Succulent plants are not the same when it comes to their light needs. Some, such as snake plants, can go beyond this and cope with as little light as possible while still maintaining their health. But for the majority of succulents, especially if you’re growing them indoors, need a good 4 to 6 hours of direct sunlight a day. This is sometimes difficult to ensure, be it because of the climate, house orientation, or lack of proper space in the windows.
Fortunately, this is no longer a problem since succulents can be grown with artificial light. Moreover, the artificial grow light will give a boost to your succulent plants by preventing their etiolation. It will even help them grow and bloom much faster.
Check out this list of the best grow lights we’ve selected for you so that you can choose one that best suits your succulents.
What are Grow Lights?
What sets regular lights apart from Grow lights is the spectrum of light they emit when they are switched on. They are equipped with full-spectrum horticultural bulbs, which means that they emit more colors in the full spectrum of light – the rainbow. And this is why the common light bulbs used in our homes burn: they use the yellow-orange part of the spectrum which is the “hottest”.
On the other hand, the light emitted by grow lights has a wider range and is evenly distributed, which makes them cooler and less expensive to use, and of course more efficient for our succulents.
Is a Grow Light Good For Succulents?
A succulent that doesn’t get enough sunlight starts to stretch. This is easy to detect because succulents usually tend to grow slowly, and when you notice the opposite, then your succulent is most likely subject to what is called etiolation. A plant is etiolated (ee-tee-oh-late-ed) when it is growing too tall, thin, and stretched as a consequence of getting insufficient sunlight.
Botanists say that this overstretching is a stressed attempt by plants to find light.
All Plants need light for photosynthesis, but not necessarily sunlight. The only condition is to choose the correct type of grow light and photosynthesis can then take place even at night with lights that contain blue and red wavelengths.
Succulents need abundant light for photosynthesis. This is a process used by plants to convert water, sunlight, and carbon dioxide into nutritive energy that allows them to grow, bloom, and reproduce.
Without enough light, as mentioned above, your succulents will be etiolated. They may even die, in severe cases, due to a lack of light. Place them in sunny windows and watch them carefully to detect any signs of stretching.
But keep in mind that most succulents you grow outdoors can’t stand the cold. They will be damaged by a severe frost. So you should bring them indoors in winter when the temperature drops to 40° (about 5°C). Then adopt a suitable watering program, as they will need very little water. The biggest challenge you’ll face now is lighting.
So to give your succulent enough light to grow indoors during winter, it is important to consider using a grow light.
How To Use a Grow Light for succulent?
Once you’ve chosen your favorite grow lamp, remember to have a timer handy. This will ensure that your plants have a sufficient rest period per day, i.e. a minimum of six hours.
Now it’s time to set them up. Decide where in your house you will place the plants and install the lighting. Typically, the installation of each type of grow light depends on its brand; any grow light you buy should be supplied with specific instructions, detailed by the manufacturer, and generally not time-consuming.
We prefer Gooseneck or movable lamps because they make this process simple. They are so versatile and stay in any direction you bend them. If for example the lamp is a little lower and you need to make it higher because of your growing succulent, no need to unscrew it and install a wall mount, just move the lamp’s neck to adapt it to the growing plants.
Later on in our article, we will talk about other installation aspects to be considered: how far should we place grow lights from succulents, how long should they be under them.etc
The 5 Best Grow Lights for Succulents
1. Ankace Grow Light with Red Blue Spectrum
Red and blue spectrum growth lights indeed emit a violet glow that can be a little distracting, but they are widely used by succulents lovers because, quite simply, they perform better.
This combination of red and blue light is essential for indoor succulents to grow and flower. It mimics the multiple layers of sunlight’s colors so plants can grow as naturally as possible.
We appreciate two features of Ankace Grow Light, these same features, among others, make it Amazon’s Choice :
- It has an adjustable gooseneck that allows positioning the light closer or further away from your succulents, which guarantees that they are at the ideal distance from the light (which is usually 18 to 24 inches).
- It has a programmable timer that turns the light off after 3, 6, or 12 hours. You can also reduce the light of this grow light. For example, if your succulents don’t respond well to strong light and get a little sunburn, you can easily reduce it.
2. Extra Wide LED Indoor Herb Garden
This modern LED grow light kit disposes of a white shelf to hold your succulents. It fits harmoniously in contemporary decor and therefore looks more like a decorative element than a grow light.
Unlike the previous kit, it doesn’t emit violet light that might be disturbing for some of you, but it is equipped with white LEDs (Light Emitting Diodes).
It is also equipped with an AUTOMATIC SMART TIMER, which turns the light on for 16 hours and turns them off for 8 hours, which makes the lighting process easier by automatically giving your succulents the perfect amount of artificial light they need each day.
This grow light is large enough to hold a few medium-sized succulent pots. It measures 16.5in (L) x 10in (W) x 11.4in (H)

This full-spectrum grow light bulb from SANSI has a superior color rendering index (CRI) compared to other leading brands on the market, making the light it produces the closest to natural sunlight, which is the optimum light for plants.
On the product’s Amazon page, users are pleased with it. Some of them have confirmed that they have obtained impressive results. One buyer even said that her plants are growing faster and looking more vibrant than they did with natural sunlight alone.
Another nice feature of this LED light unit is that it can be hung on a hook, a wire, or simply placed on its handle on a flat surface.
4. Jump Start 4′ T5 Grow Light System

Frequently Asked Questions
We’re gonna try to answer some frequently asked questions related to succulents grow lights.
We hope that you will find a solution to a problem you have encountered. If not, you can share your concerns in the comment section. We’re always glad to be of help!
How far should LED grow lights be from succulents?
Do not neglect the distance between your succulents and the light, because if it is too far away, your plant will not receive the necessary lighting. If it is too close, the heat from the bulbs might burn them. The exact distance depends on some other factors, but normally it should be at least 6 inches and should not exceed 40 inches.
If you are using LED or fluorescent grow lights without gimmicks, a gap of 10 inches is perfectly sufficient. However, in the case of larger succulents, you can reduce the distance 6 inches.
But be careful, at a distance of 5 inches or less from the light, water can heat up inside the leaf cells, trunks and stems. At a certain stage, your succulent will dehydrate or even burn.
How long should grow lights be on for seedlings?
The more light, the more growth! An experiment was carried out here on putting the seedlings 24 hours under the light vs. 16 hours. After a few months, those exposed to 24-hour light were a few weeks ahead of their 16-hour counterparts.
The great benefit of using grow lights for seedlings is that they will be much more resistant and compact because of a sufficient amount of light. So you should start putting them under lights as soon as the first seeds start to sprout.
They need 14 hours of light per day and should be placed four inches under the LED lights. As they begin to sprout, rotate them every week to allow them to grow evenly. Of course, after the seedlings have matured, you will have to reduce their exposure to light.
Can you leave grow lights on 24 hours a day?
Generally speaking, it is not recommended that grow lights be left on 24 hours a day.
The National Park Service says that cacti and other succulents open their stomata to absorb carbon dioxide at night as compared to during the day, preventing unnecessary moisture waste. That carbon dioxide is then retained until daylight returns and photosynthesis resumes.
In simplified terms, plants’ activity during daylight consists of absorbing light for photosynthesis, so it makes sense that they would grow at night.
With this in mind, we also know that most succulents expect at least 4 to 6 hours of light a day to make them happy and fit. Of course, you need a timer when you use grow lights, to ensure that they always receive the right amount without your assistance.
- If you don’t have a grow light for your succulent or if you are short of space under the grow light, use a little trick: place it next to a mirror, well oriented, to give it an appreciable extra brightness.
- Do not keep your succulents at just one angle to the light source. Rotate them every week so that each side receives the same amount of light.
- Put your hand over the plant and underneath the light. If it is hot, the plant is too close to the grow light and should be repositioned.
- It is never a good idea to place a succulent that has overwintered in your home or veranda suddenly in the sun. We advise you to gradually get it used to this change to avoid burns. Shade it lightly for a couple of weeks with a shading net (or mosquito net) that will filter 25 to 50% of the sun’s rays. Or don’t point it south right away.
Not Using a Succulent Grow Light?
To be honest, it is not necessary to have lamps grow lights for your succulents, even during the winter season. You can lit through your home’s windows, or switch to succulent plants that require only low light for their maintenance. However, if you can’t provide good lighting, and your succulents need a lot of it to survive then you need to consider bringing them grow lights!
