What is considered indirect sunlight?
Indirect sunlight occurs when something in the path of light from the sun diffuses or filters the sunlight before it hits your plants. Examples include sheer curtains, a piece of furniture, a tree outside your window, or even another indoor plant placed in front to protect the lower-light plant.
Direct sunlight reaches the Earth's surface when there is no cloud cover between the sun and the Earth, while cloud cover causes indirect sunlight to reach the surface. In gardening, sunlight falling directly on the plant is direct sunlight, while indirect sunlight refers to shaded areas.
Virtually all commercial and automobile glass blocks UVB rays. As a result, you will not be able to increase your vitamin D levels by sitting in front of a sunny window, though much of the UVA radiation will penetrate the glass and may be harmful.
Light. Household light varies in intensity, depending on the season and the exposure. South-facing windows provide the most light: direct sunlight within 2 to 3 feet of the window; bright, indirect sunlight up to 5 feet from the window; and semi-shade up to 8 feet away from the window.
FULL SHADE: Shade all day. Under Full Shade conditions, plants do not receive any direct exposure to the sun. Under such growing conditions, plants receive only reflected, indirect light.
Indirect Light: Indirect light can be found in places with an east-facing window, or in an interior of a room that receives full light from a south- or west-facing window. This can also mean there's a sheer curtain between the light source and your plant, for instance.
Here's Why: Can you get vitamin D through a window when sunlight streams in? The answer, in general, is “no.” It might seem like glass lets all the sun's UV rays get through to you, but that's just an illusion: glass – as well as plexiglass and plastic – absorbs all UVB radiation.
Direct light is when the sun's rays hit the plant without any obstruction. Inside, this will usually only occur when the plant is placed on a windowsill or close to a glass door.
Yes, your indoor plants can photosynthesize even if their light sources passes through a glass windowpane. In fact, your plants aren't particularly discerning about what light source they use, provided the light is sufficient for photosynthesis.
Daylighting is a term used to describe the amount of natural light passing through a window, door or skylight. Daylighting is impacted by the size, placement and type of windows in a home or other structure. Daylighting helps reduce the need for artificial lighting in a home, therefore saving energy.
What type of heat is sunlight through a window?
The radiant energy that strikes a window is referred to as solar energy. This energy is made up of ultraviolet, visible light and infrared energy.
Solar Heat gain refers to the amount of heat gain in a building as a result of the glass absorbing the sun's radiation. The amount of solar gain increases with the strength of the sunlight and the ability of the glass to transfer the radiation.
Indirect light examples include; ambient room lighting, filtered light through blinds or curtains, and reflected light from walls and surfaces.
What is Full Sun? Full sun is defined as six or more hours of direct sun per day. If you live in a newly constructed development or out in the country where there are few trees, your garden may not see any shade at all during the day.
Bright indirect light means indirect light (light where the sun isn't shining directly on the plant's leaves) of intensity over 3,000 lux (300 fc). Most house plants need bright indirect light to grow well and be happy and healthy.
“Full sun” definitely means at least six hours per day, but some plants such as vegetables really need eight to ten hours per day. “Partial sun” or “partial shade” means that the plant needs 3-6 hours of direct sun per day.
Plants that need bright, indirect light do well in east-facing windows. West Facing Window (afternoon sun, hot and bright) - Western windows will receive more indirect light in the early morning and early afternoon.
As the sun rises in the east and sets in the west, the south side of any house will see the most hours of sunlight during the day – especially in the Northern Hemisphere – so a south-facing garden takes advantage of this.
Shade. While it might seem counterintuitive, you can still get your daily dose of vitamin D without being in direct sunlight. When you sit in the shade, your skin is exposed to scattered UVB rays.
Resource: Sunlight is the natural light from the sun, while Grow light is a type of artificial light specifically designed to mimic the sun's light. Colors: Sunlight is composed of multiple colors, including blue, green, and red, while grow lights are often just one color (usually red, blue or green).
Can plants get sunlight through window film?
While a transparent window film filters out 99% of UV light, it still transmits 80% of visible light — plenty for your house plants. For plants that typically wilt before the end of a sunny day, you may notice that they actually thrive even better once the window film is installed.
If you happen to have thin curtains or net curtains on your window, they will reduce the amount of light coming through, creating a perfect filtered light level in which many of your plants will live happily ever after. We could say that filtered light and bright indirect light are two equivalent light conditions.
East-facing windows provide bright, indirect sunlight during the day and throughout the majority of the year. For plant lovers needing indirect sunlight, an east-facing window is your best bet. West-facing windows also provide indirect sunlight in the early morning and afternoon.
Heat is transferred to and from objects -- such as you and your home -- through three processes: conduction, radiation, and convection. Conduction is heat traveling through a solid material. On hot days, heat is conducted into your home through the roof, walls, and windows.
If sunlight is streaming in through a window in a room, then we can make it fall on a wall which is on the same side as the window with the help of a mirror. A mirror reflects the sunlight falling on it in the other direction. A mirror is a highly polished surface. reflection occurs from the surface of a mirror.
When you consider that a single pane of glass can lose almost ten times as much heat as the same area of insulated wall, it is worth taking some simple steps to reduce heat loss through your windows to make your home more comfortable and reduce your heating costs.

About 30% of a home's heating energy is lost through windows. In cooling seasons, about 76% of sunlight that falls on standard double-pane windows enters to become heat.
Outdoor Temperature
We most often think that it's always better to open the windows when it's hot, but it's not. Sometimes, the air outside your home can even be warmer than the air inside your home. Opening the windows simply lets cool air escape and hot air to enter, resulting in hotter interiors.
Does light through a window count as direct or indirect? The light that passes through a window is considered indirect, as the rays will be diffused and won't have the same intensity. However, it depends on the window. If your window is south facing and there are no obstructions, it can be considered direct light.
What are examples of direct and indirect lighting?
The sun shines onto the lake and the trees, making the water look like it's shimmering and the leaves appear bright green. That's direct lighting. And though the trees cast shadows, sunlight still bounces off the ground and other trees, casting light on the shady area around you. That's indirect lighting.
Recessed lights
Recessed lamps are a natural option for niches in the ceiling or in the slots created on the counter ceiling to generate indirect and diffused light in all the room. The light source is hidden and the indirect illumination will be wrapping all the space without creating annoying glaring effects.
Can plants get enough light through light filtering shades? Absolutely, but it will depend on the specific type of plant. Choose a plant that has low light requirements or prefers some shade to give it the best chance. A plant that wants tons of sun may not be the best choice for a shaded window.
Whether during the Summer or Winter months, the sun's daily path starts in the East, swings South, and then sets in the West. Placing your plants in south-facing windows will expose them to day-long sunshine and help them grow as strong as possible!
While some window tints can reduce red- and blue-transmitted light, the majority of residential and commercial window tinting materials do not affect the spectrum of light plants need to grow.

South-facing windows receive the most light and are the hottest. North-facing windows receive the least light and are the weakest and coolest. East-facing windows receive light in the morning and are weak and cool. West-facing windows receive light in the afternoon and are strong and hot.
Shade. While it might seem counterintuitive, you can still get your daily dose of vitamin D without being in direct sunlight. When you sit in the shade, your skin is exposed to scattered UVB rays.
If you put your plants no more than 3-4 feet away from these lights, you'll get good results for “bright indirect light” type of plants. You might be able to support a few sun lovers right up close to the lights or if you put 4 lights together.
