Best LED Grow Lights

Table of Contents

If you’re looking for the best LED grow light for your grow room, this extensive review will help you make the right choice. Whether you will be growing vegetables, flowers, or even cannabis, the right grow light can make all the difference.

With so many LED grow lights on the market, choosing the best LED grow light can be difficult. Especially with so many variables from grow space, to the types of plants you wish to grow, this article is designed to help you pick out the top grow light based on your unique growing situation.

LED Light Considerations

grow light considerations

Choosing the perfect LED grow light for your grow space means you need to have some important things in mind. The following are some of the most important things you should keep in mind when choosing an LED grow light:

  • The area you need to cover: The first thing that you should keep in mind is the area that needs to be covered. By knowing this, you can decide how many LED lights you will need, and which type of LED will provide you with the best coverage. Keep in mind that 5000 lumens are equivalent to about 50-80 watts; an LED grow light that has a power of about 250 watts and should be covering about a 5-6 sq. ft. area. In order to cover more space, more lights can be placed adjacent to each other. For most grow rooms, this also assumes 1 sq. ft. for one plant. Depending on your space, you don’t always need the most powerful LED grow light, instead focusing on light intensity.

  • The phases of the plant growth you need to treat: You also have to know the growth phase of the plant you need to treat or enhance. If you need a full growth cycle using these LED plant lights, you should select a full spectrum LED grow light to assist in all phases with different wavelengths at your control. It’s preferred that you have UV and IR in the selected grow light. Some are good for both the flowering and veg stages as they can match natural light.

  • Variety of light wavelengths you want to have: When it comes to the best LED grow lights, keep in mind which wavelengths you would need to use in your grow area and focus on having them in your selected LED setup. There are full-spectrum grow lights on the market that will cater to anyone, but they will be more expensive than those with a shorter range.

  • Type of plants: Different plants have different needs, and you should select a grow light that caters to the needs of your plant. Lettuce, for example, will have different needs than cannabis, which will have different needs than tomatoes or flowers.

  • The angle of the LED lens: Also look for the angle of dispersion within the LED bulbs. The greater angles mean more coverage while the lesser angles mean less dispersion. A lower value means better targeting, and a higher angle value means more dispersion and less targeted supply of light toward the plant.

  • Your budget: While it would be great if you could get a top-quality full spectrum LED grow light for cheap, this is not a realistic expectation. You will have to factor in the features that are necessary for you and the amount of money you are willing to spend. The good news is that in this day and age, the tech for these lights has improved, and even the cheap grow lights offer an advantage over traditional fluorescent bulbs. If you have to go with a cheap grow light, then stick with a full spectrum efficient LED grow light. It will have everything you need to grow healthy plants.

The Mars Hydro TSL2000  is another high-end grow light choice for those who have the budget to afford it.

The Mars Hydro doesn’t come with any instructions so it is intended for the more advanced growers. We noticed some slight singing when we used the “flower” setting, but there were no such problems with the “veg” setting – one of the perks of an adjustable spectrum.

Those with other lights in consideration will probably prefer to use this one as a backup light, but it definitely excels when compared to less expensive options.

Unlike our P600 and P300 which allow different settings for flowering and vegetative stages, you can’t adjust anything on this light – it stays constant and you will have to control it carefully with a timer.

Apollo Horticulture 300W LED Grow Light

We’re no strangers to Apollo Horticulture, so it should come as no surprise that we also reviewed their energy-efficient 300W LED Grow Light for our master list.

This small LED light (roughly the face dimensions of a sheet of paper) gives off a substantial amount of light for its compact size. The panel gives off a wide spectrum of wavelengths, ensuring that every phase of your plant’s life is covered.

LED Grow Lights Q&A

Whether you are new to growing or one with seasoned experience, it doesn’t make a difference – you want quality when it comes to the best grow lights.

That’s where 420ProGuide.com comes in – We are here to share what we have tested in the led grow lights niche and answer all your burning questions about grow lights.

What is an LED Grow Light?

Let’s start with a little intro about “LED Grow light”

If we separate the three components of this little bunch of words, we get:

  • LED: that stands for light emitting diode

  • Grow: it helps plants to grow best when they have been planted indoors

It provides various wavelengths of light including UV and IR rays that can directly increase the growth and hence the yield of any plant grown under these lights.

Every grower has his or her own experiences and if he/she has found success then you should know what the secrets are behind the success.

We strive to share tips, tricks, and secrets about what we have learned, earned, and grown, during our 10 years of indoor plant-growing experience.

The role of LED grow lights in our grow rooms is pivotal and we must say that without these tiny LED fixture lights we might have not succeeded as much as we have.

How Do LED Grow Lights Work?

Now, if you still have questions about how the best LED grow lights can help your plants grow better when there is no sunlight, we are here to answer these queries as well. The answer is simple.

When the plants are placed under the LED grow lights, the lights emit a certain amount of photons to the surrounding area.

These photons are emitted in the form of rays toward plants, having various wavelengths.  Plants absorb these rays and these rays activate the cell division among the plants.

The wavelengths can be adjusted according to the requirements of your plants in the grow room. Think red and blue wavelengths for example.

Each wavelength provides different types of energy the plants need during different plant stages of growth.

If you have plants to grow that are in their vegetative phase, using UV rays would increase cell division when the plants absorb the rays. Due to the increase in cell division, the plants grow quickly and result in more yield. White LEDs and blue LEDs are crucial in the vegetative phase.

In case you need to treat your plant in the flowering stage, the most effective LED lights are those which provide IR rays. Infrared rays are best to enhance the bloom stage of the plants.

We would recommend an LED grow light that has a wide range of wavelength options available so that you can adjust according to the effects that you need.

The amount of light, type of light emitted, types of plants being grown, Lumen per area, wavelength, and the height between plants and the light can all affect the growth of the plant being treated.

Good LED grow lights should include all spectrums that enhance plant growth.

What Are the Benefits of Using LED Grow Lights?

According to my knowledge, before the rise of these LED grow lights, there were other similar methods in use.

These include HPS methods and fluorescent bulbs. These methods were not at all favorable for small grow room owners who need to have a small, compact structure to assist them in their indoor plantation venture.

This mess made that process out of reach for the small grow room owners.

Now if you can see what we have by using these LED grow lights, it can clearly be noticed that these lights have made each and every grower either a hobbyist or a professional, able to grow enough indoor plants using LED lights at their ease.

If you need to know what benefits can you get using them here are my experiences:

  1. Can be installed adjacent to each other: As said earlier they have a compact design and most of them can be installed adjacent to each other in order to give more coverage.

All these factors have made me a great fan of these LED grow lights because you have complete control over what you need to get through them.

How Many Watts Do You Need to Grow Indoors?

In order to know the exact wattage you should have in your grow area, you should first calculate the area and the number of plants you will need to cover.

If we consider that 1 sq. ft. has 1 plant potted in it, then, the recommended wattage is 25 watts per plant per square foot.

If you have two plants in one sq. ft., then the recommended wattage per square ft. would be 50 watts, and so on.

So, if we consider our example discussed earlier, we have an LED grow light having a total wattage of 250 watts; it would be best for 8-10 plants to grow under it.
