Types of Systems
Water Culture Systems
Water culture systems include the nutrient film technique, aeroponics, and the aeration method.
The nutrient film technique uses a plastic duct or tubeas the container through which a constant, thin film of nutrient solution flows. Plants are suspended through holes in the top of the duct. The duct is gently sloped so gravity pulls the solutionback to the nutrient reserv. There are many variations of this system, making it the most popular for the home gardening.

Aeroponics is the growing of plants in a container in which theroots are suspended in a nutrient mist rather than in a solution. The most popular container for aeroponics is an enclosed A-frame or triangled frame constructed of styrofoam boards. The plants areplaced in holes along the inclined sides of the frame. The nutrient mist is delivered to the roots by a vaporizer. The mist reaches the roots. Any excess runs down the inside of the frame, is collectedat the bottom, and is recycled back to the nutrient reserv.

The aeration method, one of the first systems to be developed, uses an aquarium air pump to bubble oxygen to the roots ofplants immersed in the nutrient solution. Plants are suspended 1 inch above the solution by a 2-inch-deep net tray that is set into the container by placing the lip of the tray over the edge of thecontainer. A layer of inert material, such as gravel, clay pebbles, or vermiculite, is placed in the tray to provide stability for the plants while allowing the roots to grow down into the nutrientsolution.

Aggregate Systems
Aggregate systems use some form of inert material to support and surround plant roots. The most common materials used are rockwool, clay pebbles, gravel,perlite, vermiculite, sand, or foam chips. The media provides plant support, allows good oxygen filtration to the roots, yet, it retains a thin layer of nutrients and water around the roots. One of the...
