What Determines This?

When it comes to water distribution, volume is crucial. Volume depends on the water supply’s pressure (PSI) and the diameter of the distribution item. Most homes have a PSI of 35-70, and hose spigots usually have a 1/2″ or 3/4″ pipe. Connecting something that is a smaller diameter line to your hose spigot, will reduce the maximum water volume for your garden. For example, standard garden hoses are 5/8″ in diameter, providing nearly 57% more volume than a 1/2″ irrigation line.

Accessories like timers, in-line filters, and pressure reducers can decrease volume. High-flow timers or those without a narrow connector are preferable. In-line filters and pressure reducers reduce PSI and volume and they’re not necessary or recommended for use with the Garden Grid™. The Garden Grid™ comes with a built-in water filter screen to keep debris out and is designed to work with various PSI ranges, eliminating the need for extra components.

How Many Garden Grids™ We We Run In Our Garden?

Our garden has a 3/4″ water supply line, with 65 PSI, going into a hose spigot, with our custom-length garden hoses attached. With this setup, we are able to comfortably run (5) 4×8 Garden Grids™ and (4) 2×8 Garden Grids™ with a moderate strength water stream (~3-4″ water streams) all at the same time.

How Many Garden Grids™ Can You Run At Once?

Since there are a few variables to consider, we conservatively say that with 35PSI going to a standard-size garden hose, without anything restricting water flow, you can comfortably run 5-6 4×4 Garden Grids™ at the same time or the equivalent 2-3 4×8 Garden Grids™.

With a 65PSI supply, going to a standard-size garden hose, without anything that is restricting water flow, you can comfortably run 11-12 4×4 Garden Grids™ at the same time or the equivalent 5-6 4×8 Garden Grids™.

What Should You Do If Your Water Supply Can’t Run All Of Your Garden Grids™?

Simple! Group them into the amount of Garden Grids™ that your water supply can support and turn each group on individually. Using something like our 2-way or 4-way hose splitters makes doing this easier. Or, you can simplify further by using a multi-port garden hose timer to automate the groups turning on.
