Red is The Answer!

Thanks to those of you who voted in the current poll question and answered through a comment.  RED is the correct answer and that's what conclusion my buddy, Miss C came to also!  So her experiment worked!  Whew!  Red and blue are the best for plant growth and green is the worst.  Green light is least effective for plants as they reflect green light and absorb none.  It is this reflected light that makes them appear green to us.  Here are the results of her experiment.  The six plants grown under red light were 3.3" average in length.  The eight plants grew under clear or white light and were 2.6875" in length.  The five green plants grew 1.8" average in length.  Blue light is primarily responsible for vegetative growth or leaf growth.  Red light, when combined with blue light, encourages flowering.  Fluorescent, or cool white, light is high in the blue range.  Fluorescent lights are great for starting seedlings which we all will be doing soon!  So that's your botany lesson for today.  I'll think of a new poll question soon or if you have one you need an answer to, let me know! Talk to you later.
