A system for growing crops includes a plurality of growing troughs with intake regions for receiving a nutrient solution and drains for releasing run-off of the nutrient solution. A nutrient circulation system with circulation subsections provides the nutrient solution to crops in the growing troughs. For each circulation subsection a piping arrangement with pipe outlets distributes the nutrient solution from a reservoir to the intake regions of a first subset of the growing troughs, and collects the nutrient solution from the drains of a non-identical second subset of the growing troughs in a drainage arrangement. The nutrient solution follows a flow path circulating through the reservoirs. The flow paths to the pipe outlets are sequentially split for equivalent flow impedance through each of the flow paths. A conveyor system moves the growing troughs from a planting location to a harvesting location and periodically increases the spacing between adjacent growing troughs. |
