More channels, when your grow needs them. Mini, Mid and Max plug straight into the Nexus.
Your Nexus runs 2 channels on its own. Add a router for 2, 4 or 8 more — daisy-chain up to 8 routers for 66 channels in total, across as many as 16 rooms. One cable in, one cable out to the next.
2 channels. The smallest step up — add a couple of fans, a heater or a humidifier when one tent grows into two jobs.
4 channels. Drive circulation fans, dimmable lights and climate plugs together — the sweet spot for a fully kitted single room.
8 channels. Everything at once — every fan, light, heater and CO₂ valve in a sealed room, all from one hub.
Each router connects to the Nexus with a single cable, then passes a second cable on to the next router. Chain up to eight. Every channel is electrically isolated, so a fault on one load can’t take down the rest.
The Nexus treats every router’s channels as if they were its own — same dashboard, same schedules, same climate and lighting logic. Nothing new to learn. Add a router, name its channels, and you’re running.
Routers carry sensors too, so soil and air readings travel back to the hub down the same chain.
