METHOD AND SYSTEM FOR GROWING PLANTS

In a method for growing plants in a controlled environment, a first plant is positioned in a first controlled environment (12) and a second plant is positioned in a second controlled environment 16). In order to lower an energy-consumption, the method comprises - during a first time period, providing a day-time lighting condition in the first controlled environment (12) and nighttime lighting condition in the second controlled environment (16); - during a second time period, providing the night-time lighting condition in the first controlled environment (12) and the daytime lighting condition in the second controlled environment (16); and - exchanging heat between the first controlled environment and the second controlled environment for controlling a temperature in the first controlled environment and a temperature in the second controlled environment. The first time period and the second time period are alternated. Thus, for example, during daytime, heat is received from sunlight in the first environment (12) and the heat may be spread through both the first and the second controlled environment (16). Further, for example, during nighttime, lighting is provided in the second environment for generating a daytime lighting condition, thereby generating heat, which heat may be spread through both environments (12,16). The present invention further provides a construction configured for performing the method.
