I first put this in a book I wrote in 1990. What inspired me then and now is that the whole technology is based on the fact that the early morning singing of birds trigger plants to open their stomata–infinitesimal mouth-like pores that allow oxygen and water to pass out of the leaf while carbon dioxide and other gases move in to be transformed by photosynthesis into sugars. The music of nature, it seems, is vital to healthy plants. Sonic Bloom is an organic spray that is applied to the leaves of plants along with the specific sound frequency that induces stomata to open. The results are amazing.
