Four Primary Hydroponic Growing Methods
 |
Ebb and Flow
Plant pots filled with growing medium The nutrient solution is pumped from the reservoir up into the garden
for a given period of time, the growing medium absorbs the nutrient
solution, and then the nutrient solution is allowed to drain away. |
 |
Drip System
to nutrient reservior |
The nutrient solution is dripped onto the growing medium on a timed basis providing the plants with fresh water, nutrients and oxygen. |

The plant roots develop in the grow channel. The top of the roots are exposed to air. The bottom of the roots are exposed to the nutrient solution. |
 |
Passive System
|
Although nearly maintenance free, most passive systems will have slower growth and development since there is no fresh oxygen brought into the root base. |
