You are here: Home / Hydroponics


It may sound complicated to become a hydroponic grower, however, actually with the right guidance and patience hydroponics can produce more food per square metre than you think. You can do this growing higher quality produce, in a faster time while being located in the middle of your city. Hydroponics is a great solution for food production and is becoming more and more popular primarily because of its efficiency. One of the main advantages of hydroponics is that it can solve the problem of food loss due to external environmental catastrophes! And, unlike many people think, it can be as nutritious as food grown in soil because nutrition is a matter of balancing your nutrients and feeding these properly to your growing crops.

This section provides an introduction to the knowledge necessary to enter into the wonderful world of hydroponics. And if you are interested in what you learn, then I can assure you that there is more science to be explored with this.

What you can learn

In the links to learn section you can get a basic introduction and understanding of hydroponics. There is information about the different parts of the hydroponic system and the different types of hydroponic systems. There are also videos covering this learning.

The measurement section will help you understand what you need to know about PH levels; nutrient and water solutions; water temperature and oxygen; substrate and growing medium. There are also videos covering this learning.

If you want to learn how to build a DIY hydroponics system, look at professional models and see how hydroponics works in industrial greenhouses then we have that covered too.
