The EnGrow Pod system has been specifically designed to create optimal ventilation and allow for natural passive airflow of fresh oxygen to move underneath the soil through the Eco-Chamber. To achieve optimal airflow, the Eco-Chamber Fan can be added to the system to boost the delivery of fresh oxygen to the base of the living soil. Oxygen levels determine overall living soil and plant health. Maintaining the ideal level of oxygenation in living soil is vital for optimum growing and long-term regenerative soil development.
