Depending on the type, succulents need six hours of sunlight each day because they are light-loving plants. You might need to gradually expose newly planted succulents to full sun exposure or give shade with a translucent screen because they can burn in direct sunshine.
How much light are required for indoor succulents?
Like other plants, succulents go between growing and dormant seasons. Although most succulents become dormant in the winter and consequently require less light, they still normally need as much light as they can obtain indoors.
When grown indoors, succulents won’t experience genuine dormancy until you force it with variations in temperature and light.
For a healthy growing cycle, all succulents require darkness every day, but they also require at least six hours of sunlight each day to be flourishing. I leave grow lights on for roughly 12 to 14 hours to simulate natural sunshine plus a few hours when caring for my indoor succulent plants.
Based on the season, you may use this post to determine which of your plants will require more or less water.
Succulents can they survive in low light?
The most light is reflected from south-facing windows throughout the day in the northern hemisphere. The sun shines through windows facing east in the morning and west in the afternoon and evening. The least quantity of sunlight enters windows that face north.
A south-facing window is the best choice for the majority of sun-loving succulent plants in the northern hemisphere. However, all of the low-light succulents covered in this article happily flourish in windows that face west or east. Even in a dark, north-facing window, some of them will make it, but I don’t advise it because even there, they won’t thrive.
However, no succulent can live in a completely dark environment. Therefore, even if your succulent plants are varieties that thrive in low light, think about buying a tiny desktop grow light if you live in a basement flat, have only a north-facing window, or if your space has no windows at all. When a modest grow lamp is placed over low light succulents for 6 to 8 hours a day, you’ll be astounded at how well they grow. You won’t need to remember to turn the lights on and off every day if you have a reliable timer.
Now that you are aware of how much sunlight low light succulents require, allow me to introduce you to some of the greatest low light succulents.
How can I determine whether my succulent needs more light?
Succulents quickly begin to display signs of stress from excessive heat or intense sunlight.
Succulents frequently “blush” or change color when they are receiving enough sunlight. What a lovely transformation to witness!
However, if they begin to receive excessive sunlight, the leaves will actually burn. The succulent leaves may start to show white or pale areas. This harm cannot be undone.
As an alternative, make an effort to relocate your plant to a location with less intense sunlight and wait for new leaves to emerge. It is optional to remove damaged leaves if there are just one or two of them.
The leaves may truly turn dry and black in rare circumstances. The margins of the leaves will first turn black, and it will be dry and crispy (in contrast to blackening from rot which starts in the middle of the plant and is wet and mushy).
Once more, this injury won’t go away until the leaf totally withers and new leaves emerge.
A succulent in the shade may start to turn a golden or yellow tint if it is still quite hot outside. Instead of turning entirely white, as would happen with sunburn, the succulent instead appears warmer or more yellow than usual.
If the succulent is transferred to a colder setting, this usually disappears or the succulent returns to its normal hue.
I can keep succulents alive very well sometimes, but not always.
I recently relocated to Arizona from Utah. Growing succulents can be challenging for a variety of reasons, including relocation. You must pay close attention to how much heat and sunlight each area of your garden receives.
Although it’s a little humiliating, I’m going to show you what my garden looked like when it received excessive sunlight and heat in the video below.
Hopefully, this example will show you what to watch out for so that your garden doesn’t turn out like mine did.
Is direct or indirect sunlight preferable for succulents?
I’m regularly asked on Instagram for advice on how to grow succulents, so I thought it would be a good idea to provide those instructions here as well. I consider myself a succulent aficionado, but I am by no means an expert, so let me start there. (Always feel free to correct me!) Given that my plants are all quite robust and numerous, I’d love to share with you what has worked for me.
When cultivating succulents, I’ve discovered that there are three key things to take into account:
Soil
Succulents prefer soil that drains properly. For a while now, I’ve been purchasing a Palm & Cactus mix from Lowes, and it’s been fantastic. I’ve discovered that my soil dries out a little bit too rapidly during the hotter summer months. If your soil doesn’t seem to be holding onto water for long enough, you can add a little bit of ordinary potting soil to your cactus soil to improve water retention. Tea cups, Mason jars, and baby food jars are a few examples of containers I occasionally like to use for my plants because they don’t have drainage holes. To aid with drainage concerns in this situation, I will either add sand to the soil or stack stones on the bottom of the container.
Water
The idea that succulents don’t require much water is a prevalent one. They may be able to go longer lengths of time without it, but they won’t “thrive” in a scenario similar to a drought. This is a lesson I had to learn the hard way when I initially began my collection. My plants would become dry for weeks at a time, and they would not grow. They weren’t also perishng. On the other hand, my mother regularly watered her plants, and they were thriving! I started giving my plants more frequent waterings after deciding she was right. Now, I always recommend watering the soil when it is dry. For me, that is roughly once per week in the summer and a little less in the winter. I water the earth, not the plant, when I water. (I’ve heard that allowing water to collect on the leaves can lead to rot and leave ugly stains.) I soak it thoroughly until the water drains from the bottom of the saucepan. (I don’t soak plants that don’t have drainage holes. I tend to “sip” more.) I frequently witness people overwatering their succulents to death. By making sure the soil is completely dry in between waterings, you may prevent this.
Sunlight
Succulents thrive most in direct but bright sunshine. Different species can tolerate various levels of light, but I’ve noticed that the majority of my plants tend to suffer in prolonged exposure to direct sunshine. Keep your plants where they get a lot of shade but still get enough light to prevent burning and scorching. My healthiest plants can be found outside on window sills, where modest overhangs shield them from direct sunshine. As I previously mentioned, certain plants are more tolerant to direct sunlight than others. To find out what grows best where you live, you simply need to experiment with your plants. Your plants may grow lanky and extend toward the light if they don’t receive enough light. Your plants can be kept growing straight up by rotating the pot occasionally or slowly moving them to a brighter location if they are bending or extending out toward the light. You might want to multiply your lanky succulents. (For further information, see my post on propagating succulents.)
Is it possible to use any LED light as a grow light?
You want to give your indoor plants a boost, but it doesn’t make sense to spend a lot of money on plant lights when standard LEDs would do. However, can plants be grown using standard LED lights?
While standard LED lights may emit some of the wavelengths required by plants, they cannot be utilized as grow lights. Regular LED lights don’t produce as much light as what plants need. LED grow lights are made to enhance red and blue light, which is what plants mostly need for growth.
The reasons standard LED lights are not the ideal for growing plants are covered in the next article, along with how much growth you may anticipate from your plants if you solely use regular LEDs. We’ll also offer advice on what to look for in an LED light that you plan to use for plant growth.
Succulents can they grow in artificial light?
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 preferred 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 categorized as either lighting used in addition to natural lighting or lighting utilized 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 color 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 color temperature of the light. The visible color that the grow lights emit is essentially their color temperature. Kelvins are used to measure this. To provide the light that plants require to thrive, light must fall within a certain range of color temperatures. Starting at roughly 5,000 Kelvins, the ideal color 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 color 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 color 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.
