 Compared to other hydroponic techniques, such as NFT, deep water culture is relatively inexpensive to set up and can be easily reproduced by a home grower.Since there is a relatively large reservoir of nutrient rich water for each plant, there is buffering for pH, EC, and temperature, meaning those elements of the systems won’t fluctuate as fast as they might in an NFT system.Most hobby growers use Deep Water Culture (DWC).
