What is the Under Current® System?

The Under Current® system is the world’s only recirculating water culture hydroponic system to feature our patented Sub-Current Culture® circulation method.

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.

Our 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.

 

Under Current® System Features

Modular Design
• Multiple growth module sizes and plant spacing options
• Easy to set up, break down and expand
• 60+ system configurations to suit any size plant and grow space
• Designed to accommodate a wide variety of lighting footprints

Premium Construction
• Highest quality commercial and greenhouse caliber components
• CCH2O’s proprietary parts are designed and manufactured in California
• Systems utilize professional grade air and water pumps

Under Current® System Options

Boneless Spacing*: All Under Current® systems are available in a “Boneless” configuration. Boneless systems ship WITHOUT straight sections of piping allowing for custom plant spacing.
