A plant growing environment comprises a greenhouse and a heating floor comprising a pool of heat conducting fluid contained in a sealed enclosure. The sealed enclosure has a top surface providing a soil-less substrate for growing plant in containers. A heat source is connected in heat exchange relationship with the pool of heat conducting fluid. A temperature sensor is provided for sensing the temperatu re (T1) inside the greenhouse. A control unit is coupled to the temperature sensor f or managing the operation of the heat source as a function of T1.
