You must know the differences of greenhouse and warehouse when choosing LED lighting. For greenhouse, the sunshine can get into the glass and its spectrum range is wide. So we just need to use 450nm and 660nm as fill in lighting.The spectrums of upper row are for growth stages of seedling,vegetative and flowering respectively. But for warehouse, there is no sunshine at all, so we need to add white because that its spectrum range is from 400 to 800nm which is important for nutrient diversity.
