The opposite. Try to push a weed in a windy wall at 30 m high If they use vertical farming to breed lattice they are just doing it wrong. There are much better

The opposite. Try to push a weed in a windy wall at 30 m high If they use vertical farming to breed lattice they are just doing it wrong. There are much better uses for that. Sun and rain are not so necessary as it seems. Many plants love shadow, and every building has a system to move water up and let it fall later. Green walls could gladly act as a first filter to help recycle part of the liquid human waste produced on a skyscrapper. We are yet diluting it before, so... why not modernize it adding a mesh of capillary roots in the way down? Putting this walls in special areas out of the way, even shadowed areas, is totally doable even in desertic areas. Just a matter of design. This walls would store water, boost biodiversity and generate a local climate.
