What Color Grow Light For Succulents

Light for succulent growth

It’s time to set up your grow lights after choosing the best ones for your succulents. Find a location in your home where you can install the lighting and the plants. &nbsp

It’s crucial to leave enough of space between your succulents and the light. If you’re too close, the heat from the bulbs could damage your succulent. If it is too distant, there won’t be enough light for the succulent to develop healthily. In general, it should be at least 6 inches long and no longer than 40 inches. Of course, additional factors affect the precise distance.

A 10-inch spacing is adequate if you use LED or fluorescent lamps without any tricks. However, you can narrow the gap to 6 inches when using larger succulents.

The plant’s tolerance for heat and light also influences the distance. Maintaining the ideal light and temperature for your plants while not wasting any electricity is a tricky balance.

Water inside the cells of the leaves, trunks, and stems may heat up if they are 5 inches or closer from the light. Your plant will eventually become scorched or suffer from dehydration. The following are some fundamental guidelines for using grow lights:

  • It is advised to keep fluorescent tube lights and bulbs 6 to 12 inches away from your succulents. The suggested distance for LED lighting is between 18 and 24 inches.
  • The ideal color temperature for promoting succulent growth is 6500k. A 3000k light is preferable if you want your plant to bloom. Just be cautious if your plant is a monocarpic succulent because it can bloom if you give it too much light.
  • The lights won’t need to be on all the time. Giving your plants a break from the light so they can breathe is good. Generally speaking, expose your plants to light for 12 to 14 hours each day. &nbsp

Don’t let the plants stand with the light source at just one angle. Instead, turn the plants over once a week so that all of their sides receive the same amount of light.

Keep a watch on your succulents when you move them indoors to observe how they respond and make any necessary adjustments. Your indoor succulent plants will be strong and content with the optimum grow light and routine hydration.

Are succulents better off with red or blue light?

Your succulents will benefit greatly from LED grow lights. The light wavelengths that your succulents require to grow and thrive are precisely what they produce. Compared to fluorescent grow lights, they are more energy-efficient and operate more cheaply. They also last a lot longer without losing any light output. Choose LED grow lights if your comfort while viewing is not a priority.

The majority of LED grow lights only emit blue and red light. Strong, wholesome leaves, roots, and stems are produced as a result of the blue light’s promotion of the chlorophyll-development process. Your succulents will remain compact as long as there is blue light present. Red light encourages fruit and flower blooming. It won’t make your succulents bloom out of season, so don’t worry. However, it will improve their capacity to produce and sustain blooms in the spring and summer. The majority of LED grow lights feature more red than blue lights because they are frequently used for growing vegetables or orchids. You can change the output of this LED grow light to produce mostly blue light if you feel the need to do so.

The Lifetimetunnel 45W LED Grow Light Panel, which is an upgraded and better model than the ones I purchased five years ago, is the one pictured above. My succulents and I are satisfied with the outcomes after purchasing three fixtures. For three years, my husband operated these lights nonstop; after that, he did so for around six months each year. There is no light loss, and they continue to function perfectly. Each fixture includes a hanger kit, however depending on your setup, you might wish to extend it. A 15-month warranty is provided. It is currently available at a buy 2 get 1 free price!

Which cultivating lights are ideal for succulents?

Today’s market offers a variety of grow lights, including metal halide (MH), high pressure sodium (HPS), fluorescent, and LED. We will, however, limit our discussion to LEDs and fluorescent grow lights because they are more appropriate for smaller indoor applications (as opposed to medium to large greenhouse installations). These two choices are among the most accessible grow lights and are excellent for succulents.


The most popular option for growing succulents indoors is LED grow lighting. Because LEDs are durable, consume little energy, and operate at low temperatures, growers don’t need to worry about their plants burning up if the light is too close to them. The initial expense of LED grow lights is their main drawback, yet as these lights gain popularity and become more generally available, the relative cost has gradually lowered.

Fluorescent Lights

Compact fluorescent lights (CFLs) and fluorescent tubes are the two main types of fluorescent grow lights. Both can be used successfully for succulents, and your decision will probably depend on how much room you have for your grow light arrangement. Fluorescent lighting is frequently affordable, effective, and adaptable. Growers should be cautious about how close they position fluorescent grow lights to their plants because they do not last as long as LEDs and also tend to run hotter than LEDs. Fluorescent lights are less environmentally friendly to dispose of because they also contain mercury.

Can succulents be grown under a grow light?

The quick answer is that it’s not always a good idea, although it sometimes is. Your succulents will probably make it through the winter with no problems if you have a window that receives bright light all day. There won’t be as much light as there was in the summer, though, as the days get shorter.

Succulents begin to spread out and lose their vibrant colors and compact shape if they don’t receive enough light. They would merely prefer more light, but they are still alive and generally healthy. Succulents frequently extend throughout the winter because of the fewer days.

Keep your succulents vibrant and compact by using a grow light. By doing this, more brilliant light is added during the day. Without a grow light, I’ve kept succulents inside during multiple winters, and they’ve survived. Many of the succulents are seriously stretched by the time spring arrives, but I trim them before planting them outside.

However, I have made the decision that I want to stop my succulents from spreading out this year, so I bought some grow lights.

Which grow light color is ideal?

Although not all grow lights are created equal, they all provide plants with the energy they need to transform light into nourishment. Consider the following categories to gain a better understanding of the variations in grow lights now available on the market.

Light spectrum

Most plants require a variety of colors to survive. Despite the fact that typical grow lights appear clear or white to the unaided eye, they actually emit a variety of colors in varied intensities. This type of light is called “full spectrum.” There are some hues in that spectrum that are particularly beneficial to houseplants.

  • Plants need chlorophyll to flourish, and blue light aids in the production of this pigment. Young plants and seedlings benefit by having more favorable conditions for germination and root growth.

Infrared (780nm-1000nm)

Crops require heat for the growth and development of their roots, which infrared radiation creates. Fruits mature more uniformly when exposed to infrared radiation. This light’s intensity can have an impact on how quickly plant stems grow. Short infrared exposure lengthens the distance between nodes. However, excessive infrared exposure can actually harm plants. due to the fact that infrared light has a high heat output. Plants that haven’t recently received water are especially susceptible to color loss or death from heat. Additionally, too much infrared may have other negative effects on plants, including as stimulating them to flower too early while depleting them of nutrients and living matter, or having them experience premature growth that compromises their health. Plants probably don’t develop the way we want them to in the end.

Far-Red (700nm-780nm)

Including leaf expansion, far-red encourages extension growth. Researchers discovered that leaves will grow larger in the presence of far-red light than in the absence of such light. On the one hand, they grow plants in indoor greenhouses or vertical farms with single-source lighting that can be controlled. On the other hand, as a control group, they supplement the preceding lighting source with some far-red light. Through a similar experiment, they were able to determine how far-red light affects plants. As a result, increasing the amount of far-red in the light spectrum can result in larger leaves. This might expand the region that receives radiation, giving plants a better chance to absorb light and develop. As a result, far-red can inadvertently contribute to longer-term growth. Far red may also hasten the conversion of phytochromes, which shortens the time it takes for plants to enter a dormant condition. Plants are able to yield more as a result.

Red Light (620nm-700nm)

Red light is very good at controlling plant growth and development. Red light promotes blooming, fruiting, and increases flowering time. Plant growth and photosynthesis can both be significantly aided by it. yet, if plants are solely exposed to red light. They’ll appear stretched out and prolonged. Plants grow taller and have long, thin leaves. If this growth trait is not desired, growing under just red light will not be the best option. Regarding the proportion of blue and red light, care must be taken. If done incorrectly, plants’ extension growth is impeded. According to a study, it is preferable for plants to flourish in environments with 80 to 90 percent red light and 10 to 20 percent blue light.

Yellow-Orange (575nm-620nm)

If only yellow light is employed, plants’ capacity for photosynthetic activity is significantly diminished and they cannot produce enough organic matter to meet their needs. The growth of plants will be slowed by this. The case with orange light is different. The portion of orange light that is close to the red light is beneficial to plants. Because some chlorophyll B has an affinity for orange light, orange light aids in the process of photosynthesis.

Green (500nm-575nm)

The impact of the “green light” on plants has long been misunderstood. In other words, plants reflect green light instead of using it for photosynthesis. It is only partially accurate, though. Green light can now also stimulate plant growth, according to recent research. The green light has excellent penetration abilities. To enhance photosynthesis in chloroplasts on the leaf’s bottom surface and beyond, green light can pass deeper through leaves. Deep within the mesophyll, intense green light stimulates chloroplasts to promote photosynthesis. Green light will assist drive photosynthesis across the entire plant as it is absorbed by leaves in the lower canopy that are not exposed to red or blue light since green light penetrates the lower canopy much more effectively. It will be preferable to have a spectrum of LED grow lights with a tiny quantity of green light than one without it. It is beneficial for enhancing plant photosynthesis.

Blue-violet (400nm-500nm)

Green leaf growth may be aided by blue light. The combination of red and blue light aids in promoting plant blossoming. Plant growth can be accelerated by blue light. Violet affects the hue, flavor, and scent of plants.

Ultraviolet Light (<400nm)

This range of ultraviolet is primarily what reaches the planet. We refer to long ultraviolet typically. The long ultraviolet has a stimulating effect on plant growth, may improve agricultural yield, and encourages the production of proteins, sugars, and organic acids. The germination rate of the seed may be improved if it is exposed to radiation. When a plant’s innate defense systems are triggered by UV-A radiation, the plant produces a kind of “sun screen” to shield itself from the harmful light. When exposed to UV-A, certain plants can manufacture as many as 15 distinct defensive proteins. The synthesis of defense proteins rises along with the exposure to more UV-A. These proteins can improve a plant’s flavor, color, scent, and disease resistance. The ability of seedlings who have ever been exposed to ultraviolet light to adapt to high intensity light is better. when seedlings are moved from a state of low light intensity to one of high light intensity. They experience an adjustment period as a result of the surroundings altering. if ultraviolet A radiation has been applied to the seedlings. This will drastically reduce the time needed to acclimate to the new environment. The healing and quick growth of plants makes perfect sense.

The ozone layer above the earth absorbs the majority of this UV light (280nm-315nm). The short UV has a growth-inhibiting impact on plants and can stop them from growing pointlessly. Adding a modest amount of UV-B can help you achieve your objectives if this UV-B characteristic is what you’re after and you want to utilize it to manage the height of your indoor crops or to conduct more study. It is important to note that this ultraviolet light has the ability to disinfect, sterilize, and lessen plant illness. It is quite harmful to plants in comparison. The future is extremely uncertain. If one day humans find a technique to maximize its sterilizing and disinfection properties while also eliminating its damaging effects on plants. It will open up possibilities for the development of vegetables without pollution.

The ozone layer above the earth absorbs almost the entirety of this range of UV radiation. Plants get severe disruption from it.

the essay. There are several effects of various light wavelengths on plants. We do not, however, refer to the impact of various types of light on particular plants. because it is feasible to achieve very varied effects for many plants using the same light. These discovered impacts serve as the theoretical underpinnings for our study of the best plant spectrums. The ideal spectrums for the cannabis planting have been determined by our Atop lighting, a producer and provider of LED grow lights, by continuously exploring and using practice.

After being introduced, the Horti-King LED grow light is now becoming more and more popular among marijuana farmers. With ideal spectrums, growers’ ability to maximize their benefits can be realized more quickly.
