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.
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.
