Plants that receive no external light need typically be lit between 16 and 18 hours per day. If more light is received, 12 to 14 hours per day would be sufficient. The same time that plants receive window light is when lights should be employed. Unless natural sunshine is very bright, using lights at the start or end of the day is typically less effective than using lights during daylight.
Do houseplants require sunlight or just light alone?
- Choose a plant whose lighting needs match those of your house or workplace.
- A lack of natural sunshine can be compensated for by additional lighting.
- To suit your needs and budget, artificial lighting is available in a wide variety of forms and sizes.
One of the most crucial elements for cultivating indoor plants is light. For photosynthesis, the process by which plants turn light, oxygen, and water into carbohydrates, all plants need light (energy).
This energy is necessary for plants to develop, bloom, and set seed. Without enough light, plants cannot produce carbohydrates, their energy stores run out, and they eventually die.
Is there enough light inside for plants?
The answer is complicated because natural light is always preferable to artificial light for plants. The majority of home gardeners will find that indoor lighting is insufficient to keep their plants as healthy as they would be outdoors. However, it is doable with the right tools.
The cost of indoor plant cultivation is the biggest drawback. It can be very expensive to get the correct lighting and bulbs that mimic the sun.
Similarly, a lot of electricity will be required to duplicate the sun. Additionally, your electricity bill will be exorbitant.
Plants that require a little more light are the greatest candidates for indoor illumination. For instance, regions of the world’s extreme north or south may experience lengthy winters with little sunlight. An additional source of light may be required at this time for a temperate indoor plant.

What does it actually mean when a houseplant needs direct sunlight while another needs indirect? We wanted to know if the plants we were growing in “direct light” were indeed receiving the necessary amount of sunlight. Here is what we discovered.
Is light coming in through a window regarded as direct sunlight? It varies. Direct sunlight is when the sun is shining directly on the plants, such as via a south-facing window. Indirect light is what is produced when the sun is shining brightly but doesn’t reach the plant directly.
When working with indoor plants, the distinctions between direct and indirect sunlight might be a little unclear. Let’s examine light’s behavior more closely as it passes through windows.
What does low light mean in terms of indoor plants?
It’s time to welcome a new plant into your house, which also means that you need figure out how much light your room gets! The most important factor to take into account when choosing a new plant mate is how much light they demand. And although it could seem a little perplexing at first, don’t worry! This website was created just to help you make a successful plant selection for your environment. We’ll determine the amount of light that comes into your space, explain what concepts like strong indirect light truly imply, and, of course, make sure that your option is the ideal one with recommendations for each room in your house.
What is Indirect Sunlight?
What distinguishes indirect from direct light, and what does “low light” mean according to green thumbs? While some of these phrases can’t be defined precisely, having a rough understanding of each one will help you choose the proper plant.
Direct light is the light that enters via windows with a southern or western orientation. Direct light exposes plants to the sun’s rays directly and is the most intense form of lighting that indoor environments receive. The majority of common houseplants don’t like direct sunshine, but some do, including cactus, succulents, fishtail palms, and birds of paradise.
Bright Indirect Light is constant and bright despite not being direct. Consider the areas that are immediately adjacent to windows that receive a brief amount of direct light each day (up to an hour) before it is blocked. For the plants in this collection, it is perfect.
Areas of a room with medium light are those that are roughly half way between a window and the rear wall. These regions continue to receive constant, indirect light from the windows. Numerous palms, Dracaenas, Philodendrons, and other plants in our medium light selection thrive under this light.
Low Light – Low light locations include those that are at least seven feet from windows as well as those that have no natural light, such as certain offices and restrooms. Many plants can adapt to low light, and some thrive in it. Although low light plants grow more slowly than other plants, there are still a wide variety of choices. Our low light collection is a treasure trove of indoor plants that prefer shade.
Can I Use Artificial Light for my Plants?
Yes, to answer briefly. Light from lightbulbs, and grow lights in particular, emits artificial light. Although they nonetheless make a contribution, standard lights and overhead lighting do not provide enough light for plants to photosynthesize. , so you should choose a low light plant if the only light sources available are standard lamps and overhead lights. But grow lights, which you can learn more about here, provide light that plants can easily photosynthesize.
Understanding Your Light and Space
Which type of lighting do you use? A fast hand test is a quick way to find out. Hold your hand about a foot away from a piece of paper or another flat surface so that it is between the light source and the paper. You are receiving low light if there is little or no shadow visible. You will see the shadow of your hand in medium light as hazy or fuzzy, and in strong light as a sharp, distinct shadow.
It will be easier to decide what kinds of light you’re working with if you know which way your windows face:
North Facing Windows
True north-facing windows are never exposed to direct sunlight (at least in the Northern Hemisphere). They constantly receive mild, diffuse light. When placed four or more feet from north-facing windows, plants from the Medium Light Collection including the Dracaena Lisa, Braided Money Tree, and Snake Plant will thrive.
South Facing Windows
Any room with south-facing windows is the highlight because they receive the most natural light throughout the day. The sun rises in the east, and as the earth spins, it shines through windows facing south from late morning until midday. Most plants will enjoy being close to this window because south facing windows offer bright light for the majority of the day, especially light-loving plants like the Bird of Paradise, Fishtail Palm, and Desert Cactus.
A word about direct sunlight: Most plants don’t like to be in the harsh direct rays of the sun, and unblocked south-facing windows will receive a considerable bit of it. When positioning specific plants in front of a window that receives a lot of direct sunlight, use caution.
East Facing Windows
East-facing windows are illuminated in the morning (the sun rises in the east). East facing windows are a nice match for plants that prefer indirect bright light because morning light is often mellow. An east-facing window is one from which you can view the sun rising. It’s a good idea to place plants that appreciate bright indirect sunlight close to east-facing windows, such as the Fiddle Leaf Fig and Monstera Deliciosa.
A word about direct sunshine: Most plants can tolerate direct sunlight from east-facing windows, and morning sunlight is typically a mellow light. Keep an eye on things in the summer, when the sun may become too harsh for plants that would usually enjoy basking in it throughout the rest of the year, if you live somewhere that receives a lot of sunshine (lucky you!).
West Facing Windows
The sun is high in the sky by midday and getting ready to start its gradual ascent as it sets in the west. West-facing windows will receive some sunlight from mid-afternoon till dusk. Your window is west-facing if you can see the sun set through it in the late afternoon. Most plants should be positioned outside the regions where direct sunlight hits because the light obtained by windows facing west is particularly strong when it is direct. A Braided Money Tree or Tiger Evergreen will benefit from the indirect light coming from this direction, and desert cacti and succulents are among the few plants that can withstand the direct sunlight coming from a west-facing window.
You can also use a compass (which seems hard but is incredibly convenient and is a very useful tool!) or landmarks to establish which way your windows are facing.
Meet Your (Light’s) Match
For every level of light, choose from this selection of our all-time favorite plants. Some plants may appear on many lists, as you may have noticed. There is no error here! Some plants are fortunate enough to grow in various levels of indirect light. These superstars include snake plants and braided money trees.
Can LED lighting aid with plant growth?
The least expensive technology is incandescent grow lights, but they are also the least energy-efficient and produce a lot of heat.
Fluorescent lights produce a good spectrum of light for growing and have a minimal heat signature. They often come in the form of reflectors for tube lights or CFLs. Growing under fluorescent lights is more cost-effective than growing under incandescent lights, although it uses less energy.
The most recent technology on the market is offered by LED grow lights. They are incredibly energy-efficient, produce incredibly little heat, and have the perfect light spectrum. The most effective, efficient, and user-friendly way to grow plants at home is with LED lights rather than fluorescent or incandescent lighting since they use less energy, produce less heat, and have colors that are tuned for growth.
A tungsten electrode and an alumina-fused tube form an electric arc to create light in high-intensity discharge (HID) bulbs. These speciality bulbs are frequently employed by industrial growers and have a very high light output level.
A strong light source is produced by metal salts and mercury vapor in metal halide lights. Like HIDs, they make use of a unique fixture and are frequently employed by commercial establishments.
How long should plants be exposed to artificial light?
It can be challenging to provide plants the right amount of light while they are being grown inside in order to keep them happy and healthy. Winter has arrived, which further reduces the quantity of natural sunlight accessible because the days are shorter and the nights are longer. At this time of year, the sun’s strength is also lessened. Artificial lighting should be used to augment or replace natural sunshine in order to cultivate healthy, beautiful houseplants and to maintain the bloom of blooming plants throughout the winter.
The light that a plant is exposed to must closely resemble sunshine for healthy growth. All of the hues in the spectrum are present in sunlight, and each is essential for the process of photosynthesis. Two of the most essential hues for the growth of plants are red and blue. Red encourages vegetative growth and flowering, but too much of it will make a plant lanky and strained. A fuller, stockier plant results from blue’s control of plant growth. Select a full-spectrum fluorescent gro-bulb for the best effects. For the healthiest and most vibrant houseplants, this lighting option is ideal.
Varying plant species require different levels of light. While some plants like dim lighting, others need intense light. The wattage of the lightbulb and the distance between the light source and the plant dictate the amount of light that is produced by artificial lighting. Knowing which plants to gather together beneath the fixture and where to position a light will tremendously aid you when choosing where to do so. Plants produced primarily for their leaves typically need less light than those grown for fruit and flowers, as a general rule of thumb. Plants exposed to artificial light should be rotated every week because the light from tube-style bulbs is stronger in the middle than at the ends. To enhance the quantity of light available to your plants, use white trays, mirrors, or trays lined with foil.
The majority of houseplants thrive with 12–16 hours a day of artificial fluorescent light. A plant will grow tall and spindly if it receives insufficient light, and it will wilt, lose color, have overly dry soil, and burn its leaf if it receives too much light. Each day, plants too need to take a break. Your plants’ development rate will be slowed down by an 8–12 hour period of darkness each day, which will also provide them the rest they need to form flower buds. For instance, the Christmas cactus requires six weeks of uninterrupted darkness—13 hours each day—to set bloom buds. The Christmas cactus won’t flower if it doesn’t get the necessary amount of downtime. To control the length of time your indoor plants are exposed to light and darkness, use an automatic timer.
The ability of the fixture to be adjusted is crucial when picking a plant light fixture. The fixture should be movable up and down to accommodate the various plant species’ differing needs for light intensity and growth height. You will be limited in the kinds of plants you can grow and how much you can use the fixture if it is not adjustable. Both adjustable shop lights and tabletop light fixtures are suitable for illuminating indoor plants. The size of the fixture is another factor. The amount of plants you intend to grow below the light should guide your size selection. Plants can be grown on multiple levels of lighting shelves that are provided by illuminated plant carts. While tabletop fixtures are lightweight and may be moved to new locations when needed, carts have wheels that make them portable.
Starting to use artificial light sources may seem scary, but you’ll be astonished at the impact it will make to all of your indoor plants, both houseplants and seedlings.
Instead of sunlight, can artificial light be used to produce plants?
Plants can thrive in artificial light, but it doesn’t have as much red and blue light as natural sunshine and isn’t as bright. Utilizing LED lighting in specialized indoor growth chambers can help plants grow more effectively by reducing the contrast between artificial and natural light.
Photosynthesis is a superpower of plants that enables them to produce all of their own sustenance. All they require is some water and carbon dioxide. The plant requires some energy, which it obtains from the sun, to power this cooking process.
Sadly, not all areas of the world experience year-round brilliant sunlight. The sun is only visible for less than 8 hours a day in the Earth’s poles, in places like Antarctica and Iceland in the south and Iceland and Finland in the north.
In addition to seasonal changes, cities with their concrete jungles present challenges for indoor plants. Many homes can be darkened by skyscrapers and high-rise structures. What therefore should those of us who garden but also live in cities do?
