Engineered for Serious Growers
The VPD Pro Relay isn't a humidifier—it's the bridge between your environmental control system and your VPD Pro units.
Serious growers running automation systems need reliable ways to control their humidifiers based on environmental sensors and controllers. The Relay provides clean voltage conversion and control integration, allowing your automation system to manage humidity precisely.
Built to the same commercial standards as our humidifiers, the Relay handles both 120V and 24V control signals, making it compatible with virtually any automation platform. Clean switching, reliable operation, and professional-grade components ensure your environmental control system works exactly as designed.
Whether you're building a new automated grow or upgrading an existing system, the Relay provides the professional integration component you need. This is how you connect precision humidity control to intelligent automation.
