Growing plants that uses sound called "Sonic Bloom".

There is a method for growing plants that uses sound called "Sonic Bloom".

Sonic Bloom is a unique combination sound and a specially formulated foliary spray. The special sound is made up of a harmonic frequencies that parallel bird song. These sounds stimulate the tiny pores on the plant leaves to open. When these pores, called stomata, are open, the plat is able to absorb up to 700% more nutrients.

Once the pores are opened, special nutrients are sprayed onto the plants. These nutrients are really the critical activating factor of Sonic Bloom. The nutrient was derived from seaweed and it contains over 100 trace minerals, amino acids, and naturally occurring growth hormones. The sound is a tool to increase the receptivity of this organic foliar spray.

It may be that rock or death metal happen to hit these notes that mimic birdsong more than other types of music? It could have an impact on the plants is they are sound sensitive like this. This is also a good reason not to use plants when doing this type of experiment.

P.S. Another interesting thing for the gardeners out there is to spread rock dust into the soil of your garden to revitalize the depleted soil. There is a group doing this somewhere or other (Google...) that have been getting plants to grow where they normally do not do well.
