## Description

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.All Current Culture Systems now come with White ABS lids. These new white lids are made of durable ABS plastic, are UV stable, 100% non-translucent and highly reflective. This provides for slightly cooler system operating temperatures and less scale build up. The black lids previously used have been discontinued and are no longer available. New Side-Entry Air Ports All Current Culture Under Current system now include an innovative side-entry for the air diffuser lines utilizing a uni-seal for each module. This allows you to remove the entire module lid without disconnecting the air lines, making root-zone inspection much easier. Replacement Air Diffuser kits are now sold in two options - side entry or top entry. You can easily convert an older UC system with top entry to utilize side entry by purchasing an air diffuser kit and following the included instructions to drill the correct sized hole into your modules.
