AC Infinity TERRAFORM 9 Grow Room Air Conditioner

The AC Infinity TERRAFORM 9 cools, heats, dehumidifies and circulates air in indoor grow spaces. The unit sits outside your grow tent and ducts conditioned air inside, leaving more room for plants. It delivers 2,600 W of cooling, 2,100 W of heating and removes up to 24 litres of moisture per day in dedicated DRY mode.

It’s rated for grow tents up to approximately 3 × 3 m. The size it can handle in practice depends on how much heat your lights produce, the temperature of the surrounding room and how well the tent is sealed.

How the four modes work

• Cooling helps manage heat from grow lights and warm weather. It also removes some moisture as it cools.

• Heating helps maintain temperature when the surrounding room gets cold.

• Fan moves air without active heating or cooling.

• DRY provides dedicated dehumidification, removing up to 24 L per day under rated conditions. Actual moisture removal depends on temperature and humidity.

Cooling, heating and fan mode share the same single-duct setup. For dedicated dehumidification, manually switch to the two-duct setup and fit the supplied drain pipe. The unit runs one mode at a time.

Set your target on the unit or control it remotely

Use the onboard controls to set a temperature or VPD target and choose from 10 output levels. VPD, or vapour pressure deficit, uses temperature and humidity to indicate how readily moisture can evaporate from plant leaves. The included probe measures temperature and humidity inside your grow space.

The TERRAFORM 9 works on its own. Connect a Controller AI+ or newer via UIS for adaptive switching between cooling, heating and fan, plus Wi-Fi app control, alerts, data logging and automation. The Controller 69 series, including the 69 Pro and Pro+, is incompatible.

Installation and drainage

Place the unit outside the tent in a ventilated indoor area and follow the ducting guide so rejected heat has somewhere to go. A window seal is included for compatible venting setups.

The self-evaporating drainage system reduces how often you need to drain condensate. Very humid conditions can still require drainage, and DRY mode requires the supplied drain pipe. Auto-restart restores the previous settings after a power interruption. The unit also has automatic shut-off protection if it tilts or overheats.

Full specifications

Capacity vs. power draw: The 2,600 W cooling and 2,100 W heating figures describe how much heat the unit can move. The corresponding rated electrical draw is 1,000 W for cooling and 800 W for heating.

Before first use: Keep the unit upright during transport and follow the manufacturer’s stated waiting time before switching it on. Follow the supplied clearance, ventilation, drainage and electrical instructions. The unit contains flammable R290 refrigerant, so keep it away from ignition sources and leave refrigerant servicing to a licensed technician. The rear fan may continue running at low speed after the compressor stops.
