Who This Is For
- You are centralizing your lighting control because managing individual timers across two rooms is a constant hassle.
- You are adding thermal protection because you need a failsafe to shut down lights if your ventilation ever fails.
What We Found
- The touchscreen response is snappy, which makes navigating dual-zone menus faster than using older dial units.
- We found the sunrise ramp-up feature reduces moisture spikes that happen when lights flip on in a cold room.
- The included 5-metre temp cords are long enough to reach the centre of most rooms without buying extensions.
What Users Say
- Users with perpetual harvests say the dual-zone control saved them from the cost of buying two separate controllers.
- Operators who had an AC failure say the thermal probes saved their crop by dimming lights before heat damage hit.

FAQs
How many lights can I control with one unit?
You can daisy-chain and control up to 100 lights per channel, for a total of 200 fixtures across two independent zones from a single Master Controller.
Can I manage two different grow rooms with one controller?
Yes! The dual-channel design is perfect for this. It allows you to manage two separate grow areas, each with its own unique schedule and settings, ideal for managing both vegetative and flowering rooms simultaneously.
What does the sunrise and sunset feature do?
This feature gradually ramps the light intensity up or down over a set period, mimicking natural dawn and dusk. This gentle transition can help reduce plant stress compared to a sudden on/off light cycle, leading to healthier plants.
How does the temperature safety feature work?
The controller uses two thermal probes to monitor the temperature in your grow spaces. If the temperature exceeds a preset limit (e.g., due to an HVAC failure), it will automatically dim or shut off the lights to protect your plants from heat damage.
