Container or modular farms use hydroponics to grow plants indoors. Hydroponic farming is a method of growing plants in nutrient-rich water, not in soil.
There are many types of hydroponic farming systems like nutrient film technique (NFT), deep water culture (DWC), and ebb and flow. All these systems deliver nutrient-rich water to the plants in different ways and fit under the umbrella of hydroponic farming.
Some of these systems have a horizontal layout: plants grow how they would grow outdoors, parallel to the ground.
Some of these systems have a vertical layout: plants grow vertically stacked, perpendicular to the ground.
This isn’t to be confused with “vertical farming” - a broader term to describe growing more with less space by stacking plants. Vertical farming can include production methods other than hydroponics, such as aquaponics (involving the use of fish and other aquatic creatures to provide nutrients), aeroponics (growing plants in the air in a misty, humid environment), and also traditional soil growing.
A vertical, hydroponic farm is a farming system that uses hydroponic growing techniques and where the plants are stacked on top of each other to grow more with less space.
But they can be stacked in horizontal trays or in vertical towers.
It doesn’t matter because both stacking orientations will still be considered as “vertical farming” because they maximize indoor growing space.
