The focus is on general lighting conditions of three crops (cucumber, bamboo leaf, lettuce), and the main plant physiological parameters observed are soluble protein and sugar content, and root active absorption area. The results show that the use of filter film from March to May is beneficial to crop growth and can help to increase crop yield and improve crop quality. The multi-layer interference filter used does not only select red and blue light, but also also allows passage of the full spectrum diffuse sunlight (about 15% of the unfiltered light).
