Achieve superior water distribution and protect your delicate seedlings with the Netafim SpinNet Micro-Sprinkler. Engineered specifically for overhead greenhouse and nursery applications, the SpinNet delivers highly uniform, rain-like droplets that ensure even coverage and dramatically improve seed germination rates. Unlike traditional overhead sprinklers that continue to leak after the water is turned off, this model features a built-in check valve assembly that instantly prevents drainage upon system shutdown. To install, simply suspend the sprinkler from your overhead 1/2" mainline tubing using the required Micro-Sprinkler/Fogger Hanging Assembly.
Review the exact performance metrics to integrate the SpinNet into your overhead system.

Build your overhead greenhouse irrigation system correctly to ensure drip-free operation.
Step 1: Prep the Overhead Mainline
Using a DripWorks key punch, create a clean hole in your suspended 1/2-inch or 3/4-inch poly mainline tubing directly above your growing tables.
Step 2: Attach the Hanging Assembly
Insert the barb of your Micro-Sprinkler/Fogger Hanging Assembly firmly into the punched hole in the mainline tubing. A hanging assembly with a stabilizing weight is required to keep the sprinkler plumb.
Step 3: Connect the SpinNet
Press the Netafim SpinNet Micro-Sprinkler securely onto the bottom female connection of the Hanging Assembly.
Step 4: Regulate Pressure & Filter
Ensure your water source has a 120-mesh filter installed to prevent clogging, and a pressure regulator maintaining pressure between 29 and 44 PSI so the check valve operates correctly.
Is the Netafim SpinNet Micro-Sprinkler good for spring greenhouse seed germination?
Yes, the Netafim SpinNet is perfect for spring germination. It delivers highly uniform water droplets that provide consistent coverage without washing away delicate seeds or soil in your greenhouse trays.
Its "bridge-less" design ensures there are no dry blind spots in the spray pattern, guaranteeing every cell in your seedling trays receives equal moisture.
How does the check valve on the Netafim SpinNet prevent water damage?
The built-in check valve immediately stops water flow when system pressure drops. This prevents the sprinkler from dripping onto plants below after shutoff, protecting them from overwatering and fungal diseases.
What pressure is required to operate the Netafim SpinNet Micro-Sprinkler?
The Netafim SpinNet requires an operating pressure between 29 and 44 PSI. The check valve needs this minimum pressure to open, so a pressure regulator is highly recommended.
How do I hang the Netafim SpinNet in my nursery?
You must use a Micro-Sprinkler/Fogger Hanging Assembly. This assembly connects the SpinNet directly to your overhead 1/2-inch or 3/4-inch poly mainline tubing.
