The study looked at how different types of red and blue light affect the growth and photosynthesis of a plant called Anoectochilus roxburghii. They found that a mix of equal amounts of blue and red light helped the plant grow better and taller. White light made the plant grow more aboveground parts. Blue light made the plant's pores open more and increased water loss, but it didn't help with photosynthesis. More red light made the plant have less green pigment. Blue light had more green pigment.
