How Light Effects Plant Development

October 16, 2018

Overall plant growth and development depends not only on the spectrum of light received, but also on the color combination, color sequence, and duration of each. Plants have evolved to employ finely tuned sensors to use different spectrums of light for different stages of growth and reproduction.
