The WET Kit provides researchers with a powerful portable tool for assessing growing conditions in soils and substrates. The WET Kit measures and displays 3 important variables that influence plant growth: water content, temperature and pore water conductivity (ECp) the EC of the water available to the plant.
The kit comprises a WET Sensor, an HH2 Moisture Meter (readout unit) and a carry case.
Includes sensor calibrations for generic mineral soils, organic soils, sand soils, clay soils, coir (coco fibre), peat based potting mixes, greenhouse mineral soils, and Stonewool artificial mineral wool substrate (vertical and horizontal measurement).

WET Sensor
In just 5 seconds the WET Sensor checks 3 crucial variables that influence plant growth: water content, temperature and pore water conductivity (ECp), the EC of the water that is available to the plant.
- Measures water content, EC and temperature
- Measure directly within the root zone
- Quick controls of growing conditions
- Ideal for precision irrigation
The WET Sensor is used throughout horticulture, especially by soft fruit growers and for crops grown in protected environments, where correct growing conditions are critical to both yield and avour. The compact sensor can be inserted directly into the growing medium with minimal disturbance to either roots or shoots, and provides information for process optimisation, checking growing condition uniformity and precision irrigation.
