The Under Current UC8 is the perfect 8-site hydroponics system for growers with limited space. Using the patented CCH2O Sub-Current Culture system, a variation of the traditional DWC hydroponics system, the Under Current UC8 provides constant plant nutrient circulation that delivers outstanding growth and big results.
Easy and reliable, no timers, no guesswork. Reduces labor & maintenance.
Greenhouse grade heavy-duty construction, water level marks, recessed drain wells, raised body for thermal cooling, and a smooth interior for easy cleaning.
The Under Current system is the world’s only recirculating water culture hydroponic system to feature CCH2O’s patented Sub-Current Culture circulation method.
Sub-Current Culture 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.
CCH2O 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.
*Boneless Spacing Option: All Under Current systems are available in a “Boneless” configuration. Boneless systems ship WITHOUT straight sections of piping allowing for custom plant spacing.
*Remote Epicenter Option: All Under Current systems are available with a “Remote Epicenter” option. This allows growers to place the Epicenter (control module) on the outside of their grow space or tent.
*Please note: Both of the above-noted options require the separate purchase and installation of PVC pipe.
