I’m going to assume you’re in your 100th hour or so of reading the best LED grow light reviews you can find and you’re still no closer to making a decision.
I can make this assumption, because I’ve been there myself and I’ve helped countless others in the same situation. There are so many different options these days and, unfortunately, most of those options just aren’t any good.
You need to first eliminate all the useless LED lights. Then you need to decide which of the quality grow lights is best for your garden. It’s a daunting task.
On this page, I’ve narrowed the choices on Amazon down to the 8 best LED grow lights on the market. These lights give you the best results for a reasonable cost. I have not included any of the prohibitively expensive lights, nor any of the dirt cheap ones.
Best LED Grow Lights: Summary Of Recommendations
A lot of growers wrote in saying they didn’t want to read through each review and just wanted me to tell them which LED grow light is best. That’s why I added this short section.
Best Light Overall
The best overall LED grow light is the Phlizon COB series. It is not the highest quality LED light (see below), but it offers the best overall value to growers. It sells at a similar price to other similar lights, but has a bit more power and a slightly larger coverage area than most.
What really sets it apart is the perfect spectrum for plants, thanks to the mix of the white COBs and the colored supplemental LEDs. That makes it by far the best low-cost LED grow light for all stages of growth and one of the few COB LED grow lights you can find in this price range (and the only one that is any good).
Highest Quality Light
The highest quality grow lights are the Advanced Platinum Series fixtures and it’s not even close. As you may expect, they cost a lot more than the other grow lights on this page. That’s the only reason we did not choose one of these LED lights as the best overall.

Top LED Grow Lights — Reviews Of The 8 Best of 2019
The following grow lights are the 8 best options currently available on Amazon for indoor growers. By “best”, I mean they offer the best value. There are certainly better quality LED lights, but because they cost ten times as much, I feel the lights listed below give you the best results for your money.
These LED lights are also some of the best-selling grow lights on Amazon. They have a lot of reviews, too.
You’ll definitely want to read through those, especially the bad ones. I find you learn the most about a product from the bad reviews. If the negatives of a product are something I can live with, then I know I’ve found the indoor grow light for me.
The Platinum LED Advanced Platinum Series has six lights, from the P150 to the P1200. The smallest runs on 86 watts and is equivalent to a 150 watt HID light and the largest runs on 690 watts and is compares to 1200 watts of HID light (the one pictured on the left is the P450; this link will take you to the Amazon page that shows all 6 lights in the Advanced Platinum series).
The Platinum series of indoor plant lights enjoys a stellar reputation. They are the most expensive lights on this list, but they are still priced far below competing LED lights that deliver similar results. And they are far superior to any lights selling for a similar price.
In short, if you’re looking for great grow lights at a bargain price, you’ve found them. It’s worth paying a bit more money than you would for the absolute cheapest budget choice, since these plant lights will actually grow plants and get you a yield that matches an HPS system.
And that is the reason for my highest Grow Light Info rating ever: a 4.9 out of 5.
Features Of The Advanced Platinum Series Of LED Grow Lights
- 12-band spectrum with UV and IR — all the light your plants need for all stages of growth
- US-made top-bin CREE and Bridgelux LEDs — more output, while using less energy and longer lasting
- Rated for 100,000 hours — grow for 8-10 years with no bulb changes
- AC 85 to 260V input voltage — works anywhere in the world (all international cords available)
- Complete 5-year warranty and 90-day return policy — no purchasing risk
- Package contains grow light, hangers and power cord — everything you need to start growing immediately
We really wanted to include at least one plant light fixture that uses COB (chip on board) technology on this list, but most COB lights are much more expensive than the other options here. We’re trying to keep everything around the same price, apart from Advanced Platinum, because we feel this is the sweet spot of price vs. performance.
Luckily, there is one COB light that falls in the sweet spot and it is a great one: the Phlizon CREE COB Series 1000W. It sells for a similar price as the average on this page and delivers a better performance, especially where the light spectrum is concerned.
It combines two white COBS (one with a 3000K color temperature and one with a 600K color temp), with supplementary diodes to boost the spectrum in those wavelengths that plants need the most to grow (blue and red) and add some IR and UV light.
This LED light is extremely bright and covers a 3 by 3 area during flowering. During veg, it covers an area of 16 square feet. The other two lights in the series are more powerful and cover larger areas.
Phlizon call it a 1000 watt indoor light, but it is not. It gives you similar output to a 400 watt HID light, with a similar coverage area. It consumes 245 watts and delivers a PPFD of 941.4 umol/m²s at a hanging height of 18 inches.
The Phlizon 1000W COB ships with an adjustable ratchet hanger, a hanging kit, a power cable, grow glasses and a thermometer and humidity monitor. It is covered by a 2-year factory warranty and has a 30-day money back guarantee.
Features Of The Phlizon 1000 COB LED Grow Light
- 245 watt actual power draw — but 400w HID equiv., so you conserve on electricity over HID bulbs
- Top Rated CREE COBs — more efficient and last longer
- Daisy chainable — can connect multiple lights and run from a single power source
- Runs on AC100-240V — works for growers in any country
- 50,000+ hour lifespan — grow up to 5 years without bulb changes
- Perfect spectrum for plants — ideal mix with peaks on red and blue, but some light in every wavelength, plus UV and IR LEDs
- Includes 2-year warranty and 30-day returns — if you do get a bad unit, you can get it replaced
At first glance, it seems like King Plus is offering a 1000 watt LED light for an incredibly low price. Unfortunately, this is not really a 1000 watt LED grow light. Not even close. It’s basically equal to a 400 watt HID light bulb, in both coverage area and output.
So why is it on our list of the best LED plant lights?
Because, if you ignore the mislabeling, it is still a great indoor light (it is actually a series of lights). It sells for a very low price and with its 10 watt LEDs (Epistar 5 watt double chips), it penetrates far more deeply into the canopy than most competing lights of this size.
It has a great spectrum that is made up mostly of red diodes, a lot of blue and some white LEDs. This is very effective for plants during both veg and bloom, but I would prefer more white light.
It gives you 400 watts of HID power, but only uses 185 watts. It also has an incredible cooling system, including heat sinks and cooling fans, that effectively dissipate the heat from the powerful 10w chips. It ships with a power cord and hanger and also comes with a 3-year warranty. It has a lot of great reviews on Amazon, too.
Features Of The King Plus 1000 LED Grow Light
- Uses 185 watts — about 50% less power consumption than HID lights
- Matches a 400 watt HID system — but costs less to buy AND to operate
- Full spectrum light — can be used during all stages of plant growth from vegetative stage to bloom
- 9 square foot core coverage — same as a 400w HID
- Epistar 10w double LED chips — deeper canopy penetration than 3w or 5w LEDs
- Runs on AC85-265V — will work in any country
- Rated for 50,000 hours — 4-5 years with no bulb changes
- 3-year warranty — risk-free purchase
- Includes light, hanging kit and power cord — everything you need to start growing plants immediately
Meizhi is not as recognizable a name as some of the other brands on this list, but they make lights that are every bit as good for indoor growers. And they don’t exaggerate quite as much as most of the others (see below).
That said, they do compare this reflector series light a 600 watt, when it is only equal to about 400 HID watts, but that is par for the course with these Chinese manufacturers. You basically have to accept that and judge their lights on the merits.
And judged on its merits, this plant light deserves its place among the best LED grow lights. It draws 277 watts, which is more than the other similar lights on this list, but it also gives you a slightly higher output and larger coverage area, thanks to the 120 degree lenses.
At 12 inches from the plants, you get a PPFD of 1463 umol/s dead center and an effective coverage area of 3 by 3 feet (or 9 square feet) for flower and an extra foot of space each way for vegetative growing. Putting it in a grow tent is recommended, because the reflective walls increase the amount of light to maximize the square foot coverage and help plants grow.
Meizhi outfitted this light with the full spectrum of light needed for any stage of plant growth. It has blue light in the range of 450~475 nm, red light in the 620~630 nm and 650~660 nm ranges, and white light.
Unfortunately, it only has a few white LEDs and could benefit from more. Plants like to have good amounts of green and yellow wavelength light to grow more effectively, despite what many manufacturers tell you (mainly because their lights offer only red and blue light).
The Meizhi 600 ships with a power cord and a hanging kit. It is rated for a lifespan of 50,000 to 100,000 hours and that is backed up by a 3-year factory warranty and a 30 day return policy. You can daisy chain multiple lights together.
If you buy it on Amazon and don’t like it for any reason, you can simply return it for a full refund within 30 days, so there is no risk to you. This is a brand that believes in their lights.
Features Of The Meizhi 600 Watt Reflector Series LED Grow Light
- 277 watt actual power draw — but performs like a 400w HID, so you conserve electricity over HID grow lighting
- EMC chip packaging technique — the newest chip package technique, which offers better resistance to corrosion and water vapor, extending lifespan and improving performance
- Daisy chain capable — run multiple lights from a single power source
- Runs on 85-265V — works in any country
- 50,000-100,000 hour lifespan — up to 10 years without light bulb changes
- Full-spectrum light with blue, red and white diodes — great for all growth stages of plants
- Includes 3-year warranty and 30-day returns — if you do get a bad unit, you can get it replaced
The Viparspectra Reflector-Series V600 is another plant light proves that high quality LED grow lights don’t have to cost 5 times an HID system. In fact, they can cost LESS than many of the HID light kits on the market..
Viparspectra claim the V600 equals the output of a 600 watt HID system, but that’s not true. It is closer to 400 HID watts and it is this misleading claim that dropped it down a bit in our rankings. As a 400 watt equivalent, it would have made us bigger fans.
This Viparspectra fixture uses only 260 watts of power, saving over 50% each month on operating costs over HID, once you factor in cooling costs. For a large cannabis growing operation, that is a lot of savings.
It is part of the Viparspectra Reflector-series of lights, which range from the 300 (250 watt HID) all the way to the 1200 (950 watt HID). You can check out the full Viparspectra series here on Amazon.
These are all efficient full-spectrum plant lights that can be used for any stage of cannabis growth, from cloning to vegetative stage to blooming. They give you more output while using less energy and are especially effective in a grow tent.
The Viparspectra reflector-series lights offer 3-year warranties and Viparspectra is also including a 30-day satisfaction guarantee. That means there is no purchasing risk whatsoever.
You can try one of the best lights on the market out for 30 days and if you don’t like it, simply return it for a refund. Head to Amazon now by clicking below and read some of the great reviews this light gets. You’ve got nothing to lose!
Features OF The Viparspectra Reflector Series V600 LED Grow Light
- 260 watt power draw — save about 50% on your electric bill over HID lights
- Output similar to a 400 watt HID system — but costs less to buy AND to operate
- Full spectrum light — can be used during all stages of growth
- 2.5 by 2.5 foot core coverage — slightly less space than HID, but similar to competing LEDs
- 90° degree lenses — focus all the light onto your plants, so none goes to waste
- Runs on AC100-240V — Viparspectra lights will work in any country
- Rated for 100,000 hours — 8-10 years with no light bulb changes
- Includes light, hanging kit and power cord — everything you need to start growing immediately
If you’ve spent time on forums for growing, you’ve probably come across the Mars Hydro name. The reason for that is that they pay those forums to discuss their lights. You can’t fault them for advertising, but you do want to be aware that these lights are not as amazing as you might read.
Don’t get me wrong: they are good lights for the price. And the price is low. But there are issues to be aware of.
They’re a Chinese company, which means a higher incidence of faulty lights. Luckily, you can return it if you buy from Amazon, but you still lose time. Customer service has also been a problem in the past, but they now have a service center in California, so this should improve.
Bottom line: Mars Hydro lights are a great option to check out, if you’re looking to get a powerful light to help your plants grow at a low price. You just need to be aware of the potential issues.
Besides, those are issues all the lights on this page have in common, apart from the Advanced Platinum Series. That is why those lights cost so much more.
As for the light itself, I’ll list the main specifications here. For more info, see our complete review of the Mars300 or our review of the Mars reflector series lights. The reflector series are another low cost option from Mars Hydro.
Everything in the review for the 300 goes for the 600 as well (though both lights have recently been updated with newer tech that gives you more output, while consuming less power), apart from the specific numbers, of course.
For those, read the key points below or click on the ‘buy now’ button to head straight to the product page on Amazon, where you can find all the specs. Mars Hydro also makes a grow tent line and those go well with this light.
Key Characteristics Of The Mars 600 LED Grow Light From Mars Hydro
- 192 watt real power draw — but output of a 400 watt HPS, so you save over 50% on electricity over HID lighting
- VDE and UL-certified plugs and wiring — safe and easy to maintain
- Heat-proof tube — no fire risk
- Runs on 85-265V — works in any country
- 50,000-100,000 hour lifespan — up to 10 years without bulb changes
- Full-spectrum light with blue, red and white — great for all growth stages
- Includes 1-year warranty and 30-day returns — if you do get a bad unit, you can get it replaced
iPower’s 36 Watt 4 Foot LED grow light was designed to replace a T5 fluorescent tube and it does this admirably. It is a great light for veg and for clones that will get you rapid and strong growth.
Not only does it cost less than a comparable fluorescent bulb plus fixture, it also costs far less to operate on a monthly basis. It consumes less electricity, produces less heat (it doesn’t even need any cooling fans) and won’t need annual bulb changes (the LED chips last at least 4 years, but generally closer to 10).
This fixture emits a full spectrum light from red, blue and white diodes. In terms of spectrum, it can be used for any stage of plant growth, but at a 36 watt power draw, it isn’t powerful enough to maximize yield during flowering, for cannabis or any other plant.
As a fluorescent replacement, it isn’t meant to be a flowering light anyway. It is ideal for seedlings and clones or for vegging and it does all three far better than fluorescent lighting, with a higher lumen output per watt.
Key Traits Of The iPower Watt LED Grow Light With Stand Rack
- Full spectrum light with red, blue and white LEDs — can be used for all stages of growth, but best for seeding, cloning and vegging
- Height adjustable — always keep the perfect distance from the plants
- High-quality metal frame — sturdy enough support the light, but still lightweight (7.4 lbs)
- Low power consumption and heat output — save money on electricity over fluorescent lights
- On and off switch — no need to unplug it every time you want to turn it off
- Easily assembled — start growing in minutes
- 1-year warranty
Galaxy Hydro was bought up by Roleadro, but they kept some of the grow lights alive in their Galaxyhydro Series. The Galaxyhydro 2000 is the top grow light in the series. Unfortunately, it is not a great value, when compared to other grow lights on this list, but does still outdo most of the market.
It is priced on par with other 2000 watt LED lights, but is less bright and has a smaller coverage area than the top options on the market. You’ll definitely want to put it in a grow tent.
It is not a 2000 watt grow light by any means (none of them are, but this one falls shorter than most), so the name is definitely a bit misleading. This is a common tactic among Chinese brands in the space, and you’ll likely have noticed that every grow light on this list is mislabeled.
I really wish they could understand that we don’t like this type of exaggerated marketing here in the US. That said, apart from the higher price, this is a pretty good grow light that is plenty bright enough to flower a 3 by 3 area, which is where many LED lights in this price range fall short.
This light only has a power draw of around 300 watts, but gives you the output of a 400 watt HPS light, so you’re using about 60% 0f the power of an HPS system (a 400w system uses closer to 500w of power, when you factor in the ballast).
It’s a full-spectrum LED light that will work during any grow cycle, but it is very red-heavy. That means it is definitely better suited for flowering cannabis, than for veg. You want more blue if you are also vegging and ideally, you also want some green and yellow light.
Specifically, this grow light offers 7 different wavelengths: two red, two blue and one white, plus IR to UV. Basically, all the colors of light plants need to grow. Just not in the ideal ratio.
It has two large fans for improved heat dissipation, which further saves you money since you don’t have to run an air conditioning unit.
Several of these LED grow lights can be daisy chained together using the included power cord (you don’t need to pay for a special cord like you do with many competitors). Hangers are also included when you buy on Amazon.
Characteristics Of The Galaxyhydro 2000 Watt LED Grow Light
- Works on AC85 to 265V — use it anywhere in the world
- 230w power draw — about 50% less electricity than HID
- Contains UV and IR — for more potent yields
- CE, ROHS, and FCC certified — quality product
- Has 50,000-hour lifespan — no more expensive bulb changes
- Package includes grow light, power cord, and stainless steel rope hanger — everything you need to start growing immediately
- Includes 2-year warranty — if something does go wrong, you’re covered
Buying LED Grow Lights: Factors To Consider
Whether you’re new to growing indoors altogether or just new to growing cannabis plants with LED plant lights, you may not be familiar with some of the unique characteristics of LED lighting. Here are the main factors you want to check on when purchasing LED horticultural lights for your cannabis grow.
The factors are listed in no particular order. Only you can know which one is most important to you, given your specific growing situation.
Real Wattage And Theoretical Wattage
You may have noticed that most LED lights have two different wattage figures. One of these is the potential wattage and the other the actual wattage. The potential wattage is the wattage the light could run at if the LED chips were running at full power. For example, a light with two hundred 3w LEDs has a potential wattage of 600.
LED chips are never run at full power, though. Doing so would considerably shorten their life span. Generally, they are run at 50 to 60% of their potential power. This is their real wattage and is the amount of electricity the light will actually consume.
The 600 watt LED grow light from the example above would probably have a power draw of 300 to 400 watts. And lights listed as 300w don’t actually have a power draw anywhere near that much either.
Most indoor horticultural LED lights use LEDs in multiple colors. The majority will be various shades of red and blue, with the better lights also using some white LEDs as well as some infrared and ultra-violet ones.
This mix of colors gives you all the light plants, including cannabis, need for every stage of growth: cloning, veg and bloom. It is referred to as full-spectrum light and is generally what you want. All of the fixtures above, from Viparspectra to Phlizon, offer some variety of this light spectrum.
There are a few exceptions. If you are looking for a light to only grow clones or to just veg plants, then you might want to check out one with mostly blue LEDs. If you are looking for a light to supplement your existing setup to give your plants a boost during the flowering stage, you’ll want one with mostly red LEDs.
Finally, I need to mention all-white LED fixtures. These lights use only white LED, which gives them a spectrum similar to natural sunlight (which is also a mix of the HPS and metal halide spectra). Proponents of white light claim it is best for plants, because it gives them the light they are used to from the sun.
More and more, the indoor cannabis industry as a whole is moving toward white light. White LED grow light fixtures are becoming much more common on the market as a result.
And white light does work well to grow and flower plants. But it includes a lot of light in the yellow and green ranges, which is light plants do not use much during photosynthesis. Thus, it goes to waste, right?
That has been the case made by manufacturers (and fans) of fixtures with mostly red and blue LED lights. They say these are more efficient, because you are not using any of the electricity you paid for to produce light that plants don’t want.
But plants do want that light. Sure, they don’t want as much of it as they do of light in the red and blue wavelengths, but they do still want it. That is why the best-selling LED grow lights these days all include white LEDs on their lights. And many use mostly white LED light.
For LED lights, the most widely used measure of intensity is PAR. It stands for Photosynthetically Active Radiation and is used to measure the amount of light in the wavelengths that plants use for photosynthesis. Some brands will list the lumen output, but that isn’t all that useful for grow lights.
Some brands give PAR readings for their indoor plant lights; others do not. Those that do often only give one value, which doesn’t really tell you much about its effectiveness for vegetative growing, much less blooming.
That value was taken dead center beneath the light. A large value here means you have a powerful light in the middle of the coverage area, but it tells you nothing about the strength of the light around the edges.
Ideally, manufacturers will provide a PAR footprint that shows PAR readings throughout the coverage area. Most do not do this, however, so you will often have to look to tests done by third parties, such as review sites, for this information. For white LED lights, lumen output can have some value. For others, it is mostly useless.
This refers to the area a grow light can cover while still providing enough light for the plants in that space. For the flowering stage of growth, plants need more light, so you will have to move the light fixtures closer to the canopy. This increases the intensity, but also decreases the coverage area.
This is why LED lights have a smaller coverage area for the flowering stage than they do for vegging. Always make sure the space given by the manufacturer is for blooming, unless you only plan to veg with your light.
Te best LED grow lights give off far less heat than HID bulbs, but powerful LED diodes still emit enough heat that they require cooling. Any larger LED fixture must have heat sinks to reduce the amount of heat emitted and internal fans to disperse whatever heat remains.
You want to make sure that a LED light’s cooling fans and heat sinks are adequate for the amount and strength of diodes in contains. If it isn’t, this will considerably shorten the life span of the LED chips and make them far less efficient.
Another issue to consider is noise. Fans can generate a lot of noise, so fixtures with multiple fans will be much louder than you might think.
When you add their noise to that of oscillating fans and exhaust vans for your tent, you can end up with a fairly high noise level. If this is a concern, consider a fixture with fewer, or even no, fans.
General Info On LED Horticultural Lights
LED growing lights have come a long way since they were first introduced. Today’s LED lights give you yields equal to, and in some cases better than, HID lighting. They are simply far more efficient.
Older LED lights were great at vegging, but they fell short when it came to flowering. They just didn’t have the required intensity and the amount yielded from a given space suffered as a result.
Modern light emitting diodes are capable of handling veg and bloom.
During vegging, plants require more bluish light with wavelengths that range between 430-460 nanometers
During flowering, plants need more reddish light and also more intensity. This light has wavelengths that range between 650-700 nanometers.
Quality LED grow light manufacturers produce fixtures that provide several shades of blue and red light. Additionally, the best LED grow lights also have some white LEDs.
White LED Grow Lights
White light contains a lot of green and yellow wavelengths. Plants don’t use much of this light to grow, so you don’t want to have too much of it (like HPS and MH bulbs), but it’s good to have some. Finally, quality LED lights often also have some infrared and some ultra-violet light.
LED grow lights are energy efficient, specifically because they do not contain only white light (i.e. light in the yellow and green ranges). They provide the exact light plants need to grow and nothing more. This way, you are not using electricity to produce light that goes to waste.
Sunlight, for example, contains a ton of yellow and green light. Yes, it works well to grow plants, but that’s because it also contains the red and blue wavelengths plants need. All the other colors go to waste. Since the sun provides an unlimited supply of light, it doesn’t really matter that so much of it goes to wast.
Things are different when we are paying for it, though. That is exactly what happens with traditional grow lights, like high-pressure sodium (HPS), metal-halide (MH) and fluorescent light bulbs. They emit mostly unusable light.
And the same is true for all-white LED grow lights, despite what the manufacturers of those lights claim. Yes, they work, but they waste a lot of energy unnecessarily. That’s why the top LED grow lights have white diodes, but they supplement those with additional red and blue LEDs.
Common Uses For LED Grow Lights
LED plant lights are commonly used for the following applications.
LED grow lights might be used in greenhouses to supplement natural sunlight or the may be used exclusively for underground or indoor gardens
In urban area where space is limited, LED grow lights can completely change the way we grow food. They allow us to move grow operations into abandoned warehouses, old subway tunnels, etc.
Algae is now widely used to manufacture bio-fuel and LED grow lights are perfect for growing algae. For this application, grow lights that only veg (i.e. they have mostly blueish LEDs) are perfect, so you can spend less on electricity since less power is needed for vegging. They also run cooler.
This is the fastest growing area for LED lighting and it is revolutionizing the industry. Quality LED lights produce more and higher quality yields, while using less power and creating less heat. They are excellent for marijuana plants.
LED grow lights may cost more to purchase upfront, but the operating costs are much lower and the resulting light output is worth more.
Costs are reduced and revenues increase. Grow operations become much more profitable. And in the past few years, home growers have been switching to LED light for their marijuana plants in huge numbers, too.
LED Grow Lights Are The Future
LED grow lights can help a grower save up to 75% in energy consumption. They have a smaller heat signature as well, which saves even more.
Their incredible efficiency and their improved yields make LED light the horticultural lighting of the future. And for the countless growers who have made the switch already, they are the grow lighting choice of the present, too.
Top LED Grow Lights On The Market: Final Thoughts
Quality LED grow lights are the best solution we have today for growing plants indoors. They are more efficient that traditional forms of light, meaning they produce more output, while using less electricity and producing less heat.
They also last much longer. You won’t have to change bulbs for at least 5 years, and often over 10.
The Bad News
But there are downsides. Well, one big downside. And that is the proliferation of low-quality LED lights.
In the past five years, tons of brands have flooded the market with low-cost LED grow lights that are practically useless. They either only veg and do not have to light intensity required to flower plants, or they simply use the wrong spectrum to be of any use.
If you’re in the market for an LED light, I’m sure you’ve been doing your research and have come across a number of these cheap grow light fixtures. Those will not grow a plant, much less flower cannabis plants. LEDs like that are not a good choice and a huge waste of money.
Unfortunately, not all of these lights are easy to recognize; some of these manufacturers are very good at marketing and know how to make their LED grow lights appear far better than they are.
What can you do then to avoid making a bad choice and blowing your hard-earned money one useless LEDs that your plant will hate as much as you?
You’re already doing it.
The Good News
Sites like this one wade through all the crappy choices and find the quality lights. And they don’t always have to be the most expensive options either (Platinum LED is a good example of this). You can get really good LED grow lights for not too much more money than their HID plant light equivalents.
Even if the best LED grow light is not necessarily the most expensive, LEDs will cost at least a bit more money than other forms of plant light. Those LED grow lights selling at rock bottom prices are the ones you want to avoid. The bad choice.
Pay a little more for a huge jump in quality, in terms efficiency and light spectrum. If you are not willing to do that, you are not yet ready to switch to LEDs.
And that’s fine. HID and fluorescent lights have worked for decades for growing cannabis plants and other plants as well, and they still work well today. LED grow lights just work better.
