Multiple Garden Grids? Manifolds Link Them So They Water Together - Garden Grid Manifolds make it easy to connect all of your Garden Grids to a single water source even if they are in separate gardens. Single Manifolds are best for single Garden Grids, double manifolds are best for two Garden Grids that are side-by-side. Garden Grid Manifolds make it easy to connect all of your Garden Grids to single water source even if they are in separate gardens. Single Manifolds are best for single Garden Grids, double manifolds are best for two Garden Grids that are side-by-side. Connect Hoses From Manifold To Manifold – Use the capped port at the bottom of the manifold to attach a garden hose to link to another manifold for unlimited expansion and individual control of each Garden Grid - The number of Garden you can run simultaneously depends upon your water supply's PSI and flow rate. As a general guide, 60 PSI allows for 6 4x8 Garden Grids to run at once (equivalent of about 12-4x4s or 24 2x4 Garden Grids) Control Water Flow to Each Grid - Each manifold has valves so you can turn water on or off to each Garden Grid individually—no disconnecting or unhooking hoses required. Manifolds are designed and built in the USA* for long-lasting quality you can count on. Compatible With Any Garden Layout, Raised Beds, Elevated Planters, or Ground-Level Gardens - Water side-by-side beds or gardens spread across your yard. Just remove the cap and connect another manifold or Garden Grid with a GIM custom-length garden hose for easy expansion. How To Order – Get The Right Fit For Your Garden - Select the height nearest to your garden's height. Use a Single Manifold if your garden has one Garden Grid, or a Double Manifold if you're placing two Garden Grids side-by-side. For any raised garden bed over 20" tall, a manifold is recommended—even if you're not linking to other grids—so your hose connection isn’t left hanging mid-air. Choose the Lay-Flat option for ground-level gardens or if your hose connections are inside of your garden bed walls. Check the images and videos for setup examples. Garden Grid Manifolds make it simple to connect and run multiple Garden Grids from a single water source—whether in the same garden or across separate beds. With built-in valves for easy flow control and expandable connections to add more grids, they eliminate messy hoses and ensure efficient watering in every corner of your garden. Use the Single Manifold for a single Garden Grid and a Double Manifold for two Garden Grids that are next to each other in the same garden.
