Why does sound effect plant growth?

Answer 1

1. For decades, people have been experimenting with music and plant growth. Many amateur plant growers claim that Classical Music works better than loud rock and roll and heavy metal. So far, scientific studies have not backed up this claim. No one has proven that plants prefer one kind of music to another.

2. Plants do like noise. Plants exposed to a set frequency of sound tend to germinate more quickly, grow taller and weigh more than those kept in silence. Both 50,000 hz ultrasound (above the human hearing range) and 5,000 hz sound seem to work. Therefore, there's a good chance that plants like any sound you might play for them, including music.

3. Plants also like good, attentive care. If you are playing music you like for a plant, it may lead you to take better care of it. You will be more likely to carefully water and feed the plant and make sure it has good light. It might look like the music helps the plant grow, when you are actually taking better care of it.

4. Plants like carbon dioxide. If you are standing by a plant, singing to it, it is going to absorb some carbon dioxide from your breath. This could help it to grow more quickly.
