Music & Plants

Have you ever heard that music can affect plant growth?
Many scientists have done experiments regarding this. Dorothy Retallack used 3 laboratories containing the same species of plants. She used different types of music for each lab. The plants in the laboratory where music was played daily for 3 hours a day grew twice as large and became twice as healthy as those in a music-free environment. On the other hand, plants in the laboratory where music was played for eight hours a day died within two weeks.

Dorothy Retallack also tried experimenting with different types of music. She played rock music to one group of plants and soothing music to another. The group that heard rock turned out to be sickly and small whereas the other group grew large and healthy. What's more surprising is that the group of plants listening to the soothing music grew bending towards the radio just as they bend towards the sunlight!

Although music is not an absolutely proven factor in plant development, several studies have aided the musical development theory. Some relates this to how music (eg. classical music) affects the human brain positively. So basically, the effect on music on plants can be drastic; noisy music will only make the plants grow feeble and sick. Play classical music (Bach, beethoven, chopin) to make your plant grow better. Even if it isn't classical music, I believe, just soothing music will have the same effect.

If you want to try this experiment yourself, follow the steps here: http://www.freesciencefairproject.com/projects/plants_music.html
So basically, just expose plants to 2 different type of music : rock and classical.
See the difference for yourself.
