: Removing soil eliminates soil-borne pathogens and pests, allowing energy to be spent purely on growth. Physical and Chemical Dynamics
: A very shallow stream of water containing all the dissolved nutrients recirculates past the bare roots of plants in watertight gullies. Soilless Culture: Theory and Practice
The theoretical foundation of soilless culture revolves around maximizing plant genetic potential by eliminating the variable and often restrictive chemical and physical properties of natural soil. The Constrained Root System
These systems use inert or organic solid materials to anchor the plant and hold moisture and nutrients. [PDF] Soilless Culture: Theory and Practice by Michael
: Roots are suspended in a dark chamber and periodically misted with a fine, high-pressure nutrient solution. 2. Substrate Culture Systems
: To compensate for limited space, the medium must provide a hyper-efficient supply of oxygen, water, and ions. The Constrained Root System These systems use inert
: Roots in soilless systems occupy a fraction of the space compared to field soil.
