How it works: Plants have evolved with the broad spectrum of light wavelengths provided by natural sunlight. With traditional HPS and Metal Halide lighting, red and blue wavelengths are enhanced to promote different growth stages such as vegetative and flowering. Whilst this is beneficial, plants grown under a full spectrum throughout their growth cycle benefit from a more natural quality of light proven to prevent stretching and encourage higher quality growth. Daylight spectrum also allows a more natural formation of branch internodes (less far apart) for increased plant mass.
