An irrigation controller that reads your soil and waters only when it's actually dry — not on a Sunday schedule. Plus fertigation that meters nutrients and verifies the line EC before and after each dose. Built by a grower who got tired of guessing.
Two founder-operated New Jersey gardens. Six zones each. Eight crops. A predecessor controller running soil-moisture-only logic. The numbers below are our own season-by-season observations — informal, but real, and the reason we built this. Production HydroIQ adds live weather data to the scheduling model and EC-verified fertigation; cloud-side per-zone learning that tunes schedules over time is in development.
Outdoor watering is the biggest controllable use of water in most American homes — and up to half of it never reaches a plant, lost to wind, evaporation, and runoff from timers that don't know it rained. HydroIQ waters to what the soil actually needs, zone by zone — cutting irrigation use by around 20% in our early deployments while keeping plants thriving.
Day-of-week watering caps are now routine from Nevada to New Jersey, and Nevada and California have made decorative-turf bans permanent. Watering to actual soil need — not a fixed clock — is how a landscape stays healthy inside whatever your district allows, on the water that's actually available.
Sources: U.S. EPA WaterSense; NOAA / NIDIS (U.S. Drought Monitor); World Resources Institute Aqueduct 4.0. HydroIQ's ~20% reflects our alpha gardens and the published soil-moisture-control literature (EPA cites at least 20% for soil-moisture-based control). Production results will be measured and published quarterly from beta.
No marketing-speak. Here's the actual sequence the box runs, every day, on every zone.
Soil moisture, nutrient level (EC), temperature, and pH — at multiple depths per zone — sampled every 15 minutes by industrial-grade probes.
Compares the live read to your crop's water need at its current growth stage — using the established crop-science standard (FAO-56). No Sunday-at-6am schedules. Manual override any time.
Optional Bloom fertigation channel meters cartridge nutrients while measuring the line EC before and after each dose, so a silent injection failure or wrong cartridge is caught and flagged. (Full closed-loop dose control is on the roadmap.) In-line pH sensing for fertigation is planned, not yet shipping. No mixing buckets, no monthly tank chemistry.
An optional camera (planned, coming with the cloud subscription) will capture several stills a day for plant-health monitoring. Stills only — no video, ever. Cloud pattern-recognition (leaf curl, pest, growth lag) is on the roadmap.
Under the hood it's established irrigation science — FAO-56 evapotranspiration, soil-moisture depletion tracking, and closed-loop dosing. The methodology is public; the implementation is ours. See the technical detail →
One controller, three configurations. Industrial drip-irrigation valves, IP67-rated outdoor enclosures, surge protection on every port, 12V DC input. Designed to outlast the crops it waters.
The brain. Eight native zones, with an expansion path to dozens of zones via wireless field nodes and accessories. Drives standard latching drip solenoids, 12V DC input.
The wireless arm. Solar+battery field unit for beds that sit far from the Controller. Drives up to 4 latching valves and reads up to 4 soil sensors per node, talking to the Controller over long-range wireless (LoRa), up to ~3 km line-of-sight (target).
Modular add-ons that plug into any Controller. Mix and match by what your beds actually need.
The same soil-driven control scales from a single raised bed to a small commercial block. If you grow it, HydroIQ can water it — on demand, zone by zone.

The short answer is usually yes — HydroIQ was designed around standard drip-irrigation hardware, not against it. Specifics by category below.
Works with standard latching drip solenoids — the standard for battery- and solar-driven drip. If you have common 24VAC valves, a low-cost coil-swap kit replaces the solenoid coil — same valve body, new coil. Standard 1/2″ and 3/4″ drip valve bodies are supported.
Industry-standard RS485 Modbus probes (moisture, EC, temperature, and pH). Our 4-in-1 soil probes ship with Pro and Enterprise. You can also bring your own — the bus is open. Bluetooth/Wi-Fi-only probes aren't supported (latency and battery problems in practice).
Wi-Fi out of the box. Cloud is optional — the Controller runs schedules and fertigation locally without internet. Cloud features (AI-assisted scheduling, remote access, camera analysis) require a Grove or Canopy subscription. Off-grid beds beyond Wi-Fi range are reached via the Hydro Node accessory over long-range wireless (LoRa) — the Node carries the bed-level data back to the Controller in your house or shed.
12V DC input (off any standard 12V wall adapter), or run the Controller itself off-grid on solar + battery with the add-on kit. Node accessories run on solar + a long-life rechargeable battery for off-grid beds — months between charges in typical Northeast conditions.
1,000+ pre-loaded crop profiles with FAO-56 Kc coefficients across vegetative, flowering, fruiting, and harvest stages. Vegetables, berries, tree fruit, vineyards, herbs, ornamentals. Custom profiles via the app for anything we missed. We're not the agronomy moat — see the section below.
Validated in Northeast US humid-temperate conditions (NJ alpha sites, three seasons). FCC and UL certification scheduled for 2026; CE/UKCA in Year 2 for EU expansion. Cold-tolerance and dust ratings for Western/Southwest US in the test plan.
There's an entire 70-year corpus of agronomic research sitting in FAO bulletins, university extension archives, and USDA databases. The math that says this tomato in this soil in mid-July needs this much water at this depth has been worked out by people far more credentialed than us.
HydroIQ is the box that finally implements it cheaply, on your fence, for your beds. We use FAO-56 Penman-Monteith for evapotranspiration. Kc coefficients from the published crop-coefficient tables. AOAC-equivalent NPK chemistry for Bloom cartridge formulations. OpenET for regional priors. USDA NRCS soil maps for the install defaults.
What we don't do: we don't pretend "smart NPK sensors" work — in-soil probes measure bulk EC and dielectric, not specific nutrient species. For real NPK you need a lab test or a wet titration, which is what Bloom subscribers get (3 included per year). The marketing might be greener if we faked it. The science is clearer if we don't.
HydroIQ ships through the same drip-irrigation channel you already work with. We're not asking you to learn a new ecosystem — we built the Controller around the valves, sensors, and install practices the trade already uses.

No annual hardware re-purchase, no firmware paywalls, no surprise tiers. The cloud is optional and cancellable; cancelling never bricks what you bought.
Base ($349), Pro ($599 with bundled fertigation channel), Enterprise ($1,999 with 16-zone native + multi-site). One-time purchase. 12-month warranty (Enterprise: 3 years), non-transferable.
The cloud layer for a single property. Unlocks the full crop catalog and automatic over-the-air firmware updates, plus remote access from anywhere. Adds AI watering insights — cloud recommendations that learn each zone over time and tune your schedule beyond what the controller computes on its own (rolling out as the cloud platform ships). Month-to-month is 3×; billing starts at Wave 1, cancel anytime. Your Controller always keeps running on local schedules.
The complete AI + automation layer — for serious single-property growers and multi-site operators alike. Everything in Grove, plus anomaly & leak alerts (stuck valves, flow anomalies, sensor drift), water-savings analytics (what you applied vs. what the weather actually called for), and automated seasonal reports. Manage one property or many from a single remote dashboard with fleet firmware management (live today); the analytics suite is rolling out.
A separate fertigation add-on — not a cloud tier — that pairs with any plan once you have the fertigation module. Cartridge nutrients delivered as needed, 3 lab soil tests a year, and a cartridge discount. The Bloom channel meters nutrients and verifies irrigation-line EC before and after each dose, so a silent injection failure or wrong cartridge is caught and flagged. (Full closed-loop dose control and in-line pH sensing are on the roadmap.) Cartridges are yours — cancelling doesn't claw back what we've shipped.
Wave 1 ships in 2026. The first 100 subscribers get priority shipping slots and $50 off their first HydroIQ Controller. We'll send build updates, alpha-data field write-ups, and beta-program invites along the way.
