![]() ![]() Plant leaves and stems tend to grow toward the light source.Pale, yellow, wilted, and fallen leaves.The distance between one leaf and another is farther apart (spread) because the plants grow to stretch to get more sunlight.Plant stems elongated and slender or called etiolation.Plant growth is stunted and weak because the photosynthesis process is not optimal.Leaf size is smaller than normal leaves.The signs of a plant suffering from a lack of light are as follows: The average intensity of light in rooms far from windows is less than 250 fc.įor plants that suffer from a lack of light, growth is not normal. ![]() Even the light in the room sometimes intensity (strength) can decrease to 500 fc or even lower. Meanwhile, indoors, the intensity of sunlight entering through windows or doors may be only around 2,000-5,000 fc. In fact, in the open, plants can obtain sunlight reaching 10,000-12,000 fc. Indoor ornamental plants generally only get a very limited amount of natural light through windows or doors. Several applications on iOS and Android-based phones also offer the ability to measure light intensity. To accurately measure the intensity of light, a measurement tool called a foot candlelight meter is used. One foot-candle is equivalent to 10.7639 lux. The unit of light intensity is also expressed in lux. ![]() A one-foot candle can be interpreted as the intensity of the flame of a candle (1 lumen) that is emitted, illuminating a surface of 30 square centimeters (1 square foot) as far as 30 cm (1 foot). Light intensity is measured using units of foot candles or abbreviated as fc. Light is the first factor that must be considered in caring for indoor ornamental plants (house plants). ![]()
