The BC1 spectrum contains light of every wavelength in the area of photosynthetically active radiation (PAR; 400-700 nm).
Blue light is widely responsible for improving the quality of plants - it favors the opening of the stomatal apparatus, which allows CO2 to enter the leaves and results in a higher photosynthesis efficiency.
In addition, the red light in the BC1 spectrum influences the regulation of plant growth and development.
The BC1 spectrum in rose cultivation increases stem height by 13%. The flowers increased in diameter and height by 19% and 23%, respectively, compared to plants grown under HPS lamps (Graph 3).
