A greenhouse watering system for area coverage
Nursery benches. Protected crops. Even coverage.
A greenhouse micro sprinkler system distributes droplets across a growing area. It can suit nursery benches, closely arranged trays and planted beds where overhead watering is appropriate. The crop, growing medium and tolerance of wet foliage determine whether that method fits.
For widely spaced pots, a large share of an overhead application can miss the growing medium. Direct drip outlets may be more practical in that situation. Plan separate zones when young trays, established plants and container crops need different schedules or watering methods.
Plan the details
Good choices start with your layout.
Match water delivery, component connections and operating conditions before choosing quantities.
Select sprinkler spacing from the coverage pattern
A quoted spray radius describes reach under stated test conditions; it is not a guarantee that one sprinkler will water every point inside that circle equally. Use the selected manufacturer’s spacing and distribution data to plan overlap at the intended mounting height and pressure.
Map bench edges, walkways, end walls, fans, structural posts and hanging crops before laying out the supply pipe. Air movement and physical obstructions can redirect or block droplets. Check the installed pattern with catch containers across the crop area and compare collected amounts after the same timed run.
- Choose the nozzle and rotor combination before setting final spacing.
- Allow for the greenhouse edges and corners in the layout.
- Test at crop height and repeat when the canopy changes.
- Correct uneven coverage before extending the watering time.
Match every part of the hanging assembly
An overhead arrangement may use a distribution pipe, flexible drop tube, stabilizer and a sprinkler intended for inverted mounting. A compatible anti-drain valve can limit discharge after shutdown. These are model-specific choices: an upright-only sprinkler should not be assumed to work correctly when hung upside down.
Netafim’s SpinNet documentation is one example of a manufacturer specifying the drop tube, stabilizer and anti-drain components together. Use that principle when comparing a system, while taking actual sizes, pressure and filtration requirements from the product you select in this store.
Size the supply for the sprinklers running together
Sum the rated flow of all sprinklers that run together, then check the supply and the losses through filters, valves, pipes and elevation changes. As a planning example, 12 sprinklers delivering 40 litres per hour each require 480 litres per hour, or 8 litres per minute. These are illustrative numbers, not specifications for a listed product.
Select filtration from the water analysis and the nozzle requirement. Choose regulation that works at the zone’s real flow. A pressure gauge near the supply does not replace checking the furthest operating sprinkler, especially when another zone is drawing water at the same time.
Choose micro sprinklers or misting by purpose
A micro sprinkler is generally chosen to deposit water on the crop area. A fogger or fine-mist system may instead be selected for humidity management, cooling or propagation. Droplet characteristics, water quality, control strategy and the crop’s requirements determine which equipment is suitable.
Do not choose a nozzle solely because both systems are drawn above plants. Check whether your objective is to replenish root-zone moisture or manage the air around the crop. Where both are needed, separate control makes it possible to respond to each purpose without automatically applying more water to the growing medium.

Set up. Check. Keep growing.
Commission coverage, then fine-tune watering
Keep a record of your first working setup.
Check growing-medium moisture, crop stage and greenhouse conditions before running a zone. When overhead watering is appropriate, account for how long leaves remain wet and how ventilation and timing affect drying. A timer is a control tool, not a substitute for crop inspection.
During routine checks, inspect filters, blocked nozzles, damaged rotors, uneven drops and leakage after shutdown. Compare catch-container results when coverage changes. Clean or replace parts following the selected manufacturer’s instructions, then recheck the pattern before assuming the problem is solved.
- Prepare: flush lines and confirm each hanging assembly is compatible.
- Test: compare coverage and inspect drainage after shutdown.
- Adjust: set watering from crop moisture and repeat the coverage check.

Questions before you choose?
Start with these practical answers, then check the specifications of the parts you plan to use.
Talk to our teamWhat spacing should greenhouse micro sprinklers use?
Use the spacing data for the exact nozzle, rotor, mounting height and pressure. Test the installed pattern with catch containers across the growing area. Maximum spray diameter alone is insufficient to set uniform spacing.
Can any micro sprinkler be installed upside down?
Choose a model specified for inverted mounting and match its drop tube, stabilizer and other assembly parts. The operating pattern and drainage behavior can change when a sprinkler is installed in a position it was not designed for.
Why does water drip after the zone switches off?
Water retained in pipes and drop tubes can drain through outlets. Check the installation and whether a compatible anti-drain assembly is specified. A faulty seal or incorrect opening pressure may also need attention.
Is a greenhouse sprinkler system the same as a misting system?
The functions differ. Sprinkler irrigation delivers water to the growing area; a misting or fogging system may serve propagation, cooling or humidity control. Select droplet performance, controls and water treatment for the intended application.
