Horticultural LED grow lights, also called LED plant lights, emit a very specific range of light that is designed to provide the optimal stimulation to indoor and hydroponic plants and vegetables, ensuring your plants keep growing regardless of the external environment and seasons.
For an indoor grow room or grow tent setup where natural light is compromised, LEG grow lights will keep your plants growing healthy, flowering well and delivering optimal yields.
Here are the best LED grow lights on the market in 2021.
What are the Benefits of LED Grow Lights?
Why use grow lights at all? Here are the benefits:
Low energy cost
LED light bulbs only use about 10% of the energy that regular light bulbs use, so they are very cost effective to run.
This means they are ideal for larger grow tent setups as well as cheap indoor grow setups for anyone concerned about costs.
You can run LED grow lights all day and all night without running the risk of burning the plants or significantly increasing your energy bill.
Because of this, the harvest cycle is not only faster than it would be in an outdoor setting, but it also helps produce a higher, better quality yield due to the consistency of lighting.
Optimized light spectrum
The energy that LED bulb output can be adjusted to specific frequency bands, which means that you won’t be wasting energy in producing light in the wrong area of the spectrum.
This allows you to fine tune the light you are supplying to your plants to best match their growth needs.
LEDs typically last 50,000-100,000 hours, easily 50 times longer than an ordinary incandescent lightbulb. This translates to about 10 years of effective lighting, after which they tend to dim rather than going out.
They are also fully recyclable, which makes them the most environmentally-friendly light bulbs too.
LEDs emit very little heat and are relatively cool to the touch even when running 24/7, so it is easier to control the temperature in your grow tent and there is no risk of the bulbs burning the plants.
Fluorescent lamps and incandescent lamps will interfere with the plant growth. In comparison, incandescent lamps typically produce about 80% more heat than LEDs, potentially harming the plants.
This also means that you save on HVAC costs and can water your plants less frequently.
The best grow lights allow you to control the amount of light the bulb emits, the lighting schedule and even the color spectrum of the light.
This allows you to tailor your lighting to a specific plant type and harvest schedule with ease.
LEDs are compact grow lights, so you can easily set them up even in a smaller grow tent or room without creating clutter.
There are also LED lights that can be chained together, which will help in eliminating extra wiring.
What is PAR and Why Does It Matter?
PAR, or Photosynthetically Active Radiation, is the type of light emitted by grow bulbs. These bulbs are designed to mimic the qualities of sunlight, which plants use in the process of photosynthesis and growth.
Regular light bulbs produce very little PAR in comparison to LED grow lights.
Are LEDs as Good as HPS?
LEDs are the better choice in every way. They produce just as much light while using a fraction of the energy and producing far less heat.
This means that you save on lighting costs and you don’t have to worry about ventilation and airflow systems.
LED grow lights are also more effective at delivering the full spectrum of light, supporting your plants through all stages of growth.
What are the Best LED Grow Lights?
The best LED grow lights offer full spectrum white light (all colors, visible and invisible are represented), are exceptionally energy efficient and eco-friendly, have inbuilt cooling technology and features that make installation easy.
Other features to look for include dimming capabilities, reflective hoods and the ability to link sets of lights together for larger grow spaces.
How To Choose The Best Grow Light
Different plants have different lighting needs and respond differently as light waves change, so you want to do some research on what the plants you’ll be growing need to thrive.
Marijuana, for example, needs PAR (Photosynthetically Active Radiation) values for blues within a range of 440-470nm and reds between 640-660nm.
Choose an LED chip that offers 3W or more, as less simply won’t give your plants enough stimulation for optimal growth. 3 W chips also offer the best quality in terms of white, red and blue light.
This is very helpful in managing the type of light that your plants need. For instance, you can match the output spectrum to summer time or the season of flowering.
If your LED has an adjustable output, then you can help stimulate the light changes to ensure that it matches the plant’s growing cycle.
A good quality LED grow bulb will cost more in the short-term but deliver great long-term results. Look for products that have been built out of durable materials that won’t get damaged easily.
A good indication of quality is a 5-10 year warranty and a guarantee longer than one year on parts.
While LEDs run significantly cooler than other types of lightbulbs, they do create some heat behind the bulb, especially if you are running them 24/7.
Good quality grow lights will have a thick aluminum heat sink attached to the back of the bulb to keep the heat away from the chip. Multi-fin heat sinks are the best option for grow setups and plants that need a lot of heat to grow.
The lens on a grow lamp works to magnify and intensify the light emitted by the bulb, which can improve light wave penetration for your plants by as much as 25%.
Constant driver circuit
The best LED grow lights have an electronic circuit, which will help power the LED lights. The role of the circuit is to help transform the power of AC to direct current within the current level and proper voltage that your LED can handle.
An appropriate circuit should be able to provide a consistent supply of the intensity to be regulated based on the changes of temperature.
LED with an MCPCB (Metal Core Printed Circuit Board) is an essential component for your LEDs, especially if you need higher levels of power for your plants.
It allows your LED lights to operate at higher temperatures without degrading, so it’s a very useful feature for growing hothouse plants.
Did you know – If you live in an area with limited daylight hours, or a home that doesn’t get a lot of natural light, exposing your indoor plants to an LED grow light will help ensure healthy, vibrant growth by aiding in the process of photosynthesis.
Another advantage is that it will help you control the light needed by your plants, so you don’t overdo it and burn more sensitive plants.
Interesting Facts About LED Grow Lights
Here’s some more useful information about LED grow lights that will help you with your indoor gardening projects.
Plant Growth Results
These lights enable you to stimulate the growth of many different plant varieties that you can grow indoors or in a grow tent setup.
This includes peppers, tomatoes, roses, cilantro, basil, thyme, and even medical herbs like marijuana. It also helps you control how the plants grow by changing the light spectrum and exposure.
For example, blue lights can help with the production of sturdier seedlings and control trailing or sprawling, while having the grow lights on 24/7 can also speed up growth and make multiple harvests through the year possible.
Increases Plant Growth
Whether you decide to use grow lights, the growth rate of your plants will drastically increase. This is because the process of photosynthesis in plants takes place consistently throughout the day and night, and is not affected by cloudy weather or even seasonal changes.
This helps to boost growth without stressing the plants.
Red grow lights are important for flowering and fruiting plants, as well as supporting plant development in the early stages of germination, helping to grow strong roots and bulbs.
If a plant is not flowering or fruiting even though it is in a good grow tent setup or near a sunny window, it likely isn’t getting enough light from the red spectrum (windows, heavy weather conditions and pollution can sometimes filter this out).
Setting LED grow lights to the blue spectrum has a significant impact on chlorophyll production, so it boosts the healthy, strong growth of stems and leaves.
If your plants are spindly and leggy or the leaves are paler than they should be, the plant is likely not getting enough blue light. These lights have a lot of applicability and they serve as the best alternatives for plant growth without much sunlight.
LED grow lights come in different options and designs; you should choose the one that best fits your plant growing needs accordingly.
Above are all the advantages of using LED grow lights that you will inevitably experience once you purchase the one that you will use for your indoor gardening.
Now that you already know how to choose one and the advantages that you can reap out of them, then knowing the best LED grow lights available today is essential.
