The daily light integral (DLI) is the number of photosynthetically active photons (photons in the PAR range) accumulated in a square meter over the course of a day. It is a function of photosynthetic light intensity and duration (day length) and is usually expressed as moles of light (mol photons) per square meter (m −2) per day (d −1), or: mol·m −2 ·d −1.
Ficus plant grown under a white LED grow light. A grow light is an electric light that can help plants grow. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated (typically a varying combination of red and blue light, which generally appears pink to purple to the human eye).
Houseplants which survive in conditions similar to a homeowner's living space will have a higher probability of survival. Tropical houseplants which grow under high thresholds of heat, for instance, will grow sun leaves which contain fewer chloroplasts. Plants which grow in the shade will grow shade leaves, containing more chloroplasts.
Most red light gets absorbed by the shade-intolerant canopy plants, but more of the far-red light penetrates the canopy, reaching the understorey. The shade-tolerant plants found here are capable of photosynthesis using light at such wavelengths. [citation needed] The situation with respect to nutrients is often different in shade and sun.
