Are Led Lights Good For Hydroponics?

Yes, LED lights are a great way to go for hydroponics. They have many benefits over traditional fluorescent bulbs, including:

  • Higher lumens per watt (the amount of light produced per unit of energy) – LEDs are more efficient than fluorescents and use less electricity
  • Longer life expectancy – LEDs last up to 10 times as long as fluorescents, so they won’t burn out on you mid-grow
  • More flexible spectrum – LEDs are available in different wavelengths that can be used for specific applications like flowering or vegetative growth stages

How Do You Use Led Lights For Hydroponics?

If you have decided to use led lights for hydroponics, then there are some things that you need to know. 

First of all, the first thing that you should do before installing led lights is to check your current setup and make sure that it can support the new system. 

You will also want to determine how much wattage of led lights that your current system needs so that way when you install leds, you know what kind of wattage bulb will be best suited for them.

Are Led Light Bulbs Better Than Fluorescent Bulbs For Indoor Gardening?

If you want to make the best use of your indoor gardening space, look no further than LED lights. They are brighter than fluorescent bulbs and use less power than other types of bulbs. 

These are two benefits that will give you more bang for your buck when it comes to growing plants indoors.

LEDs also last longer than other types of bulbs. The average lifespan for a fluorescent bulb is 15,000 hours; meanwhile LEDs can last up to 50,000 hours before they need replacing. 

Those extra years in between replacements mean that you’ll be able to save money on replacement costs over time by using LEDs instead of other types of lighting systems in your indoor garden area at home or work!

How Far Are Led Grow Lights From Plants?

The most important thing to know about Led lights is that they can be placed very close to the plants, which means you’re getting more light per watt of energy than with other types of lighting. 

That’s because LED grow lights are more efficient than fluorescent or HID (high intensity discharge) lighting systems used in growing your plants.

In addition, LED lights last longer than other types of bulbs and tubes because their technology allows for a higher degree of durability and less overheating problems when compared to traditional fluorescent lights used in hydroponics applications.

What Is The Difference Between Led Lights And Other Lighting Systems?

As you can see, there are many reasons why led lights work well with hydroponic systems. They are more efficient than other types of lighting and they last longer as well. 

If you want to get the most out of your indoor garden then it is recommended that you invest in led grow lights instead of other types of light bulbs or fixtures. 

Another great thing about using led grow lights is that they don’t put off harmful radiation like fluorescent bulbs do, which makes them safer for people who live in close proximity to them (like children)

Do Led Lights Work In Hydro?

As you may have guessed, the answer is yes LEDs can be used in hydroponic systems. In fact, they’re a lot of people’s first choice when it comes to growing plants indoors. 

Why? They’re more energy efficient and last longer than fluorescent or incandescent grow lights. They also don’t emit heat like incandescent bulbs do, which means less wasted energy on cooling systems and/or ventilation requirements!

But before you run out and buy some LEDs for your next grow op project, here are a few things to keep in mind:

“Selecting the right hydroponic nutrients is one of the most critical considerations for hydroponic gardening success. Our guide includes a list of excellent hydroponic nutrients and explains what to look for when selecting nutrients for your plants.”

Will Led Lights Work On My System?

While it’s true that LED lights are more energy efficient than other types of lighting, the answer to whether or not they will work on your system depends largely on the type of LED light you choose and how many watts it uses. 

It also depends on the size of your hydroponic system, as well as its wattage requirements.

If you want to use LED grow lights in your indoor garden, then we suggest using ones that have a rating of at least 20 watts per square foot (for example: if your space is 10 square feet, then look for a 60 watt or higher rated product). 

Using less than this might result in plants being under-lit and not growing as fast or hardy as they normally would when exposed to higher levels of light intensity.

How Can I Tell If My Hydroponic System Needs More Wattage Of Leds?

To determine if you need more wattage, place your plants under the lights and measure how many hours of light they receive. 

Next, calculate the area of your grow space in square feet (ex: 3′ x 5′ = 15 sq ft) and how high up the plants are hanging from the top of your canopy (in this example we will use 2′). 

Now divide these two numbers together to get an average number of watts per day that a plant is receiving.

Next, compare this number with what you are currently using per day (in this case I have three 400watt bulbs running for 18 hours). 

My average daily usage would be 1.5 watts per day/plant * 15 square feet * 2 inches above canopy = 30 watts/day. This means that my current setup isn’t using enough power to reach its full potential!

Why Should I Use Leds Instead Of Other Types Of Lighting In My Indoor Garden?

  • Led lights are more energy efficient.
  • Led lights last longer than other types of lighting.
  • Led lights are more durable than other types of lighting.
  • Led lights are easier to install than other types of lighting.
  • Led lights are safer than other types of lighting

How Long Do Led Lights Last?

LEDs have a much longer lifespan than other types of lighting. Whereas traditional fluorescent bulbs are estimated to last around 10,000 hours, LED bulbs can last up to 50,000 hours. 

This means that if you were to use a single bulb for 12 hours a day, 365 days per year (assuming weekends off), then it would take at least 13 years before the LED bulb would need replacing with another one!

Because LEDs don’t contain mercury like fluorescent lights do and because they are made from plastic instead of glass like incandescent bulbs do – both common causes for lighbulb failure – this makes them far more durable than any other type of light source.

How Much Energy Do Led Lights Use?

The average power consumption for a standard fluorescent light bulb is about 75 watts, so for every 100 watt equivalent you’ll save about 25% in energy costs. 

The remaining savings come from the fact that LED grow lights have a longer lifespan than other types of lighting systems. 

This means you can use them for many years without having to replace them as often and even if you do have to replace your LED grow lights after a few years, it will still be cheaper than buying new incandescent bulbs or fluorescent tubes every year.

In addition, LEDs are highly efficient in their use of electricity compared to incandescent and fluorescent bulbs which waste most of their energy in heat instead of providing useful light output (the coefficient of utilization).

How Many Led Lights Do I Need For My Hydroponics System?

The number of LED lights you need depends on the size of your grow space. Smaller LED lights are available, which would be good for smaller spaces or those who don’t want to spend too much money on their lighting setup.

You may also find that some LED lights come with adjustable brightness settings or other features that allow you to customize the light intensity in different areas of your grow room. 

If this is important to you, it’s worth looking for these kinds of options when shopping around for new LED lights for your hydroponics system.

What Type Of Led Light Should I Buy For My Hydroponics System?

To get started with led lights for your hydroponics system, you need to consider how much light is needed for the part of the plant that you are growing. The following chart will help you determine how many watts are necessary based on how far away the plant is from the light source:

For example, if you have a 6″ tall rooted clone and want it to grow vertically (with no horizontal branching), then it will require approximately 150 watts per square foot. 

If your goal is to grow several plants together in one container without any vertical growth, then plan on using 200 – 300 watts per square foot or more depending on how close together they will be growing (the closer together they grow, the higher wattage).


In conclusion, led lights are a great choice for hydroponic systems. They are energy efficient and have a long lifespan, which means they can save you money in the long run. 

If you want to keep your plants healthy and happy, then it’s time to invest in some high quality led lights!
