Spider Farmer 3 Pcs GGS Smart 3-in-1 Soil Sensor Pro
Take the guesswork out of indoor cultivating with the Spider Farmer 3 Pcs GGS Smart 3-in-1 Soil Sensor Pro. Designed for precision-minded growers, this 3-pack of industrial-grade probes provides continuous, live data directly from your plant's root zones. By linking seamlessly with the Spider Farmer Grow Genius System (GGS) ecosystem, these sensors empower you to automate your irrigation, manage nutrient levels, and prevent root rot before symptoms ever show above the surface.
Key Features
  • 3-in-1 Vital Tracking: Monitors Volumetric Water Content (VWC), Electrical Conductivity (EC), and substrate temperature simultaneously.
  • Substrate Tailoring: Features custom presets for Peat Soil, Coconut Coir, and Yellow Clay to ensure flawless calibration across various mediums.
  • Automated Irrigation Control: Pairs with the GGS AC5 or AC10 Smart Power Strips to trigger automated drip systems based on live moisture thresholds.
  • Expandable GGS Network: Connects up to six Pro sensors to a single GGS Controller to manage multiple plants or tent zones at once.
  • Remote App Analytics: View historical data graphs and receive instant dry-out notifications anywhere via the official Spider Farmer App.
  • Long Reach Infrastructure: Built with durable 3.5-metre cables to comfortably route through large tents or commercial multi-tier racks.
Real-Time Root Zone Insights
1. Volumetric Water Content (VWC)
Never under-water or drown your root systems again. The sensor accurately maps soil moisture from 0% to 100%. This helps you maintain the perfect dry-back cycles crucial for robust root expansion.
2. Electrical Conductivity (EC Tracking)
Keep your feeding schedules perfectly dialed. Measuring EC up to 20 mS/cm allows you to track salt accumulation in your media, preventing nutrient lockout and burn.
3. Substrate Temperature
Root temperature directly governs nutrient uptake. These probes track shifts between -40°F and 185°F to ensure your rhizosphere stays inside the metabolic sweet spot.

Best Practices for Accurate Readings
For the most accurate telemetry, insert the metal probe horizontally into your medium. We recommend placing it directly into your fabric pot or container at roughly 1/3 of its overall height from the bottom. This places the sensor deep within the primary root zone for pristine data collection.

See What Is Happening in the Root Zone

Take the guesswork out of irrigation and root-zone management with the Spider Farmer GGS 3-in-1 Soil Sensor Pro 3-Pack, designed to give growers real-time insight into conditions inside their growing media.

Each probe simultaneously monitors volumetric water content, electrical conductivity and substrate temperature. This makes it easier to track moisture levels, understand dry-back patterns and monitor changes in nutrient concentration around the roots.

Connect the sensors to a compatible Spider Farmer GGS system to view soil data through the Spider Farmer app. Up to six Soil Sensor Pro probes can be connected to one GGS system, making it possible to monitor multiple plants or different areas of a growing environment.

FAQs

Each sensor measures three important root-zone conditions: volumetric water content or VWC, electrical conductivity or EC, and substrate temperature.

No. The current Spider Farmer 3-in-1 Soil Sensor Pro measures moisture, EC and temperature. It does not measure substrate pH.

This pack contains three Spider Farmer GGS 3-in-1 Soil Sensor Pro probes, allowing growers to monitor several plants or different areas within a growing space.

Yes. When connected through a compatible Spider Farmer GGS Controller, soil data can be monitored through the Spider Farmer app.

Spider Farmer states that one GGS system can support up to six Soil Sensor Pro probes, providing the option to expand monitoring across a larger grow.

For accurate readings, Spider Farmer recommends inserting the probe horizontally into the growing medium at approximately one-third of the container's height, positioning it close to the plant's root zone.
