How Many Garden Grids™ Can You Run At The Same Time?
A popular question! The amount of Garden Grids you can run simultaneously will vary based on your water supply's pressure and flow rate.
With common household water pressure of ~35PSI and unrestricted water flow from a standard-size garden hose, you can comfortably run about 5-6 4x4 Garden Grids at a moderate strength water stream (water streams spraying ~3-4"). With more pressure and volume, the number you can run simultaneously of course increases. We personally run 12 4x4 Garden Grids (the equivalent of 6 - 4x8s) in one of our own gardens on a 65 PSI supply.
You can endlessly interconnect Garden Grids with our multi-Garden Grid connection manifolds and custom-length garden hoses. If you do find that you can't run them all simultaneously, the manifolds, fortunately, allow you to control each Garden Grid independently from the rest. So, you can turn some on and some off and balance water output as needed.
Here's a quick video on output from the Garden Grid based on size and Connecting Hoses w/ The Garden Grid™ Manifold.
