摘要：
System for conditioning crops e.g. in a greenhouse (1), comprising climate control means for providing a local microclimate area (3) around the crop (2). First means (4) are provided close to the crop and arranged for local humidification (5) and simultaneous cooling or heating the local microclimate area. Second means (6) are provided close to the crop arranged for dehumidification (7a) and simultaneous cooling or heating the local microclimate area. The first means may comprise vapor outlets, creating vaporous climate, connected with means to provide that the vapor outlets remains in line with the growing crops. The second means comprise a duct system, e.g. with porous hoses or tubes, arranged to guide a hygroscopic liquid flow (7), arranged to absorb and remove either moisture or heat surplus. The degree of dehumidification or humidification can be controlled by varying the concentration and/or the temperature of the hygroscopic liquid.
