food stored in the seed coat, it becomes very prevalent for the seedlings to assimilate food for their survival. This food synthesis is dependent on a quality light that helps them fix their food, instantly.

At his stage, seedlings need to be exposed to a bright source of light for prolonged hours. This duration may not be available to every grower working on cannabis seedlings, so the growers expose seedlings to the artificial lights in their growing environment. Seedlings are the foundation stone for any crop that determines their success in the rest of the stages till maturity, provided that the other conditions remain ideal in the process.

Light Schedule for Seedlings

Now, I hope that the role of artificial lighting or light supplementation is pretty much clear during the seedlings stage of cannabis growth. Seedlings have to switch from the stored food mode to self-assimilation. These seedlings would not need only the prolonged lighting hours But, the special care that, typically, a small plant needs from day one. Be sure the cannabis seedlings’ other requirements are also small due to their size.

Cannabis seedlings could survive only with little irrigation, a smaller amount of fertilizers, and other inputs. But it would want a continuous source of light to assemble their food. Coming back to seedlings’ light schedule, cannabis seedlings grow successfully, where they receive at least 14 hours of sunlight in their natural habitat.

Since indoor cannabis growers install LED grow lights because the light is the only limiting factor there. They expose cannabis seedlings for 18 hours at least and keep lights off for the next 6 hours. If any indoor grow room doesn’t receive even the ray of outdoor light during the day, it is good to keep the lights switch off during the night.

This practice could provide your cannabis plants to complete darkness for the next 6 hours after exposing them to extended hours. Seedlings or fully-developed plant uses stored energy during the night and keep on translocation energy to different parts of the plants at night.

Some growers and researchers are convinced about exposing cannabis seedlings to even longer hours. It could be 20/4 or 24/0 before the initial vegetative stage arrives. After that, they continue selecting the 18/6 schedule up to the late vegetative stage. A distance of an artificial light source is also important.

Cannabis seedlings are delicate like every other plant while keeping lights closer to the plants’ canopy could burn them. It is necessary to maintain a fair distance of the light from the seedlings. Usually, it varies between 24-36 inches which, depends on the intensity and wavelengths of LED grow lights. When cannabis plants advance to late vegetative and flowering stages, light scheduling changes and more intensive lights help flowering and budding stages.

How many hours of light for seedlings?

It is suggested to expose seedlings for 18 hours a day for the initial 14-21 days. You could continue the same routine till the start of flowering.

How much light do cannabis seedlings need?

Cannabis plants don’t like high-intensity light during the seedlings stage as it causes to burn out foliage and rapid drying occurs that may dislodge plant seedlings. Usually, placing LED grow lights 24 to 36 inches above the canopy is more beneficial for their rapid growth.

However, it entirely depends on the wattage of any light that it uses. After the seedlings develop an intensive root system, you could move to grow lights closer and reduce the lighting hours. Anyways, switching LED lights on for 18 hours is the best practice for seedlings.

Initially, it looks more important to me to convey to our readers what is “White” lights in the real sense and how does it look white. Sun is white, and it emits a combination of visible light containing a rainbow of colors that appear white to us. White can’t be called a spectral color. But, the output of interacting several light spectrums together. Similarly, any White LED grow light can’t replace sunlight but somehow resembles sunlight in brightness and color spectrum due to artificial arrangements.

Human eye-cones could differentiate between three prominent members of rainbow colors., i.e., Green, red, and blue. If a combination of red, green, and blue represent an equal strength, it will form a light that appears white to the human eye. There are numerous diverse means that the human distinguishes white light from the mixture of the different cog of colors. Yellow light stimulates two eye cones that are red and green. Hence, a mix of green and red also appears white to the human eye. Moreover, several other combinations also appear white to the human eye, even if the spectrum of light is not complete.

LED Diodes

The Diodes used in LED lights manufacturing are unable to produce white light directly as an individual light only designs to produce one color. The recent advances in LED manufacturing use blue LED coated with Phosphor that emits a yellow light but, it appears white to the human eyes due to highly induced Color Rendition Index. Plant advantageously absorb more amount of red and blue lights. One of the biggest advantages that come with white LEDs is that they keep the growing environment and surfaces of the plants cool. Some clients even questions are white led lights good for growing or will white led grow plants? The answer to both questions is YES.

There is another truth that white light LED grow light helps plant to complete the process of photosynthesis more effectively and speedily, for it contains the biggest portion of red and blue wavelengths that plants need for this process.

Several manufacturers claim that their LEDs are best producing white lights. But, the growers mostly rely on the real users and trust their reviews for the performance of any sorts of LED grow lights. Here is the list and reviews of the Top 5 Best white led grow based on the satisfaction level of growers;
