Telos Growcast Bluetooth Grow Light Controller

Run your lights from your phone, not a mechanical timer

The Telos Growcast is a Bluetooth lighting control module that turns almost any modern dimmable fixture into a fully programmable light. If your light has a controller port, it is close to guaranteed to be compatible: the Growcast includes RJ11 Type 1, RJ11 Type 2 and M-12 3-pin connectors, covering Maxibright, Lumatek, Dimlux and Gavita. Instead of a plug-in timer and a dimming knob inside the tent, you set the whole photoperiod from the Telos Mesh app.

Key Benefits

• Daisy-chains up to 50 lights from a single unit, so a multi-light room needs one controller rather than one per fixture.
• Sunrise and sunset modes ramp output gradually at each end of the day for a natural lighting cycle.
• Precise PPF dimming sets intensity against actual PPF output and wattage rather than a vague percentage.
• IP66 rated housing shrugs off the humidity, dust and splashes of a working grow room.
• Discreet by design - once the network is created the unit can be made invisible on Bluetooth.
• Firmware updates in seconds from the app.

Excessive Stretch and Wasted Watts

Lights that snap straight to full power drive excessive stretch early on and stress plants at every lights-on. Ramped starts and finishes ease the canopy into the photoperiod, while accurate PPF dimming keeps intensity matched to the stage the crop is actually in - a real help when young plants sit under a fixture sized for full flower, where too much light means slow growth rather than more of it.

How to Use

Plug the Growcast into the controller port on your light using the matching connector, then download the Telos Mesh app from the Apple or Android store. Tap 'add' to create a network and pair the unit. Set your day and night cycle, switch on sunrise/sunset if you want gradual transitions, and dial intensity in by PPF output or wattage. To add fixtures, daisy-chain them from the first light rather than buying a second module.
