The Best LED Grow Lights for Achieving Maximum Yield (2021 Edition)

There are various options for indoor garden lighting, but no others offer the energy efficiency and overall benefits to plant growth that LED grow lights can offer. LED lighting wasn’t a viable option for indoor gardening until after 2014, when scientists finally developed a blue-spectrum LED. Until then indoor growers traditionally relied on two types of HID bulbs, High-Pressure Sodium (HPS) and Metal Halide (MH), which offered the necessary light for flowering and vegetative growth, respectively.

Best LED Grow Light were a game changing breakthrough.

Full-spectrum LED grow lights have quickly become an industry standard for both the hydroponic hobbyist and the seasoned commercial growers.

To understand how LED grow lights work, you essentially need to see these grow lights as semiconductors that allow the passage of electricity through a circuit. To further simplify it, there is a small piece of silicon with a Positive side and a Negative side to it and between the two sides there’s a small gap. When electric current is passed through the circuit, electrons tend to jump between the two sides – thereby resulting in producing light. This is the simplest explanation as to how LED grow lights work by converting electric current into light.

The most basic thing that one needs to know about growing weed is that it requires some basic elements of nature – air, water, heat, and light! While all four of these are available in the outdoor growing setup and exist freely in nature, the problem with growing weed outdoors is that it does not allow the grower to have any control over these factors. Basically, there might be a day where the sun might be behind the clouds – which means that both light and heat are being cut off – and there might be multiple such days. Furthermore, there might be a dry spell for a really long time and water might become scarce!

Hence, it is essential for any good ‘grower’ of weed to grow their cannabis indoors and under controlled environment which would ensure that they can emulate a ‘best-case scenario’ for their plants by providing heat and light with the help of grow lamps and air and water can also be provided in just the right amount!

Grow lights, in particular, are the most important because essentially what they are doing is that they are emulating the natural light and heat that the sun provides to the plants. Plants need light and heat because they use that to create pigments and energy with processes such as photosynthesis. This is what helps them grow stronger and healthier. Furthermore, especially for cannabis plants, grow lights are of another importance – based on the kind of heat and light you provide at different stages you can somewhat alter the chemical composition of the plants getting a stronger or a lighter flavor in the weed that you are going to smoke! Hence, it is essential to know about grow lights and understand their functions.

LED grow lights are growing lights that are made out of the light emitting diodes (LEDs) with varying wavelengths (colors). It has been scientifically proven that LED’s different colors help the plant cultivation in its various stages: from growing to fruition. We are here to see which LED grow lights are the best for growing cannabis.

Whatever your intentions are for buying a LED grow light, you must be aware of a fact that not all LED grow lights are the same and that you must choose a grow light that would satisfy your needs as a grower. Pick a good one and you will have a high time of your life. We have assembled a small list of things to consider before buying the best LED grow light for the money.

• How to choose the best LED grow light: It all depends on your needs and your budget. If it’s a small scale operation, you may be satisfied with the ones that are more affordable and less wasteful. If you are growing for commercial purposes, you need a quality and durable LED grows light used in professional settings for your business venture.


• Different spectrums for different cycles: A full-cycle LED grow lamp is required if you want to grow your plant from seedling to flower. On the other hand, if your plant has already germinated in outdoors conditions, you may only require LED grow lights in the blue and red spectrum for growing and flowering respectively.


• Mind your budget: Just like any other type of product on the market, there are products that are pricey and products that are more affordable. Planning is crucial at this point. A grow light is not the only part of an indoor growing operation: there are also filters, fertilizers, nutrients, soil and many other components that you will need to spend your money on. Plan carefully and find one that fits both your requirements and your budget.


• What do your plants need: Check your plants’ needs. Some plants require full or high light while others need low light. If your plant is sensitive to strong lights it is senseless to waste your money on a LED grow light that would dry out or burn your plants.

For your plants to bud as best as possible, you need to pay careful attention to how much light they’re getting during certain parts of their development, as well as how much darkness they’re getting.

You’re not only trying to replicate natural day, but also natural night.

Seedlings and clones require the most amount of light to get started

Sometimes, 24 hours of light is completely suitable for these stages of the plant.

The important thing is that you’re providing no more than six hours of darkness for these plants that are really depending on the light to get strong.

Plants in the vegetative stage will require 18 hours of light to reach their fullest potential.

The six hours of darkness they receive is vital in giving them a break. This darkness is like their sleep, and it’s helping them store their energy appropriately.

Overtaxing your plants can cause premature death before you even reach the flowering stage.

It’s very important you let them have their rest.

During the flowering stage, energy conservation is the most important. It takes a lot of your plant to produce a healthy bud, and they’ll need to rest for an amount of time equal to their growth.

A good rule here is to divide the light cycle directly in half. One hour of rest for every hour of growth is crucial, so 12 light hours and 12 dark hours will give you the best result.

We hope that by reading this article you have gained an insight into all the basics of growing marijuana as well as obtained a better understanding of all that needs to be taken care of while buying an LED grow light. Grow lights are very important for the well being of your marijuana, or any plant for that matter. They replicate the light of the sun and thereby help the plants in growing towards their direction and also help in generation of energy via photosynthesis.
