Complete Canopy-Level Environmental Insight
Measure light, climate, and plant response in real time at the canopy level, eliminating guesswork and dialing in consistent, high-quality harvests.
Key things we want you to know
The Grow Sensor PRO is a professional monitoring system built for serious indoor growers. It measures light, climate, and plant response in real time at the canopy level.
Factory-calibrated before shipping. Battery or USB powered, with 2.4 GHz WiFi and offline data logging.
Free shipping.
One Sensor. The Whole Environment.
Most grow rooms rely on multiple devices scattered around the space. That creates data gaps and makes it difficult to see what the plant canopy is actually experiencing. Grow Sensor PRO measures key environmental signals together at the canopy level, where plant physiology responds to its microclimate.
Understand real-time relationships like:
- How light intensity directly impacts leaf surface temperature.
- How climate fluctuations influence Vapor Pressure Deficit (VPD).
- How irrigation events impact root zone dynamics.
What It Measures
1. Climate & Environment
- Air temperature
- Relative humidity
- CO2 levels
- Dew Point
- Atmospheric pressure
- Ambient VPD
2. Light & Photosynthesis
- ePPFD (Extended Spectrum PPFD)
- ePAR (Extended Spectrum PAR)
- eDLI (Extended Daily Light Integral)
Lighting is one of the biggest drivers of yield. Tracking PPFD, spectrum, and DLI 24/7 allows you to maintain precise light targets throughout every stage of crop development.
3. Plant Response
- Leaf surface temperature (Infrared sensor)
- True Leaf VPD (measured, not estimated)
- Leaf-to-ambient temperature differential
4. Substrate & Root Zone
Measured via SDI-12 substrate probe models (sold separately):
- Substrate EC (Electrical Conductivity)
- Volumetric Water Content (VWC)
- Substrate temperature
Note: All sensors are factory-calibrated prior to shipping to ensure long-term accuracy and precision.
Built for Real Grow Rooms
- Flexible Power Options: Battery life ranging from 2 weeks to 3 months (depending on sampling frequency) plus a dedicated USB power option.
- Connectivity & Off-Grid Security: 2.4 GHz WiFi with offline data logging so you never lose data if the internet drops.
- Mounting & Size: Tripod-mountable with a compact form factor designed for any grow space setup.
- Smart Home Integration: Native Home Assistant compatibility and full API access for custom automated setups.
Who It's For
Ideal for growers who:
- Manage indoor cultivation rooms or sealed environments.
- Run multiple plants, zones, or perpetual crop cycles.
- Make data-driven decisions to optimize VPD, lighting, and fertigation.
- Pair precision environmental data with high-performance media like our KiS Organics Biochar Soil Mix or Water-Only Living Soil.
This system may NOT be the right fit if:
- You grow outdoors exclusively.
- You are looking for a basic wall-mounted thermometer/hygrometer.
- You do not plan to track or act on environmental data trends.
