The Invisible Problem
The Reality: Fixed irrigation schedules ignore micro-climatic changes and plant transpiration shifts.
Uneven Water Uptake
Micro-climatic variations across gutter rows create inconsistent transpiration patterns.
Fixed Schedules Fail
Rigid irrigation timers ignore real-time plant needs and environmental shifts.
Manual Checks Are Too Slow
By the time you spot nutrient salt buildup or waterlogged roots, damage is done.
Nutrient salt buildup or waterlogged roots damage crops before you notice. Without a dedicated drain sensor, your greenhouse root zone is a black box. Salt builds up and roots drown while your climate screen still looks fine, and you only find out when the crop tells you.
Uneven Distribution
Inconsistent water across rows
Root Damage
Waterlogging & salt buildup
Too Late Detection
Problems found after damage
Water Uptake Variation Across a Single Gutter Row
The Dual-Data Advantage
Two sensor systems working in perfect harmony — monitoring both drain water quality and live gutter weight to give you complete control over your greenhouse root zone
Drainage Analytics
Continuous lab-grade drain sensor monitoring of EC, pH, and temperature to protect soil health and root zone conditions in your greenhouse.
Weight Dynamics
Integrated load cells provide a live ‘weight profile’ of your gutters to track exact water uptake.
Solar Autonomy
Fully wireless, self-charging hardware that installs in minutes.
Operational Autonomy
Industrial-grade hardware designed for wireless, maintenance-free operation in demanding greenhouse environments.
Solar-Powered Independence
Adjustable solar array provides 100% wireless operation, eliminating the need for external greenhouse wiring. No power infrastructure required—just mount and monitor.
Industrial Load Cells
High-precision stainless steel plates designed to integrate seamlessly with standard gutter supports. Weather-resistant construction ensures reliable operation in high-humidity environments.
Wireless Data Hub
Centralized control box transmits lab-grade data directly to your grower’s dashboard. Secure encrypted connection with redundant data logging.
Stop Guessing. Start Steering.
See the dramatic difference in EC stability and resource efficiency
DrainSense resolves drain EC shifts under 0.3 mS/cm in real time. That is the tightest drain EC steering you can buy, more accurate than anything else on the market, so you catch nutrient drift before your crop ever feels it.
EC Stability Comparison: Traditional vs DrainSense
Traditional Irrigation
High EC fluctuations stress plants and waste nutrients
DrainSense Steering
Stable, flat-line EC with optimized dry-backs
How It Works
From installation to optimization – the complete monitoring cycle
Install & Mount
Mount load cells under gutters and install drainage sensors. Quick-connect wireless system – no complex wiring needed.
Continuous Sensing
Sensors capture EC, pH, temperature, drain volume, and gutter weight every 5 minutes – 24/7 real-time monitoring.
Wireless Sync
Data transmits wirelessly to the cloud dashboard via Private LoRa. Solar power ensures uninterrupted operation.
Automated Control
Feed continuous drain EC, pH and gutter-weight data into your climate computer — HortOS, Argus or Priva — so irrigation and dry-back adjust automatically to what the crop is doing.
