Drip Fitting Sizing: How to Know if the Tubing and Fittings are Compatible
Mar 24th 2026
When you are managing hundreds of pots, inconsistent watering isn't just an inconvenience—it impacts your bottom line. The Large Nursery Irrigation Kit is the ultimate high-capacity solution designed to automatically water up to 16 tables with 8 pots per table (128 pots total) across two independent watering zones. To handle this volume, we've upgraded the system's core to robust 3/4" Mainline Tubing, ensuring that water pressure remains strong and consistent from the very first pot to the last.
This professional-grade DIY kit provides commercial growers and serious hobbyists with unmatched flexibility. It utilizes pressure-compensating Octa-Bubblers as manifolds, which guarantee an equal maximum flow rate to all connected lines. At the plant level, the individual Pot Stream Sprayers can be adjusted for different pot sizes or shut off completely when inventory is moved or sold. Our commercial-grade "Easy Loc" fittings require no glue, allowing you to reconfigure your layout as your nursery changes.
We have pre-calculated all the components so you never have to guess what parts fit together. Just snap the parts in place and turn on the water. The included High Flow Hose Y makes splitting your layout into two manageable zones simple. Because this system is designed for high-volume commercial use, we strongly recommend pairing it with a High Flow Timer to fully automate your watering cycles without restricting the necessary water volume.
This high-capacity system connects to a standard outdoor hose faucet.
Step 1: The Header (Faucet Assembly)
Screw the Filter directly onto your faucet (or timer), then attach the 20 PSI Pressure Regulator, and finally attach the High Flow Hose Y. Connect the two 3/4" Easy Loc Female Hose Starts to the dual outlets of the Hose Y. This creates your two high-capacity watering zones.
Step 2: Lay the 3/4" Mainline
Run the 3/4" Mainline Tubing from the Hose Starts along your nursery benches. The larger 3/4" tubing reduces friction loss over long runs. Use the 3/4" Easy Loc Tees and Elbows to route the tubing. Close the ends of the lines with the 3/4" Easy Loc End Caps.
Step 3: Connect the OctaBubblers
Use the 3/4" Easy Loc x 1/2" Female Pipe Tees and the PVC nipples to splice the Octa-Bubblers seamlessly into the mainline. Next, connect individual lengths of 1/4" micro tubing to the eight active ports on each Octa-Bubbler.
Step 4: Place the Emitters
At the end of the 1/4" Micro Tubing inside each pot, attach your Pot Stream Sprayer. Push the stake into the soil near the root zone. Adjust the individual flow on the sprayer as needed for each plant's specific requirements.

Why does this kit use 3/4" tubing?
Standard 1/2" tubing can run out of flow capacity when trying to water 128 pots simultaneously. Upgrading to 3/4" Mainline ensures that the water pressure remains consistent across all 16 tables in your nursery setup.
Can I connect this to a timer?
Absolutely. However, because this is a high-capacity system, we strongly recommend using a High Flow Timer. Standard residential hose timers often restrict water flow, which could reduce the performance of the system.
How do I adjust the watering?
The OctaBubblers ensure equal pressure distribution. At the pot level, you simply twist the cap on the Pot Stream Sprayer to open the flow for larger pots, restrict it for smaller seedlings, or shut it off completely if a pot is removed.
Is it expandable?
This kit is designed to maximize the output of a standard commercial or high-flow residential faucet across two zones. While you can alter the layout, adding significantly more pots may require splitting your operation into additional, entirely separate watering zones with their own timers to maintain adequate pressure.
"Time saved watering"
"This large kit has really made raising my pots of Bonsai trees and flows so much easier. The ability to turn off individual sprayers is exactly what I needed when plants sell."
- Tom
"Essential upgrade"
"We were using standard 1/2 inch tubing before and the pots at the end of the greenhouse were barely getting a trickle. Upgrading to this kit with the 3/4 inch mainline solved all our pressure issues instantly."
- Michael R., Commercial Grower
