What's The Flow Rate (GPM) Of The Garden Grid™?
The flow rate of the Garden Grid™ is adjustable 🙌 You can have the water streams coming out slowly (like drip irrigation) or quickly (full stream) by adjusting the handle on your water spigot, using a water flow valve, or adjusting the valves on our Garden Grid Manifolds (if using them). In general, at a moderate flow (streams roughly 3-4”) a 4x4 Garden Grid will have an output of about 1.5-2 gallons per minute. Here’s a quick video and a chart for all Garden Grid™ sizes. Also, here are tips on how long to water and how to check if you're watering enough.
