I have been growing hydroponically for a few years and in preparation for growing tomatoes, basil and rosemary in the basement of the Patton Block building, i have decided to start collecting hydroponic information in one place.
The following is a list of "parts" that all hydroponics have in common:
Some additions:
- Air stones are used to "aerate" the nutrient solution when circulating pumps are not used.
Types of Hydroponics
This website has a nice description of 6 ways of growing plants in water.
Wick
This system uses no pumps, but instead uses a "wicking" system to move water from a water reservoir to the plant bed containing the support material.
Water Culture
This system is unique because the planting bed (made of some type of floating foam) sits/floats on top of the water reservoir. Since the planting bed and water reservoir are in direct contact, there is no need for a pump. Roots extend into the water reservoir.
Ebb and Flow (Flood & Drain)
As the name says, the planting bed is "flooded" with water and then allowed to "drain." This flood/drain process can be controlled by a timer on a pump, or better yet through the use of a siphon tube.
Drip (recovery or non-recovery)
Individual plants in the planting bed have their own drip tube that provides water/nutrient solution. Unlike the systems above, most drip systems do not use a planting bed, but instead individual planting containers. nutrient solution is "dripped" using a pump and timer.
