Horticulture Spectrum Reference Guide

HORTICULTURE SPECTRUM REFERENCE GUIDE

Full spectrum white light provides useful light for photosynthesis across the 400 nm to 700 nm wavelengths, which is also referred to as Photosynthetic Active Radiation (PAR). Additional Far Red light (700 nm - 800 nm) influences plant growth and development (morphology). Full spectrum white light also provides comfortable lighting for workers within the space, which may allow growers to reduce or eliminate additional light sources within the growing space. /"!!#'!&%
