And the way it works is that there's a pump at the bottom, which periodically sends some of this liquid nutrient solution up to the top, which then trickles down through plants' root systems that are suspended in clay pellets -- so there's no dirt involved.
Funcţionează cu ajutorul unei pompe, la bază, care trimite periodic lichid hrănitor la vârf, care se prelinge apoi prin sistemul de rădăcini al plantelor suspendate în granule de argilă - deci nu implică răsaduri de pământ.
