Top 10 Best LED Grow Lights in 2021 to Grow Cannabis Indoors

#1 – New Spider Farmer SF-4000 LED Grow Light Review

Spider Farmer SF 4000 Review

New Spider Farmer SF-4000 is a beast LED grow light with super solid powers.


Spider Farmer SF 4000 ReviewThe LED light brings a very durable form produced using light metal. The brilliant light arrives in a quantum design board that looks very alluring.

Unlike many other LED grow lights, the Spider Farmer SF-4000W LED grow light has a fanless design, which decreases the LED’s overall weight.

This is advantageous as the requirement for adjusting lighting while at the same time growing is consistent, and a grow light that weighs less is easier to position inside your best grow tent.

Upgraded SF series LED Grow Lights have a dimming knob and light switch.

Energy Efficiency:

Spider Farmer SF 4000 Review

The light uses the latest driver technology in its Mean well driver. This driver assists with regulating the flow of light for a consistent full spectrum balance.

It also assists with its overall efficiency by not wasting energy when it does not need to.

By consuming only 450 watts of electricity, the Spider Farmer SF-4000 watt LED grow light also offers better micromoles/joules as compared to the grow lights in the market.

The current quantum lights also use brand-new versions of diodes that do not consume as much energy as the traditional diodes.


The way the Spider Farmer SF 4000 evenly spreads light over its coverage area, we think this is an extraordinary feature compared to other LED grow lights on the market.

It has excellent full-spectrum-white, blue, red, and IR (3000K, 5000K, 660nm, and IR 760nm). 3000K diodes are providing more reddish light and 5000K, providing more blueish.

The 660nm red and IR light is especially useful during bloom, where it speeds up flowering time and boosts yields.

#2 – PhytoMAX-2 600 LED Grow Light Review

Phyto MAX 600 Review

The PhytoMAX-2 600 watt LED by Black Dog will definitely give you the best results within its category.

The 5-watt diodes have incredible heat management as well. You will be most likely to have high-yielding plants in just a short period of time with this product.

At 630 original watts and 961 μMol/s total photon flux, the patent-pending PhytoMAX-2 600 LED growing lights will outperform any single-ended 1000W HPS light.


Phyto MAX 600 Review

The ultra-quiet, long-life fans give the best dynamic heat management in the industry, which is crucial to maximizing LED life and spectrum stability.

PhytoMAX-2 600 uses 5-watt diodes spread evenly over the PCB, which ensures even light distribution and coverage.

This design reduces hot spots and leaf burn, compared to other LED grow lights, which contain less powerful LEDs over the equipment and can prompt hotspot issues.

The power-packed design of this model offers great results, and you won’t think of changing it soon enough.

Energy Efficiency:

Phyto MAX 600 Review

At 630 watts, this light uses less power than its competitors. But Black Dog lights do not have an adjustable spectrum or even separate modes for veg and bloom.

The heat output system is Black Dog’s biggest plus point as their advanced heat control is what allows them to pack their fixtures with powerful 5-watt diodes and not endure the consequences of their increased heat output.


Black Dog fixtures distribute their light considerably more evenly throughout the coverage territory.

While you get less power on the inside than some lights, you get more power on the outside of the coverage region and more average power overall.

A typical complaint about most LED lights is poor canopy penetration. Most LEDs genuinely don’t give you a similar penetration as a powerful 1000 watt HPS bulb.

That is not an issue here, however. Black Dog uses just 5-watt chips in their lights, which means they have the intensity to enter profoundly into the canopy, just like HPS light.

How to Set up PhytoMAX-2 Grow Lights?

Hang it up. Plug it in. Turn it on. It’s that simple. There’s no additional preparation or setup required!

Black Dog Series Review

The PhytoMAX-2 series includes an adaptable driver evaluated for 120VAC or 240VAC. The unit is delivered with a 120VAC power cord, so if a 240VAC cord is required, you need to mention it at the time of ordering.

Hanging stature varies for every one of the different lights and for the vegetative and flowering footprint. As stated previously, it ensures you have enough freedom to hang the PhytoMAX-2 grow light in your grow room or tent.

You can use the flowering footprint sizes for vegetative growth. However, you may need to increase the use of fertilizer and CO2 to utilize the additional light if you are vegging in an area smaller than the medium recommended flowering footprint.

New Spider Farmer SF Series Review

Spider Farmer was established in 2015. It has progressed significantly since then, always being committed to giving its customers the most recent and best technology for indoor plant LED grow lighting.

They also design and sell grow kits systems and grow tents, to achieve their name as a farmer.

New Spider Farmer SF series includes:

  • New Spider Farmer SF-1000

How to Set Up New Spider Farmer SF Grow Lights?

The SF-1000 is incredibly easy to set up and get running. No assembly is required, as you can remove the grow light directly from the crate; everything is prepared to use right away.

You just have to plug it in and turn it on. It uses high-quality Samsung LED diodes. The grow light board can be situated in several different angles or styles.

This probably won’t appear a very serious deal, but it means you won’t need to supplant the LEDs very often since the parts are so well made.

Besides, the Samsung diodes make better canopy light penetration and furnish 40% higher yields with less energy, even compared to other red and blue light boards.

It’s also designed without a fan, which creates less commotion and makes it perfect for indoor cultivation.

LED or HPS — Which One is The Best?

There’s a lot of dispute among growers about whether HID lights (HPS and Metal Halide) are better than LEDs. But the truth is, one isn’t holistically better than the other; it just depends on your requirements and preferences for your growth.

In the photometric study, LED grow lights seriously beat HPS grow lights. This is mainly down to the wavelengths of light the grow lights offer.

Plants need light beyond the red and blue spectrum to fulfill all of their biological functions. LED grow lights mostly have the full-spectrum designed, including infrared and ultraviolet, with up to twelve distinct colors of diodes.

It can also set its balance of how it creates those kinds of light so that it’s always right for your plant’s growing stages.

The HPS spectrum is less efficient, because plants need very little yellow light, and most of the HPS light output is yellow. This means loss of light and money and lots of extra heat. HID custom lighting, such as metal halide, presents many of the same restrictions.

Find The Best LED Grow Lights for Your Cannabis Growth

When you plan for growing cannabis in an indoor setup, one of the most critical decisions is what kind of lights to use for maximum benefit.

There are many varieties of grow light fixtures, including High-Intensity Discharge or HID grow lights, Ceramic Metal Halide (CMH), High-Pressure Sodium (HPS), Metal Halide, and regular old standard Fluorescent Lights.

However, as the best all-around indoor plant grow lights, we recommend LED (Light Emitting Diodes) grow lights.

LED grow lights are comparatively new to the marijuana growing scenario. They have become wildly successful over the last few years with their ability to provide high yields while staying cold and using a moderate amount of power.

LED Grow Lights: Smart and Effective Solution- Buying Guide 2021

LED is a short form used for light-emitting diodes. These lights have swiftly come down in cost, and home breeders have started to switch to use them as their new and better lighting alternative.

These lighting systems create less heat, arrive ready to plug-and-play, and deliver high yields with incredible energy competence. Whereas the competitors of LED grow light need a reflector and ballast to operate, LED lights do not.

LED grow lights can last for a longer period of time, whereas other ordinary bulbs will frequently need to be changed every couple of years.

One of the prime reasons LED grow lights are considered the best is the spectrum they provide.

Why Do You Need LED Grow Lights?

There are definitely many advantages to going with LED grow lights, but whether they’re the best option for indoor cultivation depends on some factors.

For many expert growers, the moderate temperature, efficiency, lifespan, size, and coverage of LEDs make them perfect for the indoor cultivation of their plants.

Types of LED Grow Lights

There are 3 basic types of LEDs that are most generally used for growing marijuana. Each type of model has its advantages and disadvantages. Some are better for some circumstances than others.

1) Spread

Many smaller LEDs reached out over a wide area. Examples of this style involve Quantum Boards, Rack, and Spider style LED grow lights.

  • Quantum Board

The title “Quantum Board LED Grow Light” was introduced by Horticulture Lighting Group, though the name is now sometimes utilized for any LED in this form.

They have comparatively low wattage diodes, which are divided out over a large area on board.

  • Spider LED

The Spider style LEDs are just like Quantum Boards since every single diode is laid out evenly and tends to be on the smaller side. They are fixed on a panel with “arms” like a spider instead of a solid board.

These are typically high in price, but breeders who use them surely get better results than any other type of grow light.

2) Traditional Panel

The conventional panel LEDs have small to medium wattage diodes, and the lights tend to be more compact. Most LED grow lights accessible today are in this style. These are kind of halfway between a Quantum Board and a COB Style light.

There are Hybrid LED grow lights also available in the market that contain a blend of big and small LEDs and unique design factors that combine and match between all the styles.

3) COB Style

These grow lights utilize huge COB (Chip on Board) LED bulbs. Each COB is extremely bright and powerful because they contain many LED chips in a small area. COBs produce a brighter light than other types of LEDs, and each COB uses a significant volume of electricity.

Instead of possessing dozens of small diodes, COB LED grow lights typically only have a few big COBs, each with durable lenses to focus the light down into the plant.

  • AutoCOBs

It’s also typical to see LED grow lights that only have one COB per light. These make it simple to spread your light over a growing area, one lamp at a time. Sometimes they are recognized as AutoCOBs.

Things to Know Before Buying LED Grow Lights

There are so many essential factors while picking the best LED Grow Light. Here are the most significant ones:

  • The Requirements of the Plant

Light cycles can severely affect your plants’ growth and potency. Some plants need full brightness from a high-intensity source, and others might get blotted out or burned with too much, so you need to make sure what kind of output your plants need before buying grow light.

  • Spectrum

Grow light spectrum indicates the electromagnetic wavelengths of light generated by a light source to boost plant growth.

LED grow lights help balance plant production due to their full light spectrum abilities, low heat loss and maintenance, and long lifespan. LED grow lights can efficiently increase yield in plants at particular times in the growth cycle.

  • Energy Efficiency

Full-spectrum LEDs save more energy, too. They are reliable, normally, run cool without extra fans, and cost less in electricity bills.

The higher the output (wattage), the more electricity you’ll be consuming, but not proportionately. If you want 1000 watts instead of 500, you still won’t see double as much power dissipation.

  • Control and Customization

Remember that you need to change the light duration depending on the growth cycle to ensure that your plants flourish.

Don’t go with manufacturer specs, particularly when it comes to the coverage space. Your LED grow light system simply has to meet the right area for your plants.

PRO TIP: If you’re growing with a hydroponic method, you need to have access to the real power and water sources for that arrangement and your lights. This might require some planning in a smaller space.

  • Estimating Your Budget

This is critical but obviously necessary. Higher-end lights often provide better results, but a budget only works if each part fits. Beginners may want to select less costly grow lights to get expertise.

The LED grow light is not the only component you’ll require for your indoor grow operation. Your budget also has to include soil, fertilizers, nutrients, filters, grow tents, and various other equipment.

Since quality is the ultimate goal, brand matters, you need to do proper research before going for your final purchase.

Some Common Mistakes to Avoid While Buying LED Grow Lights

One of the biggest blunder growers do is the absence of research before beginning your marijuana cultivation! The following are the most common mistakes people do with LED lights. Read them carefully and try to avoid them:

  1. Buying the inferior quality lights
  2. Overwater the plants when the cycle changes
  3. Overheating the plants
  4. Adjusting the distance incorrectly
  5. Wrong spectrum
  6. Incorrect schedule
  7. Not maintaining the lights
  8. Focusing only on lights – not on other growing factors
  9. Crowding too many plants under one light
  10. Forgetting to adjust the light
