11CCH2O Under Current RDWC hydroponics system how it works

The patented Under Current® RDWC Hydroponics System is recognized as the gold standard for hydroponic crop production.

The most proven and widely utilized Recirculating Deep Water Culture hydroponic system in the world, the Under Current® is renowned for producing the very highest quality fruits, flowers, and essential oil profiles.

This unique, high-performance water culture system utilizes negative water pressure to recirculate oxygenated nutrient solution through the plant’s root zone. Requiring no timers, the 24/7 circulation and aeration encourages rapid root growth and ensures pH and EC levels are uniform throughout the entire system.

Highly regarded for its unparalleled growth rates and record-setting yields, the Under Current® is simple to operate and well suited for residential, professional and commercial facility applications.

Improve Productivity and Quality With Reduced Labor

The patented Under Current® is ideal for integration with automation and fertigation systems for commercial standardization. It is Current Culture H2O’s proprietary method to circulate oxygenated nutrient solution throughout the root zone.

This approach ensures pH and EC levels are uniform during the growing cycle, resulting in unmatched productivity, efficiency, and ease of use.

    Seth

  • “I was given this by a friend. Once I run out, I will definitely be buying more of this product. I don’t have anything to compare it to, as this is my first grow, but this is the only nutrient made for flowering that I used, and it seemed to really help but some mass on the buds in the last few weeks.”

    Dan

  • “Worked good, kept my buckets and roots clean. Ran out half way through the grow though and switched to H2O2 instead.”
