Full Question: I have to ask the question, have you read any info on this topic. After reading, I have come to the conclusion that maybe the guard cells of the stomata complex are being stimulated, at the hertz frequencies between 3000- 5000. Used inconjunction with a foliar feed spray, maybe somthing high in possasium ions(Some type of ionic water stimulator) to to induce uptake of nutrients. I, for one, try not to make assumptions without proof. I will be testing Dan carlson's product (sonic bloom) out, starting 1st of may. Please write back and disprove me with science. Thanks matty Response: Sonic Bloom has some ingredients that definitely can increase plant growth, such as mineral nutrients and the plant hormone gibberellin. However, the claim that certain sounds will open stomata wider does not seem to have any scientific validity. If you look on the Sonic Bloom webpage, they show two pictures of a stoma and claim that the Sonic Bloom treated stoma is open further than the untreated one. However, the untreated stoma is clearly open wider. If certain sounds could make stomata open wider, then real scientists would run experiments to confirm it and publish the results in scientific journals. To do a scientific test of Sonic Bloom, you would need to apply Sonic Bloom to two identical groups of plants under identical environmental conditions. Then one group would be exposed to the sound and the other kept quiet. The plant growth would have to be measured and statistically analysed. I have not seen that kind of research. If you examine the list of articles on the Sonic Bloom website, you find that none are from scientific journals, but are stories and interviews from popular magazines, newsletters, and newspapers. That is not scientific evidence. Real scientific evidence on the effectiveness of Sonic Bloom or the ability of certain sounds to make stomata open wider would be published in refereed scientific journals such as "Science" or "Plant Physiology." I am a plant physiologist, and a lot of the claims made on the Sonic Bloom website do not agree with scientific concepts of plant growth. For example, the website claims that stomata normally suck up trace elements in morning dew. However, virtually all trace elements are absorbed by the roots, not via stomata. Research by actual scientists with music/audio effects on plants has found no beneficial effects. References Sonic Bloom website" Science Projects on Music and Sound
