Product details:

DIG earthline brown PC drip line consists of 100' & 250' of drip tubing with a 1-gph pressure compensating (PC) drip emitters built into the interior wall of the tubing every 18". each PC drip emitter consists of a cylinder with a labyrinth-like water passage, filter, & silicon diaphragm. Each PC drip emitter continuously adjusts to varying incoming water pressures ranging from 10 to 45 PSI, ensuring a constant flow rate regardless of any elevation along the line. In addition, the drip emitter's self-flushing mode allows particles to pass harmlessly through, providing reliable performance & a longer life. Earthline brown PC drip line can be used for all type of plantings, including ground cover, shrubs, loops around trees, for watering individual plants along the drip line, or for complete coverage of an area when multiple lines of drip line are placed with 16" to 24" between the lines. The drip line can also be used around a house foundation to reduce soil cracks. Earthline brown PC drip line can be used above the ground & covered with mulch.
