FAQ About Indoor Plant Light Intensity Measurements

What are foot-candles and lux in the context of plant lighting?

Foot-candles and lux are units of measurement for light intensity. One foot-candle is equivalent to the amount of light a standard candle emits one foot away. Lux is the metric unit, with one lux equal to one lumen per square meter. For indoor plants, understanding these measurements helps assess how much light your plants are actually receiving.
