Abstract: An apparatus for controlling conditions in a plant cultivation facility includes a lighting system arranged in connection with plants present in a cultivation facility. A hydronic cooling arrangement lowers or impedes the rise of temperature in the cultivation facility. The cooling arrangement has a cooling manifold present in connection with plants in the cultivation facility and a heat recovery arrangement for utilizing excess heat generated in the cultivation facility. The heat recovery arrangement includes a heat storing system. The heat recovery arrangement includes condenser dryers/coolers for collecting water and/or heat absorbed in the indoor air of a cultivation facility and a heat pump assembly for transferring the heat accumulated in the heat storing system into a secondary circuit independent, with respect to cooling arrangement's water circulation loops.

Abstract: 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.
