The Under Current Evolution 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.

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