Greenhouse Environmental Control

Replace manual irrigation schedules with soil-moisture triggers, monitor PAR light across your canopy, and get instant alerts when weather events threaten your crop.

The Problem

Light variability across canopy

Without PAR sensors, you have no visibility into how light levels vary across the canopy or whether supplemental lighting is hitting targets.

Manual irrigation scheduling

Hand-triggering irrigation based on a fixed schedule wastes water and leads to over- or under-watering when weather changes.

Late detection of temperature swings

Nighttime drops or afternoon heat spikes can stress plants for hours before a grower notices during the next walkthrough.

Wind and weather events

High wind events or unexpected rain can cause structural damage or flooding, with no automated notification to the grower.

How LoopString Solves It

PAR light & environmental monitoring

Track photosynthetically active radiation alongside temperature and humidity to optimize your daily light integral.

Automated irrigation triggers

Soil moisture sensors drive irrigation rules — water runs when soil drops below threshold, not on a fixed clock.

Flexible scheduling

Layer time-based schedules on top of sensor triggers for complex irrigation and lighting programs.

Weather event alerts

Wind speed and temperature threshold alerts notify your team immediately when conditions approach plant-stress limits.
