I am just curious if anyone has done or seen vertical farming that looks more like crops on a wall that is either completely vertical or close to it. I think that there is a good possibility that crops that grow tall could grow on such a surface and that doing things this way could make vertical farming of them practical. Most vertical farming that I see uses stacked grow beds and I think that should be called stacked farming to differentiate it from growing things on a vertical surface.
The only thing I’ve seen are wall gardens which are usually more for decorative plants than crops. Have seen an herb garden grown like that. If you search for “wall gardens” it will return a lot of results. Some of those techniques might amenable to crop type plants.
