AC Infinity AI+ Environmental Controller CTR89Q – Smart Grow Room Automation

The AC Infinity CONTROLLER AI+ (CTR89Q) is the most advanced environmental controller in the AC Infinity UIS™ ecosystem – and the first to use artificial intelligence to automate and optimise your entire grow environment. Rather than simply reacting to conditions, it learns from previous cycles to anticipate and prevent environmental spikes before they happen, delivering exceptional stability across temperature, humidity, and VPD.

Connect up to 8 UIS™ devices directly (or up to 32 with splitter hubs), including inline fans, grow lights, humidifiers, and heaters. Pair with the AC Infinity app via Wi-Fi or Bluetooth to access AI-generated presets, grow guides, scheduling triggers, and performance scoring. Programming is retained even when Wi-Fi is disconnected, so your environment stays stable around the clock.

Why Choose the AC Infinity AI+ Controller?

Most environmental controllers react to conditions after they’ve already changed. The AI+ goes further – it analyses historical data from your grow to predict and prevent fluctuations before they occur. For growers who want the highest level of environmental precision without constant manual intervention, the CTR89Q is the most capable controller on the market at this price point. Pair it with the full AC Infinity UIS™ ecosystem for a fully integrated, app-managed grow room.
