Greenhouse Micro-Spray Irrigation: It’s Use
Micro-spray is a cross between surface spray irrigation and drip irrigation. It has some of the advantages and some of the disadvantages of each type of irrigation. Like drip irrigation, micro-spray is considered a type of low-pressure irrigation typically operating with pressures between 15 and 30 psi. It is generally considered low volume with application rates of 5 to 70 gallons per hour (gph) (18.9 Lph to 264 Lph). Micro-spray typically creates a larger wetted area then drip irrigation making it well suited for irrigating ground covers, large flowerbeds and sandy soil.
Micro-spray is delivered through micro tubing to a series of nozzles attached to risers. These risers may be fixed or designed to pop-up. In either case, it is easy to see that they are functioning, eliminating the most commonly voiced complaint about drip irrigation.
Greenhouse Micro-Spray: Factors to consider
Greenhouse Micro Spray systems provide many of the same benefits as drip irrigation with a few exceptions:
• It is less likely to be exempt from watering restrictions because it puts out a higher volume of water than drip irrigation
• It is subject to evaporative losses and spray pattern disruption in windy conditions
• Higher flow rates make it more susceptible to overwatering and runoff
• Larger wetted areas may result in more weeds
