And the way it works is that there's a pump at the bottom, which periodically sends 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.
a način na koji radi je da postoji pumpa na dnu koja periodički šalje neke hranjive otopine do vrha koja tada kaplje dolje kroz sustav korijenja biljke koje je postavljeno u glinenim kuglicama -- tako da zemlja nije uključena.
