Best Led Grow Lights Buying Guide for Growing Vegetables & Cannabis

Posted by

Are you looking for a way to grow vegetables or cannabis indoors? The perfect solution is to make use of technology. The best grow lights are LED. It saves energy as it brings the right light frequency to your greens. Your plants will love the opportunity to get the right lightning.

There are advantages of using led grow lights for growing greens. Most of all you can calculate the exact amount of light they need. When they are exposed to sunlight it can be too much. Harvesting inside with artificial lightning is an excellent way to achieve your production goals.

02. What is Led Grow Light

LED is a technology that has been around for some time. It comes from a type of semiconductor that emits light. In fact, LED is the acronym of Light Emitting Diode. This sort of technology has raised as a popular source of light in the past couple of decades.

As for led grow light specifically, it is an arrangement of LEDs that comes in a squared or rectangle package. It is usually set to cover few square meters. You should place it on top of your harvest so that it replaces the light that would come from the sun.

The kind of light a led grow light arrangement provides is not the same you would use to illuminate a regular room at home. It is specifically designed to increase the performance of your greens. This means the plants will grow faster than with other source of light.

03. Benefits of LED Grow Light

In general, there are many advantages of using led lights. But when it comes to led grow light the benefits boost to the sky. They are specially designed to address the vegetables’ needs. With a LED, you can fine tune the frequencies from the hardware itself, and therefore increase your production goals.

When it comes to LED as a technology, there is an important power saving factor to consider. This is something you must put on the table, as most harvests require extensive consumption of energy. In the end, the power consumption of your grow lights will add up dollars to your electricity bill. By getting led grow lights you will be saving money.

Besides, not all lights are created equal. Greens require specific frequencies to grow strong and healthy. It is the sort of frequency that promotes its growth that comes packed in a led grow light. Other harmful frequencies are omitted, so that only the good thing of light is left.

In addition, the led grow light is meant to provide light with minimum heat to your indoor plants. This is particularly important, as you will hardly over expose your greens to heat. Therefore, there are no chances of burning them, not even by accident.

Cannabis in particular is not too fond of excessive light. It prefers to grow in the shadow, but it does require certain amount of light to grow. There is where grow lights fit in. By giving it artificial lightning, you ensure you are in control. There are few external factors that can mess up with your plants. A led grow light is better than other options because you get the best heat control with it. With artificial lightning you are in control. You could even automate the lights to get the best possible performance.

04. Features of Best led grow lights

The best led grow lights have a place for hangers. These are useful to spread the light efficiently when you place the light on top of your plants. Some packages will include the hangers, while others need you to get them separately.

The most important feature is the light spectrum. The different stages of growing plants require different frequencies. If you are harvesting assorted plants, then chose the artificial light with the most frequencies. Despite most led grow lights are labeled as full range spectrum, that is not always the case. Check how many LED varieties they include. With LED technology, each individual LED is meant to provide a different frequency. When you combine them, you get the full range spectrum that is marketed. However, since there are no standards for this term it has been overused. To learn more check our following section about full spectrum (05.02 What is full spectrum).

Another feature of led grow lights are the fans for cooling. This actually depends on the total power you need for the device. The lowest rated power led grow lights will not need such fans. They usually have heat sinks that get rid of the extra heat the unit may have. If you can avoid getting a led grow light with a fan it is best. That way you will lower your electricity bill and increase the life of your led grow light. A mechanical part is always a risk in any electronic device and you should avoid it. However, when you are harvesting in an extensive area or room, there is no way to avoid having a high power lamp with fans.

05.Few factors you should know

When it comes to LED lights, there are a few factors you should know. They are full of technical jargon that most of us are not used to. Being aware of the techniques is going to give you the true insights to assess each led grow light product.
Next we are going to check on the following concepts:
• Lumen.
• Full spectrum.
• Watts.
In the end, we will help you to calculate how many watts you need for your crops. That way you can be prepared with the appropriate power installation for your harvest.

05.01. What is lumen?

Lumen is a unit to measure the luminous flux. This means that you get an idea of how much light a source is giving you. The more power, the more lumens, but it also depends on the technology you are using.

For example, to get 800 lumens with an incandescent light bulb, you would need 60 watts. With a compact fluorescent, the power consumed drops significantly to around 15 watts. But if you use LED technology, then it can get as low as 8 watts.

In conclusion, lumens help us to compare the actual performance among different lightning technologies.

05.02 What is full spectrum?

Full spectrum is a term used to describe artificial lightning that is capable to emulate sunlight. This natural source of light provides us with frequencies we don’t even see. They include infrared light and frequencies close to the ultraviolet spectrum. All these wavelengths are very important to life growth on earth. They stimulate and enhance certain processes that occur in nature.

When it comes to artificial full spectrum lightning, not all options are created equal. There is no actual regulation when it comes to the amount of light given on each frequency. The difference relies on how the power is distributed. The most important thing with lights is that they provide the right amount of power on the frequencies that matter most for your crops.

In real life, we don’t get the full spectrum all day. It changes depending on the hour of the date. When it comes to artificial lights, there is no such change. This can be a benefit if you use it wisely. Your plants would only take part of the benefits along the day. You can extend these times by giving them an extended dose of the light they need. Just be aware of the limits to improve their performance.

05.03. How can you calculate how many watts do you need?

This calculation depends on which type of plant you growing and in which phase of growth they are. Of course, you also have to consider how many square feet you have planted. To keep it simple we will consider a plantation of 1 square foot on our following examples.

If you were planting cannabis, the most power would be needed during the flowering phase. This means you have to be prepared for it. According to the charts, you would need 64 watts during this stage. This number multiplied by the total square foot of your plantation will result on the total power. Other vegetables with similar power needs are tomatoes and peppers. Practically all vegies that have a flowering stage at some point will have a similar power demand.

Other plants like basil lettuce, other leafy greens, and herbs in general require less power. They are considered low light plants. These plants will need practically half the power than the high light plant types we discussed previously. Consider 32 watts for these plants, which have only seeding and growing phase.

Do not forget to multiply these numbers with the total square footage of your plantation.

06. Top 10 best led grow lights reviews

Now, let’s move on to our recommendations. We have analyzed dozens of lights and came up with this list of the top 10 best led grow lights. We are going to talk about the pros and cons on each, so that you can make an informed decision on your next purchase.

07. Our Recommendation about Best Led Grow Lights

The previous products are all good for harvesting in general. However, when it comes to specific plants, some led grow lights are better than others. Next we are going to bring you some advice on which is the best led grow light for some specific plants.

07.01. Best Led Grow Light for Cannabis

If you want to grow cannabis, we highly recommend you to use the Vintage Grow HIGH YIELD Full Spectrum Hydroponics (Product #3 of our previous section). It is tuned to the frequencies cannabis and other flowering plants need.

Besides, there are different power options that will allow you to plant in small or big spaces. This means that you could enhance the development of a single plant or of a room full of them, just choosing the right power for your needs.

The 12W vintage grow high yield full spectrum hydroponics LED grow light bulb lamp is compatible with any standard socket. You can use any existing spot at home to place this lightbulb.

After using this light, you will notice a significant improvement on the buds of your harvest. They will look bigger and healthier than before.

07.02. Best Led Grow Light for Vegetables

If you are just growing greens, then use the 45W LED Grow Light, UNIFUN New Light Plant Bulbs Plant Growing Bulb for Hydroponic Aquatic Indoor Plants (Product #8). This is a great choice for those who are looking to grow just veggies (no fruits).

This light is enhancing for leafy plants. It has the best frequency choice to promote their growth. In addition, it has a low cost. You pay less for the hardware and for your electricity bill as you can cover a good area with less power than with other products. This is because you don’t need any fans to cool the device.

The UV lights will eradicate any bacteria of your plants. This is important for most herbs. The design is very compact. It is less than 2 inches’ width. It can fit anywhere. One of the great things about this light is that its electrical connection is in the side instead of on the top. This simple change makes it perfect for a place with height restrictions. You can place it right next to the ceiling easily.
The package includes hangers and screws. You will get everything to start harvesting your crops!

08. How can you Care of your Led Grow Light?

Most led grow lights without fans are maintenance free. This is because the LED itself is a very durable device that does not require much. However, we recommend you to add a voltage conditioner in case the zone where you are harvesting has important voltage variations. All electrical equipment is very sensitive to this sort of changes. Preventing damage is the best approach.

Apart from that, you should keep the unit clean at all times. When the led grow light you chose has fans, then it will require a little more attention. A fan is a mechanical part. It can easily get stuck with the accumulation of mud, dust, and other dirt. To avoid this issue, make an extra effort to clean your lamps. Cleaning them once a month should be enough in most cases.

Whenever you identify that a fan is not working as it should, replace it immediately. Most fans included in led grow lights are standard and you should be able to get it easily on, or asking the manufacturer. Do not let your light work without a fan because there is a risk of overheating it. If it does, the LED components may break.

08. Few Items Related to Led Grow Light

One of the essential things on most settings for led grow lights are the hangers. Some products include them. However, that is not always the case. Check before your checkout if the led grow light you chose includes hangers. If it doesn’t and you need them, add them to your shopping cart. That way you will be able to install your led grow lights as soon as they get to your home.

When you chose a light bulb, we recommend you to have a clamp lamp at hand. The lamps with reflectors are best to spread the light source in the best possible way. There are also timers to automate your lightning efforts. Some of the most useful devices are mechanical outlet options. You can easily attach it to your electrical outlet and then plug the led grow lights. That way you don’t need to get to your crops at certain time just to turn on and off the light. There are other timers with programmable cycles which can be useful. If you are willing to spend a few more bucks, then go for this sort of device as it has many more functions.

Another useful device to take care of your plants is an indoor humidity monitor. This device will help you to keep track of humidity and temperature. That way you are going to assess any ventilation needs. Most devices can keep record of the highest and lowest temperatures.

If you find your ambience too humid, then search for a dehumidifier. Another thing you can get to enhance your crops is an indoor Mylar hydroponics grow tent. It is specifically designed to create the right ambience inside your home. You don’t have to make use of a whole room with this product.

09. Conclusion

When you are looking for the best led grow light, you don’t have to get the fanciest device. Do not let manufacturers flash you with elaborate specs. Look for the kind of light that adjust to your harvesting needs. Depending on what plants you are growing, there are affordable products you can get at

When you buy your lights, make sure you have everything for the installation. If not, get the additional things you need. Looking for other aids like timers or humidity monitors is wise. That way you can make your harvesting tasks easier.
