Trees & arboriculture
Specimen trees, palms and planted landscapes. Track conditions beneath the canopy while keeping the landscape free of visible sensor hardware.

GX-1F
The only invisible tree sensor solution.
Standalone. Wireless. Autonomous. Buried just under the surface, the GX-1F puts ground truth beneath trees, orchard blocks and vine rows — without visible equipment above ground.
Root-zone intelligence
Different landscapes. The same need for ground truth.
Farms & orchards
Explore perennial crop deployments by soil, irrigation zone and root depth. Use measured moisture and salinity context to support local agronomic decisions.
Explore the solutionVineyards
A mixed GX-1F and iQ1 deployment pairs buried Flex-cord sensing with above-ground SmartTower monitoring across vineyard blocks. The GX-1F stays invisible; iQ1 adds an elevated field presence.
Explore the solutionVineyards: GX-1F + iQ1
We mix GX-1F Flex-cord sensors and iQ1 SmartTowers on vineyards. GX-1F places its sensing element below ground at the selected root depth; iQ1 provides SmartTower monitoring with an elevated LTE mast. Both contribute to GAIN. The iQ1 is not a gateway required to connect the independently cellular GX-1F.
What happens below ground matters.
Four measurement types, reported every 10 minutes. The flexible cord positions the sensing element at a selected root-zone location; it is not a continuous scan of every depth along the cord.
Soil moisture
Volumetric water content at the sensing location — below-ground context for irrigation timing.
Soil temperature
Temperature where the roots grow, distinct from the air above the canopy.
Salinity · EC
Electrical conductivity provides salinity context alongside moisture and soil conditions.
Dielectric response
The soil’s electromagnetic response, reported alongside water content, temperature and EC.
Measurements become context through GAIN.
GAIN combines root-zone readings with weather and evapotranspiration context, location-specific learning, and alerts by mobile push, SMS and email. Your team owns the decision. Sensor-free SmartLocations provide predictions, not live measurements.

Evidence-led exploration
Five strong crop candidates to start with.
Almonds, avocados, citrus, wine grapes and pistachios are research candidates for root-zone monitoring — not proven GroundWorx crop results. Placement depends on soil, irrigation pattern, tree age and the active root zone.
Almond
University research already pairs root-zone moisture and salinity readings in microirrigated orchards.
UC ANR almond microirrigation research ↗Avocado
Irrigation timing and avoiding waterlogged root zones matter to tree health and yield.
UC IPM avocado irrigation ↗Citrus
Strong extension guidance for soil-moisture-guided irrigation, especially on sandy soils.
UF/IFAS soil moisture sensors for citrus ↗Wine grapes
Root-zone feedback supports deficit irrigation and fruit-quality decisions; buried hardware suits vine rows.
WSU soil moisture sensors for wine grapes ↗Pistachio
Valuable water-limited orchard; drought tolerance does not remove yield and quality risk.
UC pistachio irrigation and drought ↗University sources are background research, not endorsement or validation of the GX-1F. Readings support local decisions with an agronomist; they are not an irrigation prescription.
Start with the signal. Finish with verified readings.
The same 6-inch-wide hole taken down to the root-ball zone, a 1-inch pea gravel base, and a vertical sensor with the drainage hole down. The 44-inch flex cord runs up to the body at the top of the hole.
The key element of every install: the sensor prongs always go into perfect, undisturbed soil in the sidewall — never into loosened or backfilled soil.
Works with or without iQ SmartWell.
Standalone GX-1F deployment requires no well. The iQ SmartWell Edition supports a relocatable, flush calibration sleeve with RFID identification and BLE pairing. iQ SmartWell and its GX-1F Edition remain under development, targeting Q1 2027; this is not a guaranteed delivery date.
Explore iQ SmartWellBuild around your trees, not a generic sensor grid.
GX-1F hardware: $850 per sensor, with the first year of GAIN included. GAIN service is required; standard annual renewal is $325 per sensor. Sign a 3- or 5-year GAIN agreement and any GX-1A, GX-1F or GX-1S drops to $750 — $1,500 all-in per sensor over 3 years, or $2,000 over 5.
