What is aeroponics?


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

This differs from hydroponics, where plant roots are submerged in a solution of water and nutrients.

In aeroponics, the roots have greater access to oxygen, which results in healthier plants, significantly faster crop growth rates and increased yields.

Growing plants with sound

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

At LettUs Grow, we use ultrasonic aeroponics. Ultrasonic technology is used 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 and increases the viability of using aeroponics in much larger, commercial growing spaces, where its impact is maximized.
