“Hydroponics is the art/science of growing plants in a soil-free environment. Historically, hydroponics isn’t that new. In fact, there are many ancient records of people using the concept of hydroponics to grow plants.
One such important record is the Hanging Gardens of Babylon, which is considered one of the Wonders of the Ancient World. In Babylon, they used gravel and stones to grow plants.
While the system is certainly more primitive than what we can create now using our own two hands, it’s important to note that the underlying principles remain the same.
This hydroponics guide will give you a bird’s eye view of how hydroponics works, how it actually grows plants and how you can start your own hydroponic system.”
