This invention relates to a screen manufactured according to a weaving or knitting process comprising a number of screen elements (1) which, in an operational position, may be installed at respective intermediate distances away from one another, these intermediate distances being changeable - for instance, by the use of elastic threads or bands - in order to adjust the degree of screening of the screen. According to this invention, the screen elements (1) extend according to the direction of production (P) of the screen. <??>A method for carrying out a climatization in a space, such as, for instance, a greenhouse in which plants are cultivated, at least the air humidity and/or the air circulation and/or the concentration of CO2 in that space being regulated, by adjusting the intermediate distances between the different screen elements (1) of a screen covering this space at least partly. A similar regulation occurs in a very simple and efficient manner, without any harmful effects to the plants <IMAGE> |
