Light is the most important factor, along with water, to grow healthy plants. Many species of plants will thrive in lower soil or survive without fertilizer, but without light no plant can live for long.
A fundamental aspect of life at this plant is the remarkable ability of plants to turn sunlight into energy. Sunlight is transformed through plants into usable energy, which is then used by animals who are consumed regularly by other animals as the energy travels through the food chain.

When it comes to indoor plant growth, gardeners usually struggle for adequate light or more reliable light. It’s important to note that natural sunlight coming through a window isn’t as intense as outside sunlight, and the light intensity decreases rapidly as the plant moves from the window further.
A simple push away from a window of 2 or 3 feet will minimize light intensity by more than 50 per cent. Thus indoor plants need to be by a window.
Also, it is important to pay attention to the direction that a window faces to gage the strength of light that comes in. The light intensity comparative to window orientation in Europe and North America, and most of Asia, is as follows:
Windows toward the north.
Such windows tend to have the lowest light intensity, and are mostly in the room in fairly dark shadow. Shade-loving plants may be able to thrive in a north-facing window during the summer months, but these windows are typically not conducive to plant growth in the winter.
Windows faced south.
Plants put in unblocked southern windows usually get the lightest.
Windows face to the east
East windows take advantage of the morning sun, when the rays are not as intense. Sometimes eastern windows are ideal for plants that only need moderate sunshine, or morning sunshine. As there are many ways to grow plants without light.
Windows faced to the west
West windows get the full afternoon and evening sun which in summer can be shockingly powerful. Even if they don’t have the same light intensity as southern exposures, a western-facing window is a perfect location for your sun-loving plants.
However, with that said, it is still likely to burn plants which are put near to windows as the window glass will act as a magnifying glass and the plant may not be well acclimatized to direct sun on its leaves. In the end, the best guide for the optimal light intensity of your plants is the plant itself.
Look out for signs of too much light, like yellowing leaves or burnt spots, or too little light, with leggy growth included.
