The Primerus Products Spot-Spitter spray stake, formerly known as the Roberts Spitter, is the most efficient way to water nursery containers. The accurate spray pattern covers the entire root zone to optimize root development and water savings. Use the Spot-Spitter to irrigate your nursery, tree farm, garden center or recreational or medicinal grow. The Spot-Spitter Regular, Spot-Spitter Downspray and Spot-Spitter Tall are all in stock at GrowIrrigation.
Spot-Spitters are designed to work at 15-25 psi supply pressure. Use pressure regulators to be sure your system is in this range. Also use proper filtration to avoid clogging from dirty water. Use Primerus 1/8" Spaghetti Tubing to connect Spitters to your supply laterals. For more detailed information on the Spot-Spitter, see the following articles: Spot-Spitter FAQs, How to Use the Spot-Spitter and How to Design a Spot-Spitter System.
