In order to cultivate high vegetables, herbs and ornamental plants all year round, artificial light is necessary in the winter months to ensure consistent quality. In addition to the right light intensity, the spectral light quality also plays a major role. Due to the increased proportion of blue light, the external and internal plant quality can be improved with luminaires that generate a light spectrum similar to sunlight. The growth becomes more compact and the leaf color and taste become more intense.
Conventional high-pressure sodium discharge lamps are still the most economical assimilation lamps and are suitable for almost all plant cultures.
