The Under Current ™

Under Current models have 18" Plant Centers (the distance from the center of one plant to the center of the plant next to it) and 8 gallon Growth Modules that allow 2-4 ft of growth. The UC Standard models come in a 2 row format that are great for tents/huts & narrow spaces, and only require one row of horizontal lamps.

The Under Current is the worlds first re-circulating Water Culture Hydroponic System featuring our Patent Pending Sub-Current Culture™ Method.  This innovative application circulates literally hundreds of gallons of solution per hour beneath plant roots.

The Under Current™ supercharges the solution with dissolved oxygen, creating a hyper aerobic condition. Constant, 24/7 nutrient circulation ensures that pH and EC are uniform throughout the entire system. An inline Danner Mag-Drive pump provides peripheral negative pressure by thrusting nutrients back to a return module (Epicenter). From this point the solution is drawn from module to subsequent module, evoking perpetual fluid motion.
