Hydroponics Automation
Replace manual pH and EC testing with continuous monitoring and automated dosing triggers — so your nutrient solution stays dialed in around the clock.
The Problem
Manual pH & EC testing
Testing reservoirs by hand multiple times a day is labor-intensive and still leaves long windows where drift goes undetected.
Inaccurate manual dosing
Manually adding nutrients introduces human error and makes it hard to reproduce successful batches.
Root zone temperature drift
Water temperature outside the optimal range stresses roots and reduces nutrient uptake, causing yield loss.
Overflow and pump failures go unnoticed
Without water-level sensors and automated alerts, a failed pump or overflowing reservoir can ruin a crop overnight.
How LoopString Solves It
Continuous pH & EC monitoring
Live sensor readings update your dashboard every few seconds — catch drift the moment it starts.
Automated dosing triggers
Configure threshold-based rules that trigger dosing pumps when pH or EC moves outside range.
Water level & temperature alerts
Alerts fire the instant water level drops below threshold or root-zone temperature exceeds your limits.
Historical batch comparison
Query sensor history across batches to identify what drove your best yields and reproduce those conditions.
