Vertical farming layer structure and method for vertical farming using the same

A method for vertical farming, the method comprising:

• providing a vertical farming layer structure as a single structure, the vertical farming layer structure comprising an underlying support, a light-reflective upper surface, and a plurality of light emitting devices;
• positioning a plurality of farmed plants on the underlying support;
• providing the light-reflective upper surface above and vertically aligned with the plurality of plants, the light-reflective upper surface being adapted to reflect light by diffuse reflection;
• emitting light from the plurality of light-emitting devices positioned between the underlying support and the light-reflective upper surface, the light being emitted from each light-emitting device along a respective optical axis oriented towards the light-reflective upper surface such that the light is at least partially diffusely reflected off of the light-reflective upper surface to reach the plants supported on the underlying support.
