Each manifold includes both an inlet and an outlet for garden hoses.

To connect separate gardens, attach a hose to the outlet (the capped end) of one manifold and run it to your next garden. From there, connect it to the inlet of another manifold or directly to a Garden Grid™.

You’ll need a manifold if you’re linking multiple Garden Grids™ together.

For raised beds taller than 15", we recommend using a manifold regardless to support the hose connection and reduce strain on your Garden Grid™ connector (which is about 13.5" long). It’s not required, but it helps keep everything aligned and supported.

Use a Single Manifold for one Garden Grid™.

Use a Double Manifold for two Garden Grids™ positioned side-by-side.

No. If you’re using a single Garden Grid™ and don’t plan to connect additional beds, you can attach your garden hose directly to it.

However, for raised beds taller than 15", we recommend using a manifold to help support the hose connection and reduce strain on the Garden Grid™ connector.

A manifold also keeps the setup tidier and makes expansion easy if you decide to add more Garden Grids™ later.

It depends on your water pressure, hose length, and layout.

Watch the video below for real-world examples and tips.

Yes! You can supply the Garden Grid™ with nearly any water source—as long as you have the right connection. Most gardeners use a standard garden hose from a spigot, but the Garden Grid™ can also be fed from an existing sprinkler or irrigation system.

As long as your sprinkler or irrigation line has a garden hose thread adapter (a common part at most hardware stores), you can run a hose straight to the Garden Grid™—or connect directly at the adapter. From there, water flow is easy to control using a simple valve or one of our Garden Grid™ manifolds with a built-in valve, keeping everything simple, visible, and easy to adjust.

Each manifold includes individual shutoff valves for every Garden Grid™ connection.

You can adjust the flow or turn water off to one Garden Grid™ while others continue watering — giving you simple, at-the-bed control without walking back to the spigot.

Hose length depends on your manifold setup.

Double Manifold

The manifold sits centered between the two side-by-side Garden Grids™.

Measure from the middle point between those Garden Grids™ to wherever your hose needs to reach.

Single Manifold

The manifold sits at the end (corner) of the Garden Grid™.

However, if you rotate the Garden Grid™ water feed tube to point toward the middle of the Garden Grid, the manifold will sit about 30" from the end of the Garden Grid™.

Measure from the final manifold position to where your hose needs to go. See below for examples.

Yes. You can use any standard hose timer at your spigot, then run your hose to the Garden Grid™ Manifold as usual. The timer controls when water turns on and off, while the manifold lets you control flow to each connected Garden Grid™ individually.

For the best fit with your GIM™ watering setup, we recommend a GIM™ Automatic Hose Timer. It’s built for higher flow and secure brass hose connections, helping keep watering simple, reliable, and easy to control.

Yes. However, like any watering component, we recommend disconnecting and draining manifolds in freezing conditions.

No. Manifolds use standard garden hose thread connections and seal properly when hand-tightened.

Proposition 65 is a California law that requires warnings on products if they contain trace amounts of certain substances listed by the State of California. These warning thresholds are often much lower than limits set by federal or international health agencies, and the law applies only in California.

A Proposition 65 warning does not mean a product is unsafe. It is intended to provide information so California consumers can make informed purchasing decisions.

You may see Proposition 65 warnings on a wide range of everyday products in California, including building materials, hardware, furniture, packaged foods, and household items.

⚠ WARNING: This product contains a chemical known to the State of California to cause cancer or birth defects.

Does this apply outside California?

No. Proposition 65 applies only to products sold in California. Customers outside California may still see this notice for transparency and consistency across our website.
