<p>The glasshouse (1) has a vertical tubular envelope (2) including an open lower surface (3) permitting introduction of a plant inside the envelope, and an open upper surface (4) permitting access to the plant from an exterior of the glasshouse. Closing units i.e. movable flaps (5, 6), close the open upper surface. The flaps cooperate with each other based on upper and lower closing positions in which the flaps are extended to an exterior and an interior of the envelope for permitting and limiting the circulation of controlled air in the glasshouse, respectively.</p> |
