The ancient Romans were known for their advanced engineering and innovative architecture. In some wealthy Roman households, kitchens were equipped with built-in indoor gardens and hydroponic systems. These gardens allowed the Romans to grow fresh herbs, vegetables, and even fruits right in their kitchens. The hydroponic system used a combination of water, nutrients, and artificial lighting to provide the plants with everything they needed to thrive. This not only provided a convenient source of fresh produce but also added a touch of natural beauty to the kitchen space.
