There are several factors to consider when choosing the best light to use for your grow room. Among these are as follows:

  • Make sure that the light you use has the power to illuminate the entire growing area.

This may differ depending on the light needed. Obviously, grow lights that clones and seedlings need are not the same with that of a weed growing to its maturity in one area.

  • Type of light needed

Will you need an all-purpose light and will it require additional supplemental lamps for flowering and vegetation?

  • Bulb Replacement

When using LED lights, bulb replacement may not be necessary. It has no temperature and ballast issues as well. However, such is not the case if you use HID HPS lights.

Below are the product reviews of the top selling LED grow lights including their covered area. This information will assist in determining the need of your grow area.


Choosing the Best Grow Light

Below are some of the things you must always remember when selecting the best grow light to use:


Make sure that this is within your budget range. Also, make a list of all the features that you need then factor in the amount of money you plan to spend.

Area to be covered

You can never know how much LED lights to use when you haven’t even seen the area where they will be used. Aside from knowing the numbers of LED lights needed, you must also check which one has the best coverage. To cover more area, place lights near each other.

LED lens angle

The LED bulbs must also be assessed for their angle of dispersion within the bulbs. There is more coverage if there is a greater angle while there is less dispersion with lesser angles and more direct light.

Phases of Growth

Full spectrum LED grow light must be used for a full growth cycle to aid in the entire growth phases.

Reasons for choosing full spectrum LED grow light

This is the latest lighting system introduced in the market these days. Hence, not many growers know about it. A lot of people thought that giant fluorescent is the best when it comes to growing lights for indoor marijuana garden. But the truth is; they aren’t. It is still better to employ full spectrum light systems since they resemble the effects of real sunlight.

Below are other reasons why full spectrum LED grow light is still your best choice:

  • More affordable when used over time.
  • Have greater yields
  • No need to use ballast and does not flicker.
  • No need to use additional fans since they don’t overheat.
  • Can be used for 50,000 hours or even more. Hence, there’s no need for any service for years of use.

So if you are using an outdated system, may as well upgrade to full spectrum LED panel as soon as you are able to.

Items that must be included in your “grow room kit”

  • Fertilizers and nutrients

Plants need their own minerals and vegetables too. This significantly affects their yield. On top of that, they affect the plant’s flavor as well. So make the right nutrient selection so you wouldn’t end up with a poop flavored pot.

  • Sunglasses

This is essential when using a full Spectrum LED light since with this type of light, UV rays can be present too.

  • Grow tent

This is helpful, even for those who already have enclosed space or closet for their marijuana plant. Grow tent is beneficial to growers since, with this, they can control the climate. Your weed will also have the protection it needs from stray light sources, especially when the weed has to stay in the dark. This helps control smell and humidity too.

  • Light meter

No, this is not only for advanced growers. You can use it too. You just need to know how to use it.

  • Hygrometer and thermometer

This is important for you to know the grow tent’s ambient conditions. We have reviewed these products on this site too and help you know the leading products these days that are guaranteed to last for many years of use.

BEST LED Grow Lights That Are Worth Your Money

Advanced Platinum Series P900

This is the editor’s choice. It comes with revolutionary full-spectrum technology. That’s what PlatinumLED grow light’s Advanced Platinum Series is. This product takes pride in its ability to give light at three times more brightness intensity than other LED grow lights.

Moreover, this type of grow light comes with 12 bands light wavelength. Among these are ultraviolet and infrared. The ultraviolet lights are lights that can’t be seen by the naked eye. When used indoor, this resembles the rays of a sunlight. Most of all, it has a panel that works well in every growing stage of cannabis.

To keep the light in a low key, you can hit “Veg” switch. You can also kick the intensity up by flipping “Bloom’s” switch. The LED focusing lenses comes with a 90-degree angle which is responsible for sending light to your plant’s canopy. This results in a significant plant growth.

Advanced Platinum Series P900 can be used to replace 1000 watt HPS light using full intensity. With Advanced Platinum Series P900, you will only use 515 watts for your electricity. If you are living in the US, electricity consumption costs 12 cents per hour, not to mention the amount you need to pay to cool it. However, with Advanced Platinum Series P900, you can expect better quality and experience the light’s full intensity and just pay half the price.

When Advanced Platinum Series P900 is placed 18 inches over the plants, it can cover around 3-5 feet. These numbers are important since they determine how much light is needed by your plant. You will need to increase or decrease lighting, depending on what your plant needs. If the plant is still sprouting, the light can cover from 4- 6 feet. However, during the flowering stage, your plant will need an intense light and this can be possible by only covering a small area.  In a 3 gallon pot, 1 square foot is occupied by adult cannabis. Hence, a flowering of P900 can be 12-24 at a time.

We have to admit that this light can be expensive. Although just like P1200 LED drivers, it can be used anywhere you may be in the world. A 110V or 220 V input is allowed with 90 days money back guarantee on top of its 5 years warranty.

It can be used as a replacement of a light panel that has 400W HPS light and requires only 180 watts energy consumption.  It’s energy efficient and a good replacement for traditional lights. It is perfect for a small home grower’s use.

If P600 is the higher end type of LED grower light, Platinum Series 300 is also a serious equipment and definitely a steal, considering the coverage it can reach. You can still use this in bigger areas as long as you have additional small lamps with it.

Advanced Platinum Series 300 comes with great high PAR in every lumen of LED grow light panel’s output. Meaning, its panels can emit 2-3 times more intense than that of other grow lights. The best part of this is its 11 band spectrum that offers marijuana plants with the best nutritional value they can get. These include essential nutrients coming from IR and UV. It is also equipped with light chips with 3W LEDs. The 3-watt panels, on the other hand, can focus the light better with its additional lens. The panel is composed of a 60-degree lens and the secondary 90-degree focusing lens for a more intensified plant growth.

Another good features of the lamp are the replaceable chips, which makes it more expensive. Hence, in case a chip blows, you can still keep the 400-watt output.

FAQ on LED Grow Lights


What’s a LED Grow Light?

LED is an acronym for “light emitting diode”. This is intended to help indoor plants grow well, despite the absence of the natural light from the sun. This type of light is designed with many wavelengths, consisting of visible and invisible lights such as UV and IR rays. This light directly acts on the plant to increase its growth and yield.

How does it work?

Can these tiny lights really help plants grow even without sunlight? Blue lights are absorbed more by plants compared to other colors such as green. This means UV rays can trigger plant growth. On the other hand, infrared rays are best to help with blooming and germination.

Grow lights can be adjusted, according to your desired wavelengths. During vegetative phase, UV rays absorption would facilitate cell division. Once cell division will be increased, it will hasten the plant’s growth and result in a better yield.

If you intend to treat your plant and it is in its flowering stage, use lights with infrared rays or “IR”. This will be absorbed by the buds as well as the apex of the plants, resulting to a quick and heavy blooming.

Use grow lights with wide wavelength options. This makes it easier for you to make the necessary adjustments, depending on the effects that the plant needs.

Plant treatment can be affected by many factors including:

  • Wavelength
  • Lumen per area
  • Light
  • Height between plants

Are there any benefits of using LED Grow Lights?

Before LED lights were discovered, there were lights that already existed which serve the same purpose. Among these are the high-pressure sodium lamps as well as the fluorescent bulbs. However, they are not as helpful for small grow room owners who only require tiny compact structure. The lights will require so much space for set-up and proper ventilation must be provided considering the heat that it produced. Hence, small grow room owners opted not to use those lights.

However, with LED light, minimal space is only needed. It doesn’t heat up and will not require bulb replacement. It is devoid of ballast and just consumes half the electricity of other types of lights to run. Here are the benefits of using LED grow lights:

1.  Easy to install and very compact

LED grow lights are built with compact structures. Hence, they are easy to handle. Installing them is pretty straightforward. All you need is to hang the light above the plants at a certain required distance.

2. Can be set adjacent to one another

For more coverage, LED lights can be installed side by side, thanks to its compact structure.

3. Setting up ventilation is no longer needed.

LED lights don’t heat up. Hence, you need not worry about the room’s ventilation system. No need to set up big fans or huge ventilations too.

What about the watts needed for it to operate?

To estimate the needed watts, you need to do some math first. This is done by calculating the area as well as the numbers of plants needing light. If the ratio of the square foot area and the plant is 1:1 then you will need 25 watts per plant per square foot. For a ratio of 2:1 (square foot to plant), you will need 5 watts per square foot, and so on. Hence, for a 250 watts lamp, it can cover around 8-10 plants below it.

Final Words
