Plants are unique.
Spectrums should be too.

Daylight Spectral Distribution

PBAR refers to Plant Biologically Active Radiation and designates the spectral range from 280–800 nm. According to the American Society of Agricultural and Biological Engineering (ASABE), PBAR covers a more substantial range of light that affects plant biology. The PBAR measurement includes the PAR band from 400–700 nm as well as the ultraviolet radiation band of 280–400 nm and the infrared radiation band of 700–800 nm. Active Grow uses the latest spectrometer technology to see a lamp’s entire PBAR range.

CRI <70

Active Grow LED CRI >95

The Color Rendering Index (CRI) measures a light source’s ability to accurately reproduce the colors of objects in comparison to natural sunlight (CRI 100). This 100-point scale examines 15 different R values of a light source and uses the average of R1-R8 to calculate the CRI value. Traditional grow light sources typically have low CRI values and may create uncomfortable working environments. Poor color reproduction also makes it difficult for growers to visually identify issues with plants like pests and fungus.

Traditional HPS Spectrum CRI <25

Active Grow Entrourage Spectrum CRI 94
