Multi-Ducts are high-yielding complete hydroponic growing systems which enable growers to manage a large number of plants from one low-lying integrated reservoir - dramatically up-scaling the number of plants and yield, without increasing workload. Each Multi-Duct has long planting channels above its low-lying reservoir. Plants are placed in rockwool blocks onto the channels and the roots grow along the channels where they have unrestricted access to oxygen. Nutrient solution is constantly pumped up from the reservoir to the channel and flows over the roots of the plants. Whatever the plants don t use drains back into the reservoir ready to be passed over the roots again and the solution in the reservoir is emptied and replenished every 2-3 weeks to maintain a perfect balance of essential nutrient elements. The constant supply of water and nutrition to the roots combined with unlimited access to oxygen means growers find that plants are healthier, faster growing and produce up to 3 - 4x more yield than if growing using traditional soil methods.
