Top furling automated retractable greenhouse cover is a retractable cover for a greenhouse that is mounted on top of the greenhouse. Top furling automated retractable greenhouse cover comprises: a spine clamp, a left furling cover assembly, a right furling cover assembly, a hinge pin assembly, and an electrical control box. Left and right furling assemblies each comprise a curtain or cover, a furling rod, a furling motor, and a support arm. Electrical control box sends electronic signals to cause left and right covers or curtains to furl above the greenhouse when retracted and to unfurl down to the ground when extended to cover the greenhouse. The top-mounted design allows efficient use of gravity to apply tension to the furled rolls.

The invention relates to a shading device (10) for a greenhouse (15), with a shading element (20) and at least one lighting element (50,50), wherein the shading element (20) comprises an outer side (21) and an inner side (22), the shading element (20) is formed from interwoven electrically conductive first thread elements (30,30) and electrically insulating second thread elements (40), the first thread element (30,30) comprises a reflective mean (33), reflecting an ambient light (60), the lighting element (50,50) is arranged at the inner side (22) of the shading element (20) and connected with the first thread element (30,30), and the lighting element (50,50) is driven by an electrical current, conducted by the first thread element (30,30), resulting in the emission of an artificial light (51), illuminating a plant (80) growing in the greenhouse (15).

A shading device for a greenhouse includes a shading element and at least one lighting element, wherein the shading element comprises an outer side and an inner side. The shading element is formed from interwoven electrically conductive first thread elements and electrically insulating second thread elements. The first and/or second thread elements each may be adapted for reflecting an ambient light. The lighting element(s) may be arranged at the inner side of the shading element and connected with the first thread elements, and the lighting element(s) may be driven by an electrical current, conducted by the first thread elements, resulting in the emission of an artificial light, which may illuminate a plant growing in the greenhouse.
