The Roberts Spot-Spitter, now made by Primerus Products, is the most efficient way to irrigate mid to large sized nursery containers. The accurate, miniature spray pattern gives full container coverage without overspray, resulting in optimal root development and water savings. A built in shutoff allows spray to easily be stopped when containers are sold.
The mini flow Grey Spitter has a 90 pattern and 3.0 GPH flow rate at 20 PSI designed for 1-3 gallon containers or 4-8" flower pots.
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 Tubingto connect Spitters to your supply laterals.
