The most commonly used type of grow box is the so called “deep water culture” or DWC hydroponic systems. These are very popular because they can be set up and run with minimal technical skills, they are very efficient in terms of light and space utilization and they are easy to maintain. They also provide a great variety of different plants in a very simple way.
Pros: Very cheap and easy to setup and run.
However, the disadvantage of these systems is that they are not very efficient in terms of light and space utilization.
