Vertical farming has become increasingly popular in recent years, thanks to its efficient use of space, resources, and energy. While the term "vertical farm" is commonly used to describe this innovative method of agricultural production, there are several other words and phrases that can be used to refer to the same concept. Some common synonyms for vertical farm include sky farm, vertical agriculture, vertical greenhouse, multi-level farm, and stacked farm. These terms all refer to a farming system that utilizes stacked layers or tiers to grow crops in a controlled indoor environment, often using techniques like hydroponics or aeroponics to conserve water and maximize crop yields.
