Claims23
A greenhouse comprising:
- transparent walls;
- and
- a structure including at least one ridge beam as part of a roof of the greenhouse,
- wherein the at least one ridge beam extends a distance above another part of the roof defines two elongated side zones present above the another part of the roof and at either side of the ridge beam,
- wherein the at least one ridge beam includes one or more elongated hollow spaces,
- wherein the at least one ridge beam is provided with one or more closable openings in both side zones, the one or more closable openings fluidly connecting the exterior of the greenhouse with the one or more elongated hollow spaces of the at least one ridge beam,
- wherein the at least one ridge beam is provided with one or more openings at its lower end fluidly connecting the interior of the greenhouse with the one or more elongated hollow spaces of the at least one ridge beam, and
- wherein the at least one ridge beam comprises an elongated valve and a fixed part, the valve being movable between at least (i) a first position relative to the fixed part, wherein the one or more closable openings in a first elongated side zone fluidly connecting the exterior of the greenhouse with the one or more elongated hollow spaces of the at least one ridge beam, and wherein the one or more closable openings in an opposite second elongated side zone are closed, and (ii) a second position relative to the fixed part wherein the one or more closable openings in the second elongated side zone fluidly connect the exterior of the greenhouse with the one or more elongated hollow spaces of the at least one ridge beam, and wherein the one or more closable openings in the first elongated side zone are closed.
