Abstract (en)

[origin: EP0355703A2] Method and apparatus for improving a life supporting environment by utilizing the exhaled ingredients of living plants comprising closely cultivating plants within a given space, exposing the plants to light and adding a nutritious substance to the plants, heating the atmosphere in the given space to a temperature range of 25 DEG C to 35 DEG C to stimulate the physiological action of the plants so that the discharge of exhaled substances from the plants is increased, and furnishing the exhaled ingredients-containing air obtained to a human living space within a building.
