5 Considerations in Choosing LED Grow Light

For the uninitiated, growing cannabis is sure to be an intimidating task. Aside from having fundamental knowledge, you also need to invest in the right equipment, such as those for grow room odor control. However, the most important is perhaps the LED grow light, which will be instrumental in being able to mimic the outdoor environment even in a controlled room. Clueless on which one to choose? Read on and I will share with you some of the things that you have to consider.


Size of the Grow Room


The size of the room where the light will be used is one of the most important considerations. If the grow room is small, you are good with a low-capacity light. On the other hand, if it is big, you will need a light with a more powerful spectrum. You might even need to install several lights. Otherwise, the plants can die because of the inability to receive the necessary light.


Energy Consumption


This is important as it directly impacts the long-term costs of operating a grow room. On average, plants in a grow room will need 12 to 14 hours of light. This will supplement the light that they are not receiving from the sun. Because you need to leave the lights turned on for an extended period, it is important to pick those that do not consume too much energy in the absence of compromising functionality.




Many people might think that the color of the light serves no other purpose except for aesthetics. Truth is, the color is important beyond appearance. Also known as the spectrum, this is going to improve the growth of the plant in different stages. Blue light is effective in promoting vegetative growth. Meanwhile, red light is good for flowering. You might want to replace the lights that you are using depending on the stage of the growth of your plant.


Heat Output


It is also important that the LED grow light does not produce too much heat. One of the dangers of too much heat is that this can affect the temperature in the grow room. Plants can suffer from a number of problems, affecting the buds and the leaves, among others. See to it that the lights have low heat output. At the very least, make sure that the grow room has an effective cooling system.




This is one thing that you should not ignore when shopping for LED lights to use in the grow room. The standard warranty that most manufacturers offer is one year. Look for those with a longer warranty coverage, which means that you can rely on the support from the manufacturer when the product encounters a problem, such as when it becomes defective all of a sudden.


In sum, while there are many LED grow lights that are available on the market, this does not mean that you can buy any product. From the size of the grow room where light is to be used to the amount of energy that it consumes, there are several factors that you have to take into account.
