The majority of succulents favour direct, strong light. Even in less than perfect indoor lighting conditions, certain succulents can still grow. The succulent species that can thrive in low illumination conditions are listed below.
The huge genus of miniature succulents known as Haworthias is indigenous to South Africa. Some haworthia species have a look that is very similar to aloe vera and can be mistaken for it. Depending on the species, these plants produce rosettes of various sizes and shapes.
Some are solitary, while others form clusters. Most have substantial roots. Some species have softer, plumper leaves with translucent, glassy surfaces that let sunlight to pass through for photosynthesis, while others have thick, stiff, fleshy leaves that are often dark green in colour.
Although most haworthia species can grow in low light, bright, warm settings are prefered for their appearance. Be extremely careful not to overwater the plant when it is cultivated in low light. Under low light circumstances, overwatering the plant might be harmful.
Rainforests in South America, the Caribbean, and Central America are home to the cacti genus Rhipsalis. Rhipsalis species do not flourish in direct sunlight and extremely dry soil, contrary to popular belief that cactus require strong sunlight and dry circumstances. Usually, these plants are grown indoors.
They thrive in the morning light and afternoon full shade. The surrounding, heavily overhanging tree branches provide the rhipsalis with plenty of shade in its natural habitat. In comparison to most cactus, they are also more adaptable to increased humidity. Rhipsalis requires routine watering because it is not drought-resistant.
Overwatering should be avoided, though, as it can lead to root rot. The Rhipsalis Baccifera, sometimes known as the mistletoe cactus, is one of the most well-known rhipsalis species. These plants thrive indoors and need shade or partial shade.
The bloom that this genus produces, which has the appearance of a stomach, gave rise to its name.
The Latin word for stomach is gastro. They are indigenous to South Africa and require a lot of rain and light shade to grow.
These are now able to tolerate low light levels and have developed good indoor growing habits. Additionally, they thrive in warm, direct light. They have curving, stomach-shaped blooms and long, thick, grooved leaves. They prefer sandy soils with good drainage.
Schlumbergera is a member of a tiny cacti genus. They are native to the Brazilian tropical rainforests and require some humidity. They cannot stand extreme heat or cold. The look and behaviour of Schlumbergera species are distinctive from those of other cacti.
They grow on trees in moist, humid environments as epiphytes or as lithophytes on rocky terrain. Schlumbergera stems develop joints that might be flat, shaped like leaves, or shaped like bottles. All seasons see green growth on the stems.
The Christmas Cactus or Thanksgiving Cactus is one of the most popular types and has gained popularity as a houseplant due to its stunning, spectacular blossoms. This tropical cactus does not thrive in afternoon or full sun.
Which type of grow light is 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 glasshouse installations). These two choices are among the most accessible grow lights and are excellent for succulents.
LEDs
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.
Are succulents more attracted to blue or red 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 LED light hue works best for succulents?
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 instal the lighting and the plants.  
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 colour 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.  
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.
With our selection of the best indoor succulents, enjoy your gardening. They are fantastic for any house, workplace, or garden to create the ultimate green area because they are simple to cultivate, very versatile, largely pest-free, and low care.
Succulents can they grow in LED lighting?
I don’t have much experience growing succulents in cold temperatures and dark winters because I live in sunny Southern California. I’m fortunate enough to be able to leave my plants outside all year long without significant frost or low light harm. I am aware that many of you reside all over the world and are unsure of what to do with your plants now that you have brought them indoors for the winter. Perhaps despite the fact that you have your plants on window sills, they are still growing languidly, or perhaps the winters in your area are completely dark. Look nowhere else! I’m very happy to have indoor plant growing specialist Ben Thorton here with us today to share his knowledge about using grow lights to support the growth of your lovely garden regardless of the lighting situation!
Succulents have recently risen to the top of the list of prefered indoor plants because of how attractive they are, how they enhance the atmosphere of your home, and how little maintenance and water they need compared to other indoor plants. Many people are reluctant to grow succulents in regions with short summers because they are warm-weather and sun-loving plants. You might be shocked to learn that even if you live in a climate with distinct seasons and chilly, gloomy winter months, you can still grow succulents all year round. Once the weather becomes cooler, just move the succulents inside and provide the artificial lighting they require. Here is a simple tutorial on growing succulents indoors and under artificial lights if you are unsure about using grow lights or worried that you might harm your plants by using them.
Artificial lighting can be categorised as either lighting used in addition to natural lighting or lighting utilised to perfectly mimic sunlight in situations where none actually exists. Since vitamin D, one of the most important vitamins in the human body, is obtained from sunlight, artificial light cannot replace it for humans. In contrast to other living things, plants just require the light itself from the sun. Photosynthesis is a process that takes place when plants are exposed to light and provides them with the energy they require to grow. Succulents can be grown indoors under artificial light just as well as outdoors in natural sunshine, provided that the right amount of light is provided. To successfully grow your succulents in your house, you will need to select the best lights and understand a few basic lighting techniques.
There are a few considerations to keep in mind when selecting artificial lighting for an indoor garden. And they are as follows:
How strong and bright is the light produced by the grow lights?
The brightness of the light produced by grow lights is the most important factor to consider because it will affect how much light the plants receive and how well they can grow. You need lights for succulents that produce at least 2,000 lumens per square foot of illumination. 10,000 lumens per square foot are produced by noontime direct sunlight, but if you run 2,000 or more lumen lamps for 14 or more hours a day, the plants will receive almost the same amount of light as they would in the height of summer.
What is the light’s wattage?
Another item to consider is the wattage of the grow lights you buy, as this will have an impact on your electricity bill. You pay more for electricity the more watts a light uses, therefore you don’t want to choose a light that is brilliant but uses a lot of watts because that will be very expensive. To get the best of both worlds—bright light for your plants and minimal electricity consumption for you—look for lights that are marked as energy efficient. These lights will likely have a high lumen count and low wattage, giving you the best of both worlds.
What colour temperature range does the light produced by grow lights fall into?
Because succulents love the sun and prefer bright light to shadow, they also need a particular light with regard to the colour temperature of the light. The visible colour that the grow lights emit is essentially their colour temperature. Kelvins are used to measure this. To provide the light that plants require to thrive, light must fall within a certain range of colour temperatures. Starting at roughly 5,000 Kelvins, the ideal colour temperature for succulents will provide your succulents cool, full-spectrum light that closely resembles sunlight.
How much heat is emitted by the light?
Finally, it is crucial to understand how much heat the grow lights emit. If they produce a lot of heat, you can experience a problem with the temperature in the space where you grow your succulents, which would require you to invest extra money in a reliable ventilation or cooling system. Additionally, if lights produce a lot of heat, you will need to situate your plants farther away from the lights in order to prevent them from burning them. Your plants may not receive enough light as a result. Some typical grow lights are known to emit a lot of heat, while others remain cool to the touch even after being on for 24 hours. Make sure a grow light doesn’t produce too much heat before you buy one.
I would advise you to purchase T5 grow lights since they have all the qualities of a good grow light and I have experience working with many various types of grow lights. Their diameter is 5 eights of an inch. T5 grow lights are available in a variety of configurations, including two different lengths (2 ft and 4 ft bulbs), numerous different bulb counts (from 1 to 12 bulbs in one fixture), various efficiency types (Normal Output (NO), High Output (HO), and Very High Output (VHO), and various colour temperature varieties (from only 2,900 Kelvins up to 10,000 Kelvins). I typically use high output (HO) bulbs because a 2 foot HO T5 bulb uses just 24 watts and produces 2,000 lumens, compared to a 4 foot long high output (HO) T5 bulb that uses 54 watts and produces 5,000 lumens. You obtain incredibly effective light that is ideal for succulents if you mix one or the other length bulbs in a group of two or more bulbs and choose bulbs that are in the colour temperature of 6,500 Kelvins.
Although choosing the correct artificial light is an important aspect of effectively growing your plants in an indoor garden, there are a few other factors you should be aware of in order to do even better.
Be aware of the height at which you should hang your plant canopy’ grow lights.
Knowing how high to hang your grow lights is essential since it affects how much light the plants receive. You must hang grow lights so that they may provide the maximum amount of light to the plants without overheating them by radiating heat, regardless of whether you select T5 fixtures or select other grow lights. In order to reduce the risk of your grow lights burning and harming your plants, I would first advise placing any grow light at least 6 to 8 inches away from the tops of your succulents. You can later move your lighting fixtures closer to the succulents if you discover that they don’t emit heat and are cold to the touch (like T5 grow lights).
Determine the light cycle
Because there won’t be a sun to determine when plants receive light, you must determine the plants’ light cycle while growing plants indoors under grow lights. Knowing your light cycles will help you grow your succulents more quickly. Indoor gardens use light cycles to replicate day and night circumstances. Succulents will also develop more quickly if you give them more light, which is a common rule of thumb for growing any plants under lights. If you’re overwintering the plants, I’d recommend starting with a 20/4 light cycle for the succulents. This means leaving the lights on for 20 hours a day, turning them off for 4 hours, and then gradually extending the darkness time until the light cycle is 16/8 (light/dark). Succulents require knowledge of the winter solstice so they can begin their dormant period. If you use grow lights all year for your succulents, you may set the light cycle to 24/0 or 20/4 in the summer to help them develop swiftly and flourish.
Learn how frequently to water your succulents.
Finally, it should be noted that watering is equally crucial because both inadequate and excessive watering might harm your plants. Even if you’re using grow lights to simulate summer, you still need to water the succulents during the summer by watering them once the soil is dry. Even if succulents are cultivated indoors, things change over the winter. Succulents use substantially less water while they are dormant throughout the winter or an imitation of winter since they are either growing very slowly or not at all. So, how frequently should you water succulents in the winter? In general, I’d advise watering them every two weeks, but if the room is hot, you’ll need to water them more frequently because the heat will cause them to dry out more quickly. Looking at the soil in which succulents are growing will tell you how frequently they need watering during the winter. Allow the soil to dry up completely before giving succulents approximately a week to absorb the water before you water them again to prevent overwatering.
