Growing Indoor Plants with Success | UGA Cooperative Extension

Light intensity: Plants under high light transpire more water compared with plants under low light. Improper watering causes many problems. Containers with saucers may cause an excessive build-up of soluble salts (from the applied fertilizer). High levels of soluble salts can cause damage to plant roots and a decline in growth.

Light Intensity in Plant Growth and Development

The intensity of light is usually measured by the units lux (lx) and footcandle (fc). One footcandle means the degree of illumination 1 foot away from a lighted standardized wax candle; 100 footcandles is 1 foot away from 100 candles that are lighted simultaneously. Lux (pl. luces) is the unit of illumination that a surface receives one meter away from a light source.
