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.

The Risk: Guesswork Leads to Disaster

Nutrient salt buildup or waterlogged roots damage crops before you notice. Without a dedicated drain sensor, greenhouse soil conditions remain invisible — nutrient buildup in the substrate goes undetected until crop damage is irreversible.

Uneven water distribution across greenhouse soil – problem solved by drain sensor monitoring
