Growing plants with sound – how LettUs Grow use ultrasonics in aeroponic growing systems ( With video ! )

Aeroponics is a method of growing plants without soil. Instead, roots are suspended in the air and irrigated with a nutrient-dense mist.

Aeroponics more commonly uses nozzles to generate mist. However, technical complexities and issues with maintenance have prevented aeroponics being successful in larger scale agricultural applications such as greenhouses.

At LettUs Grow, 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 removes the need for nozzles, therefore increasing the viability of using aeroponics in much larger, commercial growing spaces, where its impact is maximized.
