What is the Under Current® System?
The Under Current® Recirculating Deep Water Culture (RDWC) System features the patented Sub-Current Culture® circulation method. This high-performance water culture system is unmatched in efficiency, layout versatility and ease of use. The Under Current® utilizes negative water pressure to recirculate oxygenated nutrient solution through the plant’s root zone ensuring pH and EC levels are uniform throughout the entire system.
The Under Current® is the cornerstone of the CCH2O Proven Production Approach when used with Cultured Solutions® Nutrients and the CCH2O Nutrient Dosing System.
