Hydroponics in History Part 1: Ancient Hydroponics
Let’s take a break, for a moment, from the more information-heavy blogs, shall we? I want to take a look at the history of the way we grow things around here. How did hydroponic systems develop? Who started this whole thing? Check it out: hydroponic gardening has been around a lot longer than you think!
The science of hydroponics started about three hundred years ago, when people began to experiment with plants’ abilities to absorb water-soluble nutrients and to thrive in soilless conditions. By the mid 1800’s, there was a whole sector of scientists trying out hydroponic methods, called “solution culture”, back then. Wikipedia says that hydroponic experiments were first documented in 1627, with the book Sylva Sylvarum by Francis Bacon. But Wikipedia does not know all! There has been other, much earlier evidence of water gardening. We will be reviewing the history of soilless gardening in three parts, going chronologically. Begin Part One:
There is lots of evidence that growing plants in water dates back to much, much earlier than just a few hundred years ago. The Egyptians, Inca Indian tribes, the Aztecs, and the ancient Babylonians all practiced hydroponic gardening, without ever calling it such. There are mentions of cultivating plants directly in water in Egyptian records dating back to the time of the New Kingdom and the “Woman-King,” Pharoah Hatshepsut around 1460 BCE. Various experiments were undertaken by Theophrastus (372-287 B.C.), while several writings of Dioscorides on botany dating from the first century A.D., are still in existence. So people were well aware of what sort of nutrients were needed to produce crops and flowers and the role that water could play in that process.
The Hanging Gardens of Babylon was considered one of the seven wonders of the ancient world and one of the first recorded examples of water gardening. It was built on the banks of the Euphrates River circa 600 B.C. Stories, from Greek poets and historians of the day, tell of lofty rock walls containing the royal gardens of King Nebuchadnezzar II. They were deprived of water, in that parched land (in present-day Iraq), so they had to rig a system to get the water from the Euphrates to the top of the Hanging Gardens. They constructed a water pulley (also known as a chain pump) to gather the water from the river and pooled it on top of the garden. Historians believe the chain pump was set up with two large wheels on top of each other with a chain hung to connect them. Buckets were attached to the chain and the whole system rotated to bring water from the river up to the gardens. There, it is said that the wonder never ceased: waterfalls, fountains and pools overflowing with fresh water, in which grew many types of exotic trees, flowers and grasses. A tropical paradise of luxury in the middle of the desert.
However, the Aztecs were true hydroponic pioneers who grew crops on rafts woven out of reeds and roots, on the edge of lakes. When they were driven off of their land, in the 11th and 12th centuries, they settled on the shores of Lake Tenochtitlan (and others) in Mexico, where it was too marshy to grow the traditional way. So, they developed an ingenious, revolutionary way to grow crops in the water! The lake shores were stocked with mineral-rich deposits that were used to nourish the food they grew on the water. The floating rafts that they constructed where often attached together to form entire floating fields- the size of islands- on which they grew everything they needed to sustain themselves. Plant roots grew through the rafts, made of natural fibers, and dangled into the water, sucking in everything they needed from the nutritious lake water. Aztec decedents still cultivate some of these floating gardens near Mexico City today, in a long-standing tradition.
