Led Vs Traditional Lighting

LED and traditional lighting systems (HPS/MH) represent different approaches to cultivating cannabis, each with distinct spectral outputs and energy profiles. Traditional high-pressure sodium (HPS) and metal halide (MH) bulbs have dominated cannabis cultivation for decades, producing broad spectral ranges with significant heat output. LED systems, developed more recently for horticulture, offer tunable spectra and reduced energy consumption, though cultivation outcomes depend heavily on spectrum design, wattage, and plant distance. Breeders and cultivators studying phenotype expression under different light sources have documented varying trichome development, internode spacing, and flowering timing. Understanding these lighting contexts is important for evaluating cultivation data, comparing grow reports, and understanding how environmental factors influence observable plant traits acro

Breeders conducting phenotype stability testing must account for lighting systems, as spectrum and intensity can influence morphology, resin production patterns, and development rates. Standardized lighting documentation helps ensure reproducible results when establishing cultivar characteristics across different growing environments.
