With zero power to our hydroponic system, gravity distributes the nutrient solution across the entire system, submerging the roots much like traditional deep water culture (DWC) systems which generally rely on air pumps running for 24 hours to aerate the solution.
We go about aerating our solution differently. More like a stream in nature that aerates through surface contact with the air through movement. We recirculate the inline pump variably to expose the roots directly to air. The side effect is nutrients are mixed without the need for stirring.
