Take Complete Control of Humidity for Healthier Crops

Humidity plays a vital role in plant health, transpiration and disease prevention. The TrolMaster HS-1 Humidistat Station gives growers precise automatic control of compatible 24V commercial dehumidifiers, helping maintain ideal humidity levels throughout every stage of plant growth. When connected to a compatible TrolMaster Hydro-X controller, the HS-1 replaces a traditional humidistat and allows your environmental control system to manage humidity automatically without switching high-current loads directly.

Perfect for commercial vegetable growers, greenhouses and indoor cultivation facilities, the HS-1 helps create a stable growing environment that supports stronger plant development, reduces the risk of mould and mildew, and improves crop consistency. With simple plug-and-play installation, an integrated LCD display and seamless Hydro-X integration, it's an essential upgrade for growers looking to automate their climate control system.
