Current Culture Under Current 4

Are you looking to maximize yields and reduce vegetative time?
Are you looking for a premium deep water hydroponic system?
Then look no further, Current Culture is truly in a class of its own!
The Under Current® system is the world’s only recirculating water culture hydroponic system to feature the 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.
