What Color Light Is Best for Succulents?

Succulents are adaptable as they strive well inside as well as outside. But, they might not have as much sunlight as they could have indoors. The good news is that you can bring in some light for your plants!

What color light is best for succulents, though?

You can opt for red light if you want them to bloom or blue if you want them to grow big. Combining the two is a good option, too. Just keep in mind to always provide them with full-spectrum light that mimics sunlight.

In this article, we’ll dive deeper into how the color, direction, and amount of lighting can affect the growth of your succulents.

How Inadequate Light Can Negatively Impact Succulents

Your succulents can withstand the wrong kind of light for a time. If they experience this for too long, their growth rate and health can be greatly affected.

If your succulents aren’t getting the right color or amount of lighting they need, they’ll show the following signs.

  1. Their leaves appear to droop.
  2. Their colors start to fade.
  3. Their rosettes lose their shape.
  4. Their stems begin to stretch.

The Best Color Light for Succulents

Here are the perfect light colors to use for your pretty succulents!

Red Light

Red light is the warmest color that succulents love. It falls under wavelengths of 620 to 750 nanometers, give or take.

This light color is preferred when you want to help your indoor plants bloom. It aids in fruit production as well.

Blue Light

On the cooler side, blue light is another friend of a succulent. It’s on the other side of the spectrum, falling under 450 to 495 nanometers.

Instead of the growth of the plant’s flowers, this light helps the whole succulent be bigger, stronger, and healthier.

Purple Light

Purple is halfway between blue and red on the color spectrum. Purple light is a mix of red and blue light. Its wavelength is around 380 to 400 nanometers.

For succulents, it gives the benefits of both blue and red light.

Full-spectrum Light

White light encompasses all colors of the rainbow, but the color only appears white to us. The best color light for your succulents is bright, full-spectrum light in all its glory.

This is because it mimics the light of the sun.

You’ll get the benefits of the whole color wheel without straining your eyes.

The Best Light Temperature for Succulents

Of course, the warmth or coolness of light is determined by the light’s temperature. For those who aren’t familiar, this degree of a light’s color is measured in Kelvins.

The lower that value is, the warmer your light should be, and vice versa. So, if you’re ready to buy artificial lights for your succulents, looking at the light source’s temperature should help you make up your mind.

Ideally, the light source should have a temperature of 3,000K to 6,000K to act as full-spectrum light for your succulents.

For red light sources, your best bet is to go for 2,200K. On the other hand, blue lights come at 7,500K.

What Other Factors to Consider When Shopping for a Succulent Grow Light?

Here are some other considerations you should keep in mind besides light temperature and color when buying grow lights for your succulents:

The Output of the Light

The light output entails how powerful the visible light is through lumens. Brighter lights have a higher rating in lumens.

You can mimic daylight through the output of the artificial light source. It should be 2,300 to 9,300 lumens per square foot.

The Wattage of the Light Bulb

Watts measures how much electricity is used in operating your light. So, if your light source balances high wattage and lumens, this means it’s more energy-efficient.

Therefore, it’s always a good idea to aim for higher lumens per watt values for your grow lights to increase their longevity.

Types of Grow Lights

Grow lights come in all shapes, sizes, and capacities. When looking to buy a new grow light, you should first know what types are available on the market, and what size is right for you.

Here are a few options to consider:

HID (High-intensity Discharge) Lighting

Let’s start with the most expensive out of all the lighting fixtures for indoor plants.

HID lights are best for commercial use as they’re bigger. You can use them if you have a large collection of succulents at home.

This industrial-sized light source is a really powerful bulb since it’s made to produce a massive amount of light. This will indeed put a damper on your electric bill!

LED (Light Emitting Diode) Lighting

LEDs are not as expensive as HID lights, and they’re better options for red or blue lights instead of high-intensity, full-spectrum lights.

LEDs can give off a particular wavelength to release either blue or red light or a mixture of both.

Because you can adjust these light sources to give off certain wavelengths, they won’t consume as much energy as HID lights either. Therefore, using LEDs won’t hurt your bills as much!

Fluorescent Lighting

Now, here’s the favorite of all succulents. These lights come in tubes, like the ever-popular T5 that can hover over the room.

You can also get CFL (Compact Fluorescent Light) if the former is too big for your space. These are placed on a round base, perfect for a table or desk.

Fluorescent lights are the lighting source that is capable of bringing your plants the entire spectrum of light.

However, you should be cautious when using CFLs. They give off so much heat, so be wary about placing your plants near them.

Tips to Consider When Using Grow Lights for Succulents

Now that you know which light colors to use and all the other factors to consider before buying them for your plants, it only makes sense to understand how best to utilize grow lights for succulents.

The following tips should have your back in this regard!

  • Don’t place the light near any water source to avoid risks associated with electrocution
  • Place the plants around 3 to 6 inches away from the light source to avoid overheating.
  • Keep up the watering schedule, basing the time on the appropriate season, to encourage growth.
  • Don’t keep the grow light on for more than 12 to 14 hours.
  • Let your plants stay in darkness for the remaining hours of the day.
  • Keep your grow lights on for a longer time during the summer to mimic the cycle of the sun outdoors.
  • Make sure to turn your lights off for a longer time in winter for the same reason.
  • Research exactly how much light your specific type of succulent needs so that you can tailor its light exposure to its requirements seamlessly.

Wrap-Up: What Color Light Is Best for Succulents?

Your succulents can be great indoor plants as they combine a cute appearance with a no-hassle care schedule. Nevertheless, knowing what color light is best for succulents is a must to grow happy and healthy plants.

The best light color is indirect full-spectrum light—a color temperature ranging from 3,000K to 4,000K. To focus on growing flowers or increasing the plant’s growth rate, red light and blue light will help you out here.

The strength of the light should be 2,300 to 9,300 lumens per square foot.

Additionally, you need to consider the output, wattage, and type of light source. Here, you can aim for HID lights, LEDs, or CFLs.
