Ideal for irrigating containers. Ingenious device that provides three standard flow rates and a 4.75" stake in one unit. Three flow tips deliver low (4.8 gph), medium (7.8 gph) and high (10.8 gph) flows at 10 psi. To install, insert one flow tip into the end of 1/8" poly distribution tubing and connect the 1/8" tubing to .5" poly tubing with the 1/8" barbed coupler. Push the stake into individual containers, field grown stock or potted plants on your deck. Each flow tip produces an even, flat spray, ideal for consistent application of water and nutrients. Spray pattern size can be adjusted by changing the depth the stake is pushed into the soil. To turn off individual Tri-Tips, simply place the spiked tip into the end of your feeder tubing.
