LED Grow Lights for Cannabis: A Beginner’s Guide

If you’re just getting started with growing cannabis indoors, one of the biggest decisions you’ll have to make is choosing the right type of light. Lights are crucial to growing weed indoors—after all, light is what keeps your plants thriving. In this guide, I’ll walk you through LED grow lights and why they’re a great option for beginners. We’ll cover everything from how LED lights work to why they’re often considered the best choice for growing weed indoors. Let’s dive in!

Why LED Grow Lights Are Perfect for Growing Weed Indoors

If you’ve heard about LED grow lights for cannabis, you might be wondering why everyone seems to be using them. It wasn’t always this way—LED lights weren’t always as popular with cannabis growers. However, as technology has advanced, LED grow lights have become a go-to option. They’re now among the best lights for indoor growing, offering energy efficiency, low heat output, and ease of use, which are all essential for beginner growers.

Advantages of Using LED Grow Lights

LED grow lights offer a ton of benefits for cannabis growers. Let’s look at some of the main reasons why these lights are a game-changer for indoor growing:

  • Energy Savings: LED grow lights for weed consume much less electricity compared to traditional HID lights. This can save you around 40% on your energy bill. For beginners, this means less worry about high electricity costs.
  • Long Lifespan: Good LED grow lights last between 50,000 to 60,000 hours, while HID lights often burn out after just a few thousand hours. That’s a big difference, meaning fewer replacements and less hassle.
  • Less Heat: LED lights produce significantly less heat, which means you won’t need a complex cooling setup. This makes them especially beginner-friendly—you don’t want to deal with heat stress or risk burning your plants. Plus, it’s safer since the risk of fire is much lower.
  • Compact and Easy to Set Up: LED grow lights don’t take up much space. They’re easy to manage and can be used in small indoor grow areas—perfect if you’re growing in a closet or a small room.
  • Focused Light: LEDs come with lenses that focus light directly onto your cannabis plants, making them more efficient. Unlike other lights, there’s no need to use bulky reflectors.

Are There Any Downsides?

The main downside to LED grow lights is the upfront cost. High-quality LED grow lights can be pricier than other options like CFL or MH/HPS lights. But think of it as an investment: while they might cost more at the beginning, they end up saving you money in the long run due to energy savings and a longer lifespan. You’ll also need to make sure your LEDs have proper heat management—though they don’t run as hot as HPS lights, they still produce some heat that needs to be dealt with, usually with built-in heat sinks.

Comparing LED Grow Lights to Other Grow Lights

Now that you know the basics, let’s compare LED lights to some of the other common grow lights out there, like CFLs and MH/HPS lights.

LEDs vs. CFLs

CFLs (compact fluorescent lights) have been used by cannabis growers for a long time. They’re a decent option if you’re on a very tight budget, but LEDs are far more efficient. CFLs generate more heat and need to be placed much closer to the plants—meaning more daily adjustment. LEDs, on the other hand, don’t need to be moved as often, and they’re equipped with cooling systems that make them safer and easier to manage. If you want to save time and effort, LED grow lights are definitely the way to go.

LEDs vs. MH/HPS Lights

MH (metal halide) and HPS (high-pressure sodium) lights are another popular choice. They can be cheaper upfront but use more electricity and get much hotter, requiring extra fans or cooling systems. MH/HPS lights do produce great yields, but many growers are switching to LED grow lights because they offer more control over heat, cost less in the long run, and can even produce higher quality buds with more trichomes and richer aromas.

How Do LED Grow Lights Work?

LED grow lights provide the optimal light spectrum for healthy cannabis cultivation.

LED grow lights work by passing an electric current through a semiconductor, which produces light. What makes them different from other types of grow lights is that they can be made to emit very specific wavelengths—perfect for cannabis growing. Most LED grow lights for cannabis are full-spectrum, which means they cover everything from blue light (for veg growth) to red light (for flowering). This makes them versatile and efficient for every stage of growth.

Understanding Light Spectrum

When you’re looking for the best LED grow lights for cannabis, you’ll want something that offers a full spectrum. Full-spectrum LEDs mimic natural sunlight, covering the range of light that plants need to thrive. Here’s a quick breakdown:

  • Blue Light: Encourages vegetative growth—this is what makes your plants grow tall and strong.
  • Red Light: Essential for flowering, helping your cannabis plants produce big, healthy buds.
  • White LED Lights: Often referred to as the best grow lights because they closely mimic natural sunlight, ensuring your plants get everything they need for healthy growth.

Understanding Key Terms: PAR, PPF, and PPFD

When choosing an LED grow light, understanding these technical terms can help you make an informed decision:

  • PAR (Photosynthetically Active Radiation): This refers to the spectrum of light that plants use for photosynthesis. LEDs with higher PAR output ensure more effective growth.
  • PPF (Photosynthetic Photon Flux): Measures the total light output of a grow light in micromoles per second (µmol/s). Higher PPF means more light photons are reaching your plants.
  • PPFD (Photosynthetic Photon Flux Density): Indicates how much light reaches your plant’s canopy, measured in µmol/m²/s. Aim for specific PPFD ranges based on growth stages:
    • Seedling Stage: 200–400 µmol/m²/s
    • Vegetative Stage: 400–600 µmol/m²/s
    • Flowering Stage: 600–1000 µmol/m²/s

Choosing the Right LED Grow Light for Your Setup

Picking the best LED grow lights for weed depends on your grow space and budget. Here’s what to look for:

  • Wattage: For smaller grows, a light between 200-400 watts will do the job. For larger spaces, go for higher wattage—something above 600 watts.
  • Spectrum: Look for full-spectrum LED grow lights, sometimes labeled as “white light” or “multi-band.” These lights will support your plants from seedling to harvest.
  • Heat Management: Make sure your LED lights come with good heat sinks or cooling fans. This is crucial for keeping temperatures in check and ensuring the longevity of your lights.
  • Ease of Use: Look for simple setup and maintenance. Adjustable height and dimmable options are a bonus.
  • Durability: High-quality materials and warranties ensure long-term reliability.

Advanced Features to Consider

While not essential, the following features can enhance your growing experience:

  • Dimmable Intensity: Allows you to adjust light output for different growth stages.
  • Spectrum Control: Some LEDs enable wavelength adjustments to optimize growth phases.
  • Daisy-Chaining: Connect multiple units for larger grow spaces.

Common Problems and Tips for LED Grow Lights

Using LED grow lights is easier than using traditional grow lights, but there are still a few things to keep in mind:

  • Light Distance: Always check the manufacturer’s instructions on how far your LED grow lights should be from your cannabis plants. If your plants start showing signs of stress (like curling leaves), the lights might be too close.
  • Color Changes: Sometimes, LED lights can make your plants look different—discoloration doesn’t always mean there’s a problem. Just keep an eye on the overall health of your buds.
  • Quality Matters: With LED grow lights, you often get what you pay for. Cheap lights might not provide the full spectrum your plants need, leading to lower yields and quality. Invest in good quality cannabis growing LED lights for the best results.

Reputable LED Brands to Consider

When you’re ready to buy, make sure you choose from reputable brands. Here are some well-known names that cannabis growers trust:

  • Mars Hydro: offers a diverse range of LED grow lights suitable for various growing environments. The FC-EVO Series, for instance, utilizes Samsung LM301H EVO chips, providing high efficacy and a full spectrum of light beneficial from seedling to flowering stages. These lights are designed to enhance flowering, resulting in higher quality crops and greater yields.
  • Horticulture Lighting Group (HLG) based in the USA, is acclaimed for its Quantum Board LED grow lights, which offer high efficiency and superior light distribution. Models like the HLG 550 V2 R-Spec are designed to replace traditional HID lighting systems, providing a full-spectrum light suitable for all growth stages. HLG’s products are known for their reliability and performance, making them a popular choice among indoor growers.

Why LED Grow Lights Are the Best for Beginners

LED grow lights are an excellent choice for beginners because they’re energy-efficient, easy to set up, and produce less heat. You don’t need to worry about complicated cooling systems, and you’ll save money in the long run. Plus, the quality of the buds—dense, potent, and flavorful—is hard to beat. If you’re planning on growing weed indoors, the best grow lights you can get are LED grow lights.

Now that you know what makes LED lights such a great option for cannabis growing, you’re ready to get started! Just remember to keep an eye on light distance, invest in quality lights, and, most importantly, have fun with your grow.

Happy growing!

    • Earl,

      I would check the footprint of those lights and I would also confirm that they are actually 200 watts each. Many LED lamps have are as powerful as advertised.

      I think you may find you need 4 more of those 200 watter for that space. Personally; I would have gone with a couple Digital 600 watt HID lamps.

      Great space. Happy growing.

  24. Best information I’ve read– but still confused by what leds to use if I have 2 or 3 seedlings. I was looking for x amount of light for x sq footage of area. Do I measure light first by watts? (assuming I have the budget to get the best spectrum, assuming I scrog, assuming … oh I don’t know anymore. So many posts talk about gram yield per watt but based on the above, that is a nonsensical shorthand. I just want to maximize yield for 2 plants. Sigh. I was going to go with 1, 400 watt light (under $100 on amazon) but if can top and scog to get each plant to cover 2 sq feet, then I am thinking I need 2 of them. All these posts that just discuss yield per watt seem to be missing square footage first, much less the quality of the LED spectrum and angle of light. Am I wrong?

    Reply
    • Rosey,

      You started out asking about a light for seedlings. Almost all Pro growers and experts use a T5 fluorescent lamp. These are available in 2′ or 4′ with 2 or 4 lamps in each.

      A 400 watt LED is generally 180-200 watts. This varies from manufacturer to manufacturer. Any L:ED under 100 bucks is a cheap lamp and will only last a while. you can use them to grow but, expectations must be tempered.

      gram per watt does not matter unless you as a grower can produce that. gram per watt os only something to be measured after harvest to keep track of how well you and your set up are doing. footprint is how LED growers judge which lamp to use.

      I suggest you go to ilgmforum.com, open an account and ask “latewood, I need help with lighting” in the title. I can show you what you need with pictures in the forum.

      See you there.

  25. So I’ve read a ton of articles and no one seems to have a general consensus on exactly how many foot candles and/or LUX is recommended for plants under an LED. I’m fully aware of PAR and lumens, and the problems associated with LED lights too close to the plant (bleaching). I’ve seen a ton of charts and blog comments, but have yet to find any that just give an optimal number of foot candles. I’m just looking for someone with experience who can give an approximate number that the canopy should be getting for the 12/12 cycle. Please don’t “help” me by explaining the difference in lumens, par, and FC/ Lux or with a ton of formulas- THANK YOU!

    Reply
    • The LED industry does not equate lumens to successful lighting. this is why you cannot find what you are looking for. LED companies “the good ones” look for leaf surface temperature, and proper light spectrum.

      I suggest you join our forum, suppoer.ilovegrowingmarijuana.com and look in the ILGM Podcst category under :”growing with Fishes”, and find the Spectrum King episodes. One was in May, and the other in July or August; I think. You questions will be answered in those podcasts.

      Veg photo period should be in between 14 and 18 hours on. If your LEd will not run longer than 14 hours; You shoudl find an alternative lighting system. I never heard of any light being limited to 14 hours. Never use over 18 hours of light’s “on”

    • Shenandoah,

      I am sorry to say; A 9watt lamp is not going to produce much yield at all. PLace the lamp as close as you can get it without making the back of your hand “HOT” if hand is placed palm down at top of plant. If hand get’s hot; Move lamp a couple inches higher until it is not hot at top of plant.

    Have you read out free grow bible? Even better yet. Join our free grow support forum and get help from our many helpful and friendly members. If you want some help from me. Post latewood in the title.

    Have a great day. See you soon! 🙂

  45. I’ve got led bulbs (purchased for regular in home lighting) they look like an old school incandescent bulb and produce a (white light like in home).
    Stats: 800 lumens
    Soft white 3000k

    Is this a “white led light” as you describe?

  46. Kiri,

    I believe that a wide spectrum of light is better for Cannabis. White light is great. I believe you would benefit more from a wider range of growers and opinions on LED lighting, if you joined our support forum

    LED lighting is still new to the Cannabis industry. We are just now getting to the point where you can find a bit more affordable LED systems.

    I still use T5, Metal Halide, and High Pressure Sodium. NH and HPS lamps ; (HID lamps) is still the lighting of choice for large scale and professional growers.

    Hope to see you in the forum 😀

  47. Purchased from ILGM and never heard from my order, nor received my order. I have tried to find contact info or an email address for Mr. Bergman to relate my woe but cannot find any way to reach him or the company that was suppose to ship my product. I am feeling pretty much like I have been ripped off. I plan on contesting the CC charge and asking for a refund if I can’t get what I paid for in good faith. My order was placed in April and we are heading towards the end of May. NOTHING…NADA…ZIP…my advice is be cautious if you try to deal with ILGM. Bad Taste here!

    • Mayfield,

      This is not true! Perhaps you have not received your order but ILGM always replaces seeds for lost or seized orders and even for unsuccessful germination. 100% of the time. email [email protected]. This email is all over the site.

      As proof; I challenge you to join our support forum and post what you posted here. You will find many, many satisfied customers that will dispute your claims, and vouch for the honesty of ILGM.

      Again; We are not claiming you did not get your seeds. Thsi blog page is not an appropriate place to trash talk ILGM.

      • Amen. Find another site to bitch. An open forum @ ILGM is NOT where you go to complain! I’ll give you the benefit of the doubt and assume you’re honest. They state 25 business days before refunds. You’re giving ME a bad taste…something stinks.

    • So not true, first of all they claim delivery avg time 5 days, but anywhere between 5 and 25 days, if you don’t get anything after 25 days to contact them. I emailed them on the 26th day just so they would know and they replied within 24 hrs.They said they would re-ship and if by any chance I’d get the first order to just keep them both for free and just to let them keep track of missing product. After 12 days I got my delivery and 5 days later a couple of seedlings.

    • I have to disagree. I ordered from ILGM and my seeds were here in 2 weeks. Every time I contacted them they got back to me.

    • They have been excellent for me. Even when I had problem, it was solved within 2 weeks total. Try again bud , they’re legit.

  48. Robert Says “You need white LED lights.(c)”. But where to buy lamps with white leds?
    Pro-Glow, King-Led and other listed companies still offer lamps with combiantion of red-blue-orange-white-IR leds.
    Thank you.

  49. You should look into the King Plus series of LEDs. A 1200 w unit runs about $212 used and is completely able to replace a 1000 w hid. I am currently using 2 800 w units and am about to add a 1200 and will still be under $600 in lighting investment. The grow quality is pretty nice. I will submit some pictures soon. I just super cropped and they need a couple days to pretty back up.

    • I was thinking of getting two King plus 1200 watt for my 8×4 tent but I’ve only seen one other posts which was actually nice for auto flowers. Any more info on this brand will be appreciated greatly.
      Thank you and Happy growing
