LettUs Grow with sound – ultrasonic aeroponics increase growth rate
By growing plants with ultrasonics and water instead of soil, LettUs Grow has doubled growth rates compared to conventional hydroponic systems. Ultrasonic technology is harnessed to create high-frequency sound waves that shake water, until it disperses into lots of tiny droplets, like a mist. This mist can be distributed and controlled to provide the exact amount of water and nutrients to plant roots depending on their needs and stage of growth.
