Full Spectrum LED Grow Lights

When you grow weed indoors, you need to recreate a number of different elements which otherwise exist outdoors in nature. These elements include light, heat, air, nutrients, etc. and while all of them are very important, plants need high-quality lighting for better growth. Full-spectrum LED grow lights are among the best possible lighting that you can provide to your plants for good growth. 

Over the course of this article, we shall be taking a detailed look at some of the best full spectrum LED grow lights available in the markets. We shall be reviewing each of these grow lights in detail and provide you with the pros and cons of buying them! However, before we begin any of that, we shall first be taking a closer look at what these full-spectrum LED grow lights are and what is the importance of lighting in the process of growing marijuana. Post that, we shall be looking at the 7 best LED grow light options that you have when looking for full-spectrum lighting solutions, followed by some of the factors you need to consider before you buy LED lights for your plants. Post that, we shall look at some commonly asked questions before we conclude! 

We hope that by the time you reach the end of this article, you will be able to make an informed choice about which grow light is the best suited for the needs of your plants and will help you get the best yield! Let us begin by addressing the basics first:

What is a Full Spectrum LED Grow Light?

Growing your marijuana indoors is considered a better option by many growers because while you do this indoors, you are growing your weed in a controlled environment where you can recreate and tweak all the natural elements so that the plant gets an optimal growth. None of these elements, however, is as important as the light that the plant gets. Ideally, a marijuana plant has to grow under sunlight – however, when you grow it indoors, you do it under a grow light. Full-spectrum LED grow lights are the best options you have when it comes to growing marijuana because the kind of light that comes from them is very similar to the natural light of the sun.

Sunlight appears to us as white or yellow. However, it is actually made up of a spectrum of different lights – and this spectrum has two ends, one being the warm red lighting while the other being the cool blue lighting. Plants, in order to get an ideal growth, require both these types of light across different phases of their growth. During the early stages and vegetative growth, plants require more of blue lighting than red and for the flowering/blooming phase, plants need more of red lighting than blue. 

Getting a regular LED light won’t guarantee that you are getting light from all the different wavelengths and spectrums. Hence, you need to make sure you are getting a full-spectrum LED grow light to ensure your plants get a proper growth. Let us now take a detailed look at some benefits of using grow lights, followed by the 7 best lights that you can get in the markets. 

Benefits of using Grow Lights for Growing Marijuana

There are a number of benefits of using LED grow lights for growing marijuana. However, the first and the biggest benefit that you get is that they are much more energy efficient when you compare them with older and traditional forms of lighting. Basically, they consume less power from the socket while offering you lighting which is equivalent to a higher wattage output, allowing you to save a lot on the electricity costs. In addition to that, the lifespan of LED grow lights is much longer (average of about 100,000 hours) when you compare it with older types of grow lights. 

LED grow lights also provide you with full-spectrum lighting solutions in just one panel – and you don’t have to change your lighting setup once your plants mature into the flowering stage. Another huge benefit of using LED grow lights is that they do not heat up as much as some of the previous lighting options such as HPS lamps and Metal Halides. They are also free of any toxic elements and can be easily disposed after their lifespan has expired. Hence, LED grow lights offer a large number of benefits and are the preferred form of lighting for growing weed indoors.

7. Phlizon Newest 600W LED Plant Grow Light

No products found.

A relatively lesser-known brand in this list, Phlizon has also been around for a while and is particularly known for their inexpensive and cheap LED grow lights. This is a 600W LED grow light from the company. However, there are also 900W and 1200W variants if you wish to buy them. This one costs around $85 and is one of the cheapest and the most basic options you’ve got in the markets. This is a product for entry level growers who are just learning and don’t really want to spend too much or for someone who is looking to buy a backup LED grow light. 

However, getting a full-spectrum grow light at this price point is indeed a great deal. There are separate switches for the VEG and BLOOM mode which will make sure you can provide your plants with a great growing experience during each phase of their growth. You also get IR and UV lights in this panel. However, the coverage area here is really small. You only get about 2×2 ft of coverage and will probably need multiple such lights for even a 4×4 tent. 

The lifespan of this grow light is 50,000 hours, which is OK considering the extremely low price it comes in at. While it offers a 600W output, the actual power draw is about 100W (with a variance of about 3%). Fireproofing has also been covered here and this device is extremely safe to use. There are 60LEDs of 10W each in this grow light panel.

Buyer’s Guide: What To Look For in an LED Grow Light?

Now that you know which are the seven best options that you have when it comes to buying an LED grow light for growing marijuana indoors, you need to look out for some of these factors that have to be considered when you buy the light:

  • Coverage – You must make sure that the light you are buying is big enough to cover the number of plants that you have. If the light isn’t big enough you might even consider buying multiple panels of the light which can then be placed inside the same grow tent to cover a larger area. You must know how your plants are placed and how much space they occupy in order to know what grow light will suit your needs.
  • Electricity Consumption – You must check two things – the wattage as well as the electricity consumption. The simplest way to understand this is that ‘wattage’ means the amount of light output you’d be getting and the electric consumption is – how much electricity will it be consuming from the wall socket. Thankfully in case of LED grow lights the electricity consumption is always lower when you compare it to the wattage. However, you must still need to check how much electricity your grow light consumes before you buy it.
  • PAR ScorePAR score, in very simple terms, is the amount of light that is absorbed by the plants from when it leaves the grow light. The simplest way to understand this is – the higher your PAR score, the better it is. Getting grow lights with a higher PAR score will mean it will help your plants grow bigger and faster and ensure higher yields compared to grow lights with lower PAR scores.
  • Quality of LEDsQuality of the LED lights matters a lot. Check the reviews to see if they are saying anything about the quality of the LEDs attached to the panel. Sometimes, in poor quality grow lights some LEDs stop functioning after a while and there are blind spots on your grow light. In our list, we have ensured that no such grow lights are included. However this is something that you must know! Getting a full spectrum LED grow light which provides dimmable LED lights is always a good option for indoor marijuana growers.
  • DurabilityYour grow lights also need to be durable. In case of any bumps, falls or the odd event of the grow tent collapsing, the grow light must not be affected and it must continue to function. You must also look for a grow light which is waterproof or water resistant. Since you work with a lot of water while growing plants, this is something that needs to be taken care of.
  • CoolingLED grow lights don’t emit a lot of heat compared to older forms of lighting but you still need to ensure that your grow light has enough fans and vents to ensure that heat does not accumulate inside it and damage the light. An ideal grow light has multiple fans and openings to dissipate the heat.
  • Lifespan, Warranty, and CostThese are three of the last factors on our list but they must never be the least on your priorities! Always check what lifespan the company is promising, see the reviews if it lives up to the promise. Moreover, the longer the warranty period the better it is for you! Lastly, cost must also be a factor. Set up a budget and make sure that you are sticking to it when it comes to buying the grow light of your choice.
