<p>A greenhouse (10) which comprises two or more tiers in which the plants (33) to be grown are situated. The tiers of the greenhouse are of open construction without solid floor surfaces, which means that air and light are at least partly able to pass through the spaces (64) between the plants grown, from one tier to another. There are several plant growing lines (14) in the greenhouse, in which the plants are placed in growing carriages (12) moving on guide rails (29). The luminaires (31) are fixed to the underside of support beams (30) so that the light is also directed between the plants, support beams and guide rails onto the plants in the lower tier.</p> |
