S
olution culture systems are often seen as the purest
form of hydroponics as plant roots are suspended
in nutrient-rich water and only a minimal amount of
substrate is used to support the plant. These types
of systems were also at the forefront of hydroponic
research and development in the earliest days of soilless
culture. During this time, the simplest solution culture
vessels were large glass jars of nutrient solution into
which air was bubbled. The plant was supported by
cardboard, cotton wool, or other materials at the top. Such
experiments demonstrated that plants did not require soil
or any other solid substrate to grow.
