TrolMaster Humidity Device Station / Humidity Control Module (DSH-2U)

The TrolMaster DSH-2 Humidity Device Station manages humidifiers and dehumidifiers with precise, automated control. After you connect it to a TrolMaster controller, the system adjusts humidity levels based on live sensor feedback — ensuring your grow room stays within the ideal humidity range at all times. This protects plants from moisture-related stress, mould, and slow growth.

Specially designed for the Hydro-X Control System, the DSH-2 supports any humidifying or dehumidifying device under the world voltage standard (100–240 VAC, 50/60 Hz), up to 10 amps. Important: Use with dehumidifiers that draw less than 7 amps to avoid current overload.
