Conserve water and time! Arrow straight stake drip irrigation emitters put water where you need it and reduces water and fertilizer waste. The barbed stakes hold in place once inserted into the soil in a pot or basket. The drip irrigation stakes flow at a ½ gallon of water per hour. Straight stakes work best when running off an overhead water supply line commonly used in hanging baskets. Angled stakes work best when the water supply line is on the ground or bench height. Drip irrigation stakes come pre-assembled with tubing (36" length) and barb fitting to attach to the drip irrigation main water line.
