Drip Irrigation Micro Sprayer 1/2" FNPT Base - Greenhouse / Nursery

by DIG



Micro Sprayer Series 038

Designed for use in greenhouses, DIG's 52-038-xx micro sprayers produce fine droplets and come in a wide range of flow rates. They are deal for maintaining conditions conducive to propagation and germination. An optional anti-leak device prevents dripping at the beginning and the end of each irrigation cycle, keeping the entire line pressurized.


  • Use for germination, seeding and rooting in greenhouses and nurseries
  • Use for overhead irrigation, propagation and cooling in greenhouses and nurseries


  • Maintains constant humidity or cooling in greenhouses
  • High uniformity due to distribution accuracy and low precipitation rate


  • Excellent performance with uniform water distribution
  • Color-coded nozzles for flow rate identification
  • Modular design allows for a wide range of interchangeable components
  • Suitable for upright and inverted position
