Recirculating Deep Water Culture – RDWC
Under Current systems offer a simple-to-operate irrigation pproach, well-
suited for applications ranging from CEA indoor to sun-grown greenhouses. RDWC
systems recirculate oxygenated nutrient solution through the plant’s root zone
24/7 ensuring pH, EC and temperature levels are uniform throughout the system
during the growing cycle. This approach results in unmatched productivity,
efficiency, and ease of use, and is ideal for integration with automation and
fertigation systems for commercial standardization.
