Hydroponics: A Brief Introduction
Hydroponics, is derived from the Greek words 'hydro' and 'ponics', meaning water working. In hydroponic gardening, plants are grown without using soil; instead nutrients are delivered via the plants' water supply.
There are many different commercial hydroponics systems, available in a variety size, form, and type of materials used. These systems use electric pumps for aeration (the process by which air is circulated through, mixed with or dissolved in a liquid or substance) and irrigation.
Most plant will grow well hydroponically. Hydroponic gardening is perfect for fruit bearing plants such as strawberries, tomatoes, cucumbers and peppers, and leafy crops, like lettuce and herbs. You can also grow flowers, though most people choose to grow the same crops in a hydroponic garden as they would in a soil garden.
On June 25, 2007, Chris Pirillo explained how he and his wife do hydroponic gardening using the Aerogarden system. Watch the Youtube video is embedded below.
