• Enhanced Oxygen Exposure: The suspended roots absorb more oxygen, promoting robust growth.
• Space Optimization: Less space required compared to conventional methods.
• Reduced Resource Waste: Recapturing unused water and nutrients minimizes waste.

In a controlled grow room, the seedlings begin their life cycle without the need for soil. Plants are placed in net pots, and their roots dangle freely to absorb a fine mist rich in nutrients. These mists are delivered through various methods, including high-pressure and low-pressure aeroponics, or the more sophisticated ultrasonic fogger aeroponics.

The misting ensures that roots remain moist but not soaked, creating an environment where water droplets and moisture levels are precisely controlled. Simultaneously, lighting provides the energy needed for photosynthesis, while a regulated supply of CO2 ensures plants have the necessary gas for their growth.

Support systems, such as foam collars and sprinkler heads, keep plants secure while allowing for dispensing of nutrients. In high-pressure aeroponics, a reservoir houses the nutrient solution, which is then propelled towards the roots by specialized sprinkler heads to create a fine mist of water droplets. Meanwhile, **low-pressure setups often employ a cloner, producing a gentler mist for the young plants.

Through this sophisticated yet surprisingly straightforward method, plants can concentrate their energy on upward and outward development rather than expending it on extensive root systems. This leads to not only faster but also more potent plant growth, all without the environmental toll of traditional farming methods.
