The Under Current system is the world’s only recirculating water culture hydroponic system to feature the patented Sub-Current Culture circulation method. The Under Current is cornerstone of the CCH2O Proven Production Approach when used with Cultured Solutions® Nutrients and the CCH2O Nutrient Dosing System.

Sub-Current Culture (SCC) technology utilizes negative water pressure to recirculate highly oxygenated nutrient solution through the plant’s root zone. This continuous fluid motion supercharges the nutrients with dissolved oxygen, creating hyper-aerobic conditions perfect for explosive plant growth.

Constant 24/7 nutrient circulation ensures pH and EC levels are uniform throughout the entire system.

This unique water culture application is unprecedented in layout versatility and ease of use. The Under Current consistently delivers awe-inspiring yields for any sized application, from hobby to commercial greenhouse.
