National Geographic said “for plants exposed to playbacks of bee sounds (0.2 to 0.5 kilohertz) and similarly low-frequency sounds (0.05 to 1 kilohertz), the final analysis revealed an unmistakable response. Within three minutes of exposure to these recordings, sugar concentration in the plants increased from between 12 and 17 percent to 20 percent.”
Flowers hear buzzing of bees 0.2-0.5 kHz and increase sugar production.
I want to try this with Cannabis. Though the room would need to be acoustically designed so that the plant, person, audience in the room would actually be hearing that specific frequency.
