What Does Indirect Light Mean and Why It Matters?
What Does Indirect Light Mean?
Indirect light refers to light that is not directly shining on a plant but is instead reflected or diffused.
It can be found in areas of a room that receive only partial sunlight, such as behind other plants or furniture.
Different plants require varying levels of light, and light intensity is measured in foot-candles (ftc).
There are three levels of indirect light: bright indirect light (500-1,000 foot candles), medium light (100-500 foot candles), and low light (less than 100 foot candles).
The direction a window faces determines the type of light it receives.
North-facing windows typically receive very little light, while south-facing windows get direct sunlight during the late morning and early afternoon.
East-facing windows receive bright morning sunlight, while west-facing windows receive direct sunlight in the late afternoon.
It is important to understand the different types of sunlight and their effects on plant growth in order to provide the appropriate light conditions for indoor plants to thrive.

1. Indirect light refers to the diffuse illumination that is bounced off reflective surfaces before reaching the desired area.
2. Indirect light is commonly used in photography to create soft and shadow-free lighting, perfect for capturing portraits or still-life images.
3. Many plant species thrive in indirect light as it replicates the dappled lighting conditions found in their natural habitats, such as under tree canopies.
4. Indirect light can create an illusion of spaciousness in interior design by minimizing harsh shadows and distributing light evenly across a room.
5. In architecture, indirect light can be achieved through clever designs such as incorporating skylights, light shelves, or reflective surfaces to redirect sunlight into a space without direct exposure.
Importance Of Light For Houseplant Growth
Houseplants require light for photosynthesis, the process of converting sunlight into energy. This energy fuels growth, oxygen production, and food creation. Insufficient light can make houseplants weak, spindly, and prone to diseases.
Different plants have varied light requirements based on their natural habitats and adaptations. Some thrive in direct sunlight, while others prefer filtered or partial shade. Understanding your houseplants’ light needs is crucial for their health and productivity.

Different Levels Of Light For Indoor Plants
To measure the intensity of light, the unit of measurement used is foot-candles (ftc).
- Direct light refers to the unobstructed, full sun that reaches the plants.
- Indirect light is filtered or partially shaded, protecting the plants from intense sunlight.
There are three levels of indirect light that plants can thrive in:
- Bright indirect light: 500-1,000 foot candles
- Medium light: 100-500 foot candles
- Low light: less than 100 foot candles
The level of light required varies depending on the species of the plant and its natural habitat.
Understanding Indirect Light And Its Effects
Indirect light refers to light that is not directly shining on a plant but is rather reflected or diffused. This type of light can be found in areas of a room that receive only partial sunlight, such as behind other plants or furniture. It is gentler and less intense than direct sunlight, making it suitable for plants that prefer shade or filtered light.
Indirect light can be achieved by using sheer curtains, placing plants away from windows, or utilizing materials that filter sunlight. This type of lighting provides a softer, more diffused glow that promotes healthy growth without the risk of sunburn or scorching the leaves.
Matching Light Levels To Plant Needs
To ensure optimal growth, it is essential to match the light levels to the specific needs of your houseplants. Different windows and orientations offer varying degrees of light.
- South-facing windows receive the brightest light, making them the ideal location for plants that require high-light conditions.
- On the other hand, north-facing windows receive very little light, making them suitable for plants that can thrive in low-light conditions.
- East-facing windows provide bright morning sunlight, which is perfect for plants that require medium or low light.
- West-facing windows, on the contrary, receive direct sunlight in the late afternoon, making them suitable for plants that need medium to bright indirect light.
A light meter app can help determine the level of light a specific room receives. By measuring foot-candles, you can ensure that your houseplants are placed in areas with the right amount of light for their growth and development.
- Use a light meter app to measure the level of light in a room
- Choose the right windows and orientations based on your houseplants’ specific light requirements
- Adjust the placement of your plants to ensure they receive the optimal amount of light for their growth
- Consider rotating plants in order to provide equal light exposure to all sides
Remember, ensuring the right amount of light for your houseplants is crucial for their overall health and well-being.
Tips For Moving Plants Outdoors
In warmer months, moving indoor plants outdoors can provide them with natural sunlight and rainfall, boosting their growth and vigor. However, it is essential to take precautions and gradually acclimate plants to the outdoors to avoid shock or damage.
Start by placing your plants in a shady spot under a tree for a few hours each day. Gradually increase their exposure to sunlight over a period of several days or weeks. This acclimatization process allows plants to adjust to the outdoor conditions slowly.
It is crucial to monitor the temperature, ensuring it does not drop below 55℉ (12.8℃) when moving plants outdoors. Also, be cautious of heavy rain and high winds, as these can damage or stress plants. In such cases, it is recommended to bring plants indoors to protect them.
Inspect outdoor plants for pests before bringing them back inside your home or garden to prevent infestations. Hardy plants that are less picky about light and water requirements, such as the Rubber Tree, ZZ Plant, Snake Plant, and Pothos, are good options to move outside.
If you are unsure about the light requirements of your plants or need guidance on caring for them outdoors, consult experts at your local garden center. They can provide valuable advice based on your specific plant species and environmental conditions.

Frequently Asked Questions
What is considered indirect light?
Indirect light refers to the type of sunlight that has been softened or filtered before reaching a plant. It occurs when an object, such as sheer curtains, furniture, a tree, or even another indoor plant, diffuses or obstructs the direct sunlight. This indirect sunlight is gentle and less intense, providing a more subdued and diffused illumination that is ideal for certain plants that prefer lower-light conditions. The filtering effect creates a softer and more dappled light, which can help prevent direct sunburn or leaf damage for light-sensitive plants, ensuring they receive the appropriate amount of light for healthy growth.
What is an example of indirect lighting?
One example of indirect lighting is wall sconces that are mounted on the walls and emit light upwards. As the light hits the ceiling, it bounces off and spreads a soft, ambient illumination across the space. Another example is pendant lights that are suspended from the ceiling, directing the light upwards to create a gentle, indirect glow in the room. These types of lighting fixtures provide a cozy and welcoming atmosphere by diffusing the light and minimizing harsh shadows.
Where do you put plants for indirect sunlight?
Plants that thrive in indirect sunlight should be placed in areas of the house where there is limited natural light. If you have a room without windows or one where the curtains are mostly closed, it can be an ideal spot. However, if these low light plants do receive some sunlight, it is best to position them near a north-facing window. This ensures they receive gentle, ambient light that is not too direct or intense, which can be harmful to their growth. By strategically placing these plants in areas with minimal natural light or near north-facing windows, you can create the perfect environment for them to flourish.
Is indirect sunlight through a window?
Indirect sunlight can indeed be obtained through a window, particularly when it faces east or west. East-facing windows are known for providing bright, indirect sunlight throughout the majority of the year, making them an ideal choice for individuals seeking indirect sunlight for their plants. Similarly, west-facing windows also offer indirect sunlight during the early morning and afternoon, providing an alternative option for those looking to maximize their exposure to this type of light. In both cases, individuals can enjoy the benefits of indirect sunlight without having to venture outside.
