Conserve water and time with drip irrigation! Arrow straight stake drip emitters with 24" tubing 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 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. Stakes come pre-assembled with tubing (24" length) and barb fitting to attach to your drip irrigation system's main water line.
