One pair of Snip-n-Drip End Caps will help to customize the Snip-n-Drip irrigation system to fit your particular garden's needs. The end caps are inserted into the end of the soaker hose to cut off flow and force the water out, through the sides of the hose rather than out the end. Use these in conjunction with the Snip-n-Drip 3-Way Connector to expand the potential variations of this irrigation system. This system helps you get water where you want it, and avoids the poor economy of overhead watering. When you water the soil instead of the plants, you can avoid a bunch of foliar diseases.
