Wireless PAR Light Meter

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.
