Roots & watering
Uneven watering or dry bags
When one bag dries while its neighbour stays wet, start by comparing water delivery. Increasing irrigation everywhere can make the wet areas worse.

Why does a moisture sensor read dry in wet cocopeat?
Check installation and contact before letting the reading control irrigation.

Why the root zone matters
Air gaps, uneven hydration and local root growth can make a point sensor unrepresentative of a coir bag.
01 / OBSERVE
Three checks before you change anything
- Inspect placement against the sensor manufacturer’s substrate instructions.
- Compare nearby moisture at root depth and the bag’s weight trend.
- Check whether the sensing area sits beside a dry pocket, outlet or emitter.
02 / NARROW IT DOWN
What do you find?
Choose the closest observation for a suggested next check.
Poor contact or air gap
Reinstall following the approved procedure and establish a new baseline.
A genuine dry pocket
Investigate wetting distribution rather than treating the whole bag as uniformly dry.
No clear physical explanation
Check calibration suitability and ask the sensor supplier to assess the reading.
03 / TAKE THE NEXT STEP
Leave with something useful
Validate the sensor against plant and bag observations before restoring automatic control.
Keep in mind
Do not assume a factory calibration suits every coir grade and container.
