The X 600W Pro is designed for both the vegetative and flowering phases, and this model also has the dimming option as well. Keep in mind that this model, along with most other PhotonTek models are quite sturdy and well built, so you won’t be regretting the extra money you’ll spend on it.

The manufacturers achieve this by providing us with a healthy mix of warm white light, blue light, and some red light as well through it's 1716 LED pieces.
Aside from having a great light spectrum, the SF 7000 also offers several other helpful features such as the easily adjustable height, dimming lights, they have a layer of humidity-proof coating, and they operate at a lower heat than LED grow lights in this category.

This fixture offers anything a grower could ever dream of when it comes to a grow light. Tunable spectrum, Wireless connectivity, patented optics and top quality components make this option one of our personal favorites.
The team behind Scynce LED keeps coming up with innovative products to fit the highest standards in plant lighting and growers who went for these will most often never go back to anything else. As their flagship model, the Raging Kush 2 is definitely worth taking a look at.
HLG Scorpion Diablo

The SF 1000 and the TS 3000 are both great LEDs and they will teach you the basics of how to improve your yields with a small set of grow lights.

Spider Farmer SF 1000
The Spider Farmer SF 1000 is the perfect choice if you’re looking for a small light to cover just a couple plants, or maybe more than a few seedlings. Due to it’s great spectrum coverage it can be used for both purposes. It’s veg footprint is 3 x 3 ft, and the flowering footprint is 2 x 2 ft.
Mars Hydro FC 3000

Besides that, you can also improve your grow with the daisy-chain feature, which means you can connect up to 15 lights to be controlled through just one light.
Best LED lights for expert growers
Lastly, we’ve come to the hotly debated topic of what are the best LED lights for expert growers. There’s a lot of good choices out there, but we’ve chose one simple metric - the best LED for an expert grower is one that will give him the biggest yield. Lets take a look at our list of top 5 best LEDs for expers:
Best LED grow light for experts:
PhotonTek XT 1000w
The PhotonTek XT 1000w is arguably the best grow lights for expert growers at the moment. The “arguable” part is if their full capacity is being used for maximum results which is where the experts come into play.
If you are truly an expert grower, you’ll know that at one point the 1000w light intensity starts to bog down the plants, as they struggle to take in all the light due to a lack of CO2 in the growing environment. This can be fixed by supplementing the grow with carbon dioxide and controlling the environment with a grow tent and some CO2 controllers.
Growers Choice ROI-E720
The Aries is the home grown oriented grow light from Fohse. It boasts all the crucial aspect of a Fohse LED grow light but without the bells and whistles a commercial operation might need in order to bring the price in a more affordable range for hobby growers. That being said, you still get perhaps one of the best LED grow lights currently on the market.
Spring, Summer and Autumn modes. A sunrise and sunset feature. Not to mention the patent pending heat dissipation technology and so many features it would be too long to list here. If you are looking for the Rolls Royce of grow lights make sure you take a look at the Fohse Aries more in depth.
Nanolux LED X Modular
The Nanolux LED X Modular is one of the latest innovations available on the market. Needless to say they’ve somehow re-written the rules. The most interesting aspect of this fixture is included in the title: Modular. If you are an experienced grower and you already know a good deal about LED’s you’ll be blown away by this one.
With a wide range of bars to choose from you can literally build the grow light of your dreams by choosing your spectrum and spacing the bars in a way that delivers optimal results for your personnel needs. Backed by Nanolux acclaimed reputation, the LED X Modular gives you complete control.
The Fohse A3i could be compared to the Aries but here you get the absolute full package. The sheer amount of light this 1500W fixture produces is almost too much. However, if used correctly this LED grow light will do wonders for your plants. For this reason we recommend this product for experienced growers who will know how to make the most of all that power and ingenious features this fixture has to offer. T
he A3i is ideal for commercial purposes although it can also be a great option for veteran home growers looking to explore the next frontier of plant lighting technology.

The ROI-E420 carries the Grower's Choice famous GC-3K Full Phase Spectrum diodes which are said to be some of the best you can get for a full plant cycle and that includes young plants, as they perform significantly better than regular full spectrum diodes made for homes and offices.
Another important thing to note about the ROI-E420 is that this LED is made for 4’ x 4’ if you aim to flower with it or 5’ x 5’ if you want to use it for the vegetative stage. Additionally, it can be folded in half - making it significantly easier to transport or store.

The Kind LED X420 boast the same technology as it’s smaller brother the X220 but is made for larger grow spaces. As it is, this LED grow light will perfectly light up a 2’ x 4’ canopy.
One of the perks of this design is that if you eventually want to illuminate a larger space like a 4’ x 4, for instance, you only need to purchase a second Kind LED X420. This allows for a modular strategy to scale up as you increase the size of your grow operation.
The Photontek SQ300W is part of the latest generation of PhontonTek. With a bold design, this LED grow light is actually made of interlocking squares to provide optimal light coverage.
At 300W, this fixture is optimal for a 3’ x 3’ canopy so it makes a very interesting choice for home growers who are used to smaller grow spaces. Boasting the latest generation of top bin diodes and Photontek’s cutting edge components, this unit is worth every penny.

Best LED grow lights for greenhouses
Greenhouses are great for utilizing the natural sunlight and complementing it with additional light once the sun goes down. Here are 5 LED grow lights perfectly suited for greenhouses:
Best LED grow lights for greenhouses:
Fluence VYPR 3P
The Fluence VYPR 3P is one of the best greenhouse LED available on the market. Featuring a wide array of spectrums it allows you to pick and choose the exact supplemental lighting for your specific needs.
As with any LED grow light designed for greenhouse purposes, the VYPR 3p allows you to swap your HID lights with having to make fundamental changes to your current infrastructure. By doing so you can expect to save up to 40% in electricity costs all while providing a much more optimal spectrum to your canopy.
The Fohse o6i is the high output greenhouse model from Fohse. At 1200W it has been designed to replace your old DE HPS and this unit has all the features you can expect from a top manufacturer such as Fohse.
It has a slightly higher price point than its competitors but this shouldn’t be an issue if you consider that the o6i features industry leading components and all sorts of innovations that makes this LED grow light the most future-proof option available in 2021.
Scynce LED Dragon Alpha
The Scynce LED Dragon Alpha is a favorite among craft growers and the reason for this is simple. It features Scynce LED acclaimed tunable spectrum which allows it to morph into exactly what’s needed at any given time.
On top of that you get the build quality, wireless connectivity and other interesting features which make the reputation of Scynce LED unquestionable.

These are some of the fixtures we did not have the chance to review but are popular choices in the growing community.
This is an all-time favourite among growers and pioneered the Bar LED design along with a few other companies. With a very reputable background in HID grow lights, Gavita has lived up to the expectations with this fixture.
One particular feature of this light is the impressive amount of diodes. Although this does not necessarily improves the intensity, each diode is under-driven thus increases the life span of the overall system.
Thats certainly an underrated fixture in every way. A recent independent test ranked this fixture among the top performers in almost every category from efficiency to pricing and built quality. At this price it doesn't get much better.
What is the most powerful LED grow light?
According to some industry experts, the most powerful LED grow light on the market is the Gavita Pro 1700e Gen 2 LED. However, we’d like to differ as we believe that the Photontek XT 1000w and Fohse A3i when used with the proper CO2 supplements can really do magic for your plants.
If you don’t supplement the plants with CO2, they might start get light-burned to the high amounts of light this LED produces. Keep that in mind when making your choice and your plants will definitely appreciate it!
How do I choose the best LED grow light?
This one is totally up to you and your needs - however, many people don’t know what their needs really are. If you are just getting started, you have a couple plants, and you want to supplement them with a cheap light, you should probably go with one of the Spider Farmer models. The Spider Farmer LED lights are a highly reputable brand with a very good selection of cheap, yet very cost-effective lights.
On the other hand, if your needs are geared more towards a profession than a hobby, then we’d recommend looking into the PhotonTek, Scynce LED, HLG, Fluence, Fohse models. These come at a little higher price initially, but offer a lot of great features and customization opportunities which will definitely maximize your yields and help your plants grow faster.
What is the best wattage for LED grow lights?
The best wattage for LED grow lights is 30-35watts per ft² which can be a little tricky to measure. So, to break it down - best wattage for 4x4 LED grow lights is around 500w, while the best wattage for a 5x5 LED grow light is around 700-800w. Anything over that and you risk exposing your plants to too much light.
What lights do professional growers use?
Professional growers use LED lights in most cases, unless they are trying to experiment and compare results to other types of lights such as HID and HPS. LED lights are by far the most cost-effective lights out there, while also showing good and even better results than its competitors. HPS lamps are deficient in blue light which is why most professional growers use a combination of both metal halide and HPS lights, or just one set of LED lights.
Many professional growers use the Growers Choice ROI-E720 as these LEDs pack a very powerful punch. Besides that, they cover the full spectrum of light and use comparably little power to other models in the same price range.
Will any LED light work as a grow light?
Yes, any LED light will work as a grow light, as long as you have a good sense of placement. If you place it too far away from the plants, then they won’t receive as much light as they would if the light source was closer to them. This will result in slower growth and smaller yields. You could also set up a couple individual bulbs, but it’s always best to simply buy a fixture and hang it at the height recommended by the manufacturer.
What are the best LED lights to grow cannabis?
The best LED lights to grow cannabis are most likely Spider Farmer LED lights. The SF line has models covering all your needs. If you’re an expert grower looking for very strong, yet cheap lights - check out the Spider Farmer SF7000. If you’re just looking to get your first light and cover a couple plants, then the SF 2000 will be the perfect LED for you to start with.
My sq300 died after 6 weeks. Things happen which is why I went with an American company with a reputation to back it. Whelp 3 weeks later they finally responded to me. My first and last photontek purchase to be sure.
How come you never have the x2? Now that I have the money, I don’t think I want it anymore because it’s been a such hassle.
