  • The Under Current System, 4 SITE MODEL 13 GALLON XXL

    The Under Current™ XXL13 System 4 

    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. 

    The Under Current™ XXL13 Includes: 13 gallon growth modules, 3"manifold, 8” centered Heavy Harvest lids with 8” Heavy Duty Net Pots, Danner Mag-Drive™ Return Pump, Danner Supreme Air™ Air Pump, 9” Air Diffuser Disc, Elite™ Air Stones, Air Distribution Manifold, Air Hose, Adjustable Float Valve with Reservoir Adapter Kit, Drain Valve, Chiller Adapter, Garden Hose Drain Adapter, and 1-Year Warranty.
