TL;DR
Deep Water Culture (DWC) is a hydroponic growing method where plant roots are suspended in oxygenated nutrient solution. This provides constant access to water, nutrients, and oxygen, supporting fast growth with minimal daily maintenance.

What Is Deep Water Culture (DWC)?
Deep Water Culture is one of the most widely used hydroponic systems. Plants are grown with their roots submerged in a nutrient solution that is continuously oxygenated using air stones or diffusers.
Because plants have constant access to water and nutrients, DWC systems reduce the need for manual watering and allow for consistent, controlled growth in indoor environments.
Constant nutrient access: Roots are continuously supplied with water and nutrients
High oxygen availability: Oxygenated solution supports healthy root development
Low maintenance: No daily watering once the system is running
Fast growth rates: Stable root conditions support efficient plant uptake
Scalable systems: Suitable for small grows and larger recirculating setups
