Growing weed isn’t as complicated as you may believe, but you will have to know a lot of factors. I know this from my own experience, so I know how to help you perfectly. Although there are several factors to remember, things to know and several additional elements, I will stay focused on one which is so simple, yet so important. Yes, this article is related to the LED grow lights. They do look like simple elements, but they are something which makes a true difference.
Why using LED Grow Lights is Crucial for Having a Great Yield
Of course, all of us know that using some kind of lighting when it comes to the weed growing is a must. There are two main alternatives here. I tried both of them, so I can tell you good sides of each one. Also, I will mention the downsides of both.
Originally, I used fluorescent and then move to HID lighting. Yes, these methods are very cheap, but they are a nightmare. I had to invest in special equipment which would hold the lighting in perfect position and I needed tons of fans just to keep temperature average and suitable so my weed doesn’t ‘’disappear’’. At the end of a day, this isn’t so great. Yes, you will save some amount of money in first place, but you will spend much more on cooling and hangings equipment. Grow light bulbs will be turned on all the time, which also means that they must be replaced frequently, which isn’t something you want to do. In one occasion, I had to replace more than 2 bulbs each day. The next main issue is when a bulb is damaged overnight, so weed doesn’t get light more than a few hours. And yes, I didn’t forget about ballasts, which are mandatory in this case scenario.
In simple words, LED grow lights eliminate all of that. First of all, the LED will last up to 50.000 working hours, so there is no reason to replace it sooner. This is the smallest advantage of the LEDs. They also consume much less electricity than any other type of lighting. Then we have the heat advantage. Keep in mind that LEDs will generate far less heat than any other lighting, therefore additional fans may be irrelevant. Furthermore, some models come with built-in fans so they will always keep the temperature at perfect level. The last, but not least, LED lights don’t require the use of ballasts, making them even more suitable for beginners.
In a nutshell, LED grow lights are mandatory and the ultimate alternative for all growers. They are sophisticated, eco-friendly, safer and a wiser choice compared to traditional HID lighting. All of this should help you understand why this lighting is so popular nowadays and why it is far better than any other alternative. It is actually difficult to understand people who choose traditional lighting.
Factors to Consider for Purchasing LED Lights for Growing Weed
I explained why LED lights for growing weed are so much better than any other alternative, but now is the time to help you understand how you should choose them. Marijuana grow lights come in different sizes, with different features, and with different specifications, therefore there is a lot of factors you should know before purchasing a specific model.
Overall, it is essential to match your needs with the capabilities LED lights will offer. Only then I was able to maximize the yields and to make the entire procedure simpler and easier at the same time. So, below I will guide you through several factors which must be taken into consideration when looking for the LED grow lights for weed.
Yes, you will want to consider wattage of the LEDs, but there is one important fact to know. An LED with a wattage of 300W can replace HID lighting bulb of 300W perfectly. But, LED has a much lower voltage, so it may be labeled with 140V, but there won’t be any issues. In general, the higher the wattage, the better.
- Full-spectrum LED
If you are planning to use LED lighting through the entire cycle of marijuana growing, you will need a full-spectrum model. Not all units are like that, so always check the labeling and the user manual. I personally believe that they are the best choice. Of course, they are slightly more expensive, but they are the best.
- Area you need to be covered
The area you need to cover will determine the need for LED lighting. Always make sure there is plenty of light at all times and make sure you used the maximum allowed power of the LEDs. Attaching one next to the other makes all of this easier and simpler.
- Angle of the LED lighting
Each growing weed for dummies guide will mention the fact angle of LED is crucial. A higher angle capability allows you to cover more space, while a lower angle offers more direct lighting, even makes it possible to illuminate one plant only. I like those models with medium angle capabilities. They are the best and easiest to use.
Yes, the budget is important when comes to LED lighting for weed. Models with higher angle capabilities and built-in fans will cost more. Those with higher wattage and voltage will cost more as well. So, try to find a balance. There is no point in looking for extra-big and powerful LEDs if you have a small growing area to cover.
On average LEDs can last up to 50.000 hours, but this cannot be generalized Some models can last up to 100.000 hours, so they are a much better choice for those who are planning to use them for a longer period of time. Of course, they are more durable. I believe that if there is no need to replace the LED lights in the near future with bigger ones, you can always choose those with the longest lifespan.
I personally believe that there is no such thing as the main factor to consider. All of them are important in their own way, so the key element here is to know that they should be well-balanced. It means that you should pay attention to your requirements and choose a LED light accordingly. If you get better performances than you need, even better. Just avoid getting LEDs which cannot meet the requirements of your plants!

So, what must be mentioned here? The LEDs are developed on the platinum technology, so they provide light which is 3 times brighter than usual. Then we have the fans which are 4 times more efficient, yet quieter than other models may feature. A 5-year warranty is available as well.
Cover area is 6×4 feet and a height of 18 inches made it suitable when there is not enough of space for other models to use.

5. California Lightworks Solarstorm 440-watt LED with UVB
Here is one of the LED grow lights which is solely developed for professionals and experts. I have been using it for quite some time and I must say it is an excellent product. The main advantage is in the emitter diodes. There are 88 of them, 5 Watts each and they offer superb light brightness and quality. But, there are also two UVB light tubes, so the overall lighting is almost 2 times better than similar models have to offer. All of this suggests that this unit is more than just impressive and sophisticated.
The primary optics are the next main advantage here. It is a 90-degree unit which offers superb, or better said glass jewel quality, so there is no need for secondary optics. Paired with the emitter diodes and UVB tubes, the lighting effect is immense, in the lack of a better word. Cover area is 3 x 3 feet, which may sound generic, but there is another advantage here. There is no wasted light, so all the light produced by the LEDs is directed towards the plants, where it should.
This simply isn’t one of the cheap LED grow lights available today, but it is one of the best, that’s why it is on the list. The price will go significantly upper if you choose some of other versions, such as 2, 4 or 8 pack system.
The last, but not least the photosynthetic photon flux or PPF system is impressive no less. It offers better performances when it comes to the light penetration and it has a positive effect on the plants.

If you are wondering about the results, let’s just say that they are the best you can get.
A low heat generation and high-quality LEDs made this unit special and in the best case scenario, more suitable for professionals. I have been using it for some time and I was perfectly satisfied, although a large size means that it isn’t great for smaller areas. Warranty is 3 years which is slightly better than some other units have to offer and the customer support is superb. I actually checked this factor and I must say that I was pleasantly surprised.
A cooling fan is covered with a dust filter, meaning that it doesn’t require maintenance and you can use it in areas where dust is a common issue. Paired with a system which reduced the heat for 50% makes this unit something else. There are no heating issues whatsoever, so I would recommend it to users who live in areas where high temperatures are common. In addition, ventilation is better than on other units, so it offers obvious benefits. Yes, the price is special as well, but this is a professional unit, designed for professionals.

The Roleadro 300w LED Grow Light Galaxyhydro Series Full Spectrum Grow Lamp paired with some of the best grow tents will make your yield a bit better than ever before. So, what’s there to like about this model. I liked the fact it offers IR and UV capabilities. The emitter diodes come in blue and red hues, therefore they offer all the advantages and provide all the essentials to the plants, but there is no wasted spectrum. In a nutshell, this is all you can want.
Lenses here are state of the art. They feature 120 degrees and they are known for boosting the light penetration up to 150%. This has an impressive effect on canopy and allows better productivity. Keep in mind that this unit is reserved for 40 x 40 inches of coverage area. I tried it on slightly bigger areas, but results weren’t ideal. On the other hand, on this cover area, the results were phenomenal. Now, the cooling system. It is all new system which is more efficient, uses less energy makes less noise and offers better results in general. The warranty is 2 years on the entire system.

9. Apollo Horticulture GL60LED Full Spectrum 180W LED Grow Light
Of all, affordable LED lights I was able to test, this one is the most appealing. The thing I liked the most is the quality and the price balance. The unit is well-made and comes with all the elements and features you are going to need. A cover area is 5 square feet which are an advantage if we know that the dimensions are 6 x 12.5 x 12.9 inches. It is also lightweight, with a total weight of 5.4 pounds, so using it is more than just simple.
There are 6 band spectrums here. They start with 430 and reach up to 730nm. Lifespan is 50.000 hours, which isn’t the best, but if we take into consideration the price, it is more than just decent duration. The last thing, I also liked the most is the wattage available. It starts with 75W and reaches 1200W. What this means is that it is possible to combine several units in order to provide the best lighting conditions for the plants. There are no limits here and the success rate is above average.
To summarize the things regarding this model. It is affordable, useful and available in different sizes and with different characteristics. Most the best hydroponic systems I was used were combined with this LED grow light and the end result always was above the average. Although round design makes the things a bit more complicated, the overall effect is still at the highest level possible.
- More than just affordable
- Available in different wattages (75-1200W)

10. VIPARSPECTRA Reflector-Series 900W LED Grow Light
I actually was impressed with the VIPARSPECTRA Reflector-Series 900W and I notice that all LED grow light reviews of this unit are similar or better said positive. The main reason for that is in the technology. Although this isn’t the latest model, it is more sophisticated than usual. As such, it consumes only 412 watts, but it can be compared to units of 1000W power. It is truly an advantage, especially if we know that the overall effect and results haven’t been compromised. All of this means that it saves energy but doesn’t have a negative effect on the results.
The entire LED grow light is designed to maximize the potential. That’s why I noticed that the fans are of the latest generation. They are extremely quiet, yet they are able to cool down the entire unit all the time, eliminating the risk of overheating or causing any other type of damage. The size made it suitable for 4 x 4 feet of cover area, so do not try to use it on larger areas. There will be side effects.
Frequency is between 50 and 60 Hz, while the lifespan of the LEDs is 100.000 hours. Obviously, this is a premium model, so I didn’t expect anything less. In the package you get a 6-feet power cord, hanging kit and a user manual, which is decent, but not ideal. Overall, I noticed that the heat generated is 70% lower than with HID lights, the quality of the LEDs is superb and the overall performance is phenomenal. There are no side effects nor severe drawbacks of the unit. I also believe that value for money is great. Growers who want powerful, sophisticated and relatively affordable LED grow light, should consider this unit.

You should understand that all LED grow lights will be used most of a day, so this advantage will have a huge effect on the energy consumption. Then we have bloom and veg features, which also come with a built-in timer, so light can be turned off at a specific time. I personally prefer the PAR system which maximizes the light penetration for additional 150%. There are several other models with this feature available on the market, and all of them are highly appreciated.
One of many reasons why this isn’t an ordinary LED grow light is the mixture of the capabilities. Combined, they will boost the metabolic processes in the plants, therefore has a positive effect on the yield. The reflector of 90 degrees is just right but isn’t special. What’s special is the remote controller. This is one of rare LED grow lights with the feature in question and it is more than just beneficial. At the same time, it makes the entire job much easier. As I have mentioned earlier, this is a high-quality unit, so the lifespan of the LEDs is long. It is 100.000 hours as a matter of fact.
Dimensions are 2.8 x 15.7 x 15.7 inches, therefore they make this unit suitable for bigger or more demanding purposes. The weight or 20 pounds won’t be an issue.

The massive 1500W system is perfect for all of you who want the best results all the time. I have been using this model for quite some time, and I am more than just satisfied. What’s more, the system uses all-new three-chip LEDs. They are more durable, more efficient and offer better results than older, 2-chip models. Obviously, all of this has a positive effect on the overall effect and the plant ‘’satisfaction’’. This also means that the plants will grow faster. A full spectrum supports blue red and white, alongside IR and UV rays, so it is almost identical to actual sunlight.
Cover area is 6.4 x 6 feet and the light distribution is impressive no less. Now the cooling fan. It is a bit better than other models have to offer. First and foremost, it comes with two fans instead of one, so cooling is straightaway much more effective. Power factor is 97% while the lifespan is 50.000 hours. Then we have a 3-year warranty and 30 days money back guarantee. I must add the excellence and professionalism of the customer support, which truly stands out from the crowd.
I also liked the fact the manufacturer includes some tips regarding the LED light. For example, it should be placed 1-1.2 meters above the plants; it should be turned on 12-14 hours during vegetative phase, 9-12 hours during flowering stage and 7-8 hours during fruiting stage. All of this is more than just helpful for beginners.
- Extremely powerful
- Affordable but not cheap product
- Included tips are more than just helpful
- 150 LEDs are more than just enough
- Lifespan is 50.000 hours

Now, they use less energy than ever before, have a longer lifespan of 50.000 hours and they provide brighter light. All of this means that the overall performance is significantly improved. The second upgrade is related to the fan system. Now, it doesn’t make any sound at all and it is capable of cooling down this unit at all times, even when it is turned on all the time. So far so good.
The fact there is support for IR and UV makes all things even better. I also appreciated the money back guarantee and the fact it comes with all the features and elements which are essential for you to use it straight from the box. Hanging feature is very useful and convenient, but there are better models out there. The next drawbacks I the warranty, which is 12 months only. However, this is an affordable model, so I understand these drawbacks. On the other side of a story, the overall quality is interesting and on a high level, I must add.
Some other points which should be mentioned are a low weight, which maximizes the functionality. Size is decent as well, so a cover area won’t be an issue. Nevertheless, this unit is suitable for beginners or intermediate growers. Still, it offers a bright light and it is a durable unit, so in a nutshell, it can be used as an additional LED grow lights.
