Let plants grow in a good light.
It’s basic botany—plants get the energy to grow from light through photosynthesis. But not just any light. Crops require a specific amount of light during a particular timeframe. The ideal light for plants comes from the wavelength known as the photosynthetically active radiation (PAR) spectrum. The ALTA® by Monnit PAR Light Meter monitors this spectral range (389 to 692 nanometers) from indoor and outdoor light sources, including LEDs.
The ALTA PAR Light Meter is a full-spectrum quantum device that measures PAR in photosynthetic photon flux density (PPFD). One of the two important light readings you receive from the PAR Light Meter is PPFD, indicated by micromoles per square meter per second (µmol/m2/s). The PPFD reading shows both light intensity and the amount of light that is on a square meter of crops each second.
Another critical reading from the PAR Light Meter that helps assess plant health is Daily Light Integral (DLI). The DLI measurement indicates the PAR level or PPFD accumulation that falls on a square meter of crops during 24 hours. It’s calculated in moles of light per square meter per day (mol/m2/d).
Monitoring with wireless PAR Light Meters, commercial growers, greenhouse staff, and grow house managers can simplify their smart agriculture operations, and:
