For closely spaced beds, choose drip-emitter lines; for widely spaced plants, use individual drip-emitters. flow rates of the emitters that you are planning to use and compare with the maximum flow rates for the different types of 1/4" tubing (page 14). For plants that need extra water, insert 1.0 and 2.0 GPH spot watering emitters, branching from main ½" tubing lines to reach trees, potted plants or other targeted areas.
