Led Vs Hps Profiles

LED and HPS (High-Pressure Sodium) lighting systems produce measurably different spectral outputs, which can influence terpene expression and volatile compound development in cannabis plants. HPS lighting, rich in far-red and infrared wavelengths, has historically been associated with certain aromatic profiles in traditional indoor cultivation. LED systems, with tunable spectral ranges and higher efficiency, allow growers to dial in specific light frequencies and may produce distinct terpene signatures depending on spectrum choice. These differences are primarily physiological responses to light quality rather than genetic changes. Understanding lighting-driven aroma variation is relevant for breeders developing cultivars optimized for specific growing environments.

Breeders increasingly evaluate how their lines express terpene profiles under different lighting regimes, particularly when developing cultivars for commercial indoor production. Documenting light-dependent aroma characteristics helps establish stable phenotypes across varied cultivation systems.
