1. Plants will grow in boxes on a mechanical track that carries them from the top of the building to the bottom for harvesting 2. Mechanical arms below the track will gradually shift the boxes forward on each level 3. Leafy vegetables will be planted in the boxes in pumice to hold water. An irrigation line will carry water and nutrients to the roots.
