Simply plug the Growcast into your light's "Dim In" port for immediate functionality.

Is the Telos Growcast suitable for my growing operation size? +

The wireless range extends up to 10 meters between devices and controllers.

What maintenance and safety considerations should I know about? +

The Growcast requires minimal maintenance thanks to its IP66 weatherproof rating and solid-state design. Always ensure grow lights are powered off before connecting the device.

What additional features can I access with the Telos Mesh app? +

The Telos Mesh app enables precise PPF control from 10-100% with dim-to-off capability, 24-hour scheduling with optional sunrise/sunset transitions, and the ability to control multiple Growcast devices simultaneously.

Network Lock mode stops the Growcast from sending public Bluetooth advertising packets, hiding your lighting network from nearby devices. When active, the status LED displays purple.
