Growing food indoors is usually limited by the space you have. More often than not, that means some kind of vertical placement, as we’ve seen withwindowfarms, mini-greenhouses doubling as lighting and aeroponic systems.
Fogponics — a more advanced application of aeroponics where vaporized water is used to transfer nutrients and oxygen to enclosed, suspended plant roots — is where German design company Vakant Design begins instead with Fogger, a unit designed to give plants that extra boost.
