How Long Has Hydroponics Been Around?

Understanding the history of hydroponics can provide valuable insights and inspire modern enthusiasts. The early instances of hydroponic techniques date back thousands of years and spans various civilizations, including the Babylonians, Romans, the Ancient Far East, and the Aztecs.

600 BC: The Hanging Gardens of Babylon

One of the earliest examples of hydroponic systems can be traced back to the Hanging Gardens of Babylon, dating around 600 BC. These gardens were thought to have grown plants in a nutrient-rich solution rather than soil, relying on the water’s properties to support the plants’ growth. Created by King Nebuchadnezzar II as a gift to his wife, this wonder of the ancient world consisted of intricate watering systems that supported the massive gardens and are still studied by scholars and archaeologists today.

Ancient Egypt

Gardens that were surrounded by walls behind Egyptian residences are shown in ancient Egyptian hieroglyphs. There were various ponds in the gardens, and that water was utilized to water the plants. At that time, plants probably had sand and soil as their media.

The fish in the ponds were raised by the garden owner, who also enjoyed fishing in his own backyard. Lotus flowers, which were eaten by the Egyptians, were grown in the ponds. This kind of farming is an extremely old instance of aquaculture water being utilized to grow food since the water used for the garden was fertilized by the fish. This straightforward method pioneered the use of aquaculture fluids in hydroponics.

30 AD: Roman Emperor Tiberius

During the reign of Roman Emperor Tiberius, hydroponics played a role in satisfying the ruler’s year-round cucumber cravings. His gardeners cultivated cucumbers in transparent containers filled with water and nutrients. This method allowed the plants to receive both light and nutrients necessary for growth and is reminiscent of modern hydroponic techniques.

1100-1400 CE: Aztec Floating Gardens

The Aztecs demonstrated an ingenious adaptation of hydroponics in their floating gardens. Around 1100 AD, they built floating platforms called “chinampas” that allowed them to grow crops over shallow lakebeds.

Later in the 14th century, they created the famous Floating Gardens of Tenochtitlan — a system that allowed them to grow crops on the marshy land surrounding their capital. The Aztecs built rafts with reeds and soil, planting crops on top. The roots would then grow through the soil and into the water below, allowing the plants to receive the necessary nutrients for growth, creating a productive and efficient wick system.

1200s: The Ancient Far East

In the 1200s, the practice of hydroponics was employed in the ancient far east to cultivate rice. Farmers would plant rice seeds in flooded fields. The water provided the necessary nutrients and acted as a soil substitute, allowing the rice plants to grow strong and healthy.

Marco Polo visited China in the 13th century. He authored a book on his encounters with local culture and customs and it was one of the earliest records of hydroponics in the ancient far east. He mentioned hydroponics in rice production and gardening and observed platforms with “floating gardens”. He saw rice growing in structured water systems that aerated and nourished the roots. These hydroponic technologies, also utilized for other crops and fish production, amazed him.
