Although all methods have a different
approach to actually growing plants, the most
important difference between them is the method
of filtration that both the NFT and DWC units utilize compared with the media bed
method. The following text describes this method of filtration for NFT and DWC
units in detail. Afterwards, the NFT and DWC methods are discussed individually.
The general layout of this section begins with water flow dynamics, or how the water
moves through the system. Then filtration methods are discussed, followed by specific
planting guidelines for NFT systems.
