Common Hydroponic Techniques
DWC
• Plant roots are suspended in solution of
nutrient-rich, oxygenated water.
• Air pump runs 24-hours a day
• Simple Technique, rapid growth
Deep Water Culture
Flood & Drain
• Nutrient solution is made to alternately
flood and drain away from root section.
• Water aeration not as important
• Fairly Simple, Flexible
Flood & Drain
NFT
• Shallow stream of nutrient solution is recirculated around bare roots
• Continuous flow in channel
• Channel slope, length and flow rate are key
• Moderate complexity
• High yield, high quality, extended harvesting*
Nutrient Film Technique
Aeroponics
•
•
•
•
Plants are grown in a mist of nutrient solution
No growth medium required
Excellent oxygenation, fewer pathogens
Moderate-to-High complexity, depending on
approach
Aeroponics
Passive Wick
• Transfers nutrient solution via capillary action
• Constant supply of water to roots
• Simple, Inexpensive
Passive Wick
Commonality
Results May Vary
Productivity of techniques will
vary with crop, environment and
primary constraints .
All are valid and proven
• Many techniques share a
common set of elements
• E.g. If you have a DWC system,
you can convert to Flood and
Drain with minimal expense
To Learn is…. Fun
Explore, experiment and,
most of all, track your
experiences.
