A line, system, and method are provided for delivering a plurality of fluids to a target plant array at a plurality of pressures. The line comprises a plurality of tubes at least portions of which are hydrophilic. The tubes are connected together to form a co-extensive, multi-chambered delivery system. Each tube is connectable at a proximal end to a source of fluid, preferably comprising at least two different fluids. By having a unitary system positioned in the soil, redundancy of equipment, labor, and systems can be reduced, with the instant system able to perform the functions of multiple systems.
