Everything You Need to Know About Grow Lights
Growing a marijuana plant indoors means you will need to provide it with all the elements it is supposed to get outdoors – but they need to be artificially created. On paper, this sounds rather complex but when you actually set out to do it, it’s a rather simple task. You need to get hold of all the right equipment – such as grow lights, ventilation kits, grow tents, etc. and you’re all set to grow your own weed. Grow lights form one of the core parts of this process of growing weed indoors – as they offer a number of benefits to the plants. Here’s a look at why you need grow lights:
What is the importance of grow lights
Plants need light for a lot of their processes – first off, they require lights to make sure that they are getting proper growth as plants tend to grow in the direction of the light source. To add to that, sunlight helps trigger two important processes – the production of chlorophyll which is an important pigment, as well as the process of photosynthesis, using which the plants make ‘food’ which gives them the energy. Their intake of oxygen and carbon dioxide is also dependent upon the light. Lastly, lighting also helps the plants force-enter the bloom phase.
There are a number of grow lights that you can find in the markets but LED grow lights such as the King Plus 3000W hold a special importance. Let us now look at what makes LED lights better than regular grow lights:
Why are LED Grow Lights Best for Growing Weed?
LED grow lights are simply the best for growing marijuana indoors because of multiple reasons. The most important of these reasons that every grower must know and understand is the fact that LED grow lights draw the least amount of power while providing the highest amount of lighting – be it in terms of lumens or wattage! Furthermore, LED grow lights also have a much higher lifespan compared to older grow lights such as Metal Halides, HPS Grow Lights or CFLs. To add to that, LED grow lights can function even when some components get damaged as they are not interlined to each other – and lastly, they are easy to dispose of as they do not carry any harmful chemicals in them.
King Plus: Is it a credible brand?
King Plus is a brand which is known for making big and bright LED lights and this is just another of these products from them. The company (KingLED) has been into this business for over 8 years now and is one of the most seasoned and experienced names in the markets. The brand is based out of Shenzhen in China and offers the growers with some of the best quality grow lights – especially for those with particularly large needs such as this 3000W LED grow light here. In addition to manufacturing LED grow lights, KingLED also manufactures lighting equipment specially developed for aquariums. They also put special emphasis on research and development of their products and have a good customer care support system for their buyers worldwide. All in all the brand has a positive rating and a decent credibility in the markets.
King Plus 3000W LED Grow Light Review (2022) – is it worth buying?
Here’s a detailed review of the King Plus 300W LED grow light where we have tried to cover as many aspects of this grow light as possible!
Design and Durability
Measuring in at 26” X 15” X 6”, this is one of the largest grow lights that you can find for your grow tents or grow rooms. At 3000W, this size and shape is almost expected. The light weighs 16.2 lbs and can be easily hung in large grow tents as they are equipped to handle weights of close to 150-200 lbs with ease. The main panel features a single compartment behind a glass screen which has 300 LEDs built in it.
On all four sides of this grow light are vents for heat to escape. On the right side, you’d find two switches – marked VEG and BLOOM, to be turned on during those phases of growth. Between the two switches is the port where the main power cord goes in. There’s no provision for daisy chaining in this LED grow light. On the back side of the KingLED 3000W LED Grow Light, you would find three slots for the fans so that the heat can escape from there, along with four hoops using which this grow light can be hung properly. All in all a decent design and a durable grow light.
Spectrum and Light Details
This is a full spectrum LED grow light, which helps the growers ensure that their plants are getting as close to natural lighting as possible. There’s a 12-band full spectrum of lights involved in this process, which ranges from 380 nm to 780 nm – there’s also IR lighting and UV lights which are involved, which is great for the growers. Each of the diode here comes with an additional optical lens cover which is great for the overall lighting experience.
There are 300 LEDs here, each operating at 10W giving you a total output of 3000W. The LED lights here are focused at 90°&120° mixed angles which gives the plants a good benefit of direct lighting. Most importantly, there are two different switches of VEG and BLOOM mode which ensure different kinds of lighting can be provided to these plants during different phases of their growth. During the VEG phase plants need a higher shade of blue while during the BLOOM stage the reds are more important.
Brand Value and Credibility
As we’ve discussed above, KingLED is a good name in the markets and growers who use this grow light have left behind largely positive feedback about it. Most growers are happy with the company and its services. King LED has been making lighting equipment for over 8 years now and they’ve gained quite a specialization in this field by now and are a brand trusted by most experts. The brand value and credibility is pretty good and it fetches a decent resale value as well.
Here’s the best part about the King Plus 3000W LED Grow Light – the coverage that you get. Most of the times when people are looking for large grow lights they’re not sure what they’ll get. There’s plenty of small and mid sized grow lights available between 300W to 1200W – and even upto 2000W there’s a lot of options. But once you go beyond that you’re on uncharted territory and this is just the perfect option. This 3000W LED grow light covers an area of an impressive 7.8’ x 8’ which is pretty large and can cover up an 8×8 grow tent with ease during the vegetative phase. The area shrinks down a little during the bloom phase where the flowers begin to emerge as you need to move it closer to the plants – then it becomes 6.5’ x 6’ which is still pretty wide for a single LED light panel!
Another front where this grow light delivers really well. When you say your LED grow light is a 3000W light, it does not mean that it consumes 3000W of power too. This basically means that the light output you’re getting can replace a traditional 3000W lighting solution. When you look at the actual consumption and the amount of power it draws from the power socket, it is about 1/5th of the total output – the power draw is approximately 610W when you switch on the VEG as well as the BLOOM switches and it goes down significantly when you switch either of the two off. There might be a variance of about 5-10% than the figure quoted by the manufacturer but it doesn’t usually go beyond that.
When you look at the PAR value and the results that you get from PAR testing, you get very impressive numbers. The results are 1582 uMols when this grow light is hung from a height of 18” and 923 uMols when hung from a height of 24”. These numbers are impressive but also this is something that you expect of it because this is a 3000W LED grow light which is extremely bright and hence a good PAR score!
Cooling is another important aspect of any grow light, but is essential to look at when you’re looking at anything upwards of 1200W because this is when it starts to get REALLY hot. This grow light, thankfully, has an excellent cooling system. There’s a combination of multiple fans working on the back side which make sure that the heat is dissipated pretty well. Any heat that remains trapped inside the system can damage not only your plants but the grow light too! However thanks to the strong cooling system made with the fans and the heat vents, you get a great grow light here which ensures the heat does not stay in the body. However some growers have complained that the fans do get a noisy.
Warranty, Cost, and Delivery
The warranty that you get with the King Plus 3000W LED Grow Light is that of an impressive 3 years, which is among the best in the industry. There are only a handful of companies which offer more than this and this is a really good statistic. In addition to the three year warranty that the King Plus 3000W LED grow light gives you, there’s also a 30-day return period where you get your full money back if you are unhappy with the way this grow light is functioning. This basically shows the amount of trust that the company puts on their product! It is delivered by Amazon and is a fast delivery which ensures that your product reaches you in a good condition. Returns are also easy, thanks to Amazon.

All in all this is an ideal grow light for tents between 6×6 to 8×8 and can be used in combination with smaller grow lights for tents as big as 10×10 or 12×12.
3. Is it legal to buy this LED grow light?
Yes, buying LED lights is a totally legal activity and would not draw any legal trouble but you need to be careful about what you are growing. Certain plants are illegal to grow, such as marijuana – and every country and state might have different laws about it. So you need to check with your local law enforcement if growing weed is legal in your area, and if it is legal, how much weed can you grow.
