Six Basic Hydroponic Systems
There are four basic methods of hydroponic or soilless gardening – active, passive, recovery, and non-recovery – and six basic hydroponic systems which each function differently, but in all cases the plants receive their nutrients via some form of water (hydro) delivery system: drip (recovery or non-recovery), wick, water culture, ebb and flow or flood and drain, nutrient film technique (NFT), or aeroponic.
Drip Growing Systems
One of the most common forms of hydroponics, recirculating or “recovery” drip growing systems recycle the excess nutrient solution from a reservoir. A timer controls a submersed pump which drips nutrient solution onto the base of each plant via a small drip line.
Maybe the simplest hydroponic system, the wick system involves no moving parts and can use a variety of growing media. In all cases the nutrient solution gets released onto the growing tray and delivered to the roots throug...
