DIG’s 300-series Adjustable Micro Sprayers are available with three different spray patterns that include full, half and quarter circle. They have an adjustable flow feature of 0 to 26.1 GPH at 25 PSI. The available models include 300B, 308B and 309B (packs of 2) with 10/32 thread, and 300-1B, 308-1B and 309-1B (packs of 1), fully assembled with a 13” stake, 12” PE riser and 1/4″ barb. These micro sprayers have an adjustable knob that allows control of flow to reduce or increase the diameter or wetting area of the spray pattern. Used for residential gardens, flowerbeds, groundcovers, shrubs and trees, the adjustable micro sprayers are ideal for areas where low-flow overhead irrigation is desired or for areas where drip emitters or conventional sprinkler systems are not practical.

The Adjustable Micro Sprayers are available with full-, half- and quarter-circle patterns with an adjustable flow knob that allows flow control from 0 to 26.1 GPH at 25 PSI. The flow control’s main feature is used to change the size of the wetting area with coverage that can reach up to a 10’ radius and 21’ full circle, depending on the assembly used and the height of the micro sprayers above ground. Using a PE riser extension, the height of the sprayer can be adjusted to fit taller plants and higher vegetation growth. The higher the position of the micro sprayers above the ground, the larger the wetted area will be. These micro sprayers are available with 10/32 thread or in a complete assembly with a 13” stake, 12” PE riser and 1/4″ barb for added flexibility in the installation. Use the micro sprayers when overhead watering is suggested on any type of planting, including vegetation that requires moisture, groundcovers, flowerbeds or individual trees along the poly tubing. The recommended spacing is 8’ to 12’ between the adjustable spray heads or one per tree to a maximum distance of 78′ to 108’ in length when the flow knob is completely open, using 1/2” drip tubing as the main lateral.
Like micro sprinklers, micro sprayers and jets are available in a wide variety of styles, flow rates, diameters and configurations. Like micro sprinklers, they operate at low pressure and require a filter to protect the small orifice of the sprayers from clogging. The main advantages of the adjustable micro sprayers are the lack of moving parts and the capability to adjust the flow and change the wetting area. The micro sprayers are an efficient and reliable method to apply water. To cover densely planted areas, place the micro sprayers close together in rectangular or triangular spacing for good overlapping irrigation and better uniformity. Do not use the micro sprayers in windy areas as the micro sprayers’ small size droplets can be easily dispersed in the air, even under low to moderate wind conditions, adversely affecting uniformity. The main advantage of low-flow micro irrigation is that a relatively large number of micro sprayers can operate simultaneously.
Basic installation recommendations for this product include first reviewing the area and then making a drawing of the garden or site with your preferred layout.
If automation is required, use one of DIG’s hose end timers or battery operated controllers. The ideal controller should have flexible scheduling and two to four start times per day for added flexibility.
Option one: Cut a length of two to four feet of 1/4” micro tubing (not to exceed four feet) (vinyl – models B38 for 50’ and B38100 for 100’, or poly – B38P for 50’ and B38100B for 100’). To the micro tubing end, insert a 1/4” barb (models H80A for pack of 10 and H80B for pack of 50). To the other end of the micro tubing, thread the micro sprayer and clip it to a clip stake (model R66). Insert the clip stake to the ground, keeping the micro sprayer head at a minimum of six to eight inches above ground for best coverage. Punch a hole into the drip tubing using the small punch (model D44) or the gun punch (model 16-035), and snap the 1/4” barb at the end of the micro tubing into the drip tubing.
Option two: To install the 10/32 thread micro sprayer, punch a hole in the upper side of the drip tubing using the small punch (model D44) or the gun punch (model 16-035), snap the 1/4” barb at the end of the 6” PE riser assembly (model P34B) into the drip tubing and thread the spray head into the PE riser.
Option three: To install the complete assembly micro sprayer, punch a hole in the side of the drip tubing using the small punch (model D44) or the gun punch (model 16-035), snap the 1/4” barb at the end of the 24” micro tubing assembly into the drip tubing and insert the stake to the ground, keeping the micro sprayer head at a minimum of six to eight inches above ground for best coverage.
