Under Current XXL13 - Current Culture

The Under Current™ XXL13 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, 3” UC Spin Tight Bulkheads, CCH2O 8" custom molded Lids with Port Hole, CCH2O 8" custom molded Net Pots, Danner Mag-Drive™ Return Pump, Air Force Pro ™ Air Pump, 9” Air Diffuser Disc, Medium Round Air Stones, Air Distribution Manifold, Air Hose, In-Line Filter, Adjustable Float Valve with Reservoir Adapter Kit, Drain Valve, Chiller Adapter, Garden Hose Drain Adapter, Cultured Solutions™ VEG A/B and 1-Year Warranty.
