In ancient Egypt, kitchens were an integral part of the household, and they too incorporated built-in indoor gardens and hydroponic systems. The Egyptians were skilled in the art of agriculture and used their knowledge to create self-sustaining kitchen gardens. These gardens were designed to provide a constant supply of fresh herbs, vegetables, and fruits. The hydroponic system used in Egyptian kitchens involved growing plants in nutrient-rich water without the need for soil. This innovative approach allowed the Egyptians to grow a variety of crops all year round, ensuring a steady food supply for their households.
