Built for Your Yard
At Harvesting Essentials, every system we carry is specified for real residential irrigation — zone-by-zone reliability, corrosion-resistant fittings, and controllers built to handle fault conditions before they become failures. We stock products we'd recommend to someone who needs it to run correctly from day one. Every order ships with tracking, and our return policy gives you 30 days if something isn't right.
Questions We Get a Lot
ET stands for evapotranspiration, a calculated value that reflects how much water your landscape is losing based on temperature, humidity, wind, and solar radiation. A controller that uses ET data adjusts each zone's run time automatically so the system delivers what the soil actually needs rather than running a fixed schedule regardless of conditions. This is the primary mechanism that prevents cumulative overwatering across a season.
Yes, provided the controller supports independent zone programming, which most multi-zone units in this collection do. Each zone can be assigned its own run time, frequency, and start window, which matters because drip emitters and rotary heads operate at different flow rates and require different run durations to deliver equivalent soil moisture. Mixing zone types on one controller is standard practice; the programming just needs to reflect the difference.
OTA stands for over-the-air firmware update, delivered through the controller's WiFi connection without any manual intervention. It means the manufacturer can push scheduling improvements, bug fixes, or new ET algorithm updates to your unit after purchase. For irrigation hardware that runs seasonally over several years, this keeps the controller current without requiring a hardware replacement.
Most orders ship free within the Continental U.S., excluding Alaska and Hawaii, per our standard shipping policy. If the unit does not work for your setup, you have 30 days to initiate a return under our Return Policy. We recommend confirming your valve wiring configuration and voltage requirements against the product specifications before purchasing, as compatibility depends on your existing valve type and the number of zones you need to control.
About Our Smart Sprinkler Controllers
A smart sprinkler controller is the decision-making hardware in any irrigation system. It determines when each zone opens, how long it runs, and whether conditions on a given day actually call for watering at all. Where a basic mechanical timer runs a fixed schedule regardless of rainfall or temperature, a WiFi-enabled controller with app scheduling or ET-based programming adjusts run times in response to real environmental data. The result is a system that applies water when and where it is needed, not simply when the clock says to. This category is suited to homeowners managing multiple zones across lawn areas, garden beds, and drip-irrigated plantings. The relevant specifications to evaluate are zone count, indoor or outdoor rating, voltage compatibility with your existing valves, and whether the unit supports fault alerts or OTA firmware upgrades. A controller rated for outdoor installation in a valve box is a different product from one designed for interior mounting, and that distinction matters before any wiring begins. Match the controller's zone capacity to your current layout with room to add one or two zones as your system grows.
