A method and a system for growing plants on multilayer principle in mobile gutter farming is described, whereby, in the process of growing plants planted in cultivation gutters, said plants are conveyed in cultivation layers present on top of each other in a cultivation space in a longitudinal direction of the cultivation space in one or opposite directions. The cultivation gutters and the plants contained therein, are treated in the cultivation space by means of a processing arrangement in a cultivation layer-specific manner, whereby the cultivation gutters and the plants contained therein are first of all conveyed by motion elements in each cultivation layer of the cultivation space in the longitudinal direction of the cultivation space in opposite directions and are treated by processing elements in each cultivation layer of the cultivation space separately, in a manner substantially independent of the other cultivation layers.

An open-top gutter for cultivation of plants. In an example, the open-top gutter includes a space limited by two side walls and a bottom wall and divided into trough-like compartments by at least one dividing wall. The dividing wall includes at least one water space formed by a double wall, open at the bottom of the gutter.

A system for decontaminating/neutralizing breathable air and surfaces in an occupied enclosed space, i.e., agricultural greenhouse, includes mounting an atmospheric hydroxyl radical generator along an inside surface of the atmospheric hydroxyl radical generator having respective opposite air inlets and air outlets. The hydroxyl radical generator includes a polygonal housing supporting a plurality of spaced crystal-spliced UV optics, which are tubular, medical grade pure quartz optics to emit/irradiate ultraviolet in the nanometer wavelength/ultraviolet spectrum of between 100 and 400 nanometers for deactivating and neutralizing atmospheric chemicals and pathogens in breathable air and surfaces. The hydroxyl radicals contact the walls of the reaction chamber housing. The hydroxyl radicals become created and excited to react quickly with impurities including VOC, virus, bacteria and fungi, rendering them inactivated and neutral. The breathable air passes through the polygonal housing and is decontaminated and neutralized of impurities before entering the occupied enclosed space.

Hydroponic systems for growing plants, and a corresponding process for line production of the hydroponic systems are provided.

A tray for a vertical growing system for growing plants having opposed first and second side walls, a first open end and second open end opposed to the first end defining a perimeter of the tray; and a raised region disposed within the perimeter of the tray wherein at least one side wall is configured with a downward sloping outer face to direct fluid from the tray to an adjacent gutter. The tray forms one side of an enclosed plenum which directs forced air to growing mediums supported by each tray via holes formed in each tray. A bottom side of the tray includes ribs and valleys exposed to an interior of the plenum where such ribs and valleys contribute to substantially constant air velocities emanating from each hole in each tray along an entire length of the plenum.

Hydroponic systems for growing plants, and a corresponding process for line production of the hydroponic systems are provided.
