The GrowControl GrowBase is a versatile environmental controller designed for serious indoor growers who demand precise regulation of their grow rooms. Featuring four configurable outputs, it manages a wide range of systems—from fan speeds (both EC and AC) to lighting dimming, CO₂ injection, temperature, humidity, and negative pressure control. Its flexible settings include sunrise/sunset light ramping, multiple event timers, and intelligent triggers to automate critical parameters. The unit supports EC-compatible fan control, allowing seamless integration with energy-efficient ventilation systems, and can handle diverse sensor inputs for comprehensive climate management. GrowBase Pro includes enhanced features like inrush current suppression that enables connections with high-powered LED fixtures, CO₂ dosing support, and integration with GrowControl’s IRCube leaf-temperature sensor for full VPD (vapour pressure deficit) control.
