Do hydroponics save space in cities?

Yes, hydroponics can save space in cities as it allows plants to be grown vertically in a small area. With the use of hydroponics, plants can be grown in towers or other vertical systems, which can be placed in tight spaces, thus saving space. Additionally, hydroponics eliminates the need for soil, which takes up space and allows more plants to be grown in a smaller area. This makes hydroponics ideal for urban gardening, where space is limited.
